Hooper, 1934 Berkeley, Alameda Co., Calif. Oct. 30, Skull Only 70 ? Cerognathus spinatus 183-109-20-5 This specimen collected by S.B. Benson in Andreas Canon, 9,000 ft., Riverside Co., Calif. There is a duplication in his collecting numbers, 1220, one being skin & skull, one skull only. Therefore to prevent future confusion I am giving this another number. Benson himself furnished the specifications. Dec. 21, Alcohol 71? Dipodomys mohavensis This rat was collected by S.B. Benson on Aug. 1, 1929, at 4700 ft., Freeman Canyon, Kern Co., Calif.. This data was on the original tag; but no sex or measurements were given. A search through Benson's field notebook and the catalogue (of numbers included in accession 3331, which covered this trip in the Los Angeles & Kern Co. regions) fainted of an failed to reveal any alcoholic D. mohavensis. Therefore, to guard against future mixup, I am giving the specimen my number.

Hooper, 1935 Berkeley, Alameda Co., Calif.; [Jan. 3,] The following six birds (Col. Nos. 72-77) were collected by Ralph Ellis at the locality, "5 mi. W. Princeton, Colusa Co., Calif., on Dec. 30, 1934, and were presented to the Museum by the above collector. Due to the absence of W. C. Russell, I was instructed by Dr. E. R. Hall to prepare the specimens for the skeletons only and am therefore affixing my own collecting numbers to them. 72? Bittern 73? Marsh Hawk 74? Coot 75? " 76? " 77?

Hooper 1935 Berkeley, Alameda Co., Calif. The following specimens were collected at or near Big Basin, Monterey, Co., Calif. in the spring of 1933, more definitely, probably in March, April, or May. They were presented to the Museum by C.F. Smith as part of accession 4550. Because the original tags were lost and no specific data than that given above was available, I am affixing my collecting numbers. The specimens were collected by either C.F. Smith, R.E. Smith, or Jno F. Ashley and may belong to (see skulls only) belong to certain skins included in the accession. However, this we do not definitely know.

Bishop, Inyo Co., Calif. May 21, Last night I set out 30 mouse traps, about 10 spaces apart, at the above local- ity, which is due east of Bishop on East Line St., the main road to the Owens River. Squaw tea (Ephedra) sage, and other xerophytic plants indicate the zonation to be Lower Sonoran in this immediate area. Many Kangaroo rat burrows were visible in the day, sandy soil. Most were within a foot from the base of a sage bush, however a few were out in the open, 5 or 6 ft. from any vegetation. Some burrows were open but the majority were at least partially closed by sand, only tracks and tail marks indicating that the holes were inhabi- ted; the diameters of the burrow mouths varied, though seemed to fall into two general size groups, one approximately 1 1/2 in. in diameter and the other approximat

About one half of the traps were set in this habitat and the other fifteen placed in the adjoining Bishop Cr. bottom- lands. Here a few grassy areas could be found on the slightly higher ground bordered by the stream channels proper, which were, for the most part, overgrown with cat-tails (Typha). Very little water at any season flows down this part of the creek; all but this slight seepage is diverted, also at a point approximately 1 mile west, into the Bishop canal, which, in turn empties into the Owens River near Big Pine. Microtus signs could be found in the grassy areas. The traps this morning yielded the following mammals (+ 1 Neothodontomys, which was discarded): 0783 Dipodomys m. leucopus 314 - 191 - 46 testes large 0784 " " 278 - 172 - 43 0785 " " 287 - 170 - 43 testes large 0786 " " 282 - 170 - 44 0787 " m. meriami 225 - 131 - 37 " 0788 " " 215 - 126 - 38 " 0789 Neothodontomys m. megalotis 135 - 66 - 18 "

May 23, Laws is a small town 5 miles NE. Bishops; it lies at the end of the railroad line (Mohave -> Laws) and is about 3/4 mi east of the Owens River, actually lying in the old river bed. My collecting locality is, thus, on the west bank of the river bed and 1/4 mi. west of the present river channel. The bottom lands are covered with grass and serve as forage ground for cattle. Mammal signs, other than that of Lagamorpha, is scarce. However, on the adjoining, sandy bank near sage bushes, burrows, tracks, and fecal material is fairly abundant. It was in this latter habitat that I set out fifteen traps. Black-tailed jackrabbits (Lepus c. deserticola) and Cottontails

The rat traps were set near Neotoma buts, however were empty, though spawning; the above wood rat was caught in a got. mouse trap. The steel trap was placed at the opening of a large burrow at the immediate edge of a stream, however yielded nothing. The above locality is on the P.T.

Sept., 1935 3 mi. W. Druness, 2 ro ft., Marin Co. Calif. June 14, passes westward. The Bishop Pine (L. muricata), mountain lilac (Ceanothus sp.), madrone (Arbutus menzesii), alder (Alnus rubra), buckeye (Aesculus californicus) association gives way to a dry hard chopparal association in which the following "major" plants were noted: Bacaris, B bracken, oak (Q. agrifolia), wild raspberry (Ribes sp?), willow (Salix), and hazlenut [the latter two especially along the creek bottom]. Along the creek a dense growth of sword grass, thistle and glass affords a splendid habitat for meadow mice (Microtus), shrews (Sorex), and jumping mice (Zapus). Other areas in the harder chopparal serve as suitable areas for wood rats (Neotoma). The primary purpose of this trip over here to Marin Co. was to secure specimens of and learn about the habitat of mountain beaver (Aplodontia), jumping mouse (Zapus) and wood rats (Neotoma). I found no definite signs of Aplodontia here, 3 mi. W. Druness, where Taylor, Camp, Grinnell and others trapped in 1913. The postmaster here told me that mountain beaver are still found in

He also said that he had seen them high up on Inverness ridge near the summit south of Inverness (about 3 mi.). Coyotes, he said, were giving considerable trouble to stock owners in this region. On the property of the Inverness Gun Club (where I trapped) I saw a group of approximately 15 grouse which were flushed from a large alder tree. A large, fat doe and two fawns were also seen down in the broken-raspberry- sword grass thickets. Brush rabbits were abundant. In the Bishop pine association the following birds were seen: Calif. quail (in pairs), russet-backed thrush (numerous but seen singly), Santa Cruz song sparrow, white-crowned sparrow, western robin, Raven, Red- shafted flicker, Calif. jay, junco, golden pyleolated warbler, spotted towhee, wren-tit, Rufous humming- bird.

Itinerary and Accounts August 7, In company with Art Kip, I left Berkeley this morning at 9 A.M. with the mouth of the Stanislaus River as the destination for the day. While passing through the hills west of Livermore at Altamont (a railroad station listed on the Shell road maps) we noticed a man distributing prison grain to ground squirrels. About five miles east of Tracy we turned southward and eastward, passing through Yarmouth to Vernalis. At Vernalis we took the

Auger, 1935 3 mi. NE. Vernolia, San Joaquin Co., Calif. August 7, As to mammals present now, he gave us a little information. A mountain lion (?) was living along the river bottomlands up until last year. It has not been seen this year. Other animals seen fairly frequently include: coon, opossum, kit foxes, coyote, skunk and wood rats. These were all inhabitants in the bottomlands before the extreme high water of the springtime of this year. However few carnivore and no wood rats have been seen since. The water drowned them all, he said. Indeed, he seemed to be right; for we searched for seven hours over as many miles of territory and found bits of only two wood rats. These had been completely submerged and not occupied since. And since the water covered the whole of the bottomlands from flood bank to flood bank (the first time in many years) it is not surprising that no more evidences of wood rats could be seen. Fifteen rat and mouse traps set overnight yielded no specimens. Dense thickets of wild rose, nettle,

1935 3 mi. N.E. Vernalis, San Joaquin Co., Calif. August 7, and willow interspersed with a few valley oak and California bay trees offered what seemed to me to be ideal situations; habitats, for wood rats. “Coon,” kit fox, and possibly (?) opossum tracks were seen on the sandy shores of the river proper. If they are here, rodents and other small animals must also be here! Yet not even a white- footed mouse found my traps sufficiently enticing to spring one of them. August 8, Since nothing was in my traps this morning we decided to pick up camp and move on up river to some so-called-by-Olm “virgin land” that was not along the river bottom and had not been flooded by the water. This place is approximately four miles farther north from here, near the Banta-Carbona irrigation canal pumps. After spending two hours hiking, or more exactly tearing our way through brush (which seemed to have been above water) we decided to try for some of the stream beds draining eastward from the Diablo Range.

ber, 1935 10 mi. W. Justin, Stanislaus Co., Calif. August 8; On the way south from the aforementioned locality and about 7½ mi N.E. Vernolis I picked up a Thomomys skull by some of Citellus b. beecheyi holes that abound in the region. I also noted seven prairie falcons and one sparrow hawk sitting on telephone wires and poles at the same locality. The prairie falcons are much more wary of motor cars and take to stones approach wing much sooner, than does the sparrow hawk. Traveling south from Vernolis we reached Crowe Landing and there turned west up Crestimba Cr. to the ranch house at the end of the road, about six miles west of Crowe landing. But here again the absence of brush and suitable food and cover made a stop here for wood rats seem absurd. So, at the suggestion of the man residing in the farmhouse we returned back down Crestimba Cr. in order to connect with the road extending from Newman up Las Garzas Cr., where it was reported, we would find many wood rats and abundant brush. At Newman while in a service station we chanced to meet a Mr. Klehn who

oper, 1935 10 mi. W. Justine, Stanislaus Co., Calif. August 8, owns property on Las Garzas Cr. He kindly offered to let us camp on his property and, since he was planning a trip there later in the afternoon, said he would accompany us himself. At 4 P.M. we left Newman, Stanislaus Co., traveled ten miles over roads boasting in the distant of better days, fast and arrived at his grounds which I will list as Camp 1 selecting since it is here that I will stop for at least two nights. 10 miles W.

Manzanita, Coulter pines, live-oak, ash, and some poison oak are all found here, chiefly on the north- facing slopes. Chenise and Artemesia constitute the dominant plant growth on the south-facing slopes. Birds seen here at camp include the following:

August 9, Brown toucan, Brown thrasher, valley- guail, California jay, green-backed goldfinch, mourning dove, turkey buzzard, wren-tit, plain titmouse. The guails are very abundant, several coveys (brood of year most likely) of from 8 to 12 birds each having been seen within an area of 1 square mile. The south slope of this canyon looks like it should be suitable environment for pocket mice and perhaps kangaroo rats. However, the chances of securing wood rats will probably be none too good. The brush is too open and too dry. Last night I set out thirty mouse and rat traps (20 and 10 respectively) along the creek bottom, and up each side of the stream bed. This morning I found 3 Peromyscus truei and 1 Perognathus c. in my traps, a very poor percentage. A thorough poisoning campaign carried on by the landowners themselves against rodents two years ago probably reduced their number of small native animals to a low level. Woodrats, once fairly abundant here are now seldom, if ever,

And considering their "prolificness", hardi- ess, and general adaptability, this is easy to imagine. The cottontail I shot while collecting my traps this morning. After talking with several of these San Joaquin Valley farmers and stockmen I am contacting a angle different from that presented by scientific societies. How shallow, transparent and at times utterly irratio- al are these agricultural men. Very often they realize something of the complexity of nature but most often they "can't see the forest for the trees". August 10, Last night I set out 31 traps on the opposite hillside from that at which we are camped, that is on the south-facing slope. The slope is very steep, about 35%, and the soil as very thin covering over the harder sedimentary deposits underneath. Here, among chemists and wild buckwheat I set out the traps.

Since three of the white-footed mice were not over two months old they were discarded; the other specimens were made into study skins. 7 mi. E. Mariposa, Mariposa Co., Calif.

Digger Pine (Pinus sabiniana, Quercus kelloggii, Ceanothus sp., Rhus diversiloba, Alder (Alnus rubra?) Arctostaphylus and Salix sp.? constitute the major portion of the plants present, hhowever.

Judging from trapping results of last night the species of mammals here are not too abundant. From 38 traps (13 rat and 25 mouse) set along the creek bed and under willows, poison oak and oaks & Peromyscus maniculatus only were taken. These four three mice and one Bufo, captured in a field of wild oats near the creek, constitute the total catch for the day. I saw two Entamias merriami running about on granite boulders under oak trees and caught the odor of a skunk. No other animals have been seen, though nests and droppings of wood rats and mounds made by pocket gophers are abundant.

August 12, Out of thirteen rat traps and twenty-five mouse traps set along the creek only a single mammal was found this morning. The specimen, a Peromyscus maniculatus, was discarded. Mammal holes are abundant, sign is in evidence at many places. Why don't I catch more specimens? The traps are set in likely places and baited with the usual moistened oatmeal. Perhaps (rodents) the animals are feeding on fresh cuttings of plants during this exceptionally hot period which has endured for the past two days. Tonight I shall try pieces of prunes as well as oatmeal and see if the results are any better. Mrs. Woodard says the gophers and moles play havoc with her flower garden. She showed me several elevated "sunways" of moles as well as more gopher

They were found hanging with- in several old, black, rubberized coats found hanging in one of the outhouses on the Woodard property. Droppings under- neath each roosting place and parasites commonly known as "sheep ticks" on the coats indicated that the bats used these places regularly. Wood rat nests are located among the granite boulders, in the crevices, for the most part. In such situations the hut cannot be more than two feet high, or at least none have been seen any higher. The houses are made of driftwood; no fresh cuttings have been seen around these huts. One proper nest was found lying out on the granite boulder not covered by any sticks but protected to a great extent by the overhanging rocks which protruded outward for about six feet. One old nest was located up in a live oak tree about six feet from the main trunk, eight feet from the

Perhaps streatori chooses rocks for his home site and does not construct huts the size of those built by the coast forms. These old huts found along the San Joaquin River were only two or two and one half feet high. However, quite likely some of the covering material had been removed at the time of the high water. Aug. 13, Last night I set out 25 mouse and 12 rat traps in a different type of habitat. About 1/2 mile north of camp there is an old deserted cabin placed in a sheltered glen near the top of a hill and about 3/8 mi. from any creek bottom. About this house are several outhouses and brush piles, all of which had fresh fecal material and trails seemingly made by wood rats. At such vantage points I set traps baited with either cheese and oatmeal or pieces of

Most of the mouse traps were set near Arctostaphylus bushes and near rocks in the hope of capturing some "Kangaroo rats" which Mr. and Mrs. Woodard claim are present here. This morning I found one young wood rat, one juvenile Beechey ground squirrel and three Peromyscus californicus in my traps. Several traps were sprung and found empty. The traps baited with dried prune and oatmeal had not been touched, while those baited with cheese and oatmeal or oatmeal alone either held an animal or were sprung. The woodrat was caught at the edge of a lumber pile under which it probably was living. Perhaps many of these smaller holes seen in this region belong to the californicus parasitic mice and are not wood rat nests at all. Examination of the fecal material saved may throw some light on the question, for it is matrix of this size and shape that is abundant everywhere about crevices in rocks, brush piles, and other suitable places.

