J.P. Pearson 1947 Journal Swager Canyon, 8200 ft., Linewater Mtns., Mono Co., Calf. July 20 Left Berkeley in Power Wagon, 6 AM, arrived Swager Canyon about 4:30 P.M. Benson shot a Eutamias at Leanitt Meadows on the way down the east face of the Sierras. Put out 35 Museum specials along stream in grass (6 yd. intervals), and 32 Benson line traps-- all baited with walnuts. Put out ca. 5 P.M. Checked the line traps at 9 PM and they contained 1 live Zorex palustris, 1 live Peromyscus, and 1 dead Zorex sp. July 21 Coyotes howled ca. 4 AM. Snap traps held about 5 long-tailed Microtus and 4 Peromyscus, and one Zorex sp. One more P. leucinus in line traps. Z. palustris was dead in cage. Skinned til 10:30 AM, then put out more traps after muleba palabra re. sawing of data from discarded specimens. Put 95 traps (Benson, line) at 12:30 PM on hill behind camp as follows: 19 in bunch grass. 19 in artensia 44 in mabogang 5 in tulna {baited with seed. 19 more in mabogang. 16 more in artensia also put 49 museum specials along the stream at the western edge of the valley; 3:30 PM., walnut bait. While setting this line I scared up a Zapus who, in trying to escape, jumped into stream and swam across ferhly, presumably by same jumping motions as on land. Caught him by hand.

P. PEARSON 1947 2 and caged him. July 22 The 49 trap traps along the stream had the following score: 6 Zophera, 6 Microtina longicaudus, 1 Microtina montana, 4 Peromyscus, 1 Perogratthus, 2 Sorex sp., and 6 Sorex Palustris - total 26. The original line of 35 traps along the other stream: 3 Microtina montana, 2 Mm. longicaudus, 3 Peromyscus, 1 Zophera. The original line trap line had 1 Sorex palustris in same hole as 1001, and 1 Microtina longicaudus. The chipmunk lines of live traps as follows: 19 in grass - 3 Peromyscus and 1 Lagurus (baby) 19 in artimesia - 2 " and 1 " adult (caged) 44 Mahogany - 2 Peromyscus. 16 more in artimisia behind camp - 4 Peromyscus, 2 Lagurus (babies) and 1 Perogratthus. No chipmunks in this line in A.M., but 4 more in it at 2 P.M.; 4 young ones, probably E. x shot 3 others in mahogany region at 2:30 P.M. The 49-trap line caught 2 Microtina longi and 1 Sorex palustris during the day. One of this morning's Zophera was caught by the base of the tail - apparently dead. Later removed (see Zophera notes) Shot a Mygtha after dusk, too dark to read newsprint.

Pearson 1947 3 Spent much of the day shuning water skrews, Nearly blew a fuse thinking of the time going into Lorenz n+1 to enlarge an already lengthy series while 90% of my catch was rotting in the sun, never to be looked at even. Benson's theory seems to be that Microtus etc. reproduce all right without my worrying about their reproduction, and that we will never get anywhere studying the microfauna of the Sweetwaters if I spend all my time looking for scent glands etc. At least that was the gist of yesterday's discussion. Today I am a yes-man and advance Science by putting up on Lorenz palustris coward- but not coward or converted. July 23 Temp. 36° before swamp, and some ice on grass overhanging stream. The original 35-trap line caught 2 Microtus montana, 5 Pruisens, and 1 Zapun. Picked up the original line trap line in which were only 2 Pruisens. The 49-trap line along the sweet stream had 8 Pruisens, 3 Microtus longicaudus, 3 M montana, 2 Zapuns, and 2 Sorex palustris in the morning, and 2 more Sorex palustris in the late afternoon. The chipmunks line traps in the morning were as follows: 19 in grass - 3 Pruisens and 1 Logurus, 19 in artumezia - 2 Entumas and 1 Pruisens. 44 in scrubbing - 4 Pruisens. Also shot some

P. PEARSON 4 chipmunks making a total of 8 in the morning, 5 of them in artemisia and 3 in mahogany... appearently all same kind. There were 3 more in these traps in the P.M.: 2 in artemisia and 1 in mahogany. Picked up those traps in P.M. Saw a cottontail in the mountain mahogany this morning. Drove to Bridgeport at lunch time - half hour drive each way, I continue to catch (and shoot) nothing but young appearing chipmunks. July 24 The original 35-trap line caught 4 Pameins, 2 Mierstra longicardus and 1 [illegible] sp. The 49-traps line caught 1 Mierstra, 1 Pameins, 1 [illegible] sp, 3 L. palmatris, and 2 Jepsons, one of which was caught by the trail and curled up in hibernating position. I'd later recovered. Hoped to get off by lunchtime but many chipmunks and a porcupine shot this morning while cony-hunting slowed things down. Found mole trochs in the aspen grove below the meadow, so we stayed overnight after Benson set for the moles. But shooting as usual in evening. July 25 One mole and a gopher in the moles traps. Couldn't trail down the mountain Mahogany in Jepson. Saved specimen of it and [illegible] Left about 9 AM? for Bridgeport, Brockie, anvra, and Fletcher, looked for bats in

P. PEARSON 1947 6 July 27 My 50 live traps in the sand caught only 3 Pimiceus + The 100 snap traps in the dunes caught 2 Microdipodops, 1 Eutamias, 15 Pimiceus, 4 Dipos ordii and 4 Dipos leuco, July 28 Fletcher. Put up late in the morning, then left for Haulthorn. Stopped just over the divide to look for crows on the S.E. slope of Cory Mtn. Found drop-slings, hay piles, and heard crows calling but didn't see any. Then went through Haulthorn and drove up Corey Canyon to some mice on the S.E. face of Big Indian Mtn near its top. Saw crows there and missed some with the shotgun in the late afternoon. Saw small dragging in the dry rocky-sandy road shoulder a little above the reservoir in Corey Canyon. Slept in upper Cat Creek at about 9200 ft. July 29 Fletcher. Hunted crows early in the morning. We shot 11 between us and saw a few more, then drove down Corey canyon to the Reservoir to skin them. Looked for moles in open gorges on the way down and for more crows in a good big web slide at about 8400 ft., but saw neither crows nor moles. Did see moles in sand + (tunnels) sagebrush near Fletcher lava flows. Supper of steak and watermelon with whisky jock at Fletcher (Davis) and stayed with him overnight. Four more bats in the old house were collected before bed.

