W.L. Davis 1935 Salmon Creek, 8 mi. W Rogerson, Jwin Falls Co., Idaho. May 13. Left Berkeley, Alameda Co., Calif., May 11 at 1:10 P.M. in company with Elmes Aldrich and Howard Twining. Drove to Winnemucca, Nevada the first night, arriving there about 1:00 a.m.; a distance of 382 miles. Pulled off the road about 5 miles E of that town and slept. Heard a Mockingbird. We encountered heavy snow in the Sierras though the road was clear. About 6 miles east of Carlin we stopped at noon and ate lunch. While there we climbed to the top of some bluff that overlooked the Humboldt River and visited a Prairie Falcon's nest. It was in a natural cave and was reached by means of rope. Aldrich took a photo of the eggs (4) in situ and I collected the set which proved to have been incubated about ten days. Took a W-T Swift here and a Rock Wren. #1143. Drove on to this camp, arriving here about 7:00 P.M. Our present camp is at the north end of the Salmon Creek Reservoir.

WB Davis 1935. Salmon Creek, 8 mi. W Rogerson, Twin Falls Co., Idaho. May 13. about 200 yards south of the dam. The dominant plant is Artemisia tridentata which reaches as far as the eye can see. No trees, save for a single juniper. Below the dam, in a deep, precipitous- walled canyon, there appears to be a growth of willow bordering the slight stream that trickles there. Yesterday we encountered snow after we crossed the Idaho line, and noted that the higher peaks were all coated with white. There had been a slight snowfall here but when we arrived it had disappeared. However it was quite cold and the strong west wind made it quite uncomfortable. We heard four ravels calling from at least three different posts. I attempted to track one of them down but with no success. The topography here is that common to southern Idaho, consisting of lava-capped buttes, sharply cut off on one side; the other gently rising from the surrounding terrain. The reservoir

Found old dropping of past seasons, but none that were fresh. Did not see a single mammal; not even a Eutamias. However, I had fair luck with the birds. On the reservoir proper I heard and saw several Larus sp (probably californicus ); and in the rocks I succeeded in taking a pair of Rock Wrens and one ? Canyon Wren. Both species are near or actually in the nesting period as judged by the size of the gonade. A ? Canyon Wren was observed carrying what I took to be a worm in its beak. Since this seemed to indicate young birds in the nest, I did not collect him. An examination of the female indicate

The ova ranged in size from O down to o, and surely this condition would not occur in a brooding bird. Does the ♂ feed the ♀, or was the worm a stick for nesting materials). These two birds - Canyon Wrens - were new to me. The reddish brown back and breast and the contrasting white throat patch are distinctive. Collected in addition to the three wrens, a ♂ Chipping Sparrow and a ♀ Brewer Sparrow. Both of these were in the short sage on top of the c bluff, and appeared to be in small flocks - indicating that the nesting season had not yet arrived. The size of the ovaries bore this indication, too. Heard Vesper Sparrows. Saw two Ravens, a Sharp-shinned Hawk, a Western Red-tail, a Swainson Hawk, several Cliff Swallows, a Mourning Dove, and heard a Sage Thrasher. Horned Larks were noted along the highway yesterday just after we crossed into Idaho, and a few were around camp this morning.

V.B. Davis 1935. Salmon Creek, 8 mi. W Rogerson, Twin Falls County, Idaho, May 13, A Horned Owl was heard hooting from the cliffs below the dam last night and again tonight. Aldrich brought in a young maroonah today and reported a large colony on the west side of the canyon. Twining brought in a Ruby-crowned Kinglet and a 9 Cottontail that contained 10 embryos 62 mm. (rump-crown); also a young Pygmy Rabbit. This evening I set out 30 mouse traps - a few amongst the rocks at the top of the cliff east of the reservoir, but most of them in the sage where the soil was semi-sandy. These were spaced approximately 25 paces. I was talking with the keeper of the reservoir, Mr. Today and he informed me that he killed a Bob-cat (Lynx Cat) here last winter. He also told me that two badgers had been taken in this vicinity a few days previous to our arrival. He reported the presence of Skunk and Civet Cat.)

Irwin found a nest of the Raven today on a rocky ledge about two miles south of camp on the east side of the reservoir. Six eggs reported. I have failed so far to find any indication of the presence of Thomomys and Citellus. Mr. Molin. reported that the ground squirrels were quite common west of the creek around the ranches. Aldrich reported that he saw a chipmunk of some sort on the west side of the canyon. This canyon -- and reservoir appears to have some effect as a barrier in this particular area, though it is quite possible that in many places the dry stream of summer allowed crossing.

W. B. Davis 1935 Salmon Creek, 8 mi. W Rogerson, Twin Falls County, Idaho. May 14. I visited my traps this morning about 6 A.M. The sun was up an hour, but the piercing cold accompanied by a stiff SE breeze preserved all specimens. In an area of loose boulders amongst Artemisia I took three Perognathus parvus; amongst the rocky cliffs Peromyscus (10) were common, and in this same type of habitat I took one Reithrodontys. Five Dipodomys were taken in the semi-sandy sage covered areas. The following were my takes: Dipodomys ordi. 5 ♀ adults. Perognathus parvus 1♂ 2♀ " Peromyscus maniculatus 4♂ 6♂ " Peromyscus ? 1♂ " Reithrodonmys 1♀ " Stayed in camp until about 4:00 P.M. putting up specimens, then went down into the canyon below the dam. Here the canyon walls are nearly vertical with innumerable jute holes which offer excellent nesting sites for Swifts, Swallows, Hawks and Owls. Located the nesting site of a Western Redtail and a Horned.

One of the young of a family of Horned Owls had evidently fallen out of the nest and when I found it, it was huddled down amongst the rocks. I brought it to camp alive and this evening it ate four mouse bodies. The primaries are about two or three inches long, the tail feathers the same, and the rest of the body is covered with down save for the areas around the eyes. I examined several pellets found below the nest and found the following; Thomomys, Neotoma, Sylvilagus and Marmota and some unidentified bird remains. I have seen no indication of the presence of Thomomys in this area, but they must be here some place. Saved two parts of skulls of Thomomys. I collected one White-throated Swift, one Violet-green Swallow, one ? Sparrow Hawk and a Rock Wren. In addition I saw or heard the following: Mountain Bluebird, Prairie Falcon, Yellow Warbler, Great Blue Heron and Kingfisher.

Salmon Creek, 8 mi. w Rogerson, Twin Falls Co., Idaho, May 14, I found several old Rock Wren nests in the pot holes of the cliffs. There were hundreds of places where Neotoma appeared to be. I set several (about 8) traps in likely looking places amongst the rocks. There appeared to be evidence of porcupine and some large carnivore, perhaps a skunk or bobcat; the tracks of a bobcat were clearly evident in the soft dirt at one place. On the way back, just after sunset (8:30 M.T.) I saw and collected what I take to be a Pipistrellis while it was foraging over the dam. There were also several Myotis of some sort, but I was not fortunate enough to collect any. Will try it again tomorrow night. Aldrich reported having seen four sage grouse east of camp. They certainly are not plentiful. Swining had poor luck with the Marmots with his 16 gage, but did bring back a Song Sparrow and a Flycatcher from the canyon.

B. Davis 1935. Salmon Creek, 8 mi. W Rogerson, Twin Falls Co., Idaho. May '35. Went down into the canyon below the dam at 6:00 A.M. to look at my traps. Out of 12 traps, 10 of which were set at the base of the cliffs on the west side of the stream and two along the stream, I took 2 Peromyscus maniculatus 5♂ Peromyscus crinitus 1♂ Sorex sp. The Sorex was taken in one of the traps set in a mossy area where a spring comes out of the east side of the canyon. The trap was baited with rolled oats and there was good evidence that the shrew had eaten part of the bait. When I got to it, some water beetles had eaten part of the flank area. There should be Navigator shrews on the creek, but none was taken. The crinitus were all taken at the base of the cliffs. I found numerous places where they were occupying a habitat similar to that occupied by Meriones. They make little trails at the base of the cliffs where they are accustomed

Signs of Neotoma was abundant, but I failed to catch any. However, Swining caught two on a rocky outcropping about ½ mi NE of our camp. I saw some Porcupine workings in the willows and scat along the base of the cliffs. No other mammals were noted. I was fortunate enough to bag a White-throated Swift. They appear to be mating, judged by the aerial maneuvers the birds go through. Two – apparently pairs – birds flit here and there over the canyon and occasionally one of the birds would alight at and disappear into vertical crevices in the rocks. These place appear to be future nesting sites. The condition of the female indicated pre nesting condition. There are about a dozen birds using the first ½ mile of the canyon. Also took one Violet-green Swallow and two Cliff Swallows – the latter

Mountain Bluebird. The condition of the latter indicated nesting. The Marmots are occupying two types of habitat here (1) the Talus slopes of huge boulders, and (2) open, rather sandy-loam talus slopes where the burrows are very conspicuous. The old ones are very wary, much more so than the younger ones and as a result we have failed to take any old specimens. The following birds were noted: Osprey - 1 lone bird flew over the dam, Prairie Falcon - nesting on the East side of the canyon, Yellow Warbler Song Sparrow Flicker.

VB Davis 1935. Salmon Creek, 8 mi. W Rogerson, Twin Falls co, Idaho. May 15, Today we had high winds and rain in the afternoon and the sky remained overcast until after dark. As a result it got darker earlier than yesterday evening. I went down to the dam at 6:30 to await the arrival of the bats. I was interested to see what effect the daily fluctuation in intensity of light would have on their time of flight. Yesterday I saw 8:30 m.t. the first one at 7:30 P.M. (Pacific time) 8:15 m.t. Tonight I saw the first one at 7:15, indicating that intensity of light is a controlling factor. The flight tonight was very short as compared to the previous one. This is perhaps due to the cold; perhaps to cloudiness, but I believe it is the former. I was impressed by the fact that the Cliff Swallows were active, probably feeding, up to 7:10, then there was a lull of five minutes and the first bat appeared - a Myotis. Thus, there was no overlap in foraging times between the

Bats and the Swallows, both of which forage in the same area but complementary to eachother, I was fortunate enough to bag two of the Myotis, one a volans interior - badly shot up - and a darker - larger one that is certainly not a volans. Both were feeding - at least flying in the same area, and thus it appears that there must be some inter- specific competition for I could detect no differences in feeding activities. Tonight, for the first time this trip, we heard Coyotes. There appeared to be two of them on the ridge east of camp. The keeper here reports that he believes they are quite common. Irving & Aldrich reported Broad-tailed Hammers, Calliope Hummers, Solomie Warbler, Accubow Warbler, Junco's, Water Ouzels from the Canyon, and Caspian Tern, California Gull, Common Loon, Lesser Scap, Red-breasted Mergancere from the reservoir.

W.B. Davis 1935 I Mr. E. Hagerman, Gooding Co., Idaho, May 17. We moved camp yesterday, hunting as we went. Although there were no citellus near our last camp we found plenty of them near Rogerson and from there as far as the heavily cultivated areas of the Twin Falls Project, all that we collected and all that I noted in passing were oregonus. They were occupying the semi-arid areas near the "dry farm" lands west of Rogerson. From Rogerson on toward Twin Falls we found them near rocks, along the railroad right of way and in the Artemisia. I cannot account for their absence near our last camp for the soil was practically the same as far as I could see. Perhaps it maybe that food was lacking in that area. Three miles north of Holister we saw three sage hens. Drove into Twin Falls to do some necessary shopping and then drove out to this camp site. We are camped on the property of a Mr. Briggs on the

The river here is about 400 yards wide and of moderate depth. The canyon walls are removed some distance from the river and all of the available bottom land is taken over by agriculture, some hay is raised, but stock raising seems to be the main occupation. Numerous large streams arise from the ciffs on the north side of the river, one of which flows a short distance from our camp and forms a marsh of some extent where it meanders through the fairly level bottom land. In this marsh are numerous birds, ducks included and muskrats. I found numerous places this evening where muskrats had been active but set no traps; will do so tomorrow. We set out no traps last night as we got into camp too late. Today was spent mostly in putting up

There are none here and Mr. Briggs tells me he has never seen any here. This seems peculiar to me, but I suppose the extremely interrupted territory may have some bearing on this. Also there are no Citellus, apparently, in the river bottom area. They must be confined to the sage areas outside the cultivated lands. Mr. Briggs told me tonight that there were formerly "plenty" of beaver in the creek and a few in the river, but that poachers had decimated their numbers of late so that now there are very few. He reported that there is a dam across the creek near the place where it empties into the river. I expect to visit the area tomorrow to check for evidence of their presence now. I set out about twenty traps in the marshy area in likely looking places for Microtus; also

J.B. Davis 1935. 2 mi. E Nagerman, Gooding Co., Idaho. May 18, This camp is just above Upper Salmon Falls of the Snake River. Gooding County is on the north side of the river, Twin Falls County on the south. It is my purpose to collect on both sides of the river; all specimens taken are labelled as from Twin Falls County (south side) or Gooding County (north side). I looked at my mouse traps set in the marsh, amongst reeds and cat-tails and found only one Microtus (no. 1209) and two Reithrodontomy's (no. 1207-1208). A few of the other traps were set off, but not a thing in them. This was probably done by some marsh bird, perhaps Rails. On the way back to camp I collected a ♀ Willow Goldfinch (no. 1210), a ♀ Redwing (no. 1212), a ♂ Long- tailed Chat (no. 1211), and a ♂ Yellowthroat, the latter badly shot up. The yellow- throat ♂'s have established territories and the testes are of breeding size. I also found a nest with 6 eggs of the Cinnamon Teal. This bird is by far the commonest duck, and I should judge that there must be nearly 50 breeding pairs in this neighborhood.

W.B. Davis 1935 2 mi. E Hagerman, Gooding Co., Idaho. May 18. Next to the Cinnamon Teal the Mallard is next in abundance. Coots are here by the hundreds, and despite persecution by the hunters they are holding their own. In the afternoon I drove to the Roy Vader ranch just across the bridge on the south side of the river prospecting for Thomomys. Mr. Vader said he had plenty of them along the ditch bank in his alfalfa field and he was kind enough to go with me and show me where they were. He showed me places where they had undermined his ditches) and caused breaks in the water system. There was very little evidence of their presence in the alfalfa field proper. This is perhaps due to the frequent irrigations. Most of them were along the ditch bank. I made 13 sets within a distance of perhaps 1/4 mile. The burrows were small for the most part and the soil was sandy loam and of a light color; very easily penetrated by the burrowing rodents. Mr. Vader told me I could find

I drove over there and found them in abundance. They were occupying a stretch of rocky slope along the river where numerous small springs kept a strip of grass green and luscious. Numerous boulders were present which served to some extent as dens, though many of them had dug dens into the earth banks. I succeeded in killing four females and two young ♂; the last two were discarded. The meadow was "mowed" close at the time of my visit and dung was scattered all over the place. The young were about ¼ grown and in one case they were apparently still nursing. The young were more venturesome than the adults, and it was they in most cases that gave the warning signal. I was surprised at the ability these animals have in covering ground when on the run. They appear to flatten themselves to the ground as flipping their tail retreat to their

In other cases I sat for fully half an hour but none appeared. They like to flatten themselves on the top of rocks and in almost every case they were so placed that they could have full view of the lower country down hill), thus leaving their rears exposed. I took advantage of this and hunted from the top of the hill on which they were sunning themselves). Their food appears to be mostly grasses and soft herbs, but in one case I saw an old female up in an Artemisia eating the tender parts. Those we skinned (five in number, Aldrich got one at another place north west of camp about 1 mile) were quite fat save for one old female that was apparently still nursing young. Two of these, a ♀ and a ♂ were made up as study skins, the other three were dried stretched. I saw and collected one Cottontail in the same habitat as that occupies

Their workings were not so numerous as in Mr. Vader's field, and in most cases their burrows were from 12" to 18" below the level of the ground and in the field proper. In the evening I visited my traps in Mr. Vader's field and found I had collected one ♀, adult, with 9 embryos. The mammae were in 5 pairs, 2-1-2. Also at the same time I found the body of a Mephitis that Mr. Vader had killed and buried in the mud about a week ago. I unearthed the animal, sexed and measured it, and collected the skull. The stripes were broad and full length. There was much white on the tail. In the evening I collected a Screech Owl that was calling from a tree in Mr. Briggs' yard. I walked about under the tree quite a bit and flashed the light on the bird, but it just sat there and allowed itself to be caged. There are many Long-tailed Chats in this area; as many as

They have a very peculiar method of flight from the top of one willow to another, fluttering their wings and flopping their tails up and down as if they were loose appendages and often calling when in flight. Perhaps this is part of their mating antics. Stayed in camp most of the day putting up Marmots and Pocket Gophers. May 20. Same locality.