Aug. 13, Mr. Woodard believes that the relative scarcity of wood rats in the traps can be explained by the fact that fruit is so abundant now, i.e., manzanita, poison oak and other berries, that they will not take dried oatmeal and grain. However, if this be so, why wouldn't they take the dried prune bait? I found another bat, genus mystis, hanging in the barn. This is now preserved as a study skin. No other bats, other than those of the above genus, have been seen flying about in the evenings. This afternoon, because of pressure of time, we must leave this region. I would like to spend a week here now to devise and test some ways of capturing more of the animals present here. No kangaroo rats, chip- munks, skunks, and coyotes have been caught though have been heard or seen. At 1 P.M. we leave for Yosemite via the Wawona road.

On the way over here I noticed few mammals. Golden-mantled ground squirrels in the Canadian zone, Bellling ground squirrels, chiefly in the Hudsonian where blooming flowers indicate that the height of springtime has just been passed. Tahoe chipmunks in Canadian, alpine chipmunks in Hudsonian were all that were seen during our mid-day drive. Last night I set out twenty mouse traps along the sandy, sage and squaw-tha-covered sandy banks of the Owens river bottomlands. Kangaroo rat holes were abundant. This morning I found 3 D. leucogenys? and 4 P. m. lonoceriensis in my traps. All but two of the Peromyscus were preserved as study skins; the two white-footed mice were discarded.

Only more extensive trapping will throw light on the question. I saw no cottontails while traveling to and from the trapping locality, howerver did see six or seven black-tailed jackrabbits. Cottontails were abundant here in May, why didn't I see some this time? Tomorrow morning we leave for Berkeley via the Sonora Pass Road, thus concluding this brief vacation trip.

At approximately 3:30 P.M. we arrived in Vernalis, which is a small town just north south of the San Joaquin - Stanislaus and is county line, on the road from Tracy to Newman. Vernalis itself is in San Joaquin Co. Inquiring at the general store where "Kincaids Ranch" was located (the locality where R.J. Gnr in 1931 took two Nestors foxes and several brush rabbits), we were told that the ranch had passed into other hands and that the new owner quite likely would not be amenable to any trapping activities. Therefore, we decided to approach the officials of El Solyo Ranch, a large ranch approximately 3mi. due S.E. of Vernalis. a permit to hunt & camp on the "game reserve" which includes all the river bottomlands in this immediately vicinity, was given readily. However, a reconnaissance over the area soon convinced us that trapping would prove to be unprofitable, since most of the land bordering the river had been either

Without further ado, we drove to the property of Mr. Ohm, where I camped for one night earlier this summer. Mr. Ohm's house is situated at the site of a town once known as Joaquin City. It, also, is no more. Mr. Ohm said that he had seen no more wood rats since the time of high water, but if we were interested in bats, he could show us where were "plenty". Accordingly, he led us up to the attic of his house. There on the tops of rafters and joists we found feed material of bats about one inch deep. On crevices behind joists, etc. were "numerous" bats which could not be reached by us even with the aid of forceps. After setting up camp out on the "bottomlands" approximately 1/4 mi. from Ohm's house, I set out 31 mouse traps and 14 rat traps. These all were placed near or along the face of the flood banks and under willow bushes (Salix sp.? ) and oaks (Quercus lobata) which are quite characteristic of this lower Sonoran, and Oregon ash (Fraxinus oregoni)

San Joaquin R., 3 mi. NE. Vernalis, San Joaquin Co. Calif. Oct. 18, riparian association. This morning I found the following mammals in my traps: 1 Nestoma fusipes and 3 Mus musculus. The wood rat was caught beside a willow clump and a fallen oak log. Within the log it probably nested. I found more fresh sign elsewhere but caught no more rats in my settings placed nearby. Apparently some animals survived the recent flood and are now 're-claiming' the bottomlands. Last August, 1935, I caught nothing in fifteen trap nights. Now in forty-five trap nights I get four animals! But more important, Dave Johnson took 5 mammals set out of 24 traps last night out 1/4 mi. from the flood banks to which continuously the flood waters reached for '3 weeks' [quote Mr. Ohm]. This reclaiming of territory must take place to a greater or less extent each year. For birds seen, see notebook of D. H. Johnson.

22, 1935 San Joaquin R., 3 mi. NE. Vernalis, San Joaquin Cr., Calif. October 19, Yesterday we found fresh gopher workings near the border of the river bottomlands. The soil here is of the sandy-loam type and a light tan in color. Vegetation in the area includes(1) a small annual which grows very low over the ground forming a dense mat and bearing fruiting bodies that are covered with small spines; (2) anthium = "bur-weed" with rootstocks slightly fleshy; cavadesne average height of plant 3 ft. We set out six gopher traps in the runways (which seem to run no deeper than 6 in. beneath the surface) of these workings. We examined the traps at 3 P.M. and found that one had been covered with dirt. It was reset; and at 5 P.M. we found degopher in this and another set. One of these specimens bears my collecting number (1489); the other, taken in a neighboring burrow, is being put up by D.H. Johnson (924 ?). I found a skyla along the shore of one of the many sloughs or ox-bow lakes found here. I set out 10 mouse traps and 30 rat traps last night. The rat traps were placed near wood rat nests, the mouse traps at intervals approx. 20 paces under oaks and willows for the main purpose of

San Joaquin R., 3 mi. N.E. Vernolis, San Joaquin Co., Calif. October 19. Providing some sort of continuity to the trap line. At least 15 wood rat nests were found, all with fresh sign about them. Though most of the nests are in oak trees (Quercus lobata), some were found on willow stumps. They were composed of dry, water-worn sticks up to 4 ft. in length x 2 in. in diameter, were not over 2 ft. in height and were placed at heights above the ground varying from 3 feet to 20 feet. We so disturbed one nest in an oak tree that 2 rats [1 juv. ♀] and 1 ♂ with 4 conspicuous inguinal mammas ran out. One was shot, the other (? perhaps) was trapped last night by D. H. Johnson. The rats here are distinctly inclined toward arboreal habits, more so, apparently than other members of the Neotoma group. No nests have been seen on the ground, though burrows at bases of trees harboring nests were seen. Is this an extreme adaptation of a tree-inhabiting characteristic of the Neotoma group, made extreme because of the annual flooding? Perhaps selection has been active in weeding out the non-tree climbers.? At any rate there are certainly many more rats here than I expected, and thus are apparently more nests than were her

The animals must have remained in the trees during the flood time, when the ground was covered with water. This morning D. found two good adults in my traps. Both were taken from traps set up in the branches of the willow-trees. They bear numbers 149 + 150 (mammas enlarged). The mouse traps were undisturbed. One wonders why the Peromyscus maniculatus are not plentiful here. They are 'ground-dwellers' and could easily be drowned out by the high water. However, so are gophers, yet one gopher system was found out approx. 3/8 mi. from the higher flood bank, in a region which was under water for a depth of at least three feet. The animal must have migrated this distance since March or April when the water was so high. Berkeley, Alameda Co., Calif.

This Knoll is a monadnock-like hill that rises from the low-lying Bay shore and the low Berkeley foothills. The vegetation includes Eucalyptus, Baccharis, fellers tease and numerous kinds of annual grasses. Along the Tidelands in the Salicornia I noted pipits, audubon warblers, and English sparrows. Among the Baccharis & tease song sparrows, white-crowned sparrows, juncos anna hummingbirds, English sparrows, house finches. On the grass-covered hillsides & flat areas meadow larks were heard. A kingfisher was seen sitting on a telegraph wire, where it was uttering its more common call. A red-shafted flicker was noted as it flew from one Eucalyptus tree to another.

Vegetation present on this west facing slope included chiefly small annual grasses, but scattered about were Coulter Pine (P. coulteri), Ceanothus sp., Quercus chrysolepis, Baccharis. Mammal sign was abundant. Microtus & Citellus burrows and runways abounded. Two Neotoma fuscipes nests were found among boulders. Fecal pellets of Peromyscus, Neotoma, Microtus, Citellus were identified. Burrows seen, which were intermediate in size between those made by Microtus and those made by Citellus may have been constructed by Dipodomys; these burrows were abundant. One Citellus b. beeboyi was heard calling. Old Squirrel burrows were being used by smaller animals, for small holes were often found at or near the bottom of partially filled in squirrel burrows. I set out 48 mouse traps at approximately 10 paces spacing on this hillside. Found in traps this morning: 7 Peromyscus m. gambeli (5 discarded); 5 L.

The purposes of the trip, as regards mammal studies, were twofold. First, a larger series of Dipodomys h. was desired. Second, it was desired to determine, if possible, if a particular area which had been trapped fairly extensively about a month ago had become "re-infected" with Peromyscus. On Feb. 16, an area on a south-west facing slope was trapped well. Numerous Peromyscus mani- culatus and fewer Microtus californicus and Reithrodonmys megalotis were removed at that time. Now, would the an equivalent number of the same species be obtained on Mar. 22, or would other "less-forward" species be obtained - since Peromyscus perhaps would not "fill up the traps". The degree of error, of course, would be large considering the time lapse, the relatively small number of traps out, and the non-uniform traps - live traps were used on Mar. 22. 20 "Benson" live traps placed in the above area yielded the following: 2 Peromyscus maniculatus, 2 Reithrodonmys, 2 Desognathus californicus, and 1 Microtus californicus.

Mar. 22, The Peromyscus were relatively less abundant, & new species, Perognathus, was trapped - in comparison with catch of Feb. 16. However, perhaps the pocket mice were not out of hibernation in February. About 70 "standard" mouse traps were set out as a line separate from the live trap line. These guillotine traps were placed on an average of 15 paces apart along the top of and sweet brow of a hill. The ground was rocky; soil layer very thin - probably not over 4 inches on the average. Vegetation present: chiefly annualse (grasses, [Eschscholtzia]); scattered clumps of Artemesia ; California Bay. (Umbellularia) and canyon live oak (Quercus chrysolepis) and poison oak (Rhus diversiloba) in side canyons. Mammal sign was abundant. This morning I found the following animals in my traps: 13 Peromyscus m. gambelli, 3 Peromyscus t. gilberti, 1 Microtus c. californicus, 8 Dipodomys heermanni and 1 ? horned lark (Otocoris alpestris)

April 24, at 4 P.M. Left Berkeley in company with Miss. Mary Erickson. Drove through Tracy and Stockton; reached San Andreas about 9 P.M. Had stopped for 40 min. in Stockton for dinner. Since we were in a hurry, we noticed few birds along the road. The usual red winged blackbirds, meadow larks, California shrikes, English sparrows, linnets were seen intermittently after we passed through the Livermore hills; dark put an end to further observation. On reaching San Andreas, we stopped at Pac. Tel. & Tel. office to find address of Mr. Wiley, who signed the last letter to Dr. Grinnell regarding the "jay hunt" as "Secretary of the Calaveras County Sportsmen Association". This title, I have reason to believe was adopted for the express purpose of making the "jay shoot" personnel sound like a real organized body. Sans "jay shoot", sans title, I believe. Had no trouble locating Wiley, so called on him immediately. He extended the "glad hand" readily to us and was quite pleasant. We, in turn, expressed our appreciation for the favor granted us, namely, allowing us to be at hand for the shoot.

April 24, The following are important points supplied by Wiley during our conversation with him: The hunt is county wide; anyone can take part who lives in county. (He didn't state that the hunting for jays must be limited to the county alone, but intimated as much indirectly). Those who desire to hunt are divided into two teams. A hunter doesn't know this year, of which team he will be a member until the day of the shoot. Heretofore the teams have been formed at least a day before the shoot. The hunts are an annual or semi-annual affair, most often the former. About 800 birds were killed last year. As many as 1200 or 1500 have been killed during a previous year. All jays and hawks are brought in for the counting. Hawks may be worth 5 points [jay = 1 point]. Cats (which are abundant here in federal state) should be worth at least 5 points; they do more damage to birds than do jays. After the counting of the birds, a barbecue to be held this year at Cafe. A dinner followed the hunt & counting during each previous year. The loading side pays for food bill. Beef & lamb to

April, 1936 San Andreas, Calaveras Co., Calif. April 24, cooked be [illegible] this year. Doesn't believe "shoots" on number cut down of jays - seems to be as many to kill next year. [However, as many as 1200 or 1500 have been killed before! Note bog this year!] The most benefit comes from the pleasure derived from hunting and from the mixer at the barbeque. Other birds are often mistaken for jays: yellowhammers [= red shafted flicker] sometimes flies like a jay; bush robin [= brown towhee?] have profile in tree like a jay; woodpeckers (reddish-black on belly; black back) [= Lewis woodpecker. Chicken hawks (the small low-flying hawks) are of more harm to quail and other birds than are the big circling hawks. All count in this contest, though. Wiley's "contributions" continue: Has seen [past completed action of verb or progressive action?] quail nests destroyed by jays. A friend of his also saw a jay fly from chicken roost with a hen's egg on its bill. These hawk shoots might go too far, though, he said. This predator -> prey business is complicated. Maybe if the jays are destroyed other worse "things" will take their place. End of Wiley for the moment.

sopeo, 1934 San Andreas, Colavers Co., Calif. April 24, Wiley seems to have been well educated. He is at present a mining engineer. The diagrammatic drawl he uses in speech follows naturally from contact with the people of this region. After conversing with Wiley, M. Erickson & I returned to main street of town. Took the last two rooms in Hotel Trent - the only hotel in town. April 25, San Andreas is a town of about 15 or twenty small stores (including filling stations & garages. Though this is Saturday, during the short time we have been in town the streets have been almost deserted. The town lies in a small valley near the N. Fork of Colavera River, a river of about 10 C.F.S. now at the bridge just south of town. The hills about the place are gentle and rolling, in slope and are covered with vegetation of the following main kinds: 1. Avena - wild oats abound. 2. P. saliniana - digger pine. 3. M. Arctostaphylus - manzanita. 4. Scrub oak.