1945 J. P. PEARSON June 21 - From Berkeley to Monterey to Mariposa, cherries ripe and very first peaches. slept in gross - blue oak rolling hills west of Mariposa. numerous california ground squirrels and [fly catfish crossed out] kingbirds; coyotes) landed during night June 22 Yosemite Valley in morning, camped at Teraoya Lake in afternoon. Many deer along the road the road below Teraoya and at teraoya. also saw 3 marmots (1 at Teraoya), california and Beldings Ground Squirrels, chipmunks, 1 coony at close range at Teraoya. June 23. Drove to Soda Springs and parked north toward Young Lake. The last half mile of the trail was blocked by snow - drifts, so camped on a ridge (10,000 ft.) west of Rogged Peak among Lodgepole Pines. Mountain Hemlocks and White Pine and Red Fir nearby, also two Douglas Squirrels on this ridge. TH. June 24 Decided to park back to Dog Lake to camp. Many deer. Many fishermen and mosquitoes around Dog Lake (and Ground Squirrels) so camped on the hillside north of the east end of the lake. Pine Lodgepole Pines that had been burned over many years earlier, a few mosquitoes at camp but they disappeared before dark.

J. P. PEARSON June 25 - Awakened by snorting & stamping of deer. A buck stood 20 yards from our sleeping bag eyeing us menacingly while a doe stood quietly about 20 yards beyond him. His horns in velvet, just beginning to branch. As we watched him, a martin hopped downhill between us and him, stopped momentarily to look at the deer, then disappeared downhill. Chipmunks & probably Douglas squirrels at comforts. After breakfast climbed via Marine T hut to the ridge (11,000 ft.) southward above Taylor Lakes. Many deer (perhaps 16 in the 3 hr. walk up). The lodgepole pine gives way at about 10,500 to whitebark pine which became quite stunted and finally disappears just short of the top of the ridge. At very top saw Belting Pond begraciously, chipmunks, and Sopher earth caves. The white-bark zone was covered with ?? deer? (or sheep?) droppings. Heard one come at close range at about 10,500 ft. Very large droppings at about 10,000 contained deer hair and hoof covering, probably farma. Have found no cowboy hay piles - possibly because there has been practically no green fodder available. Am surprised at the absence of green grass, alpine flowers etc. Numbers have we seen such growth. The

Tivolino, Trigra Pass (very dryings), Mono Lake, then 22 miles out the Mary Road thinking it was the Bodie Road. Flat tire on way back, so skipped Bodie and went to Snoger Canyon near Bridgeport. Picked out 25 new aluminum Shermons along stream in middle meadow, and 25 Bensons. Many Boltting ground squirrels along road west of Bridgeport. Two deer in Snoger Canyon at supper time and one porcupine in willow? shrub along stream in middle of the meadow. Man in Bridgeport say snowfall in Sierra look scanty.

Swam so rapidly that 1/200th second probably didn't "stop" him - certainly a neat trick to snap him in an appropriate pose as he zipped past the lens. Shot 5 Bedding Ground squirrels to get liver + brain to feed the waterskews. They definitely eat liver, earthworm, and caddis larval, also another large scorpion-like aquatic insect larva. cent put out 24 aluminum Shermans and 10 Bensons, Tom put out 14 Bensons and 3 Shermans and I have 24 aluminum Shermans and 25 Bensons.

At 11 p.m. last night saw another porcupine in a st. miller bunch out in the meadow - this porky looked almost as big as a bear. On the 7 a.m.-run caught a bob-tailed Soreh sp. out in the grassy meadow. She died in the afternoon. Much mammary tissue and 9 small embryos - probably her second litter. Saw a cottontail? in the arterias and Hallwell spotted wood-rat nest on top of a rocky pinacle. The first zopuas that had been hibernating died, a male, no fat. The three to-ist ones so far have been & 8. Reranged trap lines in seach of more Zopuas. All so far baited with walnuts. Have seen two Zopuas at night, both in the water in narrow streams, trying to leap but waterbound. June 29 Ram line at midnight: 6 zopuas, 1 water shrew and 1 Microtus. Moon came up at 2 p.m., at 7 a.m. 4 zopuas, 1 water shrew, 1 Peromyscus, 1 Microtus.

Pearson 1945 June 30 Several of the colatus zopna have died. There seems to be poor survival for those found torpid in the trapa. Trapping score overnight: 3 Merotus, 5 water shrews, 6 Zopna, 4 Peromyscus. I'm preparation for leaving tod to release some water shrews. One bird escaped from his cardboard box and 4 others we released and lost trying to photograph. Set up the camera at a very nice mossy bit of stream by a waterfall etc, with a rock in midstream. Hoped to get get a shrew to pause on the rock for a picture, but they dashed off with astonishing rapidity. Only one of the four (2 of them twice) = 6 attempts waited for the shutter to click - and he was one who had gotten his fur wet + disarranged. They swam from the rocks to the banks (about a foot) and disappeared into tunnels which I'd not seen before, occasionally reappearing at other holes when glimpses are caught of them running across an opening or along the edge of the stream. they look very Blarina - like - especially if the long tail is hidden. When two met in their tunnels, they uttered a series of grating squeaks or chirps not unlike those of Blarina. Some of our released ones met several times in the tunnels both under the banks. We dug out one of these tunnels. There were two openings opening above water under

P. PEARSON 1948 the overhanging banks. These joined after going in and up for about a foot, then this tunnel went up about 6" more and downstream about 6" whereupon it opened into a chamber the size of a large coffee cup. This chamber was almost filled with a nest of green plusquam thin pieces of bark. A tunnel led beyond the nest & downstream downward. no young or fresh scale in the nest, so it is not impossible that it belonged to Zapena or Micotina. Captures eat earthworms, grasshoppers, raw liver, mouse carcasses (except forest skins), dead fish, caddis pupae, aquatic larvae of insects (many live in this stream), large flies (catch them on the wing), some bugs, but in one trial they refused flatworms which abound in this stream.

rides, He does use them when turning or when pushing off the bottom. The tail oscillates rapidly laterally but probably resulting from the movement of the hind feet rather than from any primary propulsive movements. He moves at least as rapidly underwater as above. When turned surface swimming along the edge of the Hildebrand fish pond he could 2 ft. per second (= 1.3 m.p.h.), all observers agreed, however, that when startled he went much faster - probably twice as fast. A silvery film of air is trapped when he dives, and he usually by his fur emerges quite dry. One was dumped from a jar into the aquarium for photographing and came up soaked. He climbed ashore and proceeded to scratch and dress his fur. In two minutes he was about half dry and despite numerous short swims he dried even more in the next few minutes. The same (and other) observers when raced into the water don't get nearly as wet. This suggest muscular control of the hair to prevent wetting. Try cutting series on one side. Warm water slightly wet now than cold also. Longest dive so far is about 2 seconds - fairly long aiven for such a little tyke. They can jump at least their own body length out of water.