He also showed me where he had caught and left entire the bodies of two Spilogales on this (the north) side of the river about 100 feet up stream from the highway bridge. He caught them last winter in traps set in water at what he took to be the entrance to a Muskrat burrow system. Thus, the only way the "Civet Cats" could have been caught was for them to enter the water. He had set two traps side by side and caught the two Spilogales. The two skulls were in good condition and I collected them. He reported that these beasts were very common here last winter, but that the price was so low on their furs that they were never saved. He told me of finding a skunk den on the bank of a sandy-clay wash a short distance above his house. He kindly set two traps at the mouth of the burrow for me.

He claims that last winter he and his son trapped 22 skunks for which they averaged less than 50 cents each. When I visited my gopher sets at Mr. Seler's place I found only two gophers; the other traps had not been sprung so were left. This one, an old F, was more fuscous in color than the young one and to me darker in color than the old ones from south of the river. Also this female had only 4 pairs of mammae. Three new sets were made in his field. In the traps set in the marsh I caught no muskrats, but did get a S Virginia Rail and a S Sora Rail. Both were caught by the foot, the trap in each case breaking the leg in two. The feathers of the Virginia Rail were badly damaged so the specimen was saved as a skeleton. I killed a S Yellow-headed Blackbird.

I looked at my gopher traps yesterday morning and took one & on the south side of the river and two &'s on the north side, all three were saved. I looked at the set made for skunk and found a female caught by a front foot. There were two traps in the set and one had been buried by the animal so that I couldn't drag the beast to the water to drown as per Mr. Ebert's suggestion, so killed her with two charges of no. 12 shot in the hip area. This prevented her from lifting her tail and thus avoided scent. She looked as if she had been sucking young. Her den was dug into the bank of a clay-loam wash and had a good supply of green and dried litter about the opening. There was no odor around the den. We left this camp about noon with the idea of driving to Murphy to hunt ground squirrels. We stopped at Mountain Home to buy a few groceries and mail letters and from there drove to Grand View and then on to Creana, a post office station.

B.Davis 1935 Castle Creek, 8 mi. S Creana, Cwyhee Co., Idaho, May 22. about 22 miles west of Grand View and 18 miles east of Murphy. Here we talked with a Mr. Bachman, owner of the store and of several ranches and he informed me that I could find [illegible] in abundance at his ranch here on Castle Creek, so we slept at Creana last night and drove to the ranch here where we have established camp at the ranch house. There were no indications of the presence of Citellus between our last camp and Mountain Home. However, when I inquired at the office of the County Agent, I was informed that squirrels were being poisoned by the Bureau of Biological Survey near King Hill, at Smith's Prairie and at Mayfield in particular. They were reported as being quite a problem in the county. On the way south from Mountain Home on our way to Grand View we saw our first [illegible] about 4 miles south of that town. It was near this same place that I collected them last year. They were occupying an area of rather low astericea blue

Their high pitched squeaks, much shriller than that of C. oreganus apparently is quite distinctive for this species. The animals were very shy for the most part and sought cover at the slightest sign of danger and it was with some difficulty that Iwining and I were able to collect a small series of 8 specimens. Most of these were what I should judge to be yearlings; that is, not old ones nor young of the year. An old female and a young of the year were taken for comparison. I believe they do not reach full maturity until at least the second year, though doubtless they breed the second year, that is when a year or less of age. This one large colony, perhaps covering a couple of square miles or more in extent, some of which appeared to be deserted dry farm land, was the only one we saw on the trip over here. They seem to be isolated in colonies and are not

At Grand View we saw the horns and part of the skull of a Mountain Sheep that had come from the mountains near Silver City. There were also several mounted heads of Odocoileus hemionus that had come from the same area. I inquired at Grand View as to the status of Thormopus and was informed that they were abundant and a serious pest. We did not stop to trap because we were scheduled to be at Murphy by the 22nd. This would be an ideal place to trap on the two sides of the river, which at this place is about 150 yards wide, to test the effect of the river on speciation. I plan to trap the area on our trip back toward the east. About 7 miles west of Grand View we found a Lynx rufus skin tacked to the barn door of some rancher. He was not at home so we could get its history, but nevertheless Aldrich took a picture of it.

W.B. Davis 1935, Castle Creek, 8 mi., S Oreana, Owyhee Co. Idaho, May 27. There is a strip of Lower Sonoran zone along the Snake River which extends for some distance up the small creeks emptying into it from the south. This zone appears to be characterized by Greasewood as the dominant shrub, and in some cases associated with Rabbitbrush. The characteristic bird is the Western or Eastern Sagebird, particularly the former. All the higher country is dominated by Artemisia and is in, I should judge, Upper Sonoran zone. So far we have worked in no truly Transition zone, save perhaps the bottom of the canyon at Sabnow Creek west of Rogerson. At Oreana Mr. Bachman told me there were no ground squirrels of any sort in the valley -- that is, in the Lower Sonoran Life Zone, -- but that they were supposed to be quite common farther up in the foothills. He said, however, that there were Ammospermophilos, and coming over to the ranch today one was seen along the road. This is my first sight record this year, and last year

W.B. Davis 1935. Castle Creek, 8 mi. S Oreana, Cwythe Co, Idaho. May 27. I took a young one in the Lower Sonoran Life Zone just south of the river bridge north of Brumman. The river must be the northern limit of their range in this state, but I doubt very much that they go as far east as Twin Falls. Mr. Bachman showed us several fossils of woods, including two nearly perfect conifer cones. One looked a good deal like the cone of a Sequoia and the other a Pinus murrayana. Both had been found in the near vicinity. There were also Vertebrate remains. This morning I went for a walk around Oreana and found a single lead colored Bushtit feeding off the foliage of a Greasewood brush. I collected it as my first record for this state. The two fellows with me have both seen the species before at both our previous camps. Oreana is located on a small creek, Nort Creek, tributary to Castle Creek, and about 10 miles south of Snake River. The whole area is that of a typical lake bed - probably that of the old Idaho Formations. The mountains touched

The upper benches are Upper Sonoran and possibly up higher, Transition. The ranch at which we are camped is along Castle Creek, beginning at the point where it breaks from the foothills in a narrow, precipitously walled canyon and extending on both sides of the creek for a distance of perhaps a mile or so. The riparian growth is chiefly willow and wild roses. In this habitat were found Yellow Warbler, Lazuli Bunting, Robin, Song Sparrows and Yellow-throats and Western Warbling Vireos. In the area outside the limits of cultivation Atriplex and Grayia were the common shrubs, the former in dominance. This last area was practically devoid of bird life. The soil was clay-loam in the cultivated areas and appeared to be heavily alkaline in places especially outside the irrigated areas. I spent the greater part of my

The female had a nest in a tall sage (Artemisia tridentata) about 2'½ from the ground and it contained a single egg. In the afternoon I took a walk up the creek as far as the canyon, collecting an Eastern Kingbird and a Western Warbling Vireo. On the way back to camp I set 5 mouse traps in the Atriplex near apparently occupied burrows. These were placed about 25 to 40 ft. apart. I offered a boy five cents each for every large Thomomys he could catch; I supplied the traps and showed him how to set them. In the afternoon he brought in 5 specimens of Thomomys townsendii - a distinct surprise to me. I had supposed the gophers here to be the quadratus type. Now the question is: "Are these identical with those near Nampa?" If so, how did they arise or get across

I believe these will prove to be affiliated with J. nevadensis. I offered another chap 25 cts each for 4 Ondatra; I furnished the traps. He set them in likely looking burrows along the creek. This stream is very fluctuating in habit; last year there was barely any water, this year the water was so high that it probably did some damage to the young. This evening he looked at the traps and found nothing. There is a high range of rugged, now snow-capped mountains to the west and southwest of this locality. They are not named on our maps, but are locally known as the Owyhee Mountains. They appear to be quite rugged and about 8,000 or 9,000 ft. high. Silver City is in the heart of this range. The reported dominant trees are Pseudotsuga, Juniperus, and Mountain Mahogany (Cercocarpus).

W.B. Davis 1935. Hills 6 mi., W of Murphy, Owyhee Co, Idaho, May 23, This morning I looked at my traps and found nothing. I cannot account for this lack of a catch. Aldrich caught only 6 out of 30 traps set; and Twining 1 out of 30 trap nights. The territory appeared to be occupied but perhaps by some diurnal mammal. One of the boys brought in a muskrat that he had caught and the gopher traps yielded three, two of which were young and were discarded. We left this camp - at Castle Creek - about 4:00 P.M. and drove to this locality by way of Oreana, Linkers Creek, and Murphy. This territory here is in the foothills west of Murphy. The whole area is covered with Artemisia tridentata and trriples. There are a few Cercocarpus and quite a few Grayia. In the gulley through which a small creek is now flowing, but which dries up during the summer, are willows and wild roses. On the way over we kept a constant watch for Citellus and found one small colony between Oreana and

Sinkers Creek - about three miles east of Sinkers Creek, I should judge, we stopped and got one shot, but missed, the animal getting down into a burrow. We remained in the vicinity for about twenty minutes, Aldrich and Twining hunting while I attempted to dig out a burrow system. We could hear their high pitched squeak, but were unsuccessful in our attempts to bag some. The burrows here were for the most part about 60 mm in diameter and about 6 inches below the level of the soil. There were five exits to the system I was working on and each had a tunnel meeting with others which in turn entered a burrow that ran deep into the ground - I dug to a depth of two feet and it was still going down. It is this animal that is responsible for the big "colonial" mounds that one finds as often - usually deserted. At each entrance there is a little side, blind burrow - a vestibule - into which the squirrel can scurry for a hasty retreat and

It is in these vestibules, I believe, that the squirrels sit and "chirp" their warning notes which are distinctly heard, yet the animal itself is not visible. This colony was located on the top and east slope of a small gentle rise in an area where the Atriplex was very low - about 10 inches - and in soil that was sandy loam - and very easily worked. I had no difficulty in digging out about 20 ft. of burrow in a very short time - about 10 minutes. This was the only colony we have seen on this side of the river. we stopped at Murphy and inquired about the presence of ground squirrels in the Murphy area. A Mr. Kelley told me that about 12 years ago the squirrels were very abundant in all the area, but that some sort of disease had wiped out all those in the lower altitudes so that now all that is left are some colonies in the upper reaches of

In the afternoon I took a circuit through the hills to see if I could locate any fresh signs of Citellus leucodon. This camp is near the type locality. Twining and Alrick did the same. Each of us found abundant indication that they have been in this area, but all the mounds are old and the burrow entrances are caved in or covered up. None of us found any squirrels)

Since there are apparently none here, we plan to leave tomorrow and go about 14 miles south of Murphy into higher country. There is very little here in the way of animal life. I saw three Lepus and one Sylvilagus and one Eutamias minimus today on my hike. Birds are rare save near the cabin where they have congregated near the only available water. There are plenty of Neotoma in the rocky ledges near here and last night and today we trapped out a family that was occupying this cabin. There were the old ♂, tho ♀ and 5 young, all of which were caught. Only the adults were saved. We have set out no traps save those in the cabin since we have been here.

W.B. Davis 1935. 368 5 mls. SE Murphy, Owyhee Co., Idaho. May 26. We found no Citellus so drove back to Murphy and inquired again for these squirrels. Again we were told they could be found on Reynolds Creek and also that they could be found here. We chose this place for the presents. We stopped at the Gifford ranch about 1/4 mile from our camp and inquired for squirrels. He told us there were none, but that there were plenty of them at Reynolds Creek where his folks live. He said he had many big gophers in his field though, so we stopped and I set out 11 sets while the boys hunted for Citellus. They succeeded in killing three and in seeing several others, when Mr. Gifford saw the squirrel he said, "Oh, I didn't know you meant those little things." This statement leads me to believe that the Citellus at Reynolds Creek are Oregonus. I hunted for about an hour taking several Horned Larks - a very abundant bird in this area - a Dolmiec Warbler, a Brewer's Blackbird

The Iolmis Warbler was found in a Sarcobatus bush along an irrigation ditch; a most peculiar locality for this species it seems. The Horned Larks were paired and flying about the alfalfa fields. I found one nest with three eggs. It was placed in a depression in the ground under a spreading dandelion. Kneighrde (Arkansas), English Sparrow, Say Phoebe, Mourning Dove, Raven, Sage Sparrow and West Meadowlark were seen or heard at this locality today. I visited my gopher sets after they had been out about two hours. I started at the last set first and found nothing. The same was true of the next three. Out of the remaining seven sets I took 6 gophers (Thomomy Townsendii), three females and three males. Two of the males were huge and were breeding. One of the females contained six embryos about 12 mm. These animals were taken in clay loam soil in an alfalfa field. Their

W.B. Davis 1935 5 mi. SE Murphy, Cuyhee Co., Idaho, May 25, Mounds appear to me to be much larger than those made by T. bottae. The burrows were large, about the size of my forearm, and were about 14 inches on the average below the surface of the ground. Citellus leucodow appears to me to be much like Citellus idahoensis but they are much more shy in their habits and are colonial. They construct huge mounds with many burrow entrances and it appears that more than one squirrel occupies each mound area. Twining believes that each represents a single burrow system and that when more than one squirrel is present, it represents a family affair. Aldrich said he saw three apparently adult squirrels at one mound. I am inclined to believe as does Twining. These mounds average about four feet across and appear to be honey-combed with surface burrows. They are very common in this area but most of them are old.