The country is pretty much the same as regards floral + faunal associations + zonation, as far south A least as Valley Spring (10 mi. from San Andreas), and as far north as Mountain Ranch, 12 mi. N E of San Andreas. At these places begins to Upper Sonoran give way to Lower Sonoran + Transition. At 2 mi. S/W of Mountain sugar pines and yellow pines were first noted. Made X census of a region about 3 mi. W of San Andreas and about 1/2 mi. from the N. Fork of Calaveras R. On the cooler north and east facing slopes, scrub oak (Q. wislizenii), digger pine, (some) poison oak and manzanita were the dominant perennials; wild oat was the dominant annual. On the south and west facing slopes, chaparel is dominant; very few annuals are present, and are on every instance where present. I worked over the north + east-facing slopes entirely. Jays would not be abundant in pure chaparrel stands! When larks (colubrinae) were heard calling from these slopes.

Cooper, 1936 San Andreas, Calaveras Co., Calif. April 25 For list of the birds seen, refer to the census sheet of the aforementioned locality & for the above date. Cistellus b. beebeji was the only mammal seen. Our plans for census taking, is in brief as follows: one census (each person taking a separate census over a separate area) south of town - where more Calif. jays would perhaps be found; one in the vicinity of San Andreas- so that we could check on those hunters who were too lazy to leave their back yards; one census north of town approaching or in the lower Transition Zone - where more Stellar jays might be found. The first census has been briefly described. The second census covered about the same distance as the first (2 mi.) and, was 1/hrs. 10 min. in duration and took place about 10 mi. N.E. of San Andreas and 2 mi. W of Mountain Ranch. Here the Transition influence was well indicated by sugar & yellow pines. They were mixed with Digger pines and were.

October, 1936 San Andreas, Calaveras Co., Calif. April 25, Dominant as to numbers on north facing slopes. Because my route as outlined carried me through so much chaparral, where the bird population was comparatively low and the creatures difficult to see, the total number of birds seen here was much lower than at the locality S. of San Andreas. Less than 1/5 the number of jays were seen. See census sheet -- Returned to San Andreas at 1 P.M. for lunch. Will take the third census here from 5 P.M. to 7 P.M. today. On Monday, we will catch this region the first thing in the morning, 5 A.M. - 7 P.M. At the cafe more information re. "jay hunt" obtained. Hunts have been held for at least 11 yrs. The "proprietress" of the cafe contended "I don't think its right to kill them, even if they are vermin'. They may kill a few chickens & quail but they were put here for a purpose." - a teleological viewpoint ? Riley informed us this P.M. that the jay shoot had been held intermittently ever since he was a boy. [Age now = + 35 yrs].

Cooper, 1936 San Andreas, Calaveras Co., Calif. April 25, Information from Schwosser continues: Evidence of quail destruction by jays— young quail seen eaten by jays — only brains of young eaten. Also eat chicken eggs. The jay popula- tion seems to be about the same now as before. The reason for the decrease in numbers of jays brought in is that the interest in the shoot has lagged and the men are lazier. Quail populations are not influenced to a great extent, if any. Rather the decrease is due to (1) great increase of hunters; (2) dry seasons extremely during the last few years, resulting in decrease in food & water supply; (3) late rains in the years, resulting in killing of warm eggs during incubation period; (4) removal of cover forest caused by recent extensive fires during past few years. Schwosser said there was considerable poaching carried out here. As many as at a time 15-25 deer have been taken out of the region out of season. It is a commercial proposition; the deer are marked for Stockton or the Bay cities. The last few loads went out under & loads of Xmas trees. One lodge in Oakland — Elks or Moose — consumed 25 head. The sportsmen here resent the instruction

Looper, 1936 San Andreas, Calaveras Co., Calif. April 25, Took a third census today around the eastern and southeastern periphery of the town of San Andreas. The zoation, floral + faunal associa- tion is the same as the locality 3 mi. W of San Andreas where the first census was taken. To date, have recorded on census sheets a total of 79 days for approximately 7 miles covered. They are wary + hard to see in dense oak stands. Contacted Mr. Schroverer, the supt. of school and evidently president ? of the Calaveras Co. sportsmen club. Secured the following information from him: Quail rearing pens are being built on W.P.A. funds. Birds can thus be secured from the state Fish & Game Commission held until large enough to turn loose. All quail introduced there in the past have been placed on "game reserves," which are privately-owned parcels of land on which no hunting is allowed. Hungarian partridge and wild turkey have been introduced, but haven't proved successful. The turkeys were placed on a rich man's estate - no hunting ever allowed. They had to be removed from this property because they roosted on the rich man's houses' porch; were taken down to Angels Camp, where roosted in a barn until we killed off 1 by 1, as turkey meat was desired by the "sportsmen".

Looper, 1936 San Andreas, Calaveras Co., Calif. April 25, of outside poachers - that is, those from out of the County - and Commercial hunters. The average number of men for each jay shoot is reported to be 18 or 20. The Calif. perside jays are considered by some residents worse on quail and chickens than the "mountain jays". April 26, The attitudes assumed by the several male citizens of the town are diverse in nature. This morning, some were up at dawn rarin' to go. Others, now at 8 o'clock, are lazily wandering forth. Some men who are not to shoot contend: (1) Why shoot blue jays. (2) There are more profitable things to do than hunt jays. (3) I have work to do. (4) Too old for hunting [young fellows] (5) Too hard work. 2: P.M. Have just returned from trip (reconnaissance) northeast to Mountain Ranches Sheep Ranch thence southwest to Murphy and Angels Camp. As the result of this trip, the "jay-huntable" territory is now known, in general. For details see following page. Angels Camp seemed little interested in the jay hunt. The inhabitants there were concerned with a baseball game.

San Andreas, Calaveras Co., Calif. April 26, I believe this jay hunt concerns, for the most part, the inhabitants of San Andreas. At approximately 3 mi. N of San Murphy, 30 min. was spent at an area in lower Transition - mixed Transition + Upper Ponderosan yellow pine, tanbark oak, and indicators: [illegible] incense cedar mixed with digger pine, Q. wisligenii (?) and hard chaparral. In the chaparral, I noted: Bewick wren, wren tit, Calif. quail, and spotted towhee. On pines and tanbark oak, these birds were seen: Cassin solitary vireo, blackthroated gray warbler, western robin, chipping sparrow, Calif. woodpecker, and stellar jay (1 only). Striped skunk (Droppings were seen here. Sketch showing probable area covered by jay shoot. Concentrated shooting along ooooo. At lunch in Angel Camp.

Apr, 1936 San Andreas, Colveras Co., Calif. April 26, in Colveras Co. The region north east of a line running between Murphy and Mountain Ranch (=5 El Dorado on some maps) is too mountainous and vegetation covered to warrant hunting there. Total potential "jay-hunt-able" area in County = approximately 500 sqmi. Concentrated hunting: between San Andreas and Valley Springs. Everyone seemed to enjoy themselves at the barbecue. Plenty of food and beer and a guitar soon had everybody in good "spirits". Birds were counted before food was issued. One person counted, another checked amounts on a chart. Jays = 1 point; hawks = 3 points. Birds brought in are as follows: jays = 612; red-tailed hawk = 1; Sharp-shinned hawk = 1; Sparrow hawks = 3; horned owl = 1; (Calif.) shrike = 1. Total = 627 pts. 34 men shot in the contest, 12 from Angel City and 22 from San Andreas. Ammunition purchased for shoot in San Andreas = 58 boxes (12-16, 20ga). Cost of ammunition = $35.00 in San Andreas, $1.00 per sportsman was contributed toward cost of barbecue. 76 birds was highest individual score. 1 bird = lowest score. Mean = approx. 20-30.

April 26, 21 men in San Andreas purchased 58 boxes of shells for $35.00. Of the 12 men from Angels Camp purchased in equivalent proportions, 33 boxes would be purchased and for about $20.00 (computation = $19.80). Or a total of 91 boxes purchased for $55.00. How many of these shells were not used is not known. The number of birds killed last year mounts! The owner of the drug store in San Andreas reported 2000 birds killed last year! The hunter who killed the largest number of birds this year (76) reported he had hunted on "game refuges" [= quail & deer refuge?]. Further evidence that interest in these jay shoots is waning was shown by the fact that approximately as many names of men who did not shoot were on the list compiled as those who did shoot. Some men evidently shot (hunted) all day (5 A.M. to 5 P.M.). Others must have confined their hunting time to a few hours. Birds were brought in to the counting place in burlap sacks, hunting coats, paper bags or any other container at hand.

Cooper, 1936 San Andreas, Calaveras Co., Calif. April 26, Conversation with one of the sides yielded the following interesting side-lights: Barish robins (= brown towhee) not brought in, but often? shot, mistaken for jay. Jay hunts have been held here for 40 yrs. Usually held in fall of year when few leaves on trees. Seems to be more jays this year than before. Some jays have migrated now [= paired off & nesting, so less conspicuous]. Distribution tion of poisoned grain for ground squirrels leads to death of more quail than any other thing. As soon as cattle or sheep taken out of a pasture, poisoned barley distributed. This grain even kills deer. --- A few days ago 3 burlop bags of cats were brought out from Stockton to a place near here. Were to be turned loose. Herald cats are "big" enemies of quail. A few quail (± 8) were seen in a covey. All others were in pairs. Jays were in flocks or in pairs, approximately equally divided. However, perhaps the jays had paired off and were merely seen in larger groups because they where, driven there as I advanced thru forest.

San Andreas, Calaveras Co., Calif. April 27, Three censuses were taken today. Two were over the same routes as on Apr. 25, namely, 3 mi. SW San Andreas and at San Andreas. The third was taken on a game refuge where it was believed the "high scoring hunter" had collected. The results of the censuses yield little conclusive information. No marked reduction in jay population was noted. The area covered by the censuses was too small in relation to the potential "jay-hunttable" territory which might have been covered by the hunters. The limit of error is too great. Hunting possibly wasn't done on the areas covered by the censuses. Since no quail nests were found, an examination of the jay stomachs probably will yield little information on quail predation by the jays unless on adult quail. Certainly, no young quail are hatched, even if eggs are laid. Only the insect-eating birds (such as flycatchers, phoebes, and warblers) were noted as still unpaired. For the most part, other birds were seen in pairs. Of course, the insect-eaters could have been paired

Cooper, 1936 San Andreas, Calaveras Co., Calif. April 27. off and the mate not seen. However, in the light of the large number of single birds of this nature observed, this seems unlikely. Digger ground squirrels were obser- ved, but not in abundance. Not over 15 were seen in the entire area. Three jackrabbits and 1 brush rabbit (or cottontail were noted. A lark sparrow's nest (with five eggs) was collected from an open grass- covered meadow. The nest was on the ground in the dense growth of wild oats that abounds there in the digger pine - black oak belt. The jays nest collected was secured by Mr. Wiley and donated to us. Three eggs were in it. Another nest was found, but only the three eggs from it were saved. Wiley also reported the finding of a red-tailed hawk's nest with from 4 to six downy nestlings in it. It was left unmolested. Left San Andreas at 3 P.M. and arrived in Berkeley at 6:30 P.M. The further attention. 627 birds were put in cold storage pending.

Left old camp on Truckee R. at 8:15 A.M., drove to Reno where went to P.O., and restocked with groceries; left Reno at 10:45, drove north along Pyramid Lake, following the S.P. railroad route (to Susanville) to this locality. Set out 10 mouse traps, 10 paces apart, in Artemisia on course sand. July 4, Caught in traps: 4 Perognathus longimembris, 1 Microdipodops, 1 Dipodomys merriami, and 1 Dipodomys microps. Set out 15 mouse traps and 2 rat traps along rocky outcroppings and adjoining rocky soil. July 5, Took in traps: 2 Neotoma lepida, 2 Perognathus longimembris, 3 Brachymys saintitus. All were put up into study skins. July 7, Moved camp yesterday to Smoke Creek, 3900 ft., 9 mi. east of Calif. state line, Washoe Co., Nev.

Hooper, 1936 Smoke Cr., 3900 ft., 7 mi. & Calif. line, Washoe Co., Nev. July 7, belonging to a Mr. Jenkins (?). Along the creek bottomlands, cottonwood, willow and other riparian indicators are found. Ad- joining the stream association (with the occasional marshy lands and small pools) is found an Artemesia - Chrysopthamus association. In this deserted house were found abundant signs of wood rats. Droppings abound on the floors, on tables, and rafters. One nest was found in an old bureau. The bottom section of the bureau was full of the following materials: cottonwood leaves , cow of horse bones, pieces of wood, a coyote skull, and other miscellaneous bones. No tunnels or cavities could be found in this mass of material. It seemed to be merely an "accumulation" alone - resulting from and probably satisfying partially the instinct to collect or accumulate "odd" articles. Per- haps the cottonwood leaves and stems would be used later on (winter?) for food. In the drawer just above this accumulation was the nest proper. It measured: 8 in. from outer rim to outer rim; 4 1/2 ins from inside rim to rim; and about 4 in. high. It was free from fecal matter and probably

Found in traps this morning: 1 Ammospermophilus, 3 Dipodomys microps, 2 D. ordii, 3 Microdipodops, 3 Peromyscus maniculatus, 1 Reithrodonmys megalois, 1 Perognathus parvus. Set 2 rat traps in the ranch house where we camp. Caught this morning 1 Neotoma cinerea. July 9, Took 1 more Neotoma cinerea from 1 of 2 rat traps set in this old cabin. These rats are exceedingly abundant here. They inhabit this house, outlying outhouses, old cottonwood stumps, rock piles, and piles of debris (which, for the most part, have been formed during high water periods of the creek and were not, probably, built by the rats). At night they can be heard climbing about in trees and running about on the dry.

Last night Russell shot one out of a cottonwood near the house. I have tight heard them in these trees at least 15 ft. above the ground and probably higher - I could not definitely locate these latter, higher ones. Sign is exceedingly abundant along the creek. As the result of a light shower last night there is now enough connect water in the creek to several of the almost pools (down as far as the automobile bridge near the ranch house); they were separated by dry land before the rain. It is now cloudy and overcast (4:30 P.M.), perhaps promising more showers tonight. The strong wind which has blown daily after approx- mately 9 A.M. (until 7 P.M) has been con- spicuously absent today. Collected a garter snake in the grass beside one of the pools along the bed of Smoke Cr. July 10, Collected a garter snake near the same place where the one, collected yesterday. Shot a in spotted towhee from a willow thicket near the creek bottom. Collected a lazuli bunting from a bush near a flat gravelled area, 100 yds.