1948 Person Aug 23 Left 9:30 am. with Jennifer, Worman, auntie Pearson, and Katherine Fligg for Calaveras Dam (Alameda Co.). Arrived down 11:30. Hot and sunny, water level of reservoir low. Mr. Macarthy let us into the large (20ft. diam. +/-) concrete inspection tunnel and the smaller pipe tunnel on--the both--which run into dam. Much grass near entrance of larger but no bats seen in either. also much grass in the tunnel where the pipe enters hill below --4 mile below dam, but no bats infest 100 yds of this tunnel. Many droppings around edge of tile roofed aerating bldg., but saw only one bat under the tiles, probably Myotis, but couldn't poke it out. Macarthy makes weekly inspections in the first two tunnels and doesn't see bats there ordinarily. He does see them flying around the mouth of the tunnel "about 7 or 8 o'clock." Saw a doe and large fawn in the swampy place below the dam, and occasional ground squirrels along road between Milpitas and the dam. also "" at the dam. Stopped at 3 wooden bridges and a few abandoned houses on way home, but no bats. Home 5 p.m.

1945 Pearson Aug 28 0 (bot) Journal 16 Santa Cruz Island, Pisonero Harbor, Santa Barbara Co. Left Santa Barbara about 1 p.m. D.S.T. on the Blue Fin Beverly Alexander, Captain. Sea very calm. Saw 1 school porpoises, also seals? and sea lions. Sharks astonishingly abundant: Pitelka estimated 5 per acre and 113 per acre over a stretch of several miles (somewhat crossed out on the mainland side of mid-channel). Some weighed well over 30 lbs, and I saw 2 that had been hooked that were 4 to 5 feet long. The ones out in the channel were "backing" with dorsal fin and tail exposed. When swimming the tail is not moved strictly laterally, but in a slight arc -> [drawing] stern view Landed at Pisonero Harbor about 3 p.m. No one in sight crossed out around the pier or in the buildings thereabout & walked up the valley about 3 miles to the ranch buildings where we found only a Chinese cook and one ranch hand. The manager and 3 other men showed up later and we cleared with them about staying at Pisonero Harbor in the house there. First impression of Santa Cruz is none of a rather steep sloped island, misty-foggy around summits, eroding rapidly; vegetation principally live oak, ceetia (crossed out) cota and cerecylptus + Because of drought almost all

P. PEARSON 1948 the cattle have been moved off of Stanton's end (west) of the island. They have only a half- dozen cattle around the ranch buildings. There are some wild pigs and wild sheep. One smallish pair (maybe 40 lbs) lay dead along the road, appearing to have been shot. Numerous jays seen, as well as amer. eagle, ravens, dove, killdeer, house finch, Benick's war, shrike, black throate, Rufous-crowned Sparrow-p, Jays and frogs calling after dark. U.S.C. Marine Laboratory yacht lay off the pier when we returned (about 6:30) from the ranch buildings, and apparently is going to stay all night. Aug 29 The half-dozen traps around the house caught 4 Peromyscus alitulus, 1 jnr, 1 pug, 1 [illegible], and 1 adult vole. Saw no bats flying but 2 in the abandoned "New Orleans" house. Shot one of them, a Corythomene, at 10 p.m. Weather overcast till noon, then sunny. Put out about 90 Museum Specials baited with walnuts, mostly in rocky-open areas and along an oak gully. also 6 steel traps for foxes. Saw flicker, sparrow hawks, Pheasants?, hummingbird sp., wandering tutter, gt blue heron. about 5 p.m put about 30 museum specials along the flat, dusty bed at the mouth of the river", mostly along the edges which are walled up in places, rocky in others and cut through shell strata in other. Very clearly defined mouse runways wind in places and dense the dusty open places toward the pebble beach -- such too clearly

1948 P. PEARSON 18 marked, also smell for ? tucbs in the place, and pig. It seems rather strange to clamber over the hills here for several hours and see no signs of rabbits or ground squirrels or meadow mice, or gophers, and practically no sign of any mice. One certainly can't blame the pigs for the scarcity of small mammals, for there is still lots of food and cover (and Heteromys lives independently amidst many peccaris). If Peromyscus is the only mouse, it should be interesting to investigate its abundance, is it more abundant here, without competitors, than elsewhere with? Aug 30 Twelve Peromyscus in the traps (about 120), aside from the 6 pit ups there were 3 adult males, 2 min. females, and 1 min. male, also one Philodelus in jump trap at edge of stony beach at bottom of gully. Stomachs contained arthropod remains looking like "beaks" of batylids, limbs + abdomen of Jerusalem cricket, and possibly small crab limbs. Also found some droppings, not yet analyzed. Biggest disappointment in the trap line was not the occurrence of only Peromyscus but the abundance of ants. 90% of the traps were battlesome in AM, mostly an account of very tiny ants. Captured 9 peppers (Hyles) in the circular stock tanks last night, and one in the marshy overflow from it. Noticed that bats were drinking from it so tonight strung 2 no. 26 wires across it // a foot apart and about 1 1/2 inches above the water (tanks 6" diameter). Out of

P. PEARSON 1948 19 perhaps a hundred "drinks," only 5 touched the mines: 2 of these flew up and 3 splashed the water, but none [illegible] were trapped in the water for even a half- second. Left out same traps plus 5 more steel traps for foxes, these at the mouth of the "rivers" where there are numerous small fox tracks. Weather clear and sunny all day. A navy PT boat discharged 5 people in civvies in morning and they drove inland in the navy jeep for several hours. Returned in mid-afternoon and left on the PT to return next week. Offered us the use of the jeep anytime. Aug 31. Despite not rebaiting many of the traps, caught 11 Peros, aside from those not put up [illegible] out 3 males and 2 females. Steel traps did better with 2 foxes and [illegible] 2 skunks. The latter, although only about 4 pounds, seem to be adults, judging from the reproductive tracts. Their trocals are so dainty they would be dwarfed by those of eastern red fox only a month or so old. Both these were females, but the captain of the Santa Cruz says the males are only a little bit larger. He also mentions large colonies of Rats up in the ranch buildings. Rats "of this kind" a large feral one and another. Picked up a considerable part of the mouse trap because of skinning activities didn't rebait all of the remainder - or all of the steel traps. For bat hunt see copy somewhere