W.R. Davis 1935. 371 5 mi. SE Murphy, Owyhee Co., Idaho, May 25, I talked with a Mr. Neslo, a rancher who has been here for many years, about the squirrels. He told me that he had seen only two of them this year, but that several years ago they were very numerous. It is his belief that some sort of epidemic broke out among them and wiped them out. The presence of so many deserted burrow systems seems to bear this statement out. He also said that poisoning had been resorted to. They appear to prefer areas in which there is short Artemisia and Atriplex, particularly the latter. In some areas they appear to have inhabited purely Artemisia covered tracts. The only we found today were chiefly in Atriplex areas. Perhaps the squirrels eat the seeds of this plant. I took a short walk through the area in which the squirrels were taken, and in which more were known to be present and failed to see a single one. They are extremely timid and their rate of recovery when

We dug up a Dipodomys burrow this evening. Found a nest, composed chiefly of rabbit fur and tufts of hide, but no mouse. Perhaps we missed it in some side burrow that had been plugged. The burrow averaged 12 inches deep and about 60 mm. in diameter. There were numerous branches and side pockets. Numerous heads of some sort of Brassica were found strewn along the burrow. Twining and Aldrich set out each 30 mouse traps this evening. They reported numerous sign and Aldrich reported seeing two Dipodomys. The whole area here is a big flat table-like region and part of it is under cultivation; the water for irrigation coming from Lunker Creek. Due to severe droughts during the past few years many of the ranches are deserted. At one time there were 8,000 acres under cultivation. Now

Murphy, Owyhee Co., Idaho, May 25, there are less than 800 (vide Mr. Neals.), Artemisia, Atriplex and Grayia are the chief plants, The first two being dominant and the latter usually found in association with the Atriplex. All the soil is of the clay loam type and some of it appears to resemble adobe. There is very little alkali present. Amargosa is the dominant herb in this region. It is found in large areas and from a distance looks like a field of grass. There is very little grass to be found, and what there is, is found in scattered very small patches, the plants being well spaced. The weather for the past two day has been ideal. The sky has been clear, the sun hot, yet a prevailing westerly wind has made it not unbearable. Tonight the sky has clouded over and it looks like rain.

Stayed in camp until nearly 3:30 P.M. making up specimens. From that time until 6:00 P.M. Twining and I hunted for Citellus leucodon in the low Atriplex. There is quite a colony present in front of Mrs. Clifford's ranch, but we have been unable to locate them any other place. It is peculiar how these squirrels seem to be congregated in a restricted area about 200 yards in radius while the rest of the territory appears to be as favorable. In the surrounding territory there are old mounds, probably made when squirrels were more abundant. Another alternative could be that the colony as a whole might gradually migrate due to the expansion of the area by the young and the old squirrels dying off leaving the old home site vacant. We succeeded in killing 11, I 5 and Twining 6. However, there were only two that could be considered adults. Most of those seen were young of the

These (leucodon) lack the light cinnamon coloring on the under side of the tail and the general color appears to be lighter, less brown, and the tendency to dappling less prominent. There are two color phases found in the young; a very light silvery gray and another phase where more brown is present. They seem to subsist off the green herbs and off the tender tips of the growing Atriplex. I found one today that was feeding on the buds and seeds of Atriplex. It is not uncommon to see the animal perched in the top of a low Atriplex where it doubtless feeds in part and where it can the more easily scan the horizon. Again I emphasize that these animals are very shy and wary. Only the young will allow one to approach within gun shot range. The one old female I shot saw behind a brush and sat there partly screened

Their colors blends in well with that of the substrate and with me, I must rely upon some motion to really detect their presence. I set out two steel traps in the runway near the entrance to the burrow. At 6:00 P.M. I had caught nothing. I also set a rat trap, well covered save for the pan, at the entrance of a burrow into which I had seen a squirrel disappear. About an hour later when I visits the set I had caught one by the foot. It was still alive, but died shortly, probably due to some internal injury that was not evident from the outside. I set out four more rat traps at the burrows into which I had seen squirrels run. These were left out to be collected tomorrow. We wounded several that got down into the burrow before we could reach them. We attempted to dig them out but found that the burrows, save for the sub surface runs and

We have been unable to take our old mole so far. Doubtless they are still out - not in hibernation. We found them active outside the burrows up to 6:00 P.M.

There is a colony there occupying an area of about 500 acres. They were very wary and I found the best way to get them close to sit quietly by a mound and wait for them to appear. This took about 15 minutes of waiting on the average. By this method I succeeded in shooting four of them, one old ? and 3 young - 1? and 2?? . The latter were discarded because of small size, and also because the skull had been shattered in each case. One is able by this means to get within very close range, often too

I was able to make several good observations of the animals when they were too close for shooting. The usual thing to occur was that while watching a mound a squirrel would suddenly appear and standing on its hind legs, with the tail out behind on the ground as a prop and the front legs folded over the chest, it would quickly note my presence and utter a high pitched "chirt". This single note was very similar to the single note call of the Horned Lark and when the larks were calling - as they were today all around me - it was with difficulty that I was able to distinguish the two. The call of the squirrel is much more metallic. The squirrel would stand in this pose, perfectly balanced for as long as five minutes, actual timing, and then it would lower itself and instantly resume the standing pose. The usual site to stand, at least while I was present, was

In either place the squirrel was difficult to see from any distance. The belly and side coloring of the animal blends in perfectly with the environment. I marveled at the effect the light side stripe between the darker back and belly color had. It seemed to break the animal in two - disruptive coloration - and the camouflage was as nearly perfect as I have seen in nature. Besides the sharp single notes chip uttered at intervals of from 10 to 70 seconds, the animal has a peculiar low in volume but very high in pitch sort of squeak. It is unlike any other squirrel note I have heard save for Citellus idahoensis across the river. Even so, the note of this animal (Neurodes) seems to me to be higher in pitch and fainter.

He came back to the car to get the rifle, but when he got back the badgers had left the area and could not be found. Indications show that the badger must take some toll of this squirrel. I have found numbers of badger holes where they have been digging into leurodole burrows. There is a peculiar arrangement of the nose pad, when the animal wishes it is able to close the nostrils by pulling the nose pad down over them. This may be of some advantage to animals living in such an area where the dust is as fine as flour. These, like C. idahoensis have three anal glands, two lateral and one ventral. From a manipulation of the animal it looks as if there were extruded, and probably some scent deposited each time the animal defecated. Just what this function is, I do not know. These glands

Aldrich also found Citellus pregomes in numbers at the ranch on Sinkers Creek. They had their burrows in the Artemisia and tall sawgrass and foraged in the alfalfa field.

The fact that they are found only along the creek here seems to bear this out because the creek offers the requisite habitat, namely green herbage and the nearness of water. These two items are apparently not vital to the well being of C. leucodon. The latter subsist on the green parts, especially buds and seeds of the Atriplex. The stomach contents one one I examined today was entirely of the buds & tender tips of Atriplex as far as I could detect, I believe C. leucodon is more common than one would suspal in this part of the state. They are so reticent that it is only with determined hunting that one is able to see them. Fresh mounds are a good indication of their presence. I set 30 mouse traps tonight in Artemisia tridentata that is bordered by Atriplex. Also have three rat traps out for Rattus,

W.B. Davis 1935. 384 2 mi. S Melba, Canyon Co., Idaho, May 28, This morning I looked at my traps at our camp 5 mi. S of Murphy and found only a single young Peromyscus which I discarded. I believe the rodents were living more in the open. We spent the morning making up specimens and broke camp about noon and drove to Reynolds Creek about 14 miles west of Murphy and from there to Melba and then to our present camp at the ranch of a Mr. W.S. Pline. Our camp is at the north end of a big volcanic butte, whose side toward the river has numerous cliffs. The small valley to the north is under cultivation, alalfa being the chief crop. No native trees other than willow and cottonwood. At Reynolds Creek we stopped at the Adams ranch and collected for about four hours. Citellus oregonus were numerous and we took 11, saving only four adults. Aldrich set out 6 gopher sets and took two & quadratus and found one & dead, the skull of which was saved.

W.B. Davis 1935 2 mi. S Milla, Canyon Co., Idaho, May 28, was born and raised on that ranch about mammals in general and particularly about Citellus leucodax. He said that they were very abundant in the foothills along the Murphy- Reynolds road several years ago, but that he believed some sort of disease wiped them out. He called them the "Sage-brush Squirrel" and described them and their actions perfectly. He said they had never been in Reynolds Creek Valley to his knowledge but that they were common, or used to be between the Snake River and the foothills. When we drove through that area we stopped at ideal leucodax territory and found old mounds and very few fresh digings indicating that a few of them were still to be found there. However, we saw none, but then it was after 6:00 P.M. when we were in their territory.

He said that along the river north of Reynolds Creek that the big blue (townsendii) gopher was the common one. Mr. Adams was alert, though apparently inclined to laziness, and his statements concerning the mammals are, I believe quite correct. He said, also, that there were few skunk, but many coyotes and just a few badgers in the valley. We also stopped just south of the river and inquired about Thomop and Citellus. One rancher whose name I didn't get said he had a few gophers, but that he, like his neighbors, had them pretty well under control. He said he had seen no leurodon but that an animal whose description fitted Ammospermophilus perfectly was to be found in the 'grease wood' area. We didn't stop to investigate because it was late and we wanted to make camp and set out traps yet before dark. Twining and Aldrich each set out 30 traps among the rocks of the cinder butte.

These were collected 5 mi. S of Murphy. At Reynolds Creek I collected a sample of the cottonwood and also a ♀ & a ♂ willow. This morning we arose at 5:30 for the first time in several day and Twining and Aldrich looked at their traps. Peromyscus maniculatus was the larger portion of the catch, 8 of which were saved and I put them up. One Reithrodontomy's and three Neotoma completed the catch. One Neotoma only was saved. We put up specimens until noon and then I took the car and the gopher traps and drove to the south side of the river to look for gophers. They were few and far between, each farmer having checked them extremely well. I drove to the Bernard Ranch, 2 miles west of the mouth of Reynolds Creek, and collected the greater part of the afternoon. I talked with a Mr. Ragains, Melba & Route, who now runs the ranch about squirrels and gophers. He informed me that the 'Whitling'

Mr. Ragains said that he had two kinds of gophers in his fields but that he and the dog kept them down to bed rock. He said one kind was the little brown gophers and the other one is the big blue one, indicating Z. quadratus or T. townsendii. I found only one fresh burrow and made one set. An hour later when I returned I found the trap set off but only a few hairs in it. These were from a T. townsendii. Mr. Ragains also told me that the "white-tailed Squirrel", Ammospermophilus was to be found there. This sow had caught several of them last year. His descriptions of Ammo. were quite accurate. He did not remember having seen C. leurodon. Reported that muskrat and Skunk were quite common. He showed me a skunk den, but I had no still traps with me. I took a walk in the foothills back from the river (south) and failed to locate any Ammo. but I did find and collect one C. leurodon. It was

I could find no burrows and I believe the animal must have wandered down there from the Atriplex only a short distance away and in which there were a few burrows. It made no sound at all, but merely hid in the underbrush through which I had to shoot to collect it. When I got back to camp I compared this squirrel in the flesh with several C. idahoensis which Twining had collected, and find them distinct. C. leurodon has yellow teeth, idahoensis white, the size is about the same; idahoensis has a bushier tail tinged with rufous underneath, leurodon lacks the bushiness of the tail and the rufous color underneath. However, there is a tinge of cinnamon on the under side of tail in leurodon as both the tail and the hind foot are smaller; the nose pad is about 1/3 as wide; the front and hind feet are whitish save for a rusty colored blotch; the claws of the front feet are stenderer and more curved;

I collected several birds at the Bernard ranch: Bullock Oriole, Western Tanager; Cliff Swallow; Violet-green Swallow; Yellow Warbler. It started raining yesterday afternoon (May 29 - written morning of the 30th) and continued all night. Looking the ground to a depth of about 3 inches. We set out no traps on account of the rain. Citellus idahoensis and Marmots are quite abundant here. Three of the latter, 1 ♀ ad with the posterior half of her body devoid of fur, and two younger ones. Six idahoensis were taken. These squirrels are living in single mound burrows on the butte here. Their note is usually a series of a whistled 'lee-lee-lee-lee'. That of leurodon is either a single note uttered at intervals or a low 'whisper' whistle. That of oregonus is a decided loud whistle. The plant association in which idahoensis is living here is mixed Bromia, Atriplex and Artemisia. The soil is clay-sand for the most part.

I was informed that - all the gophers were the large bluish-gray I, townsendii and that "Lago brush" squirrels were to be found about three miles south of town on deserted dry farm areas. We drove out there and found them in abundance. They were living on bare, save for grasses and herbs, ground devoid for the most part of Artemisia. Each squirrel has its own burrow and they are simple single ones with a small mound thrown out to one side. The burrows about are 60 mm. in diameter and usually slant about 45°, going down at least two feet. The ground was too hard for easy digging so no system was dug out.

It was still alive, having been caught by a rear foot though nearly dead from exposure. I brought it to camp and wrapped it in heated clothes and now it appears like it will survive. The injured leg is useless apparently, we offered it a piece of carrot and it eats a few bites. It utters a peculiar whining call when handled.

This squirrel, it appears to me, prefers an open area to that covered with Artemisia. There is Artemisia growing near here in which a relatively few number of squirrels live. Most of them are in areas where the grass is about two inches high. They sit up in picket pin fashion when one is at a distance and utter their "lee, dee, dee" whistle; then as one approaches closer they drop on all fours, usually with the head toward the burrow entrance ready to retreat if one approaches closer. Usually when they are shot and not killed out- righ, they kick their way or crawl, into the burrow and are lost unless one wishes to do considerable digging. I spent most of the day making up skins.

On occasion their burrows were found at the base of Artemisia but the general rule was the more open ground where visibility was greater. These animals I believe rely to a large extent upon their eyes - rather than ears - as the means of receiving warning stimuli. I have topped a little size cautiously so as not to make a disturbance, and invariably the warning "lee' lee' dee' du'" was sounded. Some use the Artemisia as look out posts; others the tops of the mounds near the burrow entrances. We were told by the County Agent of Gooding County that squirrels were to be found commonly throughout the county - the short-tailed small ones". We found none after we had collected the four 4 mi. E of Gooding. They are doubtless found in the desert area between Shoshone and Rupert.

W.B. Davis 1935. Elba, Cassia Co., Idaho, June '2. I remember seeing squirrels there in 1918. On my way over here from Rupert on the 5L I collected a single young squirrel which appears to be C. [illegible] There is quite a colony near Cottrell, about 10 miles east of Elba. They were living on an area devoid of Artemisia, but one heavily covered with grasses. The typical weak leurodow whistle was given by these squirrels, but their burrow systems were lacking in the big mounds found at the type locality of leurodow. Here at Elba I find that C. oregane and C. armatus meet and overlap in their ranges. Each appears to occupy the same type of habitat as far as I can see. Each appears to be limited to watered areas and both can be taken on this ranch, although I have never taken the two in the same limited area - the territory of a colony. C. armatus is the common one on this ranch and its range extends west as far as Mt. Harrison at least. I found several individuals of

All are quite fat. Thomomys quadratus are scarce on this ranch; the cause for this, I believe is too much water. The chief crop is marsh hay which requires a good deal of water and the gophers are limited in areas along the ditches and in one high piece of ground. I took on two occasions an old & and a & in the same burrow system - probably correlated with mating activities. The &'s were certainly in the breeding season. All &'s had 4 pairs of mammae and none contained embryos. June 8 was spent in hiking up Mt. Independence. I got nearly to the lakes and collected few birds - Golden-crowned King let, Cassian Purple Finch Mountain Chickadee and Audubon Warbler & Junco. Saw only two of the lact, although the trip was made specially for them. I saw two mule deer - no antlers - and one Marmot.