Left Smoke Cr. at 3:40 P.M., drove via Round Hole to Gerlach; secured food, water, gas there; left at about 6 P.M., drove north along the east side of the Granite Mts. to Rock Cr., then up (westward) Rock Cr. to our present camp. Immediate area about camp - which is beside the creek - includes the following plants: along the creek = alder, aspen, wild rose, and birch; on the surrounding slopes = Artemisia alba? & dry grass; on south slope = Artemisia tridentata, A. albus? and an occasional Arctostaphylos and wild rose (in shaded draws). This morning I walked to the top of and along the ridge to the south of camp. Reached an altitude about 500 ft. higher than camp. Saw woodrat sign among rocky outcrops. Shot a yellow-bellied racer on a rocky area, near top of ridge. Saw meadow-lark

Hooper, 1936 Rock Cr., 5000 ft., Granite mts. Washoe Co., Nev. July 11, green-tailed towhee, mourning dove, yellow warblers. Saw no chipmunks, though they should be here - the country "looks good". I could see no conifers - Juniper or pinyon pines - up to an approx. altitude of 7000 ft. July 12, Set out 30 mouse traps last night along the edge of the creek for Sorex palustris and Microtus mordax. Part (about 1/3) of the area trapped was covered with aspen, birch and alder, under which was a sparse growth of grass. The other 2/3 of this area the trees had been burned off; the Artemisia was, there, almost to the water's edge - having advanced into the burned area. No traps were set about 100 yds. from the stream on a south- facing slope and under Artemisia clumps and around rock piles (talus). Caught this morning: 8 Perognathus parvus and 1 Peromyscus maniculatus. Three of the pocket mice were caught at the edge of the water (not over 5 in. away) in the burned-over area. The other pocket mice were trapped on the hillside under Artemesia, the Peromyscus in a talus. Four specimens (all Perognathus) were sent.

Several small springs+tributaries feed the stream. At each one of these water sources older, birch, and aspen grow in thick stands. These trees also occur all along the main creek. At about 5300 ft. we saw ± 8 jays of the California jay general shot one bird (jay) but could not find it in the dense brush. Shot a Callo- spermophilus from rocks along the creek at approximate altitude 6400 ft. At 7000 ft., collected a Bufo in marshy ground in an Aspen thicket. In this same thicket we jumped a deer but could not get a good shot. From boulders near the creek at 6600, collected a Eutamia minimus.

Their "bark" or call resembles that of Citellus feldingi of the Sierra Nevada. In the Artemesia on the slopes surround- ing the meadow chipmunks could be heard "chipping" and could be seen occasionally. From about 6200 ft. on up to the meadow, Callospermopsis lut., Eutamias minimus were found; seeming to increase in abundance as altitude increased (along the creek). Citellus were observed at about 6200 ft. Shot two squirrels (Citellus) on the meadow. Returned toward camp by same route to about 6400 ft. level; then turned westward over dry ridges to cover other aspen thickets. Jumped two fawns and one doe (?). Saw the doe just as she was disappearing over a ridge about 150 yds. away. Noted that the rump region was markedly white. Deer sign was abundant in each alder thicket searched. Russell set two gopher sets at about 6000 ft. Left them for 4 hours but caught no gophers.

An artesian well there supplied water to grass and small patches of alfalfa. Could find no gopher workings here but did collect some fish (Catostomus or Pantosteus?) from the streams leading from the well+spring. Next we (Hall & I) drove about 1½ mi. S of our camp (1 mi. W Hausen) to an old sheep ranch. No gophers were found to be working here. Drove back to Duck Valley, made one shot in a hay field. Shot a woodrat from On July 16 packed up all equipment, drove into Calif. At the inspection station near Hausen, drove to Cedarville where re-stocked with food+gas and ate lunch.

Hooper, 1986. 12 Mi. Cr., 5300 ft., ½ mi. E Calif. line, Washoe Co., Nev. July 17, “down creek” One half a mile (approx.) from camp, I found a meadow about 200 yds. long. Water from the creek is diverted out over the meadow. Near the western edge of this meadow, about 60 ft. from rocky slopes a woodchuck was found. It was lying beside a small ditch containing water and was so well concealed by grass that I was within 15 ft. of him before I saw him. I shot both the 12 ga. (8 ch.) and 4/0 ga. (12 ch.) but the animal succeed ed in reaching its home in a tulus slope. Shot a sage hen in the Artemisia near the creek. Saw a young rattlesnake. ½ mi. N Vga, 6000 ft., Washoe Co., Nev.

Hooper, 1936 Berkeley, Alameda Co., Calif. Oct. 25, Last night Jack C. von Bloeker and myself set out 100 "Benson-Russell" live mouse traps in the Salicornia on Richmond salt marshes. More specifically, the locality was Imi. E mouth San Pablo Cr., salt marshes, Contra Costa Co., Calif. The area trapped was approximately 2 feet above high tide level. Traps were placed about 6 feet apart. Found in traps this morning: 1 Microtus c. paludicola, 4 Reithrodontomys m. longicaudus, 6 Mus musculus.

Bishop, Inyo Co., Calif. Jan. 6, Since Sunday, Dec. 27, 1936, the ground has been covered with snow. The first snow fell on this date in December - at the end of this fall (about Dec. 30) approximately 2ft. of snow on the level was present. All low-lying vegetation-even Artemisia tridentata - was covered. During the period Dec. 27-Dec. 31 I made several trips afield, hiking about 2 1/2 mi. to the east, south and north of Bishop. Immediately after the snowfall no tracks of mammals were seen. However, the following day (2 days succeeding the cessation of snowfall) tracks were abundant in the open fields and along road- and canal-sides. Jackrabbit and cottontail tracks were most numerous, concentrated along ditch banks where vegetation was exposed. Smaller tracks I believed to be those of Peromyscus and Reithrodon tonyx were seen to lead from clump to clump and around almost each clump of the composite which abounds here. Most of these led ultimately to the dried head of these plants. Here was a supply of food that could not be reached when snow was not on the ground.

Hooper, 1937 Bishop, Inyo Co., Calif. Jan. 6, Position of Previous to the snow only those seeds which fell to the ground from the upper flowers were available to the mice. Now the "walkable substrate" was on a level with the dried uppermost dried flowers. I noted tracks which I believed to be made by a fox but am not certain. The sweet odor of a skunk was detected in the slight breeze at about 4 P.M. Birds noted included: Savannah Sparrows (abundant, in flocks, along streams in the willows and in clumps of composites in the open fields); Green- elm boaked goldfinch (1 seen south of Bishop feeding on a composite along the highway); Maggie (flock of 4 or 5 seen each time I "went afield" in open fields or trees); bird Marsh Hawk (one, seen at three different places - each time flying low - +6 ft. over open fields); Sparrow hawk (1 observed perched atop a poplar tree near town); Bush-tits (flock of +8 feeding in pear and apple trees); Red-shafted flicker (at least three seen or heard in trees - not seen feeding); (house)? a Wren (in willow thickets along a stream); Robin (2 seen in trees about town); Brewer Blackbird (flocks of +5 seen - one bird sought

The seed-eating birds certainly predomi- nate, both kinds and number of indivi- duals. At such crucial times as these, if not all insects must be destroyed; insecti- vorous birds must consequently decrease or migrate. Seed eating birds seem to have a better chance for survival. Yesterday, Jan. 5, I saw a Western Wood ? Peewee? out in locust and poplar trees in the back yard of our house. It perched at the branches as if hunting for food—the Bush Tits seemed to have been successful here a few days ago—flew up to the eaves of the house, but was never seen to peck (for food).

E mouth of San Pablo Cr., Contra Costa Co., Calif. Bait used was oatmeal. Weather conditions: cold, +10 m.p.h. north wind; snow on hills in Marin Co. and on hills back of Berkeley Hills. This locality is the same place visited on Oct. 25, 1936. This morning I found the Delusion traps untouched. In the govt. mouse traps were: 3 Reithrodontomy, 4 Microtus, 1 Sorex vagrans, and 3 Mus musculus, and 1 Marsh song sparrow. The 3 house mice were discarded and the song sparrow given to Mr. W. B. Davis. The remaining 10 specimens were put up by myself. Jan. 16, last night, Drove to Melrose Marsh about 1/2 mi. E Bay Farm Island and set out 24 snap traps, 6 Delusion traps, and 20 "can" live traps. The weather: cloudy, rained just after put the traps out. The Salicornia in which I sat was for the most part dead, probably

One live harvested mouse was caught in a can live trap. The only other live trap found containing a specimen was a "can" trap— contained a field house mouse. The rest of the animals were captured in snap traps (got8. mouse traps). The water (rain) on the can traps was frozen this morning. Feb. 15, Trapped at the locality "Salt marshes, giant, Contra Costa Co., Calif. last night. In the Salicornia and sedge I set out 50 got8. mouse traps, 25 "Benson" live traps and 6 can live traps. These were placed for the most part on high ground above the high tide limit. Trails and small mammal signs are abundant here. When collecting my traps this morning at 8 PM. I saw at least three small mammals running under the grass. Some of the burrows, even up on the high ground, were still almost full of water, probably a remainder of the several recent, hard rains. The soil is still saturated even on gentle slopes. Last rain was

Hooper, 1937 Berkeley, Alameda Co., Calif. Feb. 15, on the night of Feb. 13. The catch this morning was: 2 Mus musculus - 1 in "Benson" livetraps; 1 in snare trap; 3 Microtus californicus - in gosh traps; 4 Reithrodontomys megalotis - 1 in can trap, 3 in gosh traps. The two house mice were discarded, the live harvest mouse confined to a cage, and the remainder made into study skins. All of the mammals preserved were trapped in California. No embryos were found, though the testicles were enlarged in one Reithrodontomys. 1 mi.

Feb. 28, on occasional growth of Typha in low-lying marshy places (this growth indicating that the water is not too saline - Pacheco Creek probably supplying some fresh water) and Spartina on the higher ridges. The Salicornia is quite brown and superficially dead; however, near the bases of many plants new growth is appearing. On the south side of the S.P.S.F. & New Orleans line-tracks and at places on the north side - particularly along slough channels, a coating of oil covers soil and vegetation. Here, as at Giant, mammal sign is abundant - Microtus run- ways, droppings of meadow mice, harvest mice, some carnivore drop- pings which contained a very high percentage of bones and fur of small mammals. Steel traps were found set for raccoon and mink. The owner of the traps stopped this morning when we were collecting our mouse traps; he reported he had taken 12 mink from that region during the past year.

Marsh wren, song sparrows, meadowlarks, Brewer Blackbirds were abundant, all "singing" in the evening and morning. I set out 35 "Benson" live traps and 67 snap traps at an averagedist. of 10 paces apart in the Salicornia and along the border of a stand of Baccharis (with Salicornia immediately adjoining). In Typha and along a slough bank 13 snap traps were set at an av. dist. of 8 paces. All were baited with oatmeal. Found this morning: In live traps: 1 Mus musculus. In snap traps placed in Salicornia: 9 Neithrodonmys, 1 Sorex, 2 Microtus, 2 Mus musculus. In snap traps in Typha: 2 Microtus. All but 2 house mice are saved as specimens. We ate dinner in Martinez, drove back to the marshes to spend the night. After collecting our traps this morning we drove back to Berkeley - reached here about at 10 A.M.

Hooper, 1937 Berkeley, Alameda Co., Calif. Mar. 7, Yesterday afternoon, in company with D.H. Johnson and F.G. Palmer in Johnson's car, drove out through Walnut Creek and Pittsburg to the region between Antioch and Mt. Diablo. The purpose of the trip was to find small pocket mice (Perognathus inornatus), remains of which have been found in Barn owl pellets taken from a locality about 3 mi. S Antioch. We searched for likely looking ground (sandy, un-grazed land) but could find none. We finally set out traps at the locality 2 1/2 mi. S Antioch, 250 ft., Contra Costa Co. I put out 20 mouse traps on the crest of a grass-covered hill. Mammal sign was not abundant. Gopher diggings were found. Large, adult (evidently) Ground squirrels were seen running about on the south-facing slope. Traps were set at an average distance of 3 paces apart near old ground squirrel holes (which were evidently being used by some other kind of animal), & near holes which looked suspiciously like kangaroo rat diggings, and around the border of a concavity (probably an old gravel pit or fossil digging - since large limestone outcrops occurred there). In these traps I found this morning

Hooper, 1937 Berkeley, Alameda Co., Calif. Mar. 7, 1 Peromyscus maniculatus. It was discarded after setting out traps here we drove back toward Martinez to the locality [illegible]. Antioch 5 Norton, 100 ft., Contra Costa Co. Here I set out 48 mouse traps in wheat stubble along a stream running thru the field. Ground squirrels were heard calling and numerous burrows noted. Found this morning: 21 Peromyscus maniculatus (10♂, 10♀). Saved 3 females and 2 males. I forgot to mention that sheep were grazing over the hillside where the first group of traps were set. Most of the traps were sprung. Returned to Berkeley this A.M. via Somersville, Nortonville and Walnut Cr. Mar. 10, 1937 While up in the Berkeley Hills yesterday looking for a suitable area for the Zoo. 1/3 Microtus study, Fred Test and I found 1 Gerhonotus and several Batrachosaps under pine logs in grass at the top of Dwight Way Hill. The lizard was partly hidden by the bark of the log was cold, sluggish and seeming in a state of semitorpor.

Hooper, 1937 Inverness, 100 ft., Marin Co., Calif. Mar. 27, In company with Mrs Hooper and my brother Frank Hooper, left Berkeley Mar. 25 at about 11 A.M. and drove to Inverness for a 3 day + vacation and collecting trip. En route noted: California gulls and Ring- billed gulls riding the air currents over the ferry boat; 3 [illegible] grebes riding on and diving in the water of the bay; a sparrow hawk on telephone wire along road near Fairfax; 4 deer in redwood grove along stream near San Geronimo; numerous crows in flocks and two's from Ross Valley to Inverness; many gulls (+ 35) foraging in fresh water marsh at mouth of Olewa Cr.; turkey cultures near Inverness. We are now in Smyners Cabin located about on the NW facing slope of the 100 ft. above the canyon which opens out (mouth) at the stores in Inverness. The vege- tation here: Calif. Bay, Pinus radiata, [illegible] sp.?, madrone, buckeye, elder, sword fern (Polystichum aculeatum). This vegetation is present on both north west and south east slopes of this canyon. Higher up toward Mt. Vision a more pure stand of P. muricata and [illegible] sp is found - as well as of alder.