20 P. PEARSON 1948 Sept 1 Yesterday and this morning there has been a decided prev-dawn or crock of dawn but flight around the house. One more rufus in the traps no bigger than the others. Spent day shining her and fox, as well as finishing yesterday's skulls + skeletons. Took jeep up to radio station about 6 miles east. Located on top of steep southern slope. Country between here and there mostly grassland, between grassland but some coctus (dunton), oak, mangos etc. Very dry. No signs of mammals but must drop some of the grey hills to see if Peromyscus can cope with them. The hilltops are hot, even when it is cool (but sunny) down here. Patler found the same thing this morning. Four businessmen - goaters stopped his for water this morning. They have been stopping at various north-shore caves and mention not valleys with pools of water deep enough for swimming, and with ferns as high as your head (they may have seen all this in earlier years). They admit that things look dry now. They are particularly enthusiastic about Painted Cave - a long sea tunnel running back into the island 250 yards, containing seals and maybe bats. They weren't quite sure of the latter. From the radio station - the south of the steep hills at the eastern end of the island is quite reddish and looks more barren than here. To the west

the island looks large and very mountainous, hardly seeing to have flat space enough for a landing strip. Dept 2 went jeeping to the west end of the island (Christy's Ranch) and airport. Again noticed how it is really hot and seemingly even drier up in the hills. Saw one rather extensive stand of pine on a north slope just as you drop down toward the airport. Many seedlings, floor rather dry and open, general terrain not greatly different than rest of island that we have seen: oate, oak, opuntia, manguito, rockwhis, mtn. mahogany. Interesting group of buildings at Christy Beach: barn, hen coops, stone dwellings, etc. A couple of 2 corporations in one body, and a snake on the ridge top of other over hen coops Nice sandy beach below Christy Ranch with foot tracks. Took following pictures: Super xx #8 - pine slope, looking east. Slope on left (south facing) with no pines, mostly grass & opuntia (overgrown) #9 - pine slope + opposite slope looking east (from further away, #10 - north side of central valley going down to Christy, opuntia and Bacchus in foreground #11 - Pitillo in jeep #12 - north side of central valley between main ranch and the divide to Christy, looking west.

P. PEARSON 1948 22 Ranch hand named Sonny and another dropped in after supper. according to Sonny (age 25, been here since 1937) there were as many as 20,000 sheep on Stanton's property. Most of them were shot during the war. He, his brother, Stanton, and a friend, shot 600 in one afternoon. They must do it on a big scale because we saw nearly 8000 rounds of .218 Bee ammunition at the Christy Ranch just setting out on the table in the abandoned house (= #640). They shipped off the cattle last winter on account of drought - just before the rains finally came. Sonny says that in the vicinity there is another kind of boar than Corythornis - bigger and darker [Entozymus?]. Also, a skunk-sized animal that smells as bad as or worse than a skunk but pale brown. He says no rats, lots of "field mice" around the buildings. Also ferl cats. They hunt mice at night with dogs & killed one soon tonight, a boar and 2 young got away. Days Indians lived on the island, and we have found several human skeletons in the shell heap at the north of the "river". Left 3 Are more skunks in the Trefolios. Spent the morning stiring yesterday's lots, skunk in the p.m., and getting ready to go up to the pine forest for the night to set out a line of traps there. The trees cover one whole side of a ridge (north face) just over the divide from the main road to the airport. mostly 5" to 1' in diameter, but lots of seedlings. Floor mostly open - but a few shrubs scattered through (mostly cusicoons). Manzanita in bloom and in fruit around th

upper margin of the pines, good needle litter on the floor, very moist in some places, but no tunnels in it and no invertebrates seen while rolling logs, scratching for tunrels etc during trap-setting. Numerous spiders seen while jack-lighting, but nothing else. Jays very numerous and fearless in the pines. Elevation must be about 1200ft. After sunset it was quite windy (warm breeze from North) upon the baretop of the ridge, but no wind in the pines. Considerable dew fell late in the night and at dawn the Christy Ranch rally was well-filled with fog-banks - a fog that must have covered most of the pines, although not the uppermost. Sept. 4 70 museum species in the pines caught 3 Peromyscus: one immature, one adult with smashed skull, and one adult with back end eaten away. Not as much ant trouble as elsewhere stopped at ranch or my home and got 9 Antrozana out of the attic of the minery. There were several hundred others there as well. Also some fresh vegetables from the ranch garden. In the evening talked with "Red" Crane, the ship captain and manager. He says Stanton brought in 20,000 geese every year, but had trouble with ravens attacking the lambs. Killed the ravens with thallium, also killed off most of the logs with introduced log cholera. The ammunition we saw at Christy Ranch was just "odds & ends left over" from 100,000 rounds

P. PEARSON 1948 24 bought for killing sheep at a range of 50 to 400 yds. They undoubtedly shot tens of thousands sheep. Sept 5 at 6:15 a.m. date, shortly after dawn, saw a mygotta crawling going to roost on the wall of the house only 10 feet from my sleeping dog, and another a few minutes later, both went into the cracks between the trim around the windows and the clockboards. Later I removed 7 from such places around the house. No fliers or flyers, only 1 Pero, although not many traps set. Pete, who has worked on the island for 47 yrs, says the island will support 2000 steers. This figure is probably for Stanton's end of it. The gardener Wilkinson shot 5 sheep about 1 1/2 miles where this morning. We had the hindquarters of one for dinner... slightly coarser than domestic dry leg of lamb, slightly gamier (not as lamby).

He even saw two hogs, Went up near the radio station (unoccupied) to set traps in crossed out: around the late afternoon, put out 100 mouse traps around opuntia islands in the grass, across a weedy arroyo (not met), [illegible] in open grass, and up a grassy gulch. Cool and foggy at darks. Also 2 foot traps in trail on edge of oak park. Safest 7 Raw and foggy in a.m. Peromyscus in each of the places mentioned above, most of all in swamps (14 traps) and around opuntia. 15 Peru all told (114 traps). No jays. all grown Perus in breeding condition, both ? and ?, Many returned today and will be back tomorrow for a short stay. Probably mean no jeep for us after tomorrow. Picked up the foot traps on the ridge and in the canyon west of campo. Put 100 traps around the barn, feed house etc. at the Stanton Ranch Hydro, as well as along the stream below the ranch. The latter in an attempt for shrews, but saw no holes or tunnels in the grassy- herbaceous--rocky stream border. Also 3 foot traps in the vineyard and looked for bats in various of the ranch buildings. So far haven't found any predators on Peromyscus. Foot + shrews stomachs + droppings are hairless and have seen no owls. Ranch hands say they have seen "monkey-faced" owls, but these can't be our

abundant. Aside from the Peromyscus put up, there are 5 males and 4 females. Sept 8 a dozen traps in barn, feed room, etc., caught 2 Pero. about 75 along the stream below the ranch caught 13 Pero, although something had taken the bait from all but a half dozen (possibly beetles that squeak when touched.) Since they were baited just before dusk they must have had bait for the early part of the evening. Saw a single Corycorhamus in the bottom floor of the winery (where antrozens lives above). The eclipse vineyard is overrun by quail. The grapes are fed on by turkeys, corns, skunks, pheasants, and probably pigs + fofez. Caught a shunk in the vineyard. Aside from the Peromyscus put up, through out 8 ? and 3 ff s. Small bats flying over the bench at the edge of the hayloft - aerials. Sept 9 Only traps out were those in the swamp, the foot traps, as a handful of museum species in special situations. cought only 2 Peromyscus. Also 1 more Myotis in north of the house. Spent morning skinning Pero and more antrozens from yesterdays catch. Put out a new trapline in afternoon of about 60 museum specks and 6 steel traps.