In Brew Canyon - the canyon through which Cassia Creek flows from Mt. Independence, the dominant trees are Alders lower down and Quaking Aspen. About half way up the canyon evergreen trees - Pinus murrayana, Pseudotsuga taxifolia and Abies monticola are common on the north-facing slopes and in the bottom of the canyon along the creek. On the south facing slopes Mountain Mahogany is the dominant shrub. On the lower hills east of Elba, Juniperus utahensis is the dominant tree - Artemisia being interspersed and going to the top of the ridge. At higher altitudes on Mt. Independence, in association with the evergreens is a species of Arctostaphylos which forms a dense underbrush in some areas. My impressions of life zones)

The whole areas between the river and the mountains to the north and to the south is Upper Sonoran - Artemisia tridentata being the dominant plant. However, this plant is also found - stunted in growth - higher on the mountains. The Transition Life-zone is found in the canyons on the mountains to some extent, but here we find Canadian on the North facing slopes and Upper Sonoran on the south facing slopes, the bottom of the canyon usually being a mixture of the two.

On June 9 I rode up Conner Canyon, a canyon carrying a creek of the same name which drains Mt. Harrison on the south east. The south facing slopes of the ridge between Conner Canyon and Ella is devoid of trees save for a few junipers. Numerous "wild Sunflowers" were in bloom and these, along with the Artemisia tridentata formed the cover. "June Grass" was plentiful. In the canyon - Conner- the riparian growth was willow, alder and Quaking aspen, the latter being dominant and in groves higher in the canyon. On the north facing slope at the head of the canyon, Pinus murrayana and Pseudotsuga taxifolia were to be found in clumps of several acres in extent. On the south facing slope near the head of the canyon were a few Mountain Mahogany. I went up there particularly to get Marmots, but saw only two, both

They were living in the rock slides chiefly, but on the top of the ridge between Conner Canyon and Elba I found them occupying burrows in the open ground in the vicinity of flat shale-like rocks. In Conner Canyon I collected one Citellus armatus, but I am sure I saw an oregonicus. These two, I believe are distinct species and, I believe, are occupying the same ecological niche in this zone of overlap near Albion. There is still considerable snow_ on the ground in protected areas. Near one of these I "jumped" a Snow-shoe Rabbit - Lepus townsendii - and it went jumping away over the snow in a manner much like that of a deer. She was collected and contained 8 embryos which were nearly ready to be born. The eyes were open - of the embryos - and there was a considerable growth of fur. One was made up into a study skin.

It appears to me that the Mountain Chickadee ranges higher zonally than does the Long tailed Chickadee. I heard dozens of Ruby-crowned Kinglets singing in the tops of the Douglas Fir. I heard one Junco, but was unable to collect it. On the way back to camp I jumped a deer and a Mountain Lion. The latter was near the site where the deer had been bedded down and when frightened it trotted in long easy strides across the ridge and down into Cassia Creek Valley. It is reported - Mr. Wickel and others - that a few have given some trouble with the cattle the past few years. For the past two days I have been hunting squirrels here at Elba. Both O. bregmaeus and arnutus are here, and I believe are occupying the same type of habitat.

W.B. Savo 1935. Rupert, Minidoka Co., Idaho June 15. For the past three days I have been hunting squirrels in Raft River Valley at the river just east of Malta only C. armatus was to be found. I was hunting there late in the afternoon of the 13th and at that time of day the big fat squirrels were stretched out on the mounds near the mouth of the burrows running themselves. I collected two such and they were extremely fat. Those collected at the same time of day that were running around and feeding were young ones and not so fat. At a deserted ranch about 2 mi. S of Malta I found only C. oreganus. They were numerous and quite easily approached. No water save that used to irrigate a nearby alfalfa field was available. This is about the third time I have found them far from a flowing stream of some sort. I don't believe the squirrels require water directly but are attracted by the greener plants found in such areas.

Rupert, Minidoka Co., Idaho, June 18, Between Malta and Sublett, that is in Roth River valley proper, there is an area, thousands of acres in extent in which only cacti and a very dwarfed Artiples is growing. I hunted through this area for Citellus mollis but failed to find any. There were numerous old burrows and mounds, however, indicating their presence there at one time. I drove on across the flat toward Malow Creek south of Sublett and as the land increases in elevation the cacti decrease in numbers and Artemisia becomes dominant. I found no C. mollis until I reached the old wash of Malow Creek where it leaves the mountains. Here there were a few living in a sandy clay soil that was like adobe in consistency. These squirrels seem to prefer such type of soil and I believe so because the soil packs easily and is easily dug and manipulated. Yesterday I drove to Bridge, a wide place in the road about

Again my impression that Oregonus and armatus occupy the sametypes of habitat seemed to be demonstrated. The armatus were found around a deserted barn, its corral and a pile of wood. oregonus were found in clumps of "Wild Rye", yet each I believe were competitors for the available food source. Q. mollis were found in that peculiar day like soil again and seemed to prefer open places for their burrows. though several burrows were seen at the base of Lithos Atriplex and Artemisia bushes. There is no competition between mollis and the other two squirrels so far as I could see. This P.M. I drove from Elba to Superb via Malta and Idahoome about 6 mi.

Sario 1935 Rupert, Minidoka Co., Idaho, June 18. 411 Sections I found a large colony of C. mollis and collected about a dozen of them - including several old ones These I believe are different from C. leurodow but are certainly very closely related to it. In the old ?'s the sides near the shoulders and an area encircling the sheath for the penis are cinnamon buff in color. I don't remember seeing this on leurodow. This colony was in the typical clay-like soil, preferring slopes and the sides of gullies to burrow into. It was about 6 P.M. when I was there and the old squirrels were sunning themselves at the mouths of their burrows. I found it most convenient to drive in the car over the area and pick off the old ones from the car. No. 7's shot in the 410 were excellent and usually knocked them so hard they could not get into the burrow. All the old ones are very fat and broad.

Perhaps the strain of raising a family prevents them from fattening up so fast and may also retard the molt -- a factor the [illegible]s do not have to contend with. The winter pelage, those coats in which the old fat males are now found, is long and silky and it from this, I believe, that the name "mollio" was taken. The summer -- spring at least -- pelage is short. I do not believe these squirrels mature in one year -- an idea I hold concerning Marmots -- because I have taken old ones, then found both very young and also middle sized ones at the same place and same time. This was the case at the area 10 mi. east of Seals. The squirrels were preparing nests for hibernation out of shredded bark of Artemisia, in two cases at least. The whole area here for several tousand acres is covered with a rank growth of June Grass (Bromus p.) which is utilized as food by these squirrels. Cheek pouches contained seed of the [illegible].

The only thing of interest was the finding of Citellus mollis at Strevell. This was a sight record only. June 17 was spent in packing specimens and getting ready to go out again. I left Rupert June 18 and drove to Raft River, about two miles down (south) from Snake River and hunted and trapped for gophers until about 5:00 P. M., and then drove on to Bonanza Bar — a camp on the south side of Snake River about 19 miles South west of American Falls — where I camped for the night. Raft River is merely a stream — at this point about 8' across — that flows through a broad valley which extends in a north south direction. Along the stream wild roses and willows are the dominant shrubs. A few plants cottonwoods are also found, but these are usually in the vicinity of dwellings.

These gophers are of the quadratus type and were found in damp- not wet - clay-loam soil along the river. The whole valley in this area is of that peculiar loose type of soil. Back from the river - outside the irrigated areas - Artemisia and Atriplex were common. Both Citellus mollis and C. oregonne were taken here. The former was most abundant at the margins of the farm where they met the rolling hills. There they were to be found burrowing along the fence, a post being a favorite spot by which to dig. Others were in the more open places where Artemisia and Atriplex were growing. C. oregonne was found along the river, burrowing into cut banks and also in the hay fields where they chose the higher drier parts. There none no

Between [illegible] River and Bonanza Bar there is a considerable area that was once dry farmed, but which has now been deserted. The land is beginning to revert to its former sage covering, but at present is densely covered with June grass. Here is the ideal place to find C. mollis. I noted them constantly up to within a mile of Bonanza Bar, which, being an irrigated area along the river, offers a habitat favorable for C. oreganus and C. armatus. Only the latter was found, and thus it appears that the area from Alliow to [illegible] River is a zone of overlap for these two species of Citellus. At [illegible] River I saw the following birds - Long-tailed Chickadee, Western and Eastern King birds, Black-billed Magpie, Harmed Owl, Marsh Hawk, Flicker, Yellow Warbler, Wex. Yellow-throat, Souter, Horned Lark Sage Thrasher, Pacific Nighthawk, Bank and Barn Swallows, Brewer and Red-wing black- birds, Black-headed Grosbeak.

At Bonanza Bar I made two sets for pocket gophers in the cultivated area and also two sets for Muskrat in a small creek which forms a sort of slough emptying into Snake River. The next morning I had two gophers and two muskrats; one of the latter was a young one and it was discarded. The morning of the 19th I put up specimens until almost 10 A.M. and then I collected by four traps and specimens and drove via American Falls to a ranch about 5 miles by road north west of American Falls on the east side of the river. I hunted on the way and on the east and south side of the river I saw many and collected four C. armatus. They are invariably found near water and prove the worst pests the farmer has to contend with when they are numerous. I arrived at the above ranch about 12:30 and inquired about squirrels and pocket gophers.

Got two 2. townsendie after waiting until about 6: P.M to look at my traps. Did not reset. According to this rancher a few years ago there were very few gophers in his fields, but since the formation of the American Falls Reservoir they have been a serious pest and at the present time the canal company is offering a 10c bounty on them. He attributes their presence there now to their being forced out of the river bottom by the rising water, thus forcing them into the irrigated areas. Here again we find Thomomy townsendie on both sides of the river - here and in the Nampa area, but between these two widely removed areas they are supplanted by the smaller quadrates on the south, and frescua on the north side of the river.

Kaufman, Clark Co., Idaho. June 27, On June 20, in the A.M. I made up skins until about 11:00, at which time I began hunting for Marmots in a rocky outcropping on the shore of the American Falls Reservoir about 4 mi. W E of American Falls. They were plentiful and were doing considerable damage to a crop of wheat which was nearby. They had sheared off a strip about 75 ft. wide along the edge bordering on the reservoir. Marmots do not reach maturity, that is full size the first - nor the second year - I believe. In this colony young of the year, many that were sexually mature, I believe, but only about 2/3 the size of the largest ones. I collected 3 - 1 old ♀ and two about 2/3 grown. The latter were discarded. The color of these small ones was identical with that of the one collected. In this same rocky situation I saw one Sylvilagus nuttallii; also a weasel. The latter was collected. It was first seen emerging from a crevice in the rocks, and catching sight of me it immediately retreated

Kaufman, Clark Co., Idaho. June 27. I "squeaked" on the back of my hand and it exposed its head and shoulders to look at me. Its .2 shot in the 4/0 was used to collect it. About noon I left this camp and turned west off the main road to hunt in a dry farm area for Citellus mollis. About 1/2 mile from where I had camped I collected the first one. It had a burrow in the hard volcanic ash soil (loess - and clay loam I have also termed this soil) in an open area near the road. I drove west for 14 miles, that is to the lava beds, and saw numerous burrows along the fences - a favorite habitat in cultivated areas - but only two squirrels, one of which I collected at a place about 20 mi. NW of American Falls. CCC boys have been poisoning squirrels extensively in this area and this doubtless account for their scarcity. After I reached the lava beds, I retraced my path a mile and turned north driving for approximately 10 miles in this direction through a dry farm area - many ranches were deserted. It was not until I

W B Savio 1935. Kaufman, Clark Co, Idaho. June 27 was about 16 miles NW of American Falls that I found a good colony and I collected several. These squirrels remind me very much of C. idahoensis in actions and especially in the 'dee dee dee dee' type of call. They certainly are different from those on the south side of the Snake River, and I believe their affinities are with idahoensis. I turned east again and drove into Aberdeen and from there followed the main highway to Pingree, a small village about 19 miles by highway from Blackfoot, on the west side of the river. About 5 miles W of Aberdeen I found a colony of about a dozen pairs of Long-billed Curlews. They were in an area of mixed Artemisia and June grass, the latter predominating, and about two miles from the nearest water. Two were collected, one saved as a skin, the other as a skeleton. I ate the meat of one and it proved quite delicious even though the flesh is dark and coarse. About 2 mis SW of Aberdeen I collected a garter Snake on a canal

I reached there about 6:00 P.M. and hunted until 7:30, collecting several, five of which I saved. June 21 was spent in making up skins and moving camp to 3 mi. E of Wapello in Bingham Co. This town is about 10 mi. N of Blackfoot. No specimens collected. The squirrels at Pingree - Citellus mollis - were living in this same whitish volcanic ash type of soil and most of them were on little hills - had their burrows there and foraged in the meadow. A few were living in the meadow proper, but not over a dozen were seen entering burrows there. The old ones are much wilder than the young and it requires a great deal of stalking or waiting to get them. 3 1/2 mi. E of Wapello the soil is very sandy in most parts, but an occasional area of volcanic ash may be found.

I camped for the night at the Government Canal and on the morning of the 22nd drove up the canal about a mile to a ranch house and hunted for squirrels. They were all C. armatus and were to be found in the vicinity of water, preferring the canal banks or some other embankment in which to burrow. The rancher told me they were a serious menace to the canal banks and had to be kept strictly under control or they would cause breaks in the canal. I saw two C. mollis along this canal in the same peculiar volcanic ash type of soil; one was collected. I shot the other one but it got into the burrow before I could get it. I spent about 4 hours in making up skins and then drove to Blackfoot and camped about 3 miles south of town and set 4 traps in the sandy area around camp in hopes of getting topotypes of Onychomys. The area in which I set was covered with Atriplex, Rabbit Brush and wild sun flowers.

It is of interest to note that the Arcs of 1889 when Bailey was collecting in this area was about 4 miles down the river from its present site. The town was moved when the Railroad was extended from Blackfoot to Mackay. Pioneer is 17 miles in a direct line S E of Arcs, and since Bailey and Dutcher collected 15 mi.

I believe this squirrel has reached there by migration thru the Bitterroot Mountains and thus into the Big Lost River Mts. and thence down the river to Arco. I talked with the local "squirrel" man and he informed me that C. arnott extended its range up the valley as far as Mackay and perhaps farther). From there on north, C. columbianus was the dominant squirrel. I asked him about C. mollis and was told there were none to be found in the country. I spent the greater part of the afternoon in driving about looking for C. mollis and found a small colony along the railroad tracks about 31 mi. SE of Arco. They, again, were in that loose type of soil. I succeeded in taking five, only one of which was an adult.

At the evening - I had hunted from about 3:00 - 7:30 P.M. - I drove to Pioneer, retracing my path on the highway as far as where it crosses the old river bed, and then turning SW and following the south bank of the now dry bed to the railroad. Along the course of the bed are several old cottonwood trees, many of which are now dead from lack of water. The whole area is covered with a mixture of short Artflex and Artemisia. The soil is very gravelly and from indications it would require a considerable amount of water to grow crops. It is this type of soil, I believe, that made it possible for the river to 'sink' into the ground. There is also a considerable amount of lava in the form of outcroppings and drift. Sand is found in some areas. I arrived at Pioneer just before dark - about 8:30 - and set out 20.