Hooper, 1937 Drwerness, 100 ft., Marin Co., Calif. Mar. 27, Night before last (Mar. 25) set out traps at the locality Point Reyes Station, salt marsh. This locality, more exactly, is about 1/2 mi. N NW Pt. Reyes Station at the head of Tomales Bay - on the N side of this Bay. 35 traps were set in Salicornia mostly in Microtus runways not over 100 ft. from the old San Francisco and Cazadero Railroad bed. Found in those traps: 7 Microtus. Set 1/5 mouse and 1 cat trap on the hillside east of the marsh in thimbleberry, Acrostichum sword fern, Baccharis. Saw what may have been Aplodontia burrows in sword fern clumps. Caught nothing in the brush. Made 1 gophers set; set not disturbed when taken up the next morning. Also set 25 mouse traps the same evening on the west side of the Bay (Tomales) about opposite (as re. latitude) the locality on the east side. These traps were set in sedge ? (arrow grass?) and in Salicornia. Caught here 1 Microtus and 5 Peromyscus (3 juv.) - all in Salicornia.

Hooper, 1937 Inverness, 100 ft., Marin Co., Calif. Mar. 27 Last nite I drove out the road toward Pt. Reyes to just the other side (West) of the summit. The locality, Pt. Reyes road, 2 mi. NW Inverness, is about to canyon 1/2 mi. down toward the ocean from where the old "Norman Cabin, 3 mi. Pt Inverness" locality was -- see W.T. Taylor, J. Fimell, C.F. Camp, etc., 1912. Set 50 mouse traps about 6 faces apart (av.) in the meadow, soggy, wet, arrow; edge? under second fern and grass. The ground is very wet, most of it covered with 1" or more of water; only occasional places out of water -- and these soggy. Caught this morning in the above situation: 1 Microtus (with 4 embryos) and 3 Sorex. One shrew was so badly eaten by some animal that only the skull could be saved. Frank put out 20 traps near our house -- under fern clumps, at the base of bay and alder trees. He found this morning 4 Peromyscus maniculatus (3 juv.).

Inverness, 100 ft., Marin Co., Calif. Mar. 27, Noted a Ringfisher sitting on a telephone line at the mouth of one of the canyons (whose bottom was a small stream - pond at mouth) about 3/4 mi. N. Inverness; a great blue heron near this locality but in the salt water tidelands. Mar. 28, Went north of Pt. Reyes Station last night to the locality Grand Canyon, 2 mi. N. Pt. Reyes Station and Bivoloé, 2 mi. N. Pt. Reyes Station. Grand Canyon is one of the several wooded canyons which interrupts the even, rolling hills on the north side of Tomales Bay. Bivoloé is (or rather was) a settlement located at the mouth of Grand Canyon. Only an old road house or "liquor joint" now marks the spot, as regards houses. In the canyon the following plants grow: poison oak, Calif. bay, willow (along stream), Baccharis, and grass - the last filling in the spaces between chaparral or trees. This vegetation is on both slopes, but more dense on the NW-facing than on the SE-facing. A stream now flows in the bottom of the canyon, however.

Hooper, 1937 Inverness, Marin Co., Calif. Mar. 28, it probably dries up in the summer time, since its drainage area is so small. Noted red-tailed hawks (2) and turkey vultures soaring over the canyon. Also saw in the canyon: 1 Western Robin (on telephone line); 1 Soren-tit (and heard several in dense poison oak and Baccharis), 1 late-summer warbler - heard several? in Calif. bay trees. Numerous wood rat houses were noted on SE-facing slope in poison oak and Calif. bay. I set 4-5 mouse traps on SE-facing slope under poison oak, bay, and Baccharis, and 2 rat traps (1 up in bay tree and 1 in nest). Caught: 1 wood rat and 3 meadow mice. At the mouth of the canyon near Bivolar [see U. S. G. S. sheet, edition 1918] in Salicornia about 15 ft. from a chaparral-covered hillside, and ± 10 ft. from a slough on the other side I put out 35 traps. Caught this morning 1 Reithrodontomya and 2 Microtus. In 2 gopher sets made at Bivolar on a grassy hillside I took 1 Thomomys. In the hole in which taken the animal was captured, it was found that the posterior end was facing down the burrow. Yet the hole was well plugged with dirt - it was open.

Hooper, 1937 Druxness, 100 ft., Marin Co., Calif. Mar. 28, when the trap was set, at the head of Tomales Bay at mouth of Olmos Cr. more gulls were seen feeding on ground flooded to a depth of about 2 in. Among the smaller Calif. and ring-billed gulls was one glaucus or glaucus-winged gull. It was much larger than the others, had a large bill (black, except perhaps for basal half or third); feet and legs not seen; plumage entirely white except for slight washing of rusky over breast and lining of wing. Berkeley, Alameda Co., Calif. after putting up specimens we packed all belongings in the car and started for Berkeley (N.P.D.) at 3 mi. NE of Trout farm [see U.S. G. S. sheet, ed. 1918] near head of Tomales Bay² found a deer by the side of the highway – it evidently had been hit by a car; wasa or, without antlers. Noted another kingfisher near the Trout farm. Drove down Olmos Valley to Bolinas, then took road up over Bolinas Ridge by Lagunitas and Phoenix Lakes to Fairfax, thence down main hwy. to San Rafael and ferry. Reached Berkeley at about 5:30 P.M.

Hooper, 1937 Berkeley, Alameda Co., Calif. Mar. 29, The NE facing slope of Bolinas Creek Valley is thickly wooded with humid Transi- tion vegetation: redwood, Douglas fir, madros, buckeye, Ceanothus -- this from Olmos down to Woodville. On the SW facing slope the crests of the hills are covered with grass, while Calif. bay, poison oak, Baccharis are in the canyons. On Bolinas ridge (SW facing slope) near Bolinas lagoon the transition coniferal elements occur on shaded slopes. On the north side of the Ridge this humid redwood association becomes dominant. In summary of the trip from Bolinas to Fairfax via Lake Lagunitas it may be said that the humid Transition elements occur on north facing, protected slopes while Baccharis, poison oak, and Calif. bay are on the south slopes -- open grassland with occasional oak or Baccharis thicket on the most exposed warm slopes or hilltops. Loose ends of trip: Surf Scoters, noted on bay (we were en route to Berkeley or ferry); western grebes - 2 on Bolinas lagoon, 1 near Richmond ferry mole; 1? pleasant flushed from salt marshes (in Salicoria) at Birdwell;

Hooper, 1937 Berkeley, Clamed Co., Calif. Mar.29, The sharp-shinned hawk pick-up was found along the highway near the head of Tomales Bay, more specifically SW side Tomales Bay, opposite Pt. Reyes Station, Marin Co., Calif. on Mar.26. The following amphibians were collected in leaf litter and around a spring near our cabin in Inverness, 100 ft., Marin Co.: Triturus, Ensatina, Ascides, Batrachops. Other amphibians (all Ryla regilla) were taken in fresh water pools near Pt. Reyes Station, Marin Co. The jack rabbit cranium & lower jaw only was pick'd up in the Salicoma at Reisdue, 2 mi. N Pt. Reyes Station, Marin Co. April 4, While in John Garber Park on north-facing slope of Claremont Canyon, Berkeley, I noted the first Tolmie warble seen this season. It was seen about 2 P.M. foraging in an elderberry and willow thicket. Transition elements [i.e., madrone] may be fine, but the region is chiefly Upper Sonoran. Plants noted are: Calif. bog, live oak, willow, thimblebery, elderberry, alder, poison oak, Baccharis.

Hooper, 1937 Berkeley, Alameda Co., Calif. April 25, In company with Bill Engels, Bruce Whitacker and Emerson Reed I went to Pinole for the purpose of obtaining bats. The locality more exactly is about ½ mi. N Pinole, Contra Costa Co. Here are located 3 large grain barns, the center one of which is now used for storage of miscellaneous objects. In this center structure we found Antrozous pallidus [illegible] to be abundant and Tadarida not uncommon. The bats were roosting in narrow spaces located between the shingles of the roof and a 1"x12" corrising around the edge of the roof. As many as 10 pallid and 1 free-tailed were dislodged from a space 10" long x 8" wide x 1½" high. Probably 30 or 40 Antrozous could have been easily collected, however we took only about 15 - and 4 Tadarida. Here then is evidence that: (1)Antrozous are gregarious as well as Tadarida; (2)that both will roost together in the same mass. The note or voice of the two is different; that of Tadarida more shrill and faster in cadence.

Hooper, 1937 Berkeley, Alameda Co., Calif. May 25; Drove to Marin Co. yesterday with Art. Rempel of the zoology department. Our itinerary was as follows: left Berkeley at 12:45, drove to Richmond ferry, thence across the Bay to San Rafael mole; thru San Rafael north on Redwood Highway to Petaluma. Here we measured two "big game" specimens for the "Records of North American Big Game" at 4 P.M. drove back on northeast side of Petaluma marshes thru Lakeville to Napa road, thence back to the marshes immediately back of St. Vincent's School for Boys (St. Vincent railroad station) and finally back to San Rafael where we ate dinner after setting out traps on the marshes near here. Then drove back to St. Vincent to spend the night. This morning we collected our traps due and at San Rafael and drove back to Berkeley by the same route -- reached here at 7:30 A.M. There is considerable unclaimed marshland around Lakeville, but most of the land about Petaluma is under cultivation.

Koopfer 1937 Berkeley, Alameda Co., Calif. May 25. St. Vincent is about 5 mi. N of San Rafael on the Petaluma highway. ST is on the north side of the marshes at the mouth of San Gallinas Cr. (see U.S. G. S. Petaluma sheet, ed. of 19/4). Here back of the School there is an unclaimed Salicornia area of about 20 acres. Noted here: numerous meadowlarks (1 nest with 5 eggs found in thin stand of Salicornia; black- crowned night heron (3 flying over, 1 on bank of slough, + 1 on San Rafael marsh); 4 ducks (sounded like mallards); "numerous" Bo Cliff swallows (flying over Salicornia and grass land); Song sparrows (in brush borders marsh; mourning dove (a pair flushed from marsh); Kelderer (calling from mud flats); pigeants (1 flushed and others heard - just both believed to have been used by this kind of bird were seen); crows (+ 10 on marshy ground); hyla (heard croaking and 2 seen); garter snake (2 seen); spotted skunk (1 almost ran over my sleeping bag last night.

Hooper, 1937 Berkeley, Alameda Co., Calif. May 25, At the locality "St. Vincent, salt marsh, 5 mi. N San Rafael," from 50 mouse traps set in runways in Salicornia I took only 1 animal—a Reithrodontomys fulvescens. From 40 mouse traps set in Salicornia at the locality "1 mi. E San Rafael, salt marsh," I took: 2 Mns. musculus (1 a partial albino) and 10 Micrulus. Rempel caught nothing at either place (20 traps at St. Vincent, 30 at San Rafael) so I gave him 1 Mns. and 3 Micrulus (1jun., 1 7ad. & 1 9 ad.). June 1, In the course of measuring big game skulls and skins for "Records of North American Big Game" (a publication of the Boone and Crockett Club, in care of American Museum of Natural History), I have encountered and made friends with many of the so-called sportsmen of North America. Perhaps I should not say "so-called" for with one or two exceptions (all of about 30 people seen) these men do seem to have a "sporting outlook" as regards big game hunting.

No text detected

Hooper, 1937 Berkeley, Alameda Co., Calif. June 1, By "sporting outlook" I mean that each seems to expect to work for each animal secured. In order to get the "big ones" (and each does) each hunter knows he must outwit and outwork the animal. For the reason that the securing of wapiti and moose is comparatively easy, the hunter (as a rule) would rather match his wits and stamina with an old buck deer, a mountain sheep and (or) a mountain goat. For the above reason, and undoubtedly for the reason that the latter animals are not so accessible to hunters in central California, [except Grobes] many of the latter kinds were seen. On May 17, I visited Mr. Leslie Simpson of Chancelot Place, Berkeley. Mr. Simpson is one of the old-time big game hunters - one who hunted, evidently, for the sake of killing and of adding the skin or skull of the animal (if big enough) to his collection. The front room of his house, about 30' x 20' x 10 ft. (high), is almost completely covered with heads - most of them Africa - taken specimens. He spent about 30 yrs. in Africa - as a

He told me that he probably would give his collection of mounted heads to the Univ. of Wash- ington, since the officials there have promised to keep the collection intact. He does have a series of bear skulls which should go in M.V.Z. that be loaned to C.H. Merriam about 20 yrs. ago. They are skulls of western-taken animals. At Hollister, Calif.-visited on May 29+30, I encountered several people worthy of note. Chas. Lompa reported to be the one who had hunted the longest in the county, had 40 or 50 antlers nailed up on the tank house and barn; most were of black-tailed deer. Anthony (Tony) Matulich measured almost all of the heads sent in to 'Records of N.A. Big Game'. He accompanied me about to see several of the 'head owners'-helped considerably-is quite interested in hunting and head measurements. Tony has the largest mule deer? set of horns I have seen. The head resembles a picture I have seen of the set owned

Hooper, 1937 Berkeley, Alameda Co., Calif. June 1, by Dr. Beck (?) of Philadelphia - the largest in the world. I invited Tony and Carl Bleifus to visit M.D.Z. Bleifus is an interesting person. About 43 yrs. old, but with the vigor and intense interest in his work of a child, he is a "natural naturalist." With no scientific training whatever, with only a natural curiosity to see "what things are", and "what makes tem go" he has information at hand which makes one listen. He has a large collection of fresh deer heads (about 50) all well labeled and mounted. His chief interest at present is fossils. In the fossil collection he has examples of many plant and animal stuff - mostly animal. All specimens are appropriately cataloged - a number stake on the specimen which refers to a page in our leather-bound loose- leaf notebooks. Of particular interest to me was a grizzly bear skull found in San Benito County. It is a good specimen - minus lower jaws + a part of a zymastic arch. Dana sending him some M.D.Z. publications today.

Hooper, 1937 Berkeley, Alameda Co., Calif. June 1, Tony Matulich knows a man who is employed by a rich landowner (the land owned including Potrero Laveaga peaks) to trap fur-bearing mammals. If M.V.Z. is interested many skulls could be secured from him. This same landowner is said to be a 'nice fellow' and would be quite amenable to having a scientific collecting party on his land.

Hooper, 1938 [Trip to] Isabel Cr., 2200 ft., Santa Clara County, Calif., and eastern Santa Clara and Alameda counties, Jan. 6, Trip made in company with Mr. J. Paul Maslin Jr. in my auto; overnight trip. First business of day we left (Tues., Jan. 4, 8:30 A.M.) was to measure some big game heads owned by a Dr. Lockwood at Millbrae, Calif. Lockwood proved to be quite interesting and conscientious in his work as a taxidermist. Not like other people I visited he evidently attempted to present his measurements of the heads as they really are and did not "pad" them. He had many (± 75) heads, some of which should be among the "first" in the list. Most of his specimens were taken in western North America by various hunters (not himself) though there were some from elsewhere, notably Africa. Noteworthy perhaps are three sets of bighorn horns taken from western Nevada. He also knows of another person who has a complete head from this same region. There were several moose, mt. goat, wapiti, many sheep and deer, and several pronghorns and caribou. It may be worth while to keep him in mind for sources of specimens.