Saw a sheep in one of these canyons - a few green acorns are beginning to fall. Sept 10- 12 Persevering in the traps in the east canyon. No jaguar or shrews. Left that line out and put 6 steel traps in the canyon and along the beach between here and Pebear Bay. There is considerable mangroves and cancratothylus and some phytania on the slopes near the north shore. Near the mouth of the second really big canyon west of Prisoner's Harbor is a considerable area of tumbled large boulders with a few living pines and many dead ones. Very old trees of five. The first really big canyon narrows into a very steep-walled chasm with in places the floor scoured down to bed rock, numerous dry falls, and in 3 places deep rock basins full of water at the bottom of these falls. The water very dirty (from hoep + sheep?) darkfull of mosquito larvae and tadpoles. Shot 1 Mosquito flying over beach, some kind of in swalls of house. The "May" people stopped in today.

P. PEARSON 1948 28 1:30 p.m., to return Monday. Sept. 11 Mouse traps up the valley caught 4 O[illegible] and 3 & 4 Pero; one I put up. The new super for line (6 traps) caught nothing. In fact, 2 of the traps had been seen for droppings within a yard of them. Caught another skunk up the valley. Picked up these 6 steel traps and put them in the forest looking canyon on the near side west of here. Apparently [Peromyscus] & red raccoon aren't too effective as bait. May try apple tomorrow. Several photos: Briscoe's Harbor from the west looking east; Coyunta Island, grass, and oak on the hill west of P.H. (Pero caught here); looking south or SW showing mostly the east facing slope of our valley about a mile above P.H.; Briscoe's Harbor from west-facing slope above the valley south of P.H.; meadow utility trees & skunks; trunk and trunks and joy. Saw some sort of a fire on a steep north slope about 5 miles east of P.H. It seemed not to have spread 2 hr later. Radio people say there is a hot sulfur spring south near the northeast coast. Sept. 12 - One more fox (in a fisher-baited trap), but again a female. Rebated all steel traps with apple, also put out more mouse specks in the scirpus-typha. Went riding in the jeep this morning to the pine forest on the [illegible] Ranch - Chisty divide; thence down a very dry and barren valley to Laguna. Picture of low red-sand ridge along the south ridge road, looking west. Also 2 photos of mangenta-sawtooth-adenotata-coanathus.

Tolls with Ned Crane and perusal of ranch records reveal that the winter of 1940-41 was a very wet one with 56 inches, whereas last winter was very dry with only about 10 inches, 4 of it early in the fall and then practically no more until March. Low temps. reach about 27°, altitude of the dry lake and open area from which several Peromyscus came last Monday in 1200 ft. About 3 p.m. drove up to the radar station for gas. Although cool and misty here, it was extremely hot and sunny up there with a stiff, dusty, dry wind. The "fire" seen yesterday was what the ranch hands refer to as their "volcano" - a fissure out of which steam (or smoke) escapes: Heard a baracund this p.m. - perhaps the most important Peromyscus predator, Stanton's end of the railroad covers about 54,000 acres. Bat-hunting at dusk up the valley among the oaks where the stream crosses the road - lots of moths, but caught only a few quick glimpses of bats. Sept. 13 - Nothing in the steel traps. Saw two musk rats of deer, and a sow with 4 spotted young. The mouse line in the Serpents caught 4 Oryzomys and 17 Peromyscus and prairie, are Bothrodontops.

Sept 14 The 120 rednut-barkta muscica set in and around the scirfens - Tylops march caught 1 more Reithro but no Pero. Would have effected at least a half dozen Pero, and would not have been surprised at a dozen. Moon almost full. The Reithro was in a gr grassy tongue projecting into the scirfens. Skinned it while out on the pier waiting for our boat. Because of fog, however, boat didn't arrive until 4 p.m..

PEARSON 1948 Myotis calif. Sept. 1 - a lone small bat flew about the yard several times this evening, long after dusk. Others have been seen fluttering but none collected yet. Sept 2 - one Myotis? flew around inside the house for about half a minute at 6:30 a.m. d.st., then disappeared. It was quite light outside. Sept 4 - Noticed two going to roost at 6:15 a.m. d.st in our house at Presque Harbor. After several zooms they landed and slipped into the cracks between the clapboards and the trim around doors and windows. Went around the house later and removed 7 from such locations, all on the south or west side of the house. 6 males and 1 female. Sept 6 2 more so? in same situations Sept 7 1 more ??

P. PEARSON 1948 Corynorkia Aug 29. Have gotten two so far, both at about 10 p.m. in Sept. 1 abandoned house; both at places where they had not been earlier in the evening. They come to water at the stock tank later than [illegible] some other species, probably Myatis. Corynorhina flight is more butterfly-like than others. Last night found about 20+ flying about in the abandoned "New Orleans" house where one had been shot at 10 p.m. two nights before. This was about 8 p.m., a time when none were yet flying outdoors. Herded 10 of them into an escape-proof room and stunned them all (with Pat's help) by swinging a pair of pants and a trip bag at them. All females except some young males. Have not yet [illegible] found any in this building in the daytime, although they probably live there somewhere. Tonight at 8 p.m. a dozen or so were flying in the same place. Wanted to get about 2 adults for tomorrow's skirting. The first two stunned were young ones, so released them outside the room. At least 1 of the next 3 is young, but have kept them alive to skin tomorrow. Sept 2 Got up into the attic of the "New Orleans" house by way of the dormer window, 10 a.m., some squeaking inside, and about 200+ Corynorhina in 3 or more clusters in different parts of the attic. Picked down a dozen or so but could find no other species. Released 5 at our house and 2 of them flew directly (100 ft.) into the dormer

Peromyscus P. PEARSON 1948 Aug 28 Two on the doorstep of the house at Bix, Harbor between 9:30 + 10 p.m. (D.S.T.), another slightly after 10, and still another later in the night. Aug 29 Of the above 4, one was a ♂ with large testes (11mm., tubules not visible), one a preg female, not yet with adult pelage, one a lactating female, and one a juvenile not saved. Aug 30 Caught 12 in about 120 traps, but many lures stolen by ants. All traps were rebated in a.m., but not all in p.m. Aside from those just set up, there are 4 adult males, 2 imm ♀♀, and 1 imm ♂. Caught a few by hand near the house while jacklighting. Aug 31 Have collected 2 so far with of tremendous size for a Peromyscus maniculatus, both with rather scarred tail and thin fur - perhaps old age and perhaps not. Sept 7 All adults have large testes or are pregnant Sept 7 A skunk today had a Peromyscus almost toto in its stomach Sept 11 Caught one weighing only 15 gms, yet in adult pelage, another weighing 18 gms (skin saved) was still in gray/pelage, yet had large uterine horns, large vasculosa ovaries etc. Sept 12 Heard bawn owl