The squirrels were living in a high portion of a field that bordered on the right-of-way of the R.R. tracks. The field was too high to water easily and was not under cultivation, being overgrown with "Russian Thistle." This plant was used extensively by these squirrels both for cover and as food. In an old ditch that had blown full of these weeds—"fleer," called tumble weeds locally—there were dozens of burrows, these running parallel with the ditch bank usually for about 10 or more feet and having several entrances ranged along in tandem fashion. The squirrels were also burrowing into the R.R. bed and occasionally they had burrowed into flat ground. This last was the exception. Raised ground or ditch banks were favored.

the area, especially in the vicinity of Berenice. Little Lost River is hardly more than a creek now for practically all of the water is diverted to the fields, alfalfa being the chief crop. No water reaches the "sinks" - a condition like that of Big Lost River. The Lemhi mountains - to the NE - and the Lost River Mountains - between Big and Little Lost rivers - rise abruptly and are barrow of trees, save in occasional favored slopes near the crest. The slopes are exceedingly steep and rocky and deeply eroded. At the base of the mountains wherever a canyon enters the main valley alluvial fans are prominent - these areas are termed "benches" by the local residents. Mr. Peterson told me that a government trapper who operated a string of traps from Twin Falls to Howe during the winter of 1934-35, had averaged about 200 coyotes per month. He used poison almost exclusively.

W.B.Davis 1935 Kaufman, Clark Co., Idaho, June 27. June 26 - at Berenice, Butte Co., Idaho. I spent most of the forenoon in making up the Citellus skine I got on the 25th near Arco. In the afternoon - about 3:00 P. M. I hunted for C. mollis. They were very abundant along the right of way between Peterson's ranch and the Lesmhi mountains. Mr. Peterson had wheat and alfalfa growing on his ranch and where these fields bordered the road the destruction wrought by these squirrels was quite evident. A strip about 75 ft. wide was heavily grazed. Mr. Petersen said the wheat suffered most for the squirrel had a mania for pulling down the stalks and nipping off the heads of the plants. The squirrels were living in burrows excavated for the most part in a deserted tract of land across the road from the Peterson ranch. This place was overgrown by "Russian Thistle", which, during previous years, had matured, dried, and been blown by the wind until they were caught by some

Here their burrows were dug and concealed from view. As I walked down the road hundred of squirrels were seen crossing the road from the green fields to their burrows beneath the tangle of dried Russian Thistle. They were exceedingly every while in either the field or the road, but once they were in the tangle their whistles could be heard in all directions. I succeeded in shooting 10 of them, including some old &'s and ?'s. Most of those seen, however, were young of the year. The old ones were exceedingly fat, especially the &'s and I believe they are the first to go into hibernation. These squirrels are quite adept in climbing. Many were seen perched on portions of limbs that had been left on the juniper fence

posts and two young were observed climbing up a mesh fence. I doubt that they are able to climb like a Sciurus, for instance). Only the young were observed climbing. The old ones were much more wary than the younger generation and usually entered their burrows before I got within shooting range. My usual method was to wait until they reappeared. From examination here in the field, I can see no differences between the squirrels taken at Taber, Pioneer, Arco and here. I left Berenice about 5:30 P.M. and drove here - a distance of about 40 miles. This necessitates going around the spur of the Lemhi Mts. and thus getting into Bird Creek Valley. Between Berenice and the point of the mountain - a distance of about 10 miles - there is considerable sand. The chief shrub in this immediate area was Atriplex. Sage - Artemisia - was again encountered after the point had been passed. I arrived here about 8:30. The roads were very rough

and run in all directions. None of them are marked. One picks a road that runs in the general direction he wishes to go. The rise in Birch Creek Valley is very gradual and after the area of the sinks is left, the soil becomes exceedingly gravelly, such as that found in the vicinity where the Blackfoot-Arco highway crosses Big Lost River. Kauffman, Clark Co., Idaho. June 27. Kauffman - once a post office - is now nothing more than a small store on the bank of Birch Creek, about three miles down stream from "the narrows" and about 13 miles S of Nicholia). Mail for this area is sent either to Winsper or to Reno. Mr. Baer, proprietor of the store, gets his mail via Winsper. Birch Creek, like both Lost Rivers, is diverted entirely to the fields, the last water going to the Reno Ranch, about 18 miles down the creek from here. At Kauffman the creek is about 15 ft. wide and 3 ft. deep. H.

W.B. Davis 1935 Kaufman, Clark Co., June 27. 436 is heavily stocked with trout, but the entire creek above Kaufman is now closed. Even so many large catches are reported. Along the creek the chief vegetation is the birch, accompanied by alder, aspen, and lower down, willow. Some wild roses were also present. As I mentioned before, the soil is very gravelly, and as a result very little land is suited to cultivation. The first ranch on the creek is about 3 miles below Kaufman, save for the Reno Ranch which is not in the valley proper, and these are found only in the vicinity of the creek. Water seeps into the ground very rapidly and according to Mr. Bace there is no sub irrigation at all. Thus, the greater part of the valley is typical desert and supports a growth of dwarfed Artemisia and grass. In the spring, grass is plentiful, especially on the "benches" and as a result grazing is the chief occupation in the valley. I was told by a Mr. Williams that years ago the stand of grass supported

The creek is near the mountains to the east and these rise abruptly from the valley, presenting deeply eroded canyons and supporting very few trees save near the creek in sheltered areas. The Lemhi mountains are quite high here and at this writing still have some snow banks left. Pass Creek enters Birch Creek about a mile up stream). This afternoon, after I had put up the skins I got yesterday, I drove about 2 miles up stream and hunted for Citellus artemisiae, and Thomomys idahensis as this is the type locality for both these. I succeeded in locating the workings of gophers along a ditch bank, and also in an unused, dry, rocky portion of a field. I made nine sets - all my

The burrows are quite small in circumference diameter also) in most cases and I had some difficulty in getting the Muscle traps set. In almost every case the burrows were less than 6" below the surface. I saw no C. artemisiae, but did see and take two C. elegans. I found them at Kaufman too, but no further down stream. These squirrels had burrows in a dry area that supported scant vegetation near an alfalfa field, they foraged. The whistle of these squirrels is quite similar to that of C. oreagana. I heard several Marmots in the rocky outcroppings near a ranch 2 mi up the creek from Kaufman. The owner of the ranch said they had been doing consider- able damage to his hay crop and that he had been trying to poison them with strychnine on fresh alfalfa with little success. I believe they are mosophora. I set out no mouse nor set traps. Muskrats are reported as being present in the creek.

O.B. Davis 1935 439 Carfman, Clark Co., Idaho. June 7. About 6:00 P.M. I draw down the creek about 8 miles in search of C. artemisiae and succeeded in taking only one. Working of Thommys were plentiful in this dry area where the Artemisias was only about 12" high at the mark. I investigated several burrows and found they were less than 4" - usually about 2" beneath the surface. I found that the roots of the Artemisiae were being utilized for food. The ground squirrels were either very scarce or had gone into their burrows for the day as I saw only the one I got. There is none of that volcanic ash type of soil in this area that I have been able to locate. Everywhere it is gravel. I compared this young squirrel with others I took at Berenice and can see no appreciable difference. The measurements given by Merriam (1891:38) for U.S.N.M. no. 23489 - the type of C. artemisiae are 188-43-31. The one I took, which, from all appearances is a young of the year, is 186-43-31. Evidently Merriam's type is also young,

Took up the traps and made up the skins). In the afternoon I drove down the Creek about 2 mi. and made 9 more sets in a dry area at the edge of an alfalfa field. These burrows were from 4 to 8 inches below the surface. I could hear the faint whistle of C. artemisiae, so spent the greater part of the afternoon in hunting for them. These animals are exceedingly wary and blend in so well with the terrain that it is almost impossible to see them unless they are moving. I succeeded in taking 5 more specimens, all of which I believe are young of the year. None of them were very fat. They were found for the most part on the banks of a canal that is no longer in use, and almost invariably

It seems that they prefer some sort of elevated ground to burrow into, although I found one burrow that was next, in the road. I could observe no differences in actions of these squirrels from those taken at Taber, Arco and Berenice, and certainly the color can be matched with specimens from each of the above localities. I believe they are all the same race, for certainly there is no barrier to separate them. Admittedly, the habitat is different, I looked at my gopher traps this evening. No luck. Two traps were filled with dirt so I reset them. Found the decayed body of a badger along the canal bank where I was hunting. Saved skull only. Also found the rutler of a Mule Deer near the base of the mts, about 1/2 mi. E of the creek,

Left Birch Creek about 9:30 a.m. and drove to American Falls via Dubois, Idaho Falls and Pocatello. About 10 mi. W of Winifer, Clark Co., I saw a flock of sage grouse, the two parents and 12 young about half grown, At Small I noticed several Citillus elegans. These, like armatus and oregonus prefer the areas in the vicinity of water and cultivated areas, none was collected because last year I took a few there). I looked for C. mollis along the route but failed to find any save at a locality about 5 mi. E of Terreton, Jefferson Co., here a small colony was located in a sandy clay ridge along the edge of a wheat field. They were extremely wary, I saw two of them and shot at one, but it got down its burrow before I could get it, I dug down about 2 ft. and failed to find it. They looked like the dark phase of the young found at Birch Creek, I hunted here about an hour and gave up because of a dust storm. Dust was so thick that I had difficulty in seeing the road and I was forced to stop twice).

Made up the skins I took yesterday and broke camp about 1:30 and drove to Rupert, Minidoka Co. June 30 to July 9. No collecting done. Visited with friends and celebrated the 4th in style. First 4th I have celebrated in 3 years. Wickel Ranch, Elba, Cassia Co., Idaho, July 9. Today I was pitching hay in the field and as I lifted a shock a single male Citellus oregonus dashed madly across the field. I dropped the load of hay and gave chase, pitchfork in hand. After about a two minute's chase I succeeded in catching it. The agility and speed these squirrels have is amazing. I left Elba about 8:30 p.m., and drove to the desert about 6 miles W of Burley where I pulled off the road and slept for the night.

I then drove to Twin Falls, hunting on the way. About 15 mi. W of Burley I found a colony, but from all indications most of the members were aestivating. I saw two individuals and several burrows that had been used this summer, but which now had spider webs across the entrance). None was taken here although I hunted for fully 30 min. About 13 mi. E of Twin Falls, at the edge of the irrigated area I found an active colony and hunted for about an hour, taking 28 and 14. They were numerous here, but so wary that hunting was a task. The colony was located in an area about 100 yds long and 30 yds wide between a canal and the highway. The principal cover was Artemisia tridentata and June Grass. The latter was mature and dry. In the grassy areas numerous well beaten trails were in evidence, crossing and recrossing each other. These led from burrow to burrow and also from burrow

Shoshone Falls, Snake River, Twin Falls Co., Idaho. July 10. To forage grounds. Many of the burrows were under willow slashings along the canal bank. I saw several young which I could have taken, as I walked back and forth over this area, their low, yet high pitched, whistles could be heard in all directions. This whistle I believe is the alarm cry - warning to others, - and it is very deceptive. I tried the idea of trying to locate the squirrels by their whistles, but failed. I believe they give them while in the burrow, yet not back so far that they can't see out. I know this is the case with one I saw giving the whistle at Bridge, Cassia Co. I saw one young with its mouth filled to overflowing with shredded bark of the sage brush sitting up at the burrow giving the low whistle. The cargo seemed not to impede the power of whistling at all. This bark was doubtless for nest material. Arove on to Twin Falls, and then drove to a ranch about 1½ mi. S of here where I trapped for gophers without success. Had 5 sets out from 12:30 to 5:00 p.m. Two were filled with earth, the others un-touched. The burrows were small, as I

Oregon Ground Squirrels were reported as having been present at this ranch a week previously, but I saw none in the 1/2 hour I hunted for them. Perhaps they have aestivated. I noticed at Elba that very few - and in some cases no - squirrels were to be found in areas where I had found them abundant a month previously. Arore down here about 6:00 p.m. and set out 45 mouse traps - half on each side of the river - amongst the rocks at the bottom of the basalt cliffs that border the river. The river here is about 200 yards across and is confined between cliffs about 300 or 400 feet high. Very little water is going over the falls. Along the bank of the river are willows and wild roses; back farther a few Artemisias are present, and June Grass is common. Saw hundreds of Cliff Swallows nesting on the cliffs overhanging the water and heard Chats, Song Sparrows, Yellow Warblers and Yellow-throats in the willows. Saw one Junager (western) in the canyon.

The soil is extremely dry and stony and the grass, save in the boggy areas along the stream is well grazed. Sheep have passed here recently. The dominant herb is a species of Pentatomen which is found everywhere save under the forest cover. I set out 5 gopher sets and went hunting before I established camp.

I took from them 2 ad & with well developed mammae - evidently suckling young. The gophers are burrowing about 2 to 3 in. below the surface in the dry stony ground - preferring the open forest areas.

A possible explanation is that most of the dirt is packed into the old winter burrows. The amount of earth in some of the cores is astonishing, and this having been removed from burrows used in the winter would leave a considerable space in which to pack dirt excavated in the new used burrows. I set in a burrow found in a dry island in the bog near the creek and caught one ?. There were no workings in the surrounding wetter area. Did the animal get there during the winter thru the snow, or did it move in the open across this bog? I believe the former idea answers the question better. I hunted in the p.m. for about an hour and shot 1 C allaspermosphiles at the edge of a small clump of fire. It ran to its burrow under a rock on the open hillside and died at the entrance. I took a ?

I shot it and found that it was completely blind in one eye and nearly so in the other. About 30 large Ornithodorus (ticks) were attached around the eyes and chin. The lids of one eye were sealed with dried puss and when I cut into the cavity about a teaspoon full of puss exuded. The cornea of the eye was opaque, and had the animal gotten rid of the ticks I doubt that that eye would ever have been functional again. The lids of the other eye were almost swollen shut. I picked off all the Ornithodorus, each about the size of a shoe button and placed them in spirit. I also found several wood ticks in the fur, four of which were saved. I didn't relish the idea of skinning the animal so saved the skull only and used tweezers in handling it. There were no ticks attached to the ears as I have found them on Sylvilagus and Lepus californicus. I shot a Vermithrush in a thicket of Lodge Poles near a little swamp.

W.B. Davis 1935. Mammals examined from Idaho in the Chas. R. Conner Mus, Pullman, Wash. 473, Remarks about Peromyscus artemisiae. There is considerable variation in color, ranging from light - nearly gambelii type - Nos 346 + 95 - to very dark # 335. These extremes are extremes of summer and winter coat color. However, when summer taken animals are compared, # 95 + 346 are still much lighter; the sides are more fulvous; the mid dorsal area is not so dark. All the mice have very distinctly bicolored tails, nearly black dorsally, whitish below. In summer, the eye ring is not so dark and conspicuous. All the specimens are very much lighter than sonoricensis. skulls of Peromyscus m. artemisiae.

This specimen has been identified by R.M. Anderson as Z. p. oregonus. I have compared the skin with typical oregonus and find the dorsal coloration not so dark, as it compares favorably with Z. p. idahoensis and should, perhaps, be considered as such. There is no skull. However, on geographic grounds it is here assigned to rootenayensis

W[illegible] Davis 1935. 474 Berkeley, Alameda Co., Calif. Dec. 9, Ward Russell brought into the museum today two adult Horned Owls that were collected. On these I found several large parasitic flies which I collected and took over to the Entomology department and gave to Professor Verms, [illegible] tentatively identified them as Family Hippoboscidae, Genus Offertia, species americana. They were well gorged; wings longer than abdomen; had parasitic ticks or mites attached to the abdomen; flattish in build and very peculiar in action. They moved sideways quite as readily as they did forward. These are to be experimented with to see if they can transmit malaria to quail. Dec. 20. I picked up a Ruby-Crowned Kinglet yesterday morning at the corner of Fulton and [illegible]. It was dead, but in good condition as regards plumage. See field no 1584. The stomach was about half full of insect and vegetable remains. No cause of death was found, i.e. no apparent injuries.