Hooper, 1938 Isabel Cr., 2200 ft., Santa Clara County, Calif. and vicinity. Jan. 6, Left Lockwood's place at 12:30, rolled in Burligame, then drove to San Jose, whence took road to east to Mt. Hamilton. Followed road by observatory on down northeast side of Mt. Hamilton to Isabel Cr. (c. to the U.S.G.S. sheet, 1906, where the road crosses the creek at about 2200 ft.) We camped and trapped on the floor of the flood plain near this point. The next day, after picking up the traps, we followed the road on down Arroyo Bayo (poor road, along creek bed) into San Antonio Creek drainage and San Antonio Valley thence north along Arroyo Mucho to Livermore. Trip from Isabel Cr. camp to Livermore took about 3 hrs. The country about Mt. Hamilton is typically Upper Sonoran. I saw no organisms which could be considered Transition indicators. The slopes of Mt. Hamilton and, as well of other "hills," are much as those seen on Mt. Diablo. Exposed faces, tops of ridges, and south facing slopes are grass covered with occasional oaks and digger pine. Shaded canyons have a growth

Hooper, 1938 Jan. 6, of Canothus Arctostaphyhus, arbutus, Aderostema, occasional Roschhus and thymbellaria. Some shaded canyons were found to be quite moist at this time of year; seepage from soggy ground supplied the necessary moisture for rather luxuriant growths of ferns and other mesophytic plants. On the north side of Mt. Hamilton (away from Santa Clara Valley) vegeta- tion is more abundant. More Coulter pines were noted and, as well, a short-needled pine with a dark green foliage and a profile much like that of Pinus radiata; these latter pines were few. On this same side of the mountains was found a more abundant growth of Adenoxema+ and Canothus ; however, most exposed slopes were still grass covered. Along Arroyo Bajo and San Antonio Creek were occasional junipers - found chiefly on north and sloped slopes. The country in here is more today; places (ie., habitats) where I would expect to find many Peromyscus trees, P. californicus, Reognathus californicus,

Also Q. douglasii.

Hooper, 1938 Jan. 6. and Dipodomys hermannii and probably D. venustus, were noted here. The flora and fauna was found to be much the same (with local limitations, of course) all the way north to Livermore Valley. Very little toison oak and some toyon was seen. Oaks were chiefly Q. Kelloggii (blue), Q. agrifolia; (lower) on lower slopes were Q. lobata; on slopes (as seen at Isabel Creek camp) was Q. dumosa? (scrub). Birds noted: Plain titmouse, California gay, Red-shafted flicker, Red-tailed hawk, Western Crow, California Thrasher, Calif. Brown Towhee, Wren-tit, Audubon Warbler, Junco, White-crowned sparrow, Horned Owl, Turkey Vulture, Killdeer. In Isabel Cr. Triturus were found to be abundant (We had picked up two from the roadway en route to camp). In the evening when we arrived they all seemed to be moving up-stream. Two kinds were noted: one rough, rugged, dark; another larger, more soft + slimy, and lighter yellow in color. [see note Jan.t)

Hooper, 1938 Jan. 6 we spotted (with lights) many swim- ming slowly about in pools; some were laying eggs - hind feet were clasped together near the genital orifice on ventral side of body, seeming to serve to catch the eggs and hold them together and to some bit of grass or debris until the mucous substance around the egg swelled + held them together. Pool saw pairs in amplexus Tues. Afternoon; I saw others wed. morning; however none was seen in this condition at night. I set out 100 mouse traps about 10 faces apart in Adenostoma, Ceanothus, and Q. dumosa, and beneath fallen trees; traps baited with oatmeal. Also 2 rat traps - one under log; one in rock lodge. Wood rat sign abundant. Saw deer tracks "almost everywhere" and coyote (?) tracks along the creek Found in traps Wed. A.M.: 5 Peromyscus californicus and 33 P. truei . I discarded 23 Junes mice. One rat trap and about 10 mouse traps were spring but empty.

Hooper, 1938 Berkeley, Alameda Co., Calif. Jan. 31, Notes on "Day Shoot" held by members of the Calaveras County Sportsman Assoc. (Calaveras County in Calif.) This is the second shoot held Jan. 30, by the association at which M.V.Z. members attended. Miss. Mary Erickson and I were on hand in April, 1936. See our notes on that trip. Left Berkeley with J. H. Tait and F. Richardson in Dodge truck. Drove out through Hayward, Livermore & Tracy on U.S. Hwy. 50, then turned (east of Tracy) north on Hwy. 99 to Stockton, thence north- east on @ through Linden, Bellota, Jenny Lind to Valley Springs; lunch here 12:30-1:15. Then to San Andreas where tried to contact sportsmen, store owners, etc but with little luck; thence to Angels Camp. Returned home via same route. Left Angels at 8:20 PM; reached M.V.Z. at 12:50 PM. Total mileage 250 [miles]. No shoot was held in 1937. This is apparently due to lack of a unifying head to call the shoot and, too, probably lack of interest. The affair this year was under the leader ship of Mr. F.J. Gillo, an affable and pleasant owner of a Gents Furnish- ings store in Angels. He seemed to be Treasurer of

Hooper, 1938 Berkeley, Alameda Co., Calif. Jan 31, the Association. He cordially took us 'in tow' and presented #us (#) to the other men and (#) with some desirable information. 'Methods of shoot: No sides chosen this year; the competitive spirit was diminished but not lacking. About 20 men shot birds; 30 (#) at dinner afterwards. Instead of a barbecue, as in 1936, the group met at 'Jones Place' a restaurant and saloon in Angles. Each man purchased his own meal at 50¢ per. Afterwards, there apparently was to be an official meeting of the Association. We were on hand at 6 PM with Mr. Grillo. The first hunters to come in arrived at about 6:15, the last about 7:30. Jays were brought in (contained on string- like line of fish - in paper bags and burlap on the floor- sacks) and dumped with or without ceremony" but always with such remarks as 'How many, Frank, Joe,' etc. Apparently their hunger drive was much stronger than their curiosity to get the total count for the day, because at 7:30 they all retired to the 'dining room' and we were left to count the birds and, finally, with more hardselling, flattering words, etc., to take our leave.

Hooper, 1938 Jan. 31 Area covered by hunt: about as in 1936 - approximately 20 x 20 mi. (400 sq mi.) - but not at all well covered by men. Area extends from Murphy & Angeles down to San Andreas. As mentioned before about 20 men hunted - 4 from Angeles and all or almost all the rest from San Andreas. Bag: Number shot per man ranged from about 3 to about 30 (No accurate count made). Total birds: 166- Steller, 63- California, and 1 Cooper hawk. A scalp of 1 house cat also appeared. Time spent per man: 1 hr.+ to "all day". The fewer men shooting was explained on several counts: (1) Dance Sat. nite in San Andreas - with "aftermath" today; (2) Cloudy cold weather; (3) Lack of interest; (4) lack of competition; (5) "had to work". Fewer jays collected due, almost mani- mously, to "cold, cloudy weather - makes birds stay in trees & brush"; when disturbed from hiding place, would fly to tree, then out a other side immediately, and would not drop from bottom to top of tree - before flying - as on clear days." Incidentally, we too found this to be true, in general.

Hooper, 1938 Jan, 31 Other gems gathered from their conversation: Mt. Jays most abundant here now; they move up-mountain in spring. Results of the two shoots we attended will bear this out as true. Few, but some, actual sights of jay eating (1) young (brains pecked out) (2) eggs - sucked (evidence here doubtful), of quail. Little or no difference in quail population seen in foot year or so. 3 - "[illegible] Hawks" or sharp-shinned (called so by 1 person) killed at game farm - each with a quail. "Mt. Jays not as noisy as Valley Jays," Many coyote about, found squirrels few, only seen in local places. Gray squirrel becoming more standard; begieved to really be on upgrade. Several reported that they "look closely at each one to see if it looks healthy. If it looks scabby or sick, I shoot [illegible]." They seem to well come, truly, their increase. campaign for squirrels. No poison or Predator Control (other than their own) carried out for several years = 3 yrs., at least. These cats are definitely in ill repute.

Needless to say, each was quickly destroyed. “Dumping” of cats in wild reported as still going on. At their holdery or game farm they are raising Chinese Pheasant, Chukar Partridge, and quail. All will be liberated this year. Some quail were not free but they continue to return to the game farm for feeding! The “keeper of the game” reports Tonora, Calif. association having good luck with Chukar Partridge. liberated last year or year-before-last “many” young birds have been seen. Most of the men seem to realize the “squirrel” difference in appearance between “soaring,” “chicken”(accipiters), and “bullet” (sparrow) hawks and (2) their chief foods. They seem- butterfly taste on the center group: “A hawk is a beast to be killed” has lost some of its venom, it probably still applies somewhat. All have a good time.

Hooper, 1935 Berkeley, Alameda Co., Calif. Mar. 7, Saturday PM at about 2:30 left Berkeley in M.V.Z. truck #112 with Dale Arroy and Chandler Nottle for overnight trip to set marshes on S.F. Bay side in Marin Co. Arrived at our first destination - marshes at the S.P. Railroad Station Manzanita at about 4:30 PM. Set traps here then progressed northward to large marshes continuous to but east of Corte Madera and Sausalito. The marshes lie about the mouth of Corte Madera Creek. After setting traps at 2 places here, went 3 mi. north to San Rafael for dinner & picture show. Then back to marshes to stop. Picked up traps Sunday morning & returned by same route (Golden Gate Bridge & Oakland-S.F. Ferry - and via Bay Bridge goning over -) to Berkeley, where arrived at about 10 AM. It had been raining when we arrived at the G.G. Bridge; even we began setting traps it began again and kept up a slow drizzle interposed with hard showers until we left Marin &. This rain undoubtedly affected our trapping results - if it did not affect the activity of small rodents (and I believe it did) it did set off many of our traps.

Hooper, 1938 Berkeley, Alameda Co., Calif. Mar. 7, Mangarita is a station on the electric railway (Son. Pac.) which runs from San Jose to San Rafael and lies on the west side of Richardson Bay. Widow Reed Cr. empties into the marshes on which it lies. Here salt marsh, Mangarita, Richardson Bay, Marin Co., Calif. I set out 14 mouse traps in low Salicornia and rushes; traps set about 8 ft. apart and about 25 ft. from automobile trestle over the marshes. At the next morning I found: 1 Microtus, 2 Reethrodontomys and 2 Peromyscus. The second locality trapped (salt marsh, 2 mi. ESE Costa Madera) was on the marshes bordering S.F. Bay proper and at the south end of the region about the mouth of Costa Madera Cr. The locality is adjacent to the high, non-marsh land at the north end of Tiburon Peninsula. Here where I trapped the grassy hillsides bound the salt marshes - separated only by the roadway. I put out 31 traps in sparse Salicornia and in rushes and some wild oat (little, along the road) Found Sun. AM: 1 Peromyscus, 1 Microtus, and 6 Reithrodontomys. Microtus runs

Hooper, 1938 Berkeley, Alameda Co., Calif. Mar. 7, were abundant. One was seen running through the vegetation. About 1 mi. NW of this locality in dense, high Salicornia (~2 1/2 ft. high) along the railroad tracks to Liberon Penins., I put out 44 mouse traps about 8 ft. apart. Found Sunday: 3 Microtus, 2 Reithrodonys, and 2 Mus. The latter 2 were discarded. This locality = salt marsh, 1 mi. ESE Corte Madera. As a result of this trapping it is apparent: (1) That Reithrodontomys raviventris occurs north of S.F. Bay. (2) That its presence here must be explained. (3) That its range may extend on northward to that of R. thalictes. (4) That R. raviventris and R. megalotis occur together where the grassy slopes meet Salicornia. (5) That trapping must be done from San Rafael northward to clear up some of these matters. The fact that R. raviventris doesn't occur out of the Salicornia would seem to me to indicate that it is a native kind to this habitat which has spread here from the south or that it has been intro- duced into an unoccupied niche or displaced heterote.

Hooper, 1938 2 mi. W Oakley, 50 ft., Contra Costa County California. June 21, Left Berkeley this morning at 10: A.M. with Dawson Feathers in my Plymouth. Drove on main hwy. to south side of Corquinez Bridge. Stopped there to look for ground squirrels. After about 45 min there drove thru Crockett to about 1 mi. E SE when and where again hunted for squirrels. Drove into Martinez, after hunting at above locality for about another hour, for lunch and food for tonight. I hence to Concord and Clayton, over Marsh Creek Road to Cherry Canyon on the south fork of Marsh Creek. Up Cherry Canyon to about 1000 ft., then back down and to main highway on north fork of Marsh Creek or Road to Byron. 5 mi. W of Byron we turned north to Brentwood, thence north and west to this locality: 2 mi. W Oakley, 50 ft., Contra Costa County, California. Here in mixed area, (1) part uncultivated and with rather thick stands of Adenostema, occasional tree oak and undergrowth with wild oats and brome? and (2) along edge of grain field I set 69 mouse traps about 10 pace apart.

Heppen, 1938 2 mi. W Oakley, 50 ft., Contra Costa County, Cal. June 21, The hills between Crockett and Martinez are gently rolling, resembling those around Sofayette and Walnut Creek both in vegetation and in topography. Exposed hill tops and sides (but for canyon bottoms) are grass-covered. In the canyons are live oak, occasional Calif. bay, buckeye, poison oaks, and a few rose thickets. Few areas were seen which would provide cover dense enough for wood rats. The range of hills to the northwest of Mt Diablo and Mard Creeks are entirely grass covered. No canyons with chaparral or trees were noted on the creeks' side of those hills. Curry Canyon, from the mouth apparently just about to its source, is pretty much the same. In more moist and sheltered areas are sycamore, maple (few), bay, buckeye (much), rose. Poison oak abundant; hazel not seen. The understory is covered with dry grass and leaf litter - poor picking for mammals. P. maniculatus would be there, but not abundant. Probably P. truei would be few. Adenostoma stands prevail on the upper slopes of Mt Diablo Peak - as east or S-facing and crests of slopes from about 2500 ft. on up.