Foh PEARSON 1948 Aug 28 - Saw no tracks in the dusty road from Pearson's Harbor to Ranch (about 3 miles), although there were small boy or sheep tracks in several places. Ranch manager says collected here "about 10 yrs ago" and caught "lots of foxes" but that there are very few now because of disease. He has seen one recently. Another man (the milker) has been on the ranch only a few months and has seen none. Aug 29 - Made 6 fox sets along pig-sheep trails, in gullies, and along pebble beach. All baited up high with carcasses. Not much sign of foxes except small footprints in the dust at the flat mouth of the stream-bed at Pearson's Harbor Aug 31 - Two in steel traps, both on storm beach (one in same trap as skunk last night.) Both females, both surprisingly small and delicate. U.S. looks adult, however, and boat station says the big males are little larger. Head one bark "just at daybreak, sounds very much like silver fox" (an irishold yelp). Urine smell also very similar to silver fox. Mother had any vertebrate remains in stomach - just fruits and anthophols (+ grass + cotton), (conorostaphylis + magnolia series) Sept. 1 - Another when in steel trap near mouth of "river" at Pearson's Harbor. In good flesh but even smaller than yesterday. Mouse hairs in stomach, but maybe lost. Sept 2 - One of the fruits in the fox droppings is possibly a red-bane Phatimus. The stems of this Phatimus were seen in a shrub stomach too [Conorostaphylis diversifolia]

Ranch hands that hunt them with dogs at night, apparently making kills frequently. A sow killed by them tonight had young with her. sept 3 Went up to look at the sow they shot. Quite good sized perhaps 70-100 lbs. One young black and white piglet was hiding under her stern when I walked up but scampered off when I approached to about 10 yards. It weighed [illegible] 3 lbs. or so. The mother had a distinct more of burlette. Her stomach contained about half by volume fruits of Opuntia; also acorn or Photinia? fruits, etc. Had a bit of the barn for lunch, -> Manganita sept 4 "Red" Crew, the ship captain and ranch manager, says when pines are abundant he has seen as many as 100 in a day. They never bother the lambs or chickens.

The ranch hands say there are still about 2000 "wild" sheep in the northwest part of the island. They claim they have killed about 20,000. Sept 12 Saw a family of 4 resting under a large oak in early afternoon. They let me come within 35 yards of them, ran off a little way, then stood at me, one of the ewes hollering at me several times. There was a ram, 2 ewes, and a large lamb Sept 13 Saw a pair of rams.

Benson 1948 31 Pomerene, Marin Co. Calif. Oct. 16 Visited the Coyorhinus barn 1 mi S of Pomerene in the afternoon. Found 3 carp with attre, quite awake and flew readily down the stairs and hung up into heater room. Shot 2 of them, the third got away. (Benson had reported there here 2 weeks ago. Both mine were female, both landed. Full noon, saw 2 kinds of bats flying at angle over edge of rush; one sp. was large, narrow-winged, fast flyer; other small, slow but rather straight flyer. Picked up a Pernygenus in damp woods at 4 p.m.. It was hopping rather casually over the leaves like a toad. Seemed sickly and had several fleshy net angular region. Went back to the barn at about 9:15 p.m. Many mystica nympanensis flying at bottom of stairs and in heater room, also spatious in main room. At least 8 were in a cruck behind a board on the stair landing. They had not been there in the afternoon. Shot several of them as well as one antrozona in the main room. In the middle garage downstairs were a few more Nn. nympanensis and 2 thysonodes which I shot. All these collected had full stomachs. Oct. 17 Returned to the barn about 10 a.m.. Shot one more Corynorhinus (unbanded) in the garret (perhaps the one that escaped yesterday). No other bats found. More behind board on landing where the nympanensis had last night. All bats of all species were fat. Oct. 20 Returned to Pomerene with Mary & Carl Koford and AKP et al. Went to the Rite-Aid Market and asked for Lewdi as per instructions. Lewdi was away but one of the other people working in the store [owner ?]

Rapped to be the owner of the bat barn we were looking for. The barn is just west of the main street of Immersion, many droppings in the attic but probably several weeks old. Owner said that only a few weeks ago there were “not hundreds but thousands of bats” roosting there. When we looked at 4 p.m. there was only one, a banded female Corynorhinus who escaped. Went back to the Golden barn 1 mi. S. of Immersion and caught one banded female Corynorhinus and about 6 Tadarida before dark. After supper (night hazy & overcast) found Myotis yumanensis as before. Also a few M. californicus. Checked again at midnight and 4 a.m., but only a few more yumanensis. Came home then around the north rim of the Bay. Stopped at several battry-looking places, but no bats. One very promising cluster of ledges near Black Point had only owl pellets.

(948 D. P. PEARSON 33 journal Sulbury Caves, 11 mi. SE Hat Creek, Shasta Co., Calif. Nov. 6 Left Berkeley supper time yesterday with aunt + Carol. Drove up q.q. W. to about 15 mi. S of Red Bluff. Camped in field about 10 p.m. where the first rodness starts. I had the good fortune to sleep a few yards from some burrowing owl holes. Just at daybreak 3 or more owls returned to these holes. Saw them flying and alighting near us and squeaked two of them to right over me. They alight on the ground in preference to fence posts and run like quail. The holes were dogger-size on top of a mound. Some had white droppings, and feathers in them, two had a pellet. One was red-colored containing insect remains, the other mammal but no skull. Left about 8 a.m. and arrived at Sulbury caves at lunch time. They are two caves (in reality one with an opening in the middle) accessible through a large creter. They are smooth clean tunnels, branched, looking like man-made tunnels big enough for a motor car, quite dry. 8 or 9 corycorhinus were hanging singly and conspicuously, widely spaced, from the ceiling. Two or three Eptteressa were seen in one cove but could not be dragged onto Caught 6 females and 3 males (random catch) and removed them. Then went hunting for other caves. Found two on the Rim Rock Road about a mile south of here. One was low-ceilinged, beset with moisture, had icel stalgwater but no bats. The other had 3 ? Coryphalin which I took. It was a dry cave similar to Sulbury but

P. PEARSON 1948 34 smaller. Went back to subway at 7:30 and put a pine cone under each Cory. Some Cops were flying, one Ophiacris, semi-torpid was on a cob wall near the crack where that balled before, and 2 semi-torpid Myotho seemed to be just emerging from a ceiling crack. Went back in at 9:15. A few Cory were flying and a few Myotho? looked like gennalensis, Many Cory had shifted positions. Caught a copulatory ♂ and ♀ (see 1362). Released the male. Caught another (or same) active male a few minutes later, but only removed the mated ♀. Most of those hanging were torpid, but about a half dozen had core unfurled or actually flew (total in south core at this time about ) plus 4 or more in north branch. During the afternoon saw numerous chipmunks & Collosperm. Several flocks of genn went over high, heading south. Mon. 7 Day just yesterday had been mostly overcast, occasionally sunny. Flurry of sleet at 7 p.m., shut later clear. Heavy frost. Car Car and milk bottles in car froze up. Went back into cars about 10 a.m. to check up on who moved. Had put pine cones under all of them at 10:30 p.m. Summary 5 ♀♀ not above cones. Vagina groovy in 2 of these cases. 9 ♂♂ above cones (here had not moved) & had been recorded as vagina groovy, other nothing mentioned. The latter and one other presumably had moved between 7:30 + 10 p.m., but not after 10. 4 ♂♂ not above cones (here had moved) 0 ♂♂ with cones, but in left-hand cave 3 ♂♂ had moved before 10 o'clock but did not move after