W.B. Davis 1935 475 Rupert, Minidoka Co., Idaho. Dec. 24. Arrived in Rupert Sunday morning, Dec. 22, after driving straight through from Berkeley - a 21 hour trip). (Dec. 22) Sunday afternoon, Howard Swining and I took a walk along the canal west and north of town, were out one hour and collected two birds, a Junco and a Sharp Shinned Hawk. Saw the following birds in addition. 1. English Sparrow - Hundreds 2. Flicker - 6 3. Long Sparrow - 3 4. Junco - 1 flock of about 50 5. Rocky Mt Nuttatch - 1 6. Pinon Jay - 2 7. Horned Lark - flock of about 50 Weather is clear and cold. No snow, but lots of ice. The river is frozen over in many places) and Lake Walcott is entirely covered with ice from 2 in to 12" thick. In the P. M. - about 4-5:30. Howard, Ray Ennis and I drove to the Minidoka dam to watch skaters. The ice was ideal. We drove along the river and were fortunate enough to see several hundred water fowl.

W.B. Davis 1935 476 Rupert, Minidoka Co., Idaho, Dec. 24, The following birds were seen near the dam, Dec. 22. 1. Pintail - about a dozen identified 2. Scrape sp? - hundred or more. 3. Mallard - several. 4. American Merganser - several. 5. Black-billed Magpie - 23. Yesterday I drove Howard to Minidoka where he boarded the train enroute to Hailey where he will collect. On the way to Minidoka we saw one American Roughleg and several Plover. They were picking at the bodies of rabbits which had been run over on the highway. While at Minidoka I met Mr. Nephi Duncan, a section hand on the O.L., who spends his spare time trapping. He had 13 coyote skins taken in November, all in the vicinity of 12 mi. NE Minidoka I purchased two skins, ???. for $7.00 These two skins represent both the dark and the light color phase. Most of the 13 skins examined were comparable in color with my darker one. I retrieved seven

Mr. Duncan told me that Bobcats were quite common in the lava beds N.E. of Minidoka and that last year he took twelve of them in his spare time. He promised to try to get me 3 or 4 and would tax them and save both skins and skulls. He appeared to be interested in my work and perhaps is worth keeping in touch with. While at Minidoka I saw one small flock of Horned Larks and several hundred English Sparrows, Collected 2 of the latter. On the way back I collected to American Roughlegs along the road about 3 mi. S.E. of Minidoka. I put up a ? last night. The crop and stomach were empty. I shot at a Raven, but didn't bag it. On the way back I stopped at the ranch of Mr. W. A.

His method is a "secret", but he did say that he never sets his traps near the den because the female, is less inclined to wandering than the male, is then likely to be caught. He showed me two beautiful male skins, well prepared. I was able to retrieve a complete skeleton of one that was trapped about ten days ago. The other body couldn't be located. Mr. Curtis refused to sell me either skins because he was planning to enter them in a Montgomery Wards "Better-prepared- skins" contest. He said, however, that he would be willing to try to get some later in the season. He will be worth keeping in touch with. Mr. Curtis is a collector of arrow heads, and he took up about an hour of my time showing me his collection. Mr. Curtis reported that minks were not common in the rivers. He estimated the population on his

He said that in 12 years of trapping on the river here that he had never caught nor seen any sign of River Otter. He believes that Shoshone Falls acts as a barrier to the population lower down stream. Today, Dec. 24, was another clear, cold day. I visited the Carlson Fur Co. this A.M. and asked them about furs and trappers. They buy furs occasionally. Mrs. Carlson told me that a trapper on Goose Creek south of Oakley had a couple of Cow skins that he had taken in that area. His name is Ned Emery, address at Oakley, Idaho. I plan to visit him this week if the weather is favorable. I drove out to the ranch of Mr. David Krause, about 2 mi. east of Heyburn. He is trapping muskrat and other smaller fur bearers. To date he has taken about 300 muskrat skins, 2 striped skunk, and 1 weasel. Mr. Krause was not at home, but I

I measured and saved the skulls of 12 muskrates and one single large skull was collected which had been removed from the body. The bodies had been cleaned pretty well by the chickens so they could not be sexed. Drove to Albion and looked up Archie Lannabury. He was not at home, but I saw three coons, one coyote and one badger skins that he had taken south of Albion a few miles. Tried to see Carl Farley, but he was not at home. Drove then to Hawells Canyon to look up Bob Lannabury who is trapping there. He was not home. Saw the remains of a porcupine at his cabin and stumbled onto a set of his baited with a male Spilogale. I measured the body and cut off the head with the skin of same. While up here saw very few birds. Collected 2 Longtailed Chickadee, 1 Mt. Chickadee + 1 Leaf colored Bush Tit.

(W.B.) Davis 1935. Rupert, Minidoka Co., Idaho, Dec. 25. Drove to a drain ditch two miles S.E. of Rupert. Spent from 1-4 P.M. in the field. Was clear and cold with a slight west wind. No snow, but ice on the ditches. Saw the following birds): 1. Sharp- skinned Hawk, 2. Junco sp. Flock of about 30; 3. Song Sparrow, 4. Willow Goldfinch - two, 5. English Sparrow, Common around ranch houses. I took one each of the Song Sparrow, Junco and Goldfinch. I looked for muskrats along the drain, but saw no sign in the mile that I walked. Dec. 26. Drove to Oakley, then across the mountain to Elba and back to Rupert via Alden. The day was clear and cold. Still no snow. On the way to Oakley I collected two Roughlegs; one I shot, and the other I picked up, slightly injured, of the highway. It had evidently been eating a dead rabbit and had been hit by a car. I saw several American Cranes a few miles north of Oakley.

W.B.Davis 1935 Rupert, Minidoka Co., Idaho, Dec. 26, At Oakley I visited Mr. Clifford Fairchild only to find that he was not trapping this year. However, I did meet Mr. Ned Emery who has been trapping in the Goose Creek country south of Oakley. He showed me his fur catch which consisted of 103 coyote skins, I think (taken about 15 mi. S of Albion, 6 muskrat, 1 badger, 2 raccoons, 8 Bobcats). I purchased two cats, two coons and one badger skin. Mr. Emery promised to send me the skulls of the two coons. He also promised to send several skulls, eyes, & various fur bearers. Mr. Emery works for a group of sheep men in cooperation with the B.S. and is opposed to the principle of poisoning coyotes. He, is also opposed to the $1 bounty on eagles. His reasons are based on sound biological principles. The two raccoons were trapped in coyote sets fully 1/4 miles from Goose Creek -- in the sage. Mr. Emery reported that he has seen coons on several occasions along Goose Creek,

The two cat skins, nos. 1625-1626 are mother and kitten, according to Mr. Emerg. He reports that cats are common along the "rim rocks" — basaltic outcroppings in the mountains thereabouts. On the way from Oakley to Elba I picked up a Horned Owl that had been shot two weeks previously and thrown along the side of the road. It was frozen and still in good condition. Along side the owl was an American Roughleg, pretty well damaged, that had been killed by the same rancher. The stomach of the owl contained Mags. I had some difficulty in crossing the summit between Oakley and Elba. There was considerable snow and mud on the west slope, and deep snow on the east side. Stopped at Elba for a few minutes and visited my uncle, Melvin Wickel. Drove thence to Albion and stopped at the ranch of Andrew Peterson,

These were taken in the near vicinity and the skins were well prepared, with fat attached. These were the only skins Mr. Peterson had taken this season. He promised to get skulls for me -- skulls for these skins). The skins are numbered 1, 2, 3 and the skulls, when gotten, will correspond to these numbers). No. 1630 is # 3.

He had caught two minks and several muskrats but had sold them. Said he would be willing to save the bodies of any other minks he gets and send them. Left shipping tags. He told me that he usually traps in the Tetow area in (Wyoming for Martens. He said that in Wyoming the practice of registering trap lines has been in vogue for several years. Last year he said he took over 50 martens for which he averages $10 each. He gave me the name of his brother-in-law Bill Kuebli, Clayton, Idaho who is trapping in the Sawtooth area near Stanley. He reported that martens were more numerous this year than they have been for years. Mr. Peterson Christensen said that he saw definite evidence of River Otter about a month ago along the river. I have no basis by which to judge his integrity, but he seems to be trustworthy.

W.B. Davis 1935, Superh, Minidoka Co., Idaho, Dec. 28 I stopped at the Jackson Bridge about 3 mi. SE of Acquia and hunted on the islands in the River. Near the bridge I found a buteonid hawk that was pretty well demolished. However, I picked it up and saved the leg and foot, wing and skull. On the island I saw evidence of Cottontail rabbits; saw Sage Grouse, Black-billed Magpie, Song Sparrows, and Juncos. On the river I identified (American Merganser), Mallard, and Coot; I collected two Juncos from a flock of about 50. These appear to be [illegible] distinct species). I stopped at my uncle's ranch 2 mi. E. of Acquia for an hour and visited with him. He told me he had two coyote skulls taken in Nevada which he would send. He strongly maintains there are two species of coyote in Nevada - one with a white tip to the tail, the other with a black tip. The white-tipped is supposed to be the larger. While at his ranch I saw a large flock of Brewer's Blackbirds feeding with a herd of cattle. This bird usually is found where stock are fed out-of-doors

W.B. Davis 1935. Rupert, Minidoka Co., Idaho, Dec. 28, On my way back to Rupert I stopped along the highway at Acequia and set 12 mouse traps in an area in which I have trapped Dipodomys. Tracks which I think were made by this animal were found in the fresh snow. The traps were all set near burrow openings and placed about 50 feet apart. On the way from Acequia to Rupert I saw two Marsh Hawks. Dec. 29. This morning I drove to Acequia to look at my traps. I had caught only six Peromyscus maniculatus. Those that were killed outright by the traps were frozen stiff. One individual that was caught by the hind leg and tail was still alive and appeared quite active. These specimens are all much darker than summer taken specimens from this same area. Even so, they are not as dark as summer taken specimens of P. m. artemisiae. These specimens are nos. 1636-41. This P. M. more snow fell, but it doesn't last very long outside the town.

W.B. Davis 1935, Elba, Cassia Co., Idaho. Dec. 31 Yesterday I moved over here to my uncle's ranch - the Wickel Ranch - on Cassia Creek). There is about 8" of snow here on the level and in sheltered places drifts of two feet depth are not uncommon. This afternoon I took a hike down through the field, following Cassia Creek, and then veered south to the juniper clad slopes of the hills. The walking was rather difficult in places where the snow had drifted. Along the creek I saw a flock of juncos and several Song Sparrows. One of the latter was collected. Magpies and Red-shafted Flickers were frequently seen. In the juniper area the Black- tailed Jack Rabbit has made a maze of runways in the snow. In my instances one could see where these animals had been browsing on Artemisia tridentata and Juniperus scopulorum). Small branches of the latter had been broken from the tree and these had evidently been fed on while they were in the snow. I saw hundreds of Jack Rabbits during my four hours in the field.

W.B Davis 1935, Elba, Cassia Co., Idaho, Dec. 31, 4/92 Bird life in the junipers was more or less plentiful. I saw a couple of Ravens hovering on the uprending air currents near a butte and several Black billed Magpies were noted. These were extremely wary and could not be approached within gunshot range. I located two flocks of Gray Titmice. They were flying from one dense juniper to another uttering calls that remind me very much of the Chickadee. In fact I thought the birds were chickadees until I saw them. This is my first experience with this race of Titmice. Their actions were no different from the Plain Titmouse so far as I could determine. Their habitat, however, is different. These birds called only when I was close to them so after I had collected one bird and was preparing it for carrying, I often lost track of the flock for several minutes and had to explore for the birds. They appeared to be feeding on something on the bark of the trees for the most part and

Elba, Cassia Co., Idaho, Dec. 31, their hammering “woodpecker” antics could be heard on several occasions. a peculiar scolding note was given if a bird were approached too closely. at such times the crest was raised so it was prominently seen. Dr. Jayne Renagy of Rupert showed me a set of eggs of this species that he took at the Dewey Ranch on Marsh Creek about 8 miles east of Elba. This, I believe, is the northernmost breeding record of this species. It is the only breeding record I know of for Idaho. At the ranch I saw a covey of California Quail. The birds were unafraid for the most part, and fed around the haystacks. I frightened them and they flew to a thicket of willows and sage bushes, where the snow was drifted to a depth of about two feet and in places weighted down the bushes and formed a roof over cavities below. The quail secreted themselves in these cavities. The birds roost in the dense bare branches of the Lombardy Poplar that form a wind break for the house.

W.B. Davis 1936. Ella, Cassia Co., Idaho. Jan. 1. Today I went for a horseback ride with one of the ranchers. Our purpose was to see deer. We left the house about 11 A.M. and returned about 5 P.M. after having ridden about 15 miles. The day was ideal. We rode up Quaking Aspen Creek – tributary to Cassia Creek from the south in stormy weather – to the summit and then climbed to the top of a mountain where thickets of juniper and Mountain Mahogany were found. On the lee of this peak the snow was drifted to about four feet in depth. We saw three Mule deer, two male and a female. They appeared to be very large and I believe are typical of hemiones. They had been feeding on juniper, Mt. Mahogany and low shrubs which I did not identify. We came where they had been bedded down in the snow on the leeward side of a clump of junipers about 15 ft. high. On this trip we saw several tracks of deer, but these three were the only deer noted. We saw hundreds

W.B. Davis 1936 495 Ella, Cassia Co., Idaho. Jan. 1, of Black-tailed Jack Rabbits, I also saw the tracks of one coyote. A Mr. Green who is trapping this area told me he had caught only 21 coyotes this season. He reported that they were not common in this immediate area. He had none when I visited him. He had sold them for $3.50 each. This morning I looked for tracks of small mammals in the snow. Peromyscus maniculatus tracks were common in an area near the Wickel home where Artemisia and Sarcobatus are common. There was also a pile of large logs (12"-14" in diameter and 12'-20' long) near by. The tracks of the mice seemed to begin at this pile of logs, and emanate in all directions with the tracks returning to this same log pile. I followed one set of tracks. This animal travelled from brush to brush in a wandering fashion to a point about 100 feet from the log pile where the brush ended and a field began. The mouse then circled back and reached the log pile again. None of the other tracks led more than 100 feet

In the juniper area, however, I saw larger tracks made by an animal that progressed by hopping - - as evidence the feet being placed opposite each other), and there was a distinct tail mark). These I took to be tracks of [Sipuelomyp]). Along Quaking Aspen Creek where the water was not frozen over I flushed several Jack Snipes. The snow in this region was about 12" deep). Jan. 2. Today I left Elba and drove over the pass into Albion and thence to Rupert. The roads were in poor condition, on the Elba side of the pass there was snow to truck while on the Albion side I ran into rain and mud. Rained nearly all day. I stopped in Albion to see Raymond Wickel who had a Coyote skin that he had taken about the first of December in the hills south of Albion. The skin was from a large male and was dark in color. Paid him $4.00 for it, IKe promises the skull later.