Hooper, 1938 Jmi W Oakley, 50 ft. Contra Costa County, Calif. June 21, In Curry Canyon noted: Black Phoebe, Black-headed Grosbeak, Plain Titmouse, Green- casted Goldfinch, Sharp-skinned Hawk, Turkey Vulture, Western Bluebird, Bush-tit, Calif. Quail, linnets, Barwick Wren, Steller Jay, Calif. jay. Sandy areas on the Marsh Creek Road on Canada de los Poblanos and in Brion's Valley support ground squirrels - probably nothing else, as regards native mammal life. Oakley is quite sandy. The sand extends hillward at least 2 1/2 miles, then stops abruptly to adobe soil about 3 1/2 mi. SW of Oakley along foothills. All this area is under cultivation except, apparently, this small (4 acres) plot. Perhaps the vegetation here will give one [illegible] an idea of the nature of the area before being cleared. Open oak woodland giving way to thickets of densostruma with occasional Artemisia. Dry wild oats matting ground under all. Soil almost driftable - is driftable when not vegetation covered. Pocket gopher diggings abundant. Cought nothing in traps last nite.

Hooper, 1938 Sarco Co, +1000 ft., 6 mi. NE Napa, Napa Co., Calif. June 22, This AM left previous camp to drive here for short stop (now 2 P.M.). Drove over Antioch bridge, across Shemman Island to Rio Vista thence to Fairfield and to Napa and up Sarco Creek road to this camp. Shemman Island is completely(or almost so) under cultivation. I saw no Salicornia patches--which is to say that salt marsh mammoths are now practically nil. Probably the marshes near Fairfield are also under cultivation. Could see no marshes near Fairfield. Potrero Hills and Montezuma hills are all dry and grass-covered. Some sandy areas--and formed as a result of dredging activities--were seen but they evidently supported only jackrabbits--as regards mammoths. Sign here was certainly scarce. All of the area is probably flooded during extreme high-water years. The hills on each side of Napa Valley are pretty well covered with vegetation beginning with open grassland down low and near the mouth of the valley oak woodland (+grass) gives way to manzanita and chamise, and finally

Hooper, 1938 Sarco Cr., #1000 ft., E mi. NE Napa, Napa Co, Calif. June 22, Douglas fir-madrone association - as one goes up-valley to more & more protected, cooler places. This canyon, in which we now are, may mark the southwesternmost limit (north of S.F. Bay) of redwood association. Here about me in this canyon bottom are: redwood, alder, black willow, huckleberry, madrone, poison oak, apple, buckeye (1 or 2), hazelnut, douglas fir, live oak, bay, long-leaved (?) willow, "vine-bush", bracken. The zonation in the canyon bottom I would also say is good transition. Upon the slopes in the chaparral = Upper Sonoran. 9 mi. NW Colistoga, Sonoma Co, Calif. June 23, Drove back to Napa, thence north thru St. Helena & Colistoga, north west on road to Geyserville and Healdsburg... About 46 traps on N-facing slope in alder, live oak, madrone, Douglas fir, redwood, deciduous oak; poison oak near stream (hillside above), for most part! Took 2 L. truei and 16 P. maniculatus. Took 5 L. maniculatus and 3 Microtus on dry, S-facing slope in grass (dry).

"deciduous oak" = F mercus chrysolepis

Hooper, 1938 9 mi. NW N W Calistoga, Sonoma Co., Calif. June 23, This area probably was a seepage spot now dry. On Mt. Helena, as on Mt. Tassajara, Mt. Disblo + Mt. Hamilton, the top of the mountain is evidently lower zonally, than are the lower needles. On top and down S side dense thickets of Adenostoma and Arctostaphyus exist. In sheltered canyons and on north side are: redwoods, Douglas fir, madrone, alder, bay, deciduous oak =?, Some Coulter pine down lower and, as well, also present on floor of upper Napa Valley. June 24: 2 mi. E Stewarts Point, Sonoma Co., Calif. Drove north past main highway (road to Guadala) and turned east on Shaggy- Stewarts Point road. Are now camped in typical redwood association. Good redwood stands were noted where we passed over the summit to direct coastal drainage. The chaparral belts - of mangarita and Adenostoma, briefly - were restricted to drier more exposed slopes. Last site I set out traps in 4 situations, as follows + with these results thus a M: 27 traps at 1/4 mi. E of Stewarts Point on hillside in rip

"Rush" = sedge ( Carex obnupta ) [illegible]

Hope, 1938 2 mi. E Stewart's Point, Sonoma Co., Calif. June 24, glass and under Sanctuaries, monkey flower and broken clumps - also few manzanita; netted 1 Microtus & 4 Peromyscus m. Feathers took 1 Microtus- 20 traps set. (2) 1 mi. E Stewart's Point from 14 traps set in marshy area with large broken & rush clints- by fallen, rolling logs took: 1 Peromyscus maniculatus (on logs), 1 Sorex pacificus (on mat floor) + 1 Sorex sp. (on mat floor); Feathers took 1 Sotpaludicus, 1 Neustrelis, & Peromyscus on log from 15 traps set in marsh. (3) 14 traps set in rushes or hillside among redwoods & Douglast: 1 P. maniculatus & 4 Microtus. (4) 25 traps set along roadway in redwood forest. 2 Peromyscus maniculatus + 1 Sorex (in mossy ground under broken on hill); Feathers took 1 Peromyscus m. from 20 traps set in scrubby situations. The area about camp and extending down to within 1/2 mi of the sea is typical redwood association. Redwoods, tan oak, madrono, Douglas fir make up the mass of the superstrucy, broken, monkey flower, alder, thimble- berry compose much of the understory.

"bracken" = Pteris aquatina sword fern = Polystichum munitum "Sedges" = rushes (Juncus sp) = large clumps. "rye grass": Johnson grass (Holcus lanatus) Also there in marsh: Rumex acetocella L. (Sorrel or dock)

Hofen, 1938 2 mi. E Stewarts Point, Sonoma Co., Calif. June 24, Immediately adjoining the sheep[illegible] grossland coastal strip is a strip of Pimus muricata - also a few P. contorta. June 25, 3 mi. W Inverness, 300 ft., Marin Co. Calif. Are now camped at the top of the ridge draining to the southwestward into the ocean and northeastward into Tomales Bay. Mr. Acker the caretaker and warden for the PT Reyes hunting club has most cordially extended us a welcome and has provided us with a bunk house in which to seek shelter from a dammably cold wind and fog. I set out 70 mouse traps in the marshy meadow on the coastal slope draining to the ocean. Vegetation here is rank, composed of sedge, sword-fern clumps, rye grass in the most moist moist area giving away to canothus cumps on west-facing slopes and Boccheris on the road side. Along the creek are willows and occasional alder and lays. Catch: 1 Newstricrus, 1 fox, 1 Reithrodontomys, 2 Peromyscus m., 2 Microtus.

Hooper, 1938 3 mi. W Inverness, 200 ft., Marin Co., Calif. June 25, Noted the following on drive south from Stewarts Point (which, incidentally, was via Coast Hwy #1): the grassy coastal slip widens as one progresses southward until at about Valley Ford (just south of Bodega) it spreads clear across to Sonoma Valley. Deeper canyons to the north of Russian River harbor serve thickets of Baccharis etc., F. muricata. To the south of here no pines were noted and in the

Hooper, 1938 Olena Cr., 175 ft., 2 mi. SE Olena, Marin Co., Calif. June 27, Day before yesterday (June 25) left Inverness camp, drove back to main #1 hwy. near P.A. Reyes Station, thence southeast thru Olena to above-mentioned camp on Olena Cr. We are now camped in willow thickets 50 ft. from the stream; Five Brooks is about 1/2 mi. up the creek from where we are. As shown on the P.A. Reyes U.S.G.S. sheet (2d. 1918) alongside Olena Cr. Inverness Ridge is heavily clothed with timber: dense stands of large Douglas fir, madrone, California cay, tan oak; also maple, canyon oak, poison oak, thimbleberry and 1 large redwood. Redwoods become more predominant on Pine gulch Creek (draining into Bolinas Bay). Mr. Boyd Stewart, a Stanford graduate and a most cordial and helpful host, tells us that the above slope about 100 yrs. ago was much more open - this before the redwoods the Douglas firs were at all set - The open meadow-like slopes are now filled in by young Douglas fir, madrone, bay. Redwoods did not come back.

Apofer, 1938 Olewa Cr., 175 ft., 2 mi. S E Olewa, Marin Co., Calif. June 27, Last night I set 60 traps on the grass-covered SW-facing slope. This am found 3 Peromyscus m. and many spring traps. I had sceptically sought for kangaroo rats. As noted above, the northeast slopes bounding Olewa Cr. are grass-covered and - as usual for this type of country all over the Bay region - grazed by cattle. In the canyons are growths, as on the slopes across the creek (Douglas fir, etc.), the density of the growths varying with the depth, steepness (in other words degree of protection of the canyon; the differ from those on the NE-facing slopes in having more poison oak and live oak. On the NE-facing slopes of Bolinas Ridge the same dense stands are found as on Drwerer Ridge. The forests are advancing up over both ridges, young tree and other invaders (blackberry & Baccharis) noted on the tops of both ridges. Bolinas Ridge, Mr. Stewart tells me has never been cut.

Hooper, 1938 Olewa Cr., 175 ft., 2 mi. SE Olewa, Marin Co., Calif. June 27; Mr. Stewart leases grazing rights from the Marin Country Club people. They own most of the country on Drakes Ridge extending from Olewa south most of the distance toward Woodville - exactly how far I don't know; their land extends from the west side of Olewa Creek to the Ocean. This area, during most of the year is a reserve for most wild animals. Of course game birds are taken in season and probably some predators are removed, however because of of the comparatively few members of the club (about 5, according to Stewart) and because the area is not traversed by any public road other wild life can hold forth unusually unmolested - for the area about the Bay. Mr. Stewart allowed me to accompany him yesterday over to the Drakes Bay side of this property he leases. The road followed turned off the main highway at Five Brooks. Passing thru two locked gates we drove about 4 mi. + by road (1 1/2 mi. - map distance) SE

Hooper, 1938 Olema Cr., 175 ft., 2 mi. SE Olema, Marin Co., Calif. June 27, of Five Brooks. Up to the summit of the ridge the vegetation cover is as described before - large Douglas fir predominating. At the summit there is an abrupt break to mixed grassland - on some more wind- blown slopes and or meadowlands- and chaparral. The latter foredom- inated by far above the former at least to within 1 1/2 or 2 miles from the coast. Perhaps it continued on too the coast. The thickets were composed of Baccharis, poison oak, blackberry, wild rose, thimble berry, salmonberry, poison hemlock, sword fern; an occasional live oaks or Bishop pine dotted the area. Several lakes with no outlet, and several marshy areas were noted. I set 4 mouse traps in the chaparral which netted this morning; 1 chipmunk, 2 microtus and 1 Peromyscus maniculatus. 30 traps set in a marsh, with a sedge as the dominant plant, netted 8 Microtus 2 Peromyscus m. and 1 song sparrow. 4 Aplodontia sets yielded nothing but 1 spring trap.

Hooper, 1938 Berkeley, Alameda Co., Calif. June 28, Left camp on Stewart's place yester- day about 2 and drove along coast highway #1 thru Stinson Beach, to Manzanita where we rented a tent house in an auto court for the night. I set out 50 traps in Salinas in the marshes opposite Lakesport where I set before. Because of the extremely light tide I caught no manimals - only 1 song sparrow, the traps were floating in many sets. I twenty-seven traps set in re- gress near the edge of the marsh at the mouth of Elk Valley yielded nothing. I drove up Elk Valley to within 1/2 mi. of its mouth on the ocean side. The entire valley is grazed by dairy cattle; nowhere did I see any likely Zapus country. At the sea coast mouth (Tennessoe Cove) there appear- ed (from 1/2 mi. away) to be a marshy area grown to sedges. However this, too, contained grazing cattle. This morning, after gathering our mammoth catches (!!) we drove over Richmond-San Rafael Ferry. Distance for trip = 490 mi.

Notes. 1938 2 mi. S. Saratoga, 2000 ft., Santa Clara Co., Cal. July 9, Left Berkeley July 7 at 2 P.M., picked up Dawson & others in San Leandro, drove across San Mateo Bridge to Skyline Blvd., thence north to Sharp Park road to coast; thru Sharp Park and Moss Beach to first camp at N side Halfmoon Bay, 1/2 mi. N Pillar Pt., San Mateo Co., Calif. After 1 mile's trapping, there drove on thru Halfmoon Bay (town) San Gregorio, Pescadero to Gajoz Cr. road (about 5 mi. S Pescadero), thence over this road to Big Basin, up to Skyline Blvd. and Saratoga (Santa Clara Co.); camp now on property of R.R. Stewart. Now to go back a bit: stopped at several places along coast highway (#1) to look for Aplodontia burrows: near Montara, Purisima, Gajoz Cr. Found country likely (vegetation favorable) but no burrows. Open grasslands not so abundant as north of bay from Marinto Sonoma Co. along coast. Chaparral areas more numerous, canyons deeper; much of the tillable ground (on all of it) grown to artichokes and peas - little pastureage. For vegetation types see U.S.F.S. and U.C. Experimental Station "I after map" for San Mateo

Oenothera hookeri also noted along cos in more moist areas.

Hooper, 1938 2 mi. S Saratoga, 2000 ft., Santa Cruz Co., Calif. July 9, quadangle. The coniferal belt extends coastward to within 4-8 mi. of the coast on the route we traveled. It comes closer to the coastline as one progresses southward toward Santa Cruz. In Gajos Cr., for example, we came to Douglas fir (as we went up the creek) about 2 mi. from the coast. These, of course, were in the canyon bottom. About 5 mi up the creek there were good stands of Doug fir and redwoods on protected slopes as well as in the canyon bottom. Chaparral wood was cent (except in burned over areas) 7 mi from the coast. On the Sharp Park - Skyline Blvd. road there were no conifers - just grassland and chaparral. Camp on mile of July 7 on N side of Hoffman Boy was made at the edge of a perman- ent, fresh water marsh 1/2 mi. N Pillar Pt. The marsh is about 6 acres in extent; vegetation here: Typha, Carex, Juncus, Salix, Rumex, Coriuna, Mimulus (- Diplacus - ). Some of it resembles the marshes W of Inverness on P.X. Route Rd. where Zapus have been taken. I set traps as follows: 13 on hillside in yellow

"yellow button plant" = Colutea coronopifolia

Hooper, 1938 2 mi. S Saratoga, 2000ft., Santa Clara Co. July 7; bush lupine netted 3 Peromyscus maniculatus and 2 Mus; 16 set on same hill (exposed slope) caught 2 Peromyscus m., 1 Reithrus rodontomyx, and 1 Microtus. 21 along small stream (1 ft. wide, 1 in. deep) in dog fennel, daisy and yellow button plant caught nothing; 75 in marshy area mentioned above caught 2 Sorex, 15 Microtus, 4 Reithrodontomys. Feathers set 85 traps in the marsh to get: 2 Mus, 2 Reithros, 14 Microtus, and 6 Peromyscus. He also caught 1 Norway rat and 3 brush rabbits in 5 steel sets. In many places in the Santa Cruz Mountains we saw large areas (entire mountainsides extending for miles) grown to chaparral (Adenostima, Baccharis, Ceanothus, etc.) which we thought should be covered with coniferous forests. In many instances this chaparral evidently was the "invasive" after the area had been burned over, or logged first then burned over; dead spars could be seen. The succession of animal life accompany- ing this should be kept in mind.