Total running 15♀♀ and 9 ♂♂ Removed yesterday /7♀♀ and 4 ♂♂/ 22♀♀ 13 ♂♂ About 3:30 p.m. we found that the left cave has a branch that goes past the rock slide that blocks it. This is much the longest branch of any; fairly warm and wet. In it we found only 6 bats: 5 ♂♂ and 1 flew. Here total score for both caves was 22♀♀ and 18 ♂♂ At 1 p.m. went cave hunting with a boy, Brent Parrish, of Rain Rock Ranch, Old Station, Shasta Co. Found one very good Corynorhinus cave a bit SE or E of the Ice Cave that we were in yesterday. Mostly females. Found one pair, ♂ and ♀, unweighted, both torpid. Clearly fluid could be expelled from ♀. Another cave 1.6 miles N of Subway had a very narrow opening and only one large chamber. Contained 1 Cory ♀. Went back to Subway in the evening. Only saw about 2 Cory flying in the course of 3 trips through the cave, yet considerable activity must have been going on (see below). Of the 18 we had spinned in the morning and hung up on the side walls, only two remained where hung at 8:30 p.m., about equal number on ceiling. (By tomorrow morning only 1 remain where put). At 8:35 on first trip through in evening encountered 3♀♀ clustered together. Captured them—all torpid). At another point (also in south branch):

P. PEARSON 1948 37 8:30 - 2 hanging together, not mounted, one awake, one torpid. 8:45 - 3 together, 1 other about 2 inches away. No copulatory motions. 9:10 - Same 2 together, look to look, both look awake. 9:20 - " " " " 9:40 - Only 1 left, a q with no signs of recent copulation. Saw no Mygmos. Perhaps last night's were right roosting and tonight too cold for outdoor flight. Mon. 7 Went back to Enchury Cave about 10:30 am (PST). covg. Counted 10 cov in south branch and 4 in north. Returned 4 males captured Mon. 6 to south branch and took 2 males from north. Didn't look in long branch of north tunnel. Thus, when I left there were at least 12 Cov in the 2 caves, at least 4 of which were males. The highest count in these 2 caves was 22 qq and 13 DD, of which I took 10 qq and 2 DD. Hence theoretically remaining are 12 qq 11 DD. at noon went back to "Parish" cave (300yds SE of Ice Cave). Counted 30 Cov look to where ceiling lowers to squat-level, probably missed seeing many because ceiling is rough. Removed 6 qq and 2 DD to take back to Berkeley. Mature say the road from Redding via Montgomery Lake is often closed in winter, but that one can always get as far as Old Elkhorn . from the north via Redding + Burney.

P. PEARSON 1948 38 Jackass Hill, 5 mi. W of Sonora, Tulame County, Calif. Mar. 12 Left Berkeley 2:20 p.m. with Anita, Mary Koford, and Haves Gray, arrived Gray's cabin near Tuttletown 6 p.m. Caught two Myotis californicus in the cabin (δ and ♀) and several others escaped. Also one or Corynorhinus in the Gray mine tunnel (The Relief Mine). After supper visited 5 other good mine tunnels on Jackass Hill (Chilena Mine, Mark Twain Mine, etc.) Found one more lone Corynorhinus δ and a pair of Myotis californicus. These were mounted, one almost smothered by the other, and one was a δ and the other ♀. The vaginal region of the ♀ was bruised and the skin of flanks red (from scratching by δ?). The penis of the δ was considerably enlarged and reddish, looking somewhat bruised. More of the above specimens were torpid. Mar. 13 Drove to Mercer Cave, looking in numerous abandoned buildings on the way. The "tourist" part of the cave is electrically lit and the owner was reluctant to have us look in other parts or in other shafts. He didn't think there were many bats - if any. It is a limestone region. Also went to Moaning Cave, but the entrances have been bat-proofed. Stopped at the Denamore Mine near Moaning Cave. The caretaker there, Mr. Hill, told of a tunnel and stope at the Goodwin Dam near Knight's Ferry, where he used to dig bat guano and sell it. Drove there and found the place, a long tunnel with occasional heaps of guano and a large stope with much guano. Only one male Corynorhinus, δ in the tunnel.

Arrived Old Station about 10 a.m. About a foot of snow on ground and light snow falling. Went into the small cave 1.6 miles N Sulphur Cave (see Nov. 7) & where I got 1 Campylophilus Nov. 7 but no bats now. Outside temp. -1° C., inside -5° C. Went next (11 a.m.) to "Parish" cave 300 yds. SE of Ice Cave at Old Station behind the Twin Rock Ranch. Came to a cluster of Campylophilus about 50 feet in where temp. lowest-high was -4° and -2° at ceiling where bats hung. From here in were, many Cory hanging singly or in clusters of as many as 31². This cluster of was hanging from the ceiling, close unfurled, where air temp was -1° C., temp. in center of cluster was 0° C., all these and others in the cave turpid.

P. PEARSON 1949 association or segregation of bats. Hung up all banded ones on walls or ceiling, but several were flying when I left the cave (about 1/2 hrs. after starting to band). Went into the 2 Ice caves but no bats. Temp. far in was -2° C: icicle, no water. Lunch in bright sun on snow, but temp. below freezing. Then went to Dudley Caves. In North branch found following: 8 single Cory, many with ears curled, in the left-most chamber. None in other parts of this north section, not even down the long tunnel beyond the cave-in. Temp. back thru long tunnel was +9°: Marked location circles etc. the 7 torpid bats. In the south branch Cory was hanging from the high ceiling of main cross-tunnel and in the left-hand chamber. In this chamber were clustera of 18, 6, 5, 2 prs., and 23 singles. Marked their location by chalk circles etc. Although Also three in high-ceilinged cross tunnel (4, 2, 1, 1). Also 2 Myotis subulatus on ceiling about 1 ft. apart. Removed them about 4:30 went to see Brent Parrish and he showed me a new cave on the [illegible] Loop Rd. Opening on top of a rise, probably about a quarter mile S E of Ice Cave. Slept by camp fire in snow. Clear, calm, cold, full moon. At 9 p.m. checked locations of bats in north branch and in cross-tunnel of south branch, but didn't go in the south chamber. Two new single Cory had arrived (or appeared) in no north chamber, and a pair in south. The top member of (dorsal) of this [illegible] pair was awake, the bottom torpid. Tried to net them but the upper escaped. The lower was a 9, no sex apparent.