W. B. Davis 1936. Belleuve, Blaine Co., Idaho, Jan. 3. This noon I left Rupert and drove to Bellevue via Paul, Hazeltow, Eden and Shoshone. There was considerable snow on the highway most of the distance), but the day was clear. Here at Bellevue the snow is about 20" deep save where it has drifted. When I arrived I learned that Jwining had left for Baker Creek, 12 mi. N of Petchum with Mr. A. W. Linderman, a trapper who has trapped in this general area since 1923. I learned that Jwining had taken Bohemian Warwings, Western Evening Grosbeaks, White-tailed Jack Rabbit and Great Horned Owl. Had also purchased a badger skin from Gene Glahn. About 12 mi. W of Rupert I saw two Horned Larks, one of which I collected. They were fairly common between Paul and Hazeltow. English Sparrows were common about each ranch house. About 5 miles south of Shoshone I saw a flock of about 50 Ravens near the highway. They were feeding in part on the jack rabbits that had been killed by passing automobiles.

W.H Davis 1936. Bellevue, Blaine Co., Idaho, Jan. 3. Between Shoshone and Bellevue I saw several small flocks of Horned Larks and at a point about 3 miles north of the Ice Caves I saw two Sage Hens. Jan. 4, I am staying at the Ennis home here in Bellevue. Mr. Warley Head, a sheep man who married one of the Ennis girls, gave me his opinions of the poisoning program of the B. S. He is absolutely opposed to this policy on the grounds that it is too costly and deprives trappers of money. He cited the instance that in one month two years ago a single trapper caught 150 coyotes during the month of November. In this same month the B.S. is supposed to have reported 180 coyotes killed in the entire state. Mr. Head believes in control of coyotes but by other means. He hadn't thought of the effect of poisoning coyotes in relation to the ground squirrel problem, but did maintain that many animals other than coyotes were destroyed. He is in favor of the new Taylor act and believes

W.B.Davis 1936. Bellevue, Blaine Co., Idaho, Jan. 17, this act is a God send to legitimate sheep men because it will prevent the great speculation in sheep that has taken place in this region in the past. Mr. Head maintains that the legitimate sheep men are not destroying the range, but rather those who speculate. Such persons buy huge numbers of sheep, pasture them on the public domain with no thought of preserving the range for the next year, but with the one thought of keeping the sheep only until they can be turned at a profit. I took a hike 10 A.M. to 2 P.M. along Wood River, beginning at Bellevue, and working north for about a mile. The snow was so deep that walking was difficult. The riparian growth here consists largely of Cottonwoods, some alders and an understory of rose bushes and other small shrubs. Black-capped Chickadees were encountered on two occasions. They were in flocks of perhaps 50 and were flitting singly and continuously from tree to tree, feeding from the bare branches. I collected two of them -- Nos. 1652-1653.

W.B.Navo 1936 Bellevue, Blaine Co., Idaho, Jan. 4. I flushed about a dozen Mallards from places in the river where the water was flowing fast enough to keep free of ice. Water Owls were fairly common along this same stretch of water. I heard the song given several times before I saw the birds and when I first heard the bird I was at a loss as to its identity. The birds were observed to be feeding in shallow swift flowing water, and when frightened they often flew under the overhanging shelf of ice where they were obscured from sight. I saw seven of them and managed to collect one. However, I killed two birds, one of which could not be retrieved. I saw two Rocky Mountain Creepers, one of which I collected. The birds were feeding from the bare trunks of the Cottonwoods. Other birds observed were Flicker, Black-billed Magpie, and Bohemian Waxwings. I attempted to collect a few of the latter last but failed. These birds are feeding on frozen apples still hanging to the trees and on the berries of the wild rose. About 500 were seen.

W.B. Davis 1936. Belle Vue, Blaine Co., Idaho. Jan. 4. Along the river I saw numbers of cotton wood trees that had either been felled by beaver, or partly cut down, in one instance a cottonwood tree about 20" in diameter had been attacked and deserted for the time being. This mammal is reported to be quite common in this locality. Jan. 5. Snowed about two inches last night. Today has been clear. Took another hike north of Bellevue along Wood River beginning at the power plant and then north about a mile and then south along the dry bed of the river. All the water at present is diverted to the power plant. In field from 10 - 4. The cottonwoods are in dense stands along the river bottoms and many of them are good sized trees. Many trees are dead. These growths constitute the main source of fuel for the inhabitants of this area. I saw perhaps a dozen magpies, 20 Mallards, 1 flock of about 30 Black- capped Chickadees, 3 Rocky Mountain Creepers, 1 Rocky Mt. Nairy (woodpecker),

These Waxwings) are formed into huge flocks that stay in this general area. They alight in the tops of the tallest trees except when they are feeding, and when in flight or perched they keep up a continuous chattering. They are very timid birds and appear to be highly strung. Usually a continuous stream of birds is kept in motion between the cottonwoods and the apple trees) in town) when the birds) are feeding. I collected several birds today: Song Sparrow, Creeper, Goldfinch, Chickadee, (Woodpecker) and (Water Ouzel. See nos. 1655- 1667. In a grave of Cottonwoods today I heard the chatter of a tree squirrel Sciurus h. richardeoni. I was unable to locate the animal because of the difficulty of getting around. I found the Chickadee and the three Creepers in the same flock today; The Woodpecker was hammering on a partially dead Cottonwood. Saw no mammals

W.B. Davis 1936. Bellevue, Blaine Co., Idaho. Jan. 6. Rode to Shoshone today with Mr. Warley Head and Kenneth Ennis. These two dropped me off there and they continued south to Jerome and picked me up about 6 P.M. This evening. The day was clear, but a strong east wind made it uncomfortable to remain out of doors for long. I collected near Shoshone along Little Wood River from 11 A.M. to about 3 P.M. Birds were scarce for the most part. I saw the following birds near Shoshone: Song Sparrow. These were in the thickets along the stream. They were feeding for the most part on the ground where the snow had been melted. Here they scratched much as does a Gambel Sparrow. Juncoes, one large flock of about 50 birds was seen. The birds kept in the willows, but did most of their feeding on the ground. Both Song Sparrows and juncoes were seen feeding side by side. Black-capped Chickadee - Three or four seen; Mountain Chickadee - 1 seen. Both these species were with the Juncoes and Song Sparrows. Black-billed Magpie Several noted; Red-shafted Flicker, six.

English Sparrow - Common bird in the streets of Shoshone and also about the railroad yards). I collected 3 Song Sparrows, 1 Flicker, and 2 Juncos. See Field Nos. 1668-1674, The river - here not over 25 ft. wides was frozen over and on top of the ice was about 6 inches of snow. I walked over the river most of the time. About 15 miles north of Shoshone I saw a small flock - about 8 - Sage Grouse, and about 3 mi. N of Shoshone I saw one small flock of Horned Larks. One Marsh Hawk was observed near Zimmerman Hill, some 10 mi. S of Bellevue, On the way down to Shoshone Mr. Neal pointed out the approximate location of a large cave in the lava beds. This cave is about two miles S of Zimmerman Hill, Bellevue Highway Zimmerman Hill. * Three buttes * about where cave is. side road. To Shoshone.

WB Davis 1936. Belleme, Blaine Co., Idaho, Jan. 6. Mr. Head told me that he has seen lots in this cave. When I returned to Bellevue this evening I learned that Twining had returned from Baker Creek and was awaiting my arrival in Hailey. Jan. 7. Drove to Hailey this A.M. to pick up Twining and his outfit. Mr. Linderman lives on the out skirts of Hailey. Here I found Twining with an assemblage of frozen carcasses. Most of these he had retrieved from Linderman's camp site on Baker Creek. See Twining's notes concerning these. He had marten, mink, muskrat, Beaver, Skunk, Flying Squirrel, Tree Squirrel, a Mallard Duck, a Black headed Jay and the remains of a grouse. See Twining's notes concerning Linderman's activities in this area. I purchased two marten, one mink and one skunk pelt from Mr. Linderman. He promised to save us anything he could get.

Talked to about 60 students and put in a few licks against the poisoning program of the B.S. Rupert, Minidoka Co., Idaho, Jan. 8. Twining, Fred Ennis and I left Bellevue this morning about eleven o'clock and travelled thru Shoshone, Eden and Hazelton, arriving here about 4 P.M. The roads were in fair condition although it had snowed about two inches last night. At the Ice Caves we saw about a dozen Black-billed Magpies and two Ravens. Just after we had crossed the Lincoln-Jerome county line we killed a Raven and then another one about two miles E of Jerome. These birds are wary and hard to kill. Both of them were shot on the wing with no. 6 shot in a 16 gage shot gun. About 10 mi. W of Paul Twining brought down an American Roughleg.

At this time we were just keeping abreast the bird, at this same place we saw a small flock of Horned Larkes, but were unable to collect any. About midway between Hazelton and Elow we saw a & Marsh Hawk feeding on a rabbit that had been killed on the highway. About 3 mi. W of Rupert we saw a flock of about a dozen (western) Meadowlarkes, most of them were sitting on a fence; some were on the ground. Jan. 9. Drove to Burley this 4. M. Snowed several inches during the night and a strong south west wind was driftling the loose snow. On our way back to Rupert we stopped at Snake River - in Minidoka County - and hunted for about four hours. I collected 3 Song Sparrowes, a James, and a Western Tree Sparrow; also collected a Black-tailed Jack Rabbit

Twining collected a Kildeer, Tree Sparrow, Junco, Gambel Sparrow and saw a flock of small sandpipers sp? which were feeding in an open "springy" place on the bank of the river. Jan. 10, This A. M. Walter Nelson brought me 13 coyote skulls which he had collected near the divide between Little Lost River and Paheimeroi valley, so we decided it best to return to Berkeley. We packed and left Rupert about 2 p.m. and drove to Albion for the purpose of getting some snow pictures) Found that the snow as all melted except on the mountains and the roads were too rough and muddy to get up there. Left there and drove to Twin Falls where we ate supper and then proceeded on our way at 6:15, arriving in Berkeley Jan 11 about 5 P.M. On Snake River at the Downer Bridge

It was on a hillside bearing scattered Juniperus scopulorum. About three miles west of Burley we saw a flock of about 200 Crows feeding in an open field. Twining took the 16 gage and went after them. They were very wary and he missed the first shot. The whole flock then flew over to the river a short distance away. Twining followed them and killed one bird. Horned Larks were heard here. About 10 mi. w of Burley we stopped and collected three Horned Larks from a flock of about 100 birds). This completes our mid winter) trip to Idaho.

Ants were busy on the captured animals when I visited the traps at 4:30 P.M., One ♀ Perognathus was utterly ruined (maybe by them). Perognathus were taken near Artemisia, especially in places where there were steep banks. The Reithrodonomys were trapped in matted grassy areas as was the Microtus. There was much evidence of Brush Rabbits and I found they had been feeding on the blue, brush-like lupine.

Drove to McCloud via Proville the first day and set out 20 traps along Soda Springs Creek, about 3 mi. SE McCloud that evening. Saw many Myotis feeding above the creek, but failed to take any. Visited the traps this H.M. and had only 5 Peromyscus maniculatus. Nothing in traps set for Sorex palustris. Left McCloud about 10 H.M. and drove to this place, arriving here shortly after 5 P.M. Came via Burney Falls, Alturas to Lakeview. East of McCloud - 9-12 mi. we saw several Eutamias which had been run over by automobiles. Saved one, but the head was smashed. At 15 mi. E McCloud we saw several Callospermophilus. I collected one. It had its burrow under a stump and when I approached it retreated. Stayed down 10 minutes. Saw several Citellus douglasii near Burney Falls, at Beiber we saw the first Citellus oregonus and collected one 3 mi. S Adin. Most of those seen were young or subadult. The one taken was subadult. Many young of year out now.

Made camp by the side of a small creek in association of juniper, sage, Linus muryana), Rhiles etc Placed out 20 mouse traps near the creek; in dry grass in the Artemisia); at the edge of the stream; in rocky situations. Visited the traps this A.M. at about 6:30. Took 4 Peromyscus maniculatus and 1 Zapus). Nothing in traps at edge of creek. This locality is about 200 ft. higher than the town of Lakeview and is reached via Center St. of that town. The creek arises in the snow-capped mountains east of here, Warner Mts? Snowed last night and has been overcast and cold all day. Spent most of the day in camp making up skins of specimens taken yesterday near McCloud, Calif. and here. Last night just after dark a pair of Plocewills was heard across the canyon and at 8:00 - just at dusk - I saw and shot at at Hooved Owl, The canyon runs roughly in an east-west direction and the north facing slope is rocky and overgrown with pines). The south-facing slope is clothed with Artemisia tridentata,

I left my traps out all day in hopes of getting chipmunks, but failed. Haven't slew a single one so far though the habitat of both minimus and amoenus appears to be here. I found the dead carcass of a porcupine and a Nestoma. The skull of the latter was saved. In addition to the traps I had out today, I set out 32 additional ones in likely looking places for Zapus and Microtus.. The Zapus taken this A.M. was caught in a trap set in a runway in the low dead grass in amongst Artemisia about 20 feet from the north bank of the creek. It apparently was dead when I picked it up this A.M. but by 10 A.M., it had revived somewhat and, was able to move its head and all four legs. It had been caught by the tail and one rear leg. I didn't attempt to see if it would revive completely, but at any rate, in contrast to the other strictly homothermous specimens taken, this animal was able to survive cold weather - animal partly covered

Can other hibernating forms withstand similar conditions when forced to? also made two gopher sets across the creek where numerous earthcores, which were thrown out when snow was on the ground, are to be found. Pequegnat caught a breeding male last night with his hands. It was just beginning a new burrow system. It seems that the pocket gophers migrate off the drier hill sides in the summer and go toward the stream where moisture conditions perhaps are more favorable, at any rate most of the earth cores are on the hillside, amongst Artemisia, while most of the occupied burrows are nearer the stream. Most of my additional traps are set along a small hill that flows down a gully from the north. There appeared to be evidence of small rodents in many places along it. Pequegnat found a nest of a fawnce yesterday evening across the creek and about 100 ft. up stream from camp. There were four eggs in it there &

Tequegnat had been able to catch her with his hands yesterday. Today five eggs were in the nest. The nest is on the ground at the base of a Prunus, & about 30 ft from the creek. It is partially set back under a bank formed by the exposed root of the tree. When the ♀ flushed she kept near the nest as long as we remained there - 5 minutes,- and kept uttering her "chip, chip" notes. The ♂ did not appear on the scene. She kept foraging all the while, eating terminal buds from the small branches of the Prunus. A Solnie (Warbler) was attracted by the Junco's calls and came over to investigate. Collected a Robin, Aphelacoma sp?, and Mountain Chickada today. Both the Aphelacoma and Cyanocitta are here, the latter confined largely to the north-facing wooded side of the canyon. May 21. Visited the trap this A.M. at 6:30 and found 2 japus, 2 Microtus mordax, 199 & discarded,

Used peanut butter for bait, but doubt that is any better than rolled oats. Maybe a mixture of the two would be better. The two Zapus were taken in the same general area where the first one was taken, one in the same trap and at the same spot. The other, with damaged tail, was taken under some fallen Artemisia where I had taken a Peromyscus the previous night. Nothing in the gopher sets. Sun is shining this A.M. but the sky is cloudy. Froze ice on water in our pans last night. Pequequat and I took a hike up the canyon about a mile or two. Left camp at noon and were back about 3:30. The canyon broadens out about a mile from camp and the creek forks, one coming in from the north the other from the east. I followed the east fork for 1/2 to 1 mile. The elevation is about 200 ft. higher than camp and the Pines and Juniper Gives way to Willows, Quaking Aspen, yellow Pine and fir. In most places the sage brush is dwarfed. Also some.