"Rhamnus californica. Ceanothus thyrsiflorus. Sphacele polygama. Arctostaphylos glandulosa. "grass" = Bromus and Avena chiefly.

Hooper, 1938 2 mi. S Saratoga, 2000 ft., Santa Clara Co., Calif. July 7, Our camp here 2 mi. S Saratoga is on the high ridge lying to the South of that town and bounding Santa Clara Valley on the west at this point. This property owned by Mr. Steward Stuart is that which I either watched over as caretaker several years ago. Zone here is Upper Sonoran grading into Transition in protected canyons where stands of Douglas fir are found. Around complete - typical for much of such NE-facing slopes on the SW side of Santa Clara Valley - are madrone, boy, poison oak, live oak, thimbleberry (little). Around on the Southwest-facing slopes, most exposed, is Adenostoma and Baccharis. On the crests of ridges and hard, rocky soil is grass and Yerba Santa. These a circle of here within 100 yds. radius are habitats for: (1) heteromyids (kangaroo rats + pocket mice & jackrabbits; (2) wood rat, P. truei, P. californicus, wood rat + chipmunk. Old apple and cherry orchards, now allowed to "go back to primitive" offer additional food for kangaroo rats & the three Peromyscus

Hooper 1938 2 mi. S Saratoga, 2000 ft., Santa Clara Co., Calif. July 9, + 6 rat traps set I set 75 mouse traps in an apple orchard and along the rocky thorn bay- oak - poison oak, Baccharis, and adenostoma. Took: 7 Peromyscus californicus, 3 P. truei, 6 P. maniculatus and 6 Dipodomys (4 D. venustus? and 2 D. heermanni?). Feathers set 8 traps in similar situations but more in orchards undergrown with grass (oats, foxtail) and took: 10 P. maniculatus, 1 Peromyscus californicus, and 6 Dipodomys (of 2 birds?). July 10, Set out 50 mouse traps laid out on top of a ridge 1/2 mi. S of camp in an old grape orchard. Wild oats were thick and about 2 ft. high between the grape vines. Burrows of kangaroo rats, apparently, with no dirt before them and Peromyscus m. - smaller and with dirt before them - were numerous particularly near the grape clumps. Also set 5 rat traps about house here at camp. Adenostoma, poison oak and yerba santa bordered the above orchard. Found this am: 13 Peromyscus m.,

Mt. Melogamy = Cercocarpus betuloidea manzanita = Arctostaphylus glandulosa also brome grass (Bromus) here -> found in pockets of Dipodomys and Perognathus fruiting structures at mouth of burrows of Peromyscus m.

Hooper, 1938 2 mi. SW Saratoga, 2000 ft., Santa Clara Co., Calif. July 10, 1 Peromyscus californicus, 2 P. truei and 2 Cleognathus c. Sollers got 1 pocket mouse and a flock of "P.m.s." in his traps. Noted about camp additional vegetation: Quercus, Juncea, and toyon, mountain mahogany, pitcher plant (Drosera?).

M.M. Mahogany = Cercocarpus betuloides "Ceanothus" = C. cuneatus

Hooper, 1938 Berkeley, Alameda Co., Calif. July 13, about 5 mi. We drove on east (on road to Livermore) looking for good pocket mouse country (Artemesia and rocks), but found nothing better than that on most exposed slopes north of Diablo Cr. I was mistaken in thinking I had seen Artemesia in a rocky canyon about 5 mi. east of the above camp in with the junipers which are found there. I set 31 traps in a S.W.-facing slope among grass and near or under mountain serbogyry, a dwarf Artemesia? (± 10 in. high) and! A few ground squirrels were seen here and some burrows apparently of Dipodomya. From those traps: 2 Dipodomys h., 1 Peromyscus m., 1 Peromyscus californicus, 1 P. truei. In similar situations but with more traps in dried "gramininae" ± 1½ ft. high from 60 traps Feathers took 1 Perognathus c. and about(!!) 10 P. maniculatus . 14 traps set along the edge of brush (= Adenostema, Canthusa curvata, poison oak, and fallen coulter pine debris) netted 1 Dipodomyx (from holes in sandy ground near brush), 2 Peromyscus californicus. 2 P. truei.

Hooper, 1938 Berkeley, Alameda Co., Calif. June 13, I also set 50 traps among poison oak, California bay, Santhus, and yellow pine; substrat mostly rocky (rocks ranging from 6 in. diameter to large boulders) -- like a talus slope in the Sierra Nevada, but rocks rounded, water-worn. Many of the rocks covered with moss, now mostly dry, and area giving evidence of considerable down-work of water in wet season. Took from traps: 7 L. trui + 2 L. californicus. We estimated that there were 135 yellow pines (mostly large trees of about 3 ft. diam.) in the area of about 20 acres. They are not in pure thick stands as a rule but mixed with P. coulteri and, less often, with P. sabina. Vegetation bordering or among them: Calif. bay, Santhus, manzanita, madrone, adenostima, Coulter pine, digger pine. Some of the area seems excellent for chipmunk subsistence and possibly gray squirrel, but none was seen. After picking up traps drove back to Berkeley, arriving here at about 11:30 A.M.

Hooper Citellus douglasii Noted workings on exposed "overgrazed" hillsides along the "Redwood Highway" from just north (+1 mi.) of San Rafael to Petaluma. Seen within 200 lyds. of tide lands near Petaluma. Account of trip of June 21-June 28, 1938, north of San Francisco Bay in Counties touching on the bay: Passing over Antioch Bridge thru Rio Vista to Fairfield: I noted no squirrels until about Benverton. One picked upon the road about 3 mi. SE Fairfield was put up by D. Feathers. The country south of Cordelia out toward Benicia probably supports these animals. Montezuma Hills also probably harbors them. No signs of the animals were noted on embankments on the N side of Antioch Bridge. All the ground around and on Sherman Island up to Rio Vista is under cultivation-asparagus mostly-and probably does not harbor squirrels. Hills not having too high glass and above high water level are potential ground squirrel areas. None noted in redwoods or in coastal grassland belt-ie, grassy hills bordering the ocean and to 1/2 mi. to 3 mi. back.

They were seen intermittently all this area traveled yesterday - any where there were exposed, warm slopes, grass- not too high; both in dry, hard soil and sandy soil (near Canada de los Poblamos and Briones Valley - on Marsh Cr. Rd.) and where there was not a heavy growth of any vegetation (trees, shrubs or grass). - dougleen - On north side found a ground squirrel dead on road; hit by car - this about 3 mi. E Fairfield. Noted none on the island (Sherman). Probably they don't range quite to the marshes on the north side of the bay. West field margins (or rolling hills) evidently could support them. July 7-12, 1938 A resident of region near Lunitas Cr., San Mateo Co., said there were a few of this species in the hills back (+ 1 1/2 mi.) from the ocean. Saw none in Santa Cruz mountains. Seen to summit of Mt. Diablo Hamilton; wherever not brushy but grassland.

Hooper Entomias merriami 2 mi. SW Saratoga, 2000 ft., Santa Clara Co., Caly. July 8-11, 1938 These animals are abundant about our camp here. We have taken 12 by trapping or shooting. Definitely a brush-inhabiting kind; they are found in a chaparral type tree growth here composed of: Calif. bay, live oak, scrub oak, poison oak, manzanita, baccharis, mountain mahogany, blackberry, yerba santa, canthorus and some mint (?). Old apple trees that have been surrounded by this brush served as a focal food point for them. They were also seen feeding on this mint (?) and in blackberry brambles. They were not seen in pure stands of Abroptoma, though in some stands the plants were 8-10 ft. high and thickly placed.

Hopper Eutanasia sonorae vicinity of Stewart Point, Sonoma Co., Calif. June 24, 1938 Feathers & I neither saw nor definitely heard any of this species. However at the General Store in Stewart Point we were informed that "chipmunks are very abundant at the Indian reservation up at the summit" (= about 10 mi. E Stewart Point on Slaggy Spring road). Since the same person said that "they are only a few up here in the redwoods" (= region about our camp - 2 mi. E Stewart Point) and since we saw two, perhaps there is something to his statement. The immediate area about the reservation settlement is partially grown to chaparral; to the west of the clearing are large stands of redwoods - i.e., that association; to the east it semi-bushy forestland, i.e., brush or some slopes, forest or others.

Hooper Reithrodontomys halicoetes 1 mi. W Avon (salt marsh), Contra Costa Co., Calif. Feb. 28, 1937 Traps baited with oatmeal and placed in Microtus runways yielded at least 4 R. halicoetes. They were found in the same immediate area with R. megalotis. On at least one instance one trap contained a megalotis and the next trap, about ten paces away, held a halicoetes. As I look at the skins of harvest mice all collected in the same marsh and on the same trap line, it seems to me that 4 are R. megalotis and 4 R. halicoetes. On the same line were caught Mus musculus, Sorex sp? and Microtus californicus. St. Vincent, salt marsh, 3 mi. N San Rafael, Marin Co. May 25, in 58 traps Caught 1, set in runways in Salicornia.

Hooper, 1937 Notes on Captive Reithrodontomys Berkley, Alameda C., Calif. Mar. 10, 1937 Bar between 12 o? and 2 m? & down tonight. The two are now in the same cage. No auto[gonism] Mar. 11, Still no auto[gonism]. Both in same cotto[r]. April 6, 2 m? and 12 o? now separated into adjoining cages. No signs of auto[gonism] noted during period when the two were together. One thing noted tonight when I was clearing the cages may be of significance. Reithro-dontomys megalotis are much more active than R. raviventris - this has been evident ever since both birds were confined; the former climbs and jumps about wildly; the latter seldom climbs up on the wire, and has never been observed to jump to the side or top of the cage as the megalotis does. Well, anyway, tonight the megalotis, as usual, could not well be cornered - it jumped about on the bottom and sides of the cage attempting to escape. The raviventris on the other hand seldom ran on the sides of the cage (up off the substrata, thus) and attempted to burrow in the sawdust of the cage floor. This was a means of

This might indicate that raviventris seeks retreat in the ground (it lives in Salicornia - which offers little climbable structure), while the megalotis kind may attempt to escape up off the ground or by running and jumping in its chaparral and grass habitat. April 7, Found the raviventris or back in the cage with the megalotis ?. The former went back thru the hole in the partition to its own cage when I started to catch it. The hole is patched now.

Hooper Aplodontia rufa 3 mi. W Drurness, Marin Co., Calif. June 25, 1938 Feathers and I located the colony reported by Taylor, Camp, Ferris et al when they were here earlier (1912?). It is on the ocean drainage side of the hill over which the Pt. Reyes highway passes exactly 1 mi. by my speedometer by road from the Caretski's house at the crest of the hill. The ridge on which they are found faces SE and is densely clothed with chaparral, contrasting markedly with the open grassland and semi-open Bishop pine forest higher up on the ridge and less marked with the Ceanothus-studded opposite slope. Vegetation immediately about the dens: blackberry, baccharis, wild rose, thimbleberry, salmon berry, poison oak, sword fern, brockeh [illegible], monkey flower. I see top of the hill and the opposite slopes are more exposed. The burrows are 6 or 8 in. in diameter with loose dirt before them and open into the hillside generally under a dense sword fern clump. One burrow may open not over 1 ft above a lower one. Feathers took 1 young animal in #1 jump trap. We took this to camp &

Hooper Aplodontia rufa June 25, 1938 kept it for 3 days. It took sword fern fronds and water readily, was rather docile, making no definite passes at the observer. "Appy" finally died; due to, evidently, to peritonitis extending up the leg (where caught) into the body cavity. 1 1/2 mil. by map) SW Five Brooks, Dummer, Ridge, Mass. June 27, 1938 Using criteria as follows we located the colonies here: (1.) Drainage to ocean directly; (2.) within fog belt. (3.) protected, nother moist slopes heavily covered with plants listed above (4.) sword fern. We made 4 steel sets, and (since we had no other larger traps) 2 with gopher traps & 4 without traps. This morning, however, we found no animals (other than Peromyscus m) in our traps. Two traps were springy, the burrow opening closed in the mud with the Peromyscuses. I noted country which seemed to meet the above criteria just south (along hwy. # 1) of Stinson Beach. Probably they could be found there, too.

Hooper, 1938 Aplodontia; July 13, Looked for workings south of S. F Bay from Sharp Park south to Gazoz Cr. (±6mi. S Pescadero). In many canyons we found cover which seemed ideal for these animals, as on Moxter Ridge and near Juritas Cr. On Moxter ridge on N facing canyon walls + on canyon bottoms the vegetation is thick and composed of: Baccharis, poison oak, poison hemlock, ceanothus, thimbleberry, blackberry, sword fern, bradley, monkey flower, and Carex. These dense thickets were in canyons draining directly into the ocean and within the fog belt; they seemed to not to provide almost identical conditions as on St. A[cres] where they do occur. Plants identified at suburban: Everlasting flowers Graphalium + Aurephalis Ceanothus chrisiflorus.

Zapus ovarius 3 mi. W Inverness, 300 ft., Marin Co. June 25, 1938 D. Fethers took one in the marsh 1 mi. down the road from the summit of the hill - this on ocean drainage. Vegetation here is as follows, chiefly: clumps characterize it - clumps of sword fern and of some sedge; in the intermediate areas are rye grass and some other low lying grass; along the creek which drains the area are willow, alder and an occasional bay tree. Elk Valley, Marin Co., Calif. June 27, 1938 Searched this valley from one end to the other for likely areas for Zapus. This in response to skulls of these animals found in owl pellets from here by Cranston Hopkins & Clarence Smith (See Condor, 1938). The valley is heavily grazed by dairy cattle. Only at the two mouths (ocean bays) might these be found. 27 traps set in high rye grass near (50 ft.) Salicornia at the bay mouth near Margate netted nothing. The marsh at the ocean end was not examined.