W.B.Davis 1936 2 mi. E Lakeview, 5200 ft., Lake Co., Oregon. May 21. Arctostaphylos. This, I believe borders on lower Canadiana, I found Juncoes to be the commonest birds in the area I visited last. They were paired off and perhaps were breeding judging from the nest discovered near camp. I collected three males. Also found House Wren, Lewis Woodpecker, Meadowlark, Wood Pewee, Lutescent Warbler, Brewer Sparrow, Fox Sparrow, Green-tailed Towhee, Flicker, Western Red-tail, Mountain Bluebird, Robin in this area, also Steller Jay. We saw a Marmot on the rocky north facing slope of the canyon about 1/2 mi. above camp. Pequignat tried for it but it got away. At this same place, on the south facing slope, along the road, I collected a Bushtit, and saw a Sparrow Hawk. We saw several Callospermophilus, one collects, I found one that had its den in a dead stump. Pulled the stump to pieces and had the Callo in my hand but it got away and down a burrow in the ground. Saw t's Eutamias amoenus; collected one, a ? which was suckling young, that had her home under a big stump along the creek. Saw the other one on the bridge at the forks of the creek. Shot at it,

Pocket gopher workings were abundant in the flat along the east fork, especially on the N-facing slope of a small wooded knoll. Numerous earth cores were found evidencing the fact that snow fell here and remained on the ground some time this past winter. I visited one snow bank on the N-facing slope of a small hill. It was near here I saw the Luteent warbler in the Aspens. A pair of Juncos had their territory near the snow bank, and judging from the actions of the ? she must have had a nest nearby. The Lewis Woodpeckers were in the flat proper where Junipers were found. I observed them alighting on the ground to feed, and also that the first fly-catcher fashion. Perhaps this woodpecker is as aberrant as the Flicker in its feeding habits. Found two old House Wrens nests, both in large stumps near the creek. The Bushtit, a ?, evidently had nested in this canyon, judging from the fatty brood patch on the belly and breast. Set out 30 traps in the Zapus area and had 26 out up a small draw. Reset there.

WB Davis 1936. 526 2 mi. E Lakeview, 5200 ft., lake Co., Oregon. May 22, Out of the 56 traps set last night I took the following 18 Zapus p. major, 1M & Peromyscus maniculatus, 1498 of same, and 149 ? Microtus mordax. Only the Zapus was saved. It was taken in the same trap at the same place as two others, although I had 30 traps in the small area, 150'x 40', where I had taken them previously. Spent the morning in camp making up specimens). Looked at the Jamesi nest about 11:30. Still 5 eggs, & incubating. Took two pictures of the nest. Did not have my egg drills along, so left the set and the parent birds. Packed up and left this camp about noon. Found out we had been camped in the Warner Mountains, type locality of Zapus p. major. Mammals collected x seen at this camp. 1. Zapus p. major 2.

WB Davis 1936. Alkali Lake Ranch, lake Co., Oregon. May 23, Left Lakeview yesterday about 12:30, headed for Burns). The highway is paved a short distance north of Lakeview and then gives way to a rough, gravelled road. We took our time and stopped at Alert Lake - now containing considerable water - for about 1/2 hours). Collected 3♀ and 1♂ Redwings near the south end of the lake. A small colony was nesting in a reedy area at the edge of the lake. Young, about two day old, were in several nests. Of the two sexes, the ♀ Redwing is much more wary than the male. In addition she is much faster in normal flight, We saw hundreds of gulls, Caly or Ring- bill, on the lower end of the lake. Also a flock of some twenty-add Avocets and one small flock of some shorebirds about the size of a Godwit. The lake is about 20 miles long and perhaps 8 or 10 miles wide at its widest point, and quite shallow. To the east of the lake a mountain mass, devoid trees, rises rapidly from the lake. The rocky, basaltic nature of this lake facing slope offers habitat for the Marmot Rock Wren, and Canyon Wren; the former observed, the two birds

Stopped to fix it, and saw two families of Canada Geese along the shore of the lake. The young were about the size of Mallard Ducks, two of which flushed from a pond near the goose. Drove one to this locality through typical Great Basin Sage Desert country arriving here about 6 P.M. We turned west of the main highway about a miles north of Gray Butter and crossed the extreme north end of the now dry lake bed. This ranch has now it the only spring in this area. The surrounding country is relatively flat, and, at some distance from the lake bed, covered with Sage. The immediate area is flat, highly alkaline, and, where shrubs are growing, covered with spiny triplox. The spring overflowe and supplies water to a few acres of ground which is grazed no one is living at the ranch now, but it is still occupied, and a few cattle are found hereabouts.

W.B.Davis 1936 Lake Alkali Ranch, Lake Co., Oregon. May 23. 530 The spring is about 30 ft. in diameter and about 9 ft. deep. It is heavily rimmed with rushes in which a colony of Yellow-headed Blackbirds have established themselves). Also a pair of Yellow-throats are here. Redwing Blackbirds) have established themselves in the short marsh grass and are promptly driven from the rushes by the yellowheads whenever they invade that sanctuary. Hundreds of small fish are in the spring. We caught 10 of them last night and had them for breakfast this morning. They appear to be a kind of Cyprinidow . The largest one is about 10 or 12 inches long. I set out 20 mouse traps last night, 4 around the spring, and the rest in the @triple areas where there are semi- sandy knolls. Caught nothing at the spring, and only 2 & Peromycus maniculatus in the @triples. Pequegnat just returned from a short hunt - 2:00 P.M. - and had a Lepus californicus F, and said he saw an Ammodermophilus. Two pairs of Barn Swallows are established at this ranch, and a pair

Last night just at dusk a flock of about 200 Ravens circled over the hay stack, as if looking for a place to roost, and then flew away headed south. They came from the east. Have seen several Ravens today. An old granary, once used as a home, had hundreds of pellets under one of the rafters on the second floor. A feather from the tail of a Raven indicated that this species roosted there and had regurgitated the pellets. I examined some of the pellets and found remains of rabbits and caudal vertebrae of some larger mammal. In this same building a pair of Barn Swallows and a pair of Say Phoebes are nesting. Killdeer are here, too. There are several good sand dunes on the east side of the lake bed and a few at the north end, but none here. On the east side of the lake bed I saw evidence of the presence of Dipodomys.

This place is just at the gate that enters the ranch. The dunes were rather low, 10 - 15 ft., and in places were composed of an alkali base with drifted sand on top. The chief vegetation was (Atriplex, Artemisia, and Chrysothamnus). I took only 2 [illegible] Microdipodops) megacephalus and had the terminal third of the tail of a Dipodomys in one trap. Dipos tracks were everywhere and nearly every trap had been visited but not disturbed. Used rolled oats for bait. Something else is needed. The two Microdipodops were taken (1) in coarse sand - caught by the head, so had taken the bait, (2) in very fine) sand,-caught by the tail which was thus badly damaged. Pequegnat had out 20 traps in a similar area and took one (Peromyscus) maniculatus and 1 Microdipodops. we set out 7 traps around camp, by the cabin, and around the food cases. Took 2 Peromyscus maniculatus, one young, which was discarded, Myotis californicus were rather [illegible] melanarchus

W.B. Davis 1936 Alkali Lake Ranch, Lake Co., Oregon, May 24 common here last night. The first one was seen about an hour before dark and from then on until about two hours after dark they were seen and heard. They were feeding for the most part over the open pond west of the ranch house. Occasionally however, they foraged over the [illegible], desert areas. The one I collected was foraging in the latter area. We left this camp at 10:30 A.M. headed toward Burns, Oregon. Snake River Bridge, Ontario, Malheur Co., Ore. May 26. Drove all day passing through Vagontire, Burns, Vale and Ontario. We arrived here about dark and got permission from Mr. N.C. Kreis to camp and collect on his property which borders the river here at the bridge. The highway cuts his property into two sections. We are camped on the north side of the highway about 100 yds. from the river. Yesterday - May 25 - I hunted Cistellus mollis from 6 A.M. to 10 A.M. and then again late in the afternoon - about 6 P.M. These animals are the vigils of Howell's

W.B. Davis 1936. Snake River Bridge, Ontario, Malheur Co., Ore. May 26. This locality is only 11 miles east of the type locality of Viglis - at Vale. They are abundant here in the drier portions of the fields and along the river bank. I collected 7 adults - all very fat - 6♂ and 1♀, shot several others but saved only the adults. They are highly colonial, and each burrow which has young usually harbors from 5 to 8 plus the adults. One colony which I have watched carefully had several family groups. One family consisted of 2 adults - the 2 collected - and 8 young. 7 of which I trapped in a steel trap set at one entrance to the home burrow. Four of these I have alive in a cage, and in addition another young one taken at another, quite removed burrow. There is evidence to indicate individually that the young are preparing separate burrows for themselves. Small entrance 60 x 80 mm. in one instance, with fresh earth in the mounds are commonly seen. Trapping at such places results in the taking of only one young individual. I tested out the ability of this squirrel to swim. Caught one in a steel trap which broke its front left leg and threw the squirrel out into the river.

It seemed to be able to swim as rapidly as a small dog. I kept the animal in a cage all night and next morning when I took the lid off to look at it, it jumped out, ran to the edge of a ditch 2 ft wide full of water, entered the water and swam against the current up under a bridge where it escaped. These two instances show at least that these squirrels can swim. However, the river here appears to act as a barrier to them for on the opposite side of the river Citellus idahoensis is found. I measured the width of the river at this point by pacing off the width from shore to shore via the bridge. It was 255 paces of about 30" each. a small island 30 paces wide is 30 paces from this, the west bank. The main current is in the channel between the island and the east shore. Peguyrat reported seeing ground squirrels on the island. This place was doubtless reached during the period of low water.

W.B. Davis 1936. Snake River Bridge, Ontario, Malheur Co., Oregon. May 27 Last night - about 8 P.M. - I set out 40 mouse traps on the east Idaho- tank of the river. Had them set in a marshy area where water seeps from the irrigated land back into the river, and in semi-sandy areas covered sparsely with Artemisia & duthu Sarcobatus, Grayia, & Chrysothamnus. In the marshy area nettles, willows, water cress, roses, currants, etc were forming a semi-thicket. Caught nothing but snails. Had 30 of them piled up on one trap. The bait was gone from all the traps in the marshy areas. Pequeguat set in the Artemisia on this side of the river and could catch nothing but 2 toads, etc. catched 2 young gophers today and 4 yesterday. These are the big Thomomys townsendi. They are fairly common here and cause the farmers a great deal of damage, especially in the way of interrupting irrigator activities. We left this camp about 1:30 headed for Hornedale, Owyhee Co., Idaho.

WB Davis 1936. Homedale, Owyhee Co., Idaho, May 28, 540 Arrived here yesterday afternoon. Drove via Nyssa, Oregon, Parma, and Wilder, Idaho. We are camped on the W.W. Aldrich ranch on the N side of the Snake River in Canyon Co. I worked the south side of the river and Pequegnat worked the north side. I drove across the river and made four sets for Thomomys in the field of Earl Vail about 1/2 mi. W of the town limits. The gophers were in his alfalfa and also along the edge of his corn field and along the irrigation ditches. Gophers are scarce in this area because the irrigation company has been com- bating them in conjunction with the B. S. I saw several Citellus mollis in Mr. Vail's field and also in a field just to the east of the bridge crossing the river. This morning I found three gophers in my four sets. They are the large townsendii type. Hunted for more burrows but was unable to locate any. The south side of the river in the area of Homedale is about 50 ft.

W.B. Davis 1936 Homedale, Cwyhwe Co., Idaho. May 28, lower in elevation than the north side, a high bluff borders the river on the north. The whole area on both sides of the river is of a sandy-clay type of soil, but on the higher hills and plateaux, a short distance from the river, the clay-like soil is covered with superficial layers of sand which in some places is quite deep - 2 to 3 ft. The native vegetation on each side of the river is largely Artemisia, Atriplex, Grayia and some Barcolatus. The presence of Atriplex is indicative of alkali in the soil. Along the river the willows form the chief vegetation. June grass is the dominant grass in uncultivated areas. Jawrisend gophers are on both sides of the river here, but there are no ground squirrels on the north side in this immediate area. Mr. Aldris told me that they were common on the north side when he moved there 15 years ago. However, intensive poisoning campaigns had effectively removed them. He reported seeing them about 10 mi East of here on the road to Nampa!

Homedale, Owyhee Co., Idaho. May 29. Last night I set out 20 mouse traps in a sandy area just south of the bridge, and 30 more in a sandy area on the brow of the first hill west of town to the south of the highway. The traps were placed in Atriplex chiefly, and some Sarcobatus. Very little Artemisia in the areas trapped. I caught nothing in the area just south of the bridge, but in the other area west of town I took 4 Dipolomys ordius (28, 29 mus. musculue), and 1 young & Reithrodontomy which was discarded. I also set out three steel sets at the mouth of Citellus mollis burrows. Took two adults today in these traps. Both of them were molting all over as indicated by the skins when they were removed from the animals. One Citellus Oreganus was taken along a ditch. This species is not at all common here; this was the only one I saw. The apparent absence of Peromyscus puzzles me. We were unable to take them at Ontario on either side of the river and here again neither Siguist nor I took any in our traps. They must be in this area but farther

W.B. Davis 1936 Homedale, Owyhee Co., Idaho. May 29, look from the river). I left my traps out all day in hopes of getting Eutamias or Emmors, one of which I saw yesterday evening but was unable to collect it. I did find one which had been suckling young in one of my traps when I visited them about 2:00 P.M. The animal had lain so long in the hot sun that its preparation as a study specimen was difficult. In addition, the animal was in full process of a complete molt. I saw another Ammoe today when I visited my traps but couldn't get it. Collected several Leopard and Whip-tailed Lizards which are very common in this area. They are living where the sand is heaviest and in association with Atriplex, Dipodomys, Ammoopermyllo, etc. Collected several Redwinged Blackbirds which were occupying a cat-tail slough just south of the river bridge. Barn Swallows are quite common over this slough, and Bank Swallows are common everywhere. Also collected a Meadowlark near this slough.

W.B. Davis 1936. 544 Homedale, Owyhee Co., Idaho. May 31, On the evening of the 29th I set out 30 additional traps — besides the 30 west of town; The others were taken up in an area (sandy) about a mile west of the first hill west of town. Set out 7 rat traps too in this area. Next morning I had 18 Dipodomys 8 of which were adult or nearly so, and 25 Perognathus parvus. Lates were taken in not so sandy areas as were the Dipsos. Caught another Ammospermophilus in a mouse trap. She also was suckling young. She was in better condition than was the first one and made a better skin. At that, she must have lain in the sun for an hour or more before I got to her. Night hawks are quite common in this area, 3's were noted feeding early in the evening.

W.B. Davis 1936 Mt. Harrison, 10 mi. S Allison, Cassia Co., Idaho. June 14. Moved camp from the Wickes ranch at Elba, where we collected from the 10th to the 13th, to this locality. We are camped about 3/4 mi. up the S fork of the creek that flows in Howell's Canyon. Turned S at the ranger station. There is an abundance of water in the creek and numerous patches of snow are about our camp. Deep snow banks are hanging on the east & north slopes of the hills. The dominant trees are Abies alpine, Pinus murrayana and Populus tremuloides. On the tops of the hills and on S facing slopes are nearly pure stands of Artemisia tridentata. Set out 30 traps along the creek and by and under fallen logs in the conifers. Look 2♂ Eutarsias anoreus and 9♀ Peromyscus maniculatus.