P. PEARSON 1949 at about 10:15 p.m. no further move had been made. Slept in "middle" chamber of north branch. Jan. 15 In morning some change had occurred in north branch (see Maria notes) Dandel remained. In south-left chamber (unstudied all night), 5 singles had left their original places, the large group of 15 had dwindled to 13, one group of 6 had enlarged to 14, and a group of 5 had dwindled to 1. The total number of bats in the chamber in a.m. was same as yesterday afternoon but of the 56, at least 17 must have moved during this night. Both 32 and 44 had moved. In the high-ceilinged cross-tunnel a group of 2 30's and 2 40's had not moved, a pair (8+9) had not, and 1 single had arrived. Temperatures in a.m.: outside, -2° F; left chamber of north cave (where bats hung) cont[acted] 0°; left chamber of south cave +1° c; high ceiling of cross-tunnel, -2° C. Looked into the south cave that Parrish showed me yesterday afternoon. There were two tunnels, one about 50 ft. long, the other 100+, both open at both ends. no bats. [Simen Zehol on topo map] [Simpson fork] Stopped at the store at Maa/boatchs to ask about other caves. Was directed to the Bidwell Ranch which is 3 or 4 miles back the road east of Mashooatibe. The last unmarried daughter Bidwell took us along the bottom of the river in search of a couple of ice caves that she had found in a dozen and a half times" but failed to find them.

Then drove to the Pit I Power Station on the Pit River 1 1/2 mi NE Burney to investigate some tunnels in chalk cliff. Picked up a boy, Danny Shipley, who directed me to them: along the road that goes past the tennis court near the village below the power station. The tunnels (3 of them) are cut out along the road a few hundred yards downstream from the tennis courts. Found 2 Cory's tarperd in the nearest of the 3; one of the Corys loaded with moratuus. Danny says he has found bats on the floor of the tunnel underneath. Then home. arrived 1 a.m. left Burney about 6. Mipple sizes of HF from this trip: tiny 18 small 7 medium 9 large 33 If this is a x-section of population if mipple size is a good age-character and if sex ratio is 50-50, then the 18 tiny (young) must have come from > 33 large (adults), hence medium-mipples must be adults. These 33+9 = 42 adults probably didn't raise 18+7=26 young, so it may be that small mipples are adult also. :: 50 adults and 18 young.

Didn't move or disturb any slept took down a few unbanded Cory and 1 Mysteta subulatus. Also took 2 ?? and 1 cory (unbanded) from south branch. More were in the other parts of the south branch. Slept in north branch. Feb 3 Road hard in Dulbergy. Took more Cory from south branch and 1 more subulatus. Temp. in the left (bot) chamber of north branch 38° F; in left (bot) chamber of south branch 39° F. No bats flying or awake during this morning visit, but at least 2 were awake in the north branch when we went in at dusk yesterday. Left about 10 for Mader region. Road with about 4 mile new snow. Temp 28° F. Stopped at 1 Bella tunnel between Burney and Pitt River Power Station. No bats. After several stops to inquire about roads, arrived Mader Lava Beds National Monument about 4:30 p.m. Well over a hundred deer along the road between Burney and the park. One buck with antlers. Near Dulbergy saw Porcupines, Dipso Deer, Coyotes, Redbet Turke. Near 6-mile Hill saw Deer tribe, Road Coyotes in several directions, and saw 1 another hare. Talked to store-keeper at Madercoatche, who mentioned a colony of bats living on the old flour mill at Alder. He found a large (15 " wingspread) grey bat [dammin?]

P. PEARSON 1944 near Moacoatche Stopped at the headquarter in National Monument after looking in Mammoth Cave (no bats). Mr. Don Fisher, the Superintendent, welcomed us and reported that there were no bats in the cave. Looked through several before dark Indian Well, Muchpoot, Polyrinth, and Cory in Polyrinth but not in others. Slept in headquarters building. Morning very high wind, much snow blowing and probably some falling. Went into several more caves: Thunderbolt (which connects with Polyrinth), Catacombs, Lateral, Indian Leg, Four Cory in Indian Leg, two of which we found and released in Muchpoot, and a total of Cory taken from Lateral and Thunderbolt. At least 3 others seen over a high ceiling but out of reach. Benson saw a Myotis subbulatus hanging bat awake in Thunderbolt. It took off and flew in front of us until we came to a rock entrance to the cave, whereupon it ducked past us and was not seen again when we retraced our way through the cave. Wind still high at noon when we left, temp. 28°. Stuck briefly in a few snowdrifts between Monument and Twelake. Home via Doris and Redding at 11:30 p.m. Four of the Thunderbolt cave bats died en route. Others OK.

one cage at 9:30 this evening for feeding, a Cory was hanging (awoke) on the outside of it. All the caged bats were present and accounted for. For the following reasons I am almost certain that this bat was a wild one attracted into the Pearson basement by the caged bats: 1 It was a very gray specimen, much more so than any of our Shasta + Dickinson tree specimens. 2) It had several parasite flies (we have removed the parasites from our captures as we feed them) 3 all captive ones are accounted for. 4 Ventilating gaps in the brickwork could have admitted it. If so it is the first Berkeley specimen of Corynorhinus. Only possibility of error is that it is a Shasta or Dickinson specimen that escaped when we first arrived home a week ago. None were suspected of having escaped, however. Specimen 1468. Orcida, Contra Costa Co., Calif. Feb 19 Mary Koford and I put #20 Benow live traps baited with oatmeal on water company land in an abandoned circle on the north side of Bear Creek Road about 2 mi. east of the Orcida-Richmond highway. The thick grass and thistle habitat looked good for Meristus but saw no good recent tunnels or droppings. Set about 3 p.m. also 50 Sherman in grassy field in NW quadrant of Orcida crossroads. Said to have been many Meristus in Orcida region last summer, but saw no clear recent tunnels. Very little green vegetation.

Then drove to Muir Woods in rain to look for bats in hollow trees. Looked with flashlights in several dozen burned out hollow redwood trees. Many of them dry, dark, and cozy, but few with large enough cavities to house large colonies of bats. Saw numerous moths and spiders but no bats. Checked the San Quentin traps at 2 p.m. and found 1 Micerotus and 1 Jorep (dead). Many droppings, cut pieces of Salicornia, and runways in both places.

P. PEARSON 1949 52 Pat River Power Station, April 2, 1949 April 2 left 6:30 p.m. yesterday with Dwight & Mary + 3 bats for Parson. Left out between Red Bluff + Balding, but rained so left early 5 a.m., arrived Dabney Cave 8 a.m. No bats at all in north branch; considerably better than before. In south branch found a few at crossroads and a few in left chamber, but not nearly as many as on previous visits. All bats seen were banded. Re-weighed those weighed before: average loss about 0.5 g. Temp in left chamber 50°; at ceiling of crossroads 48°. Mycotic contamination. In Parson Cave the bats were fewer than entire than on last 2 trips: none look even as far as where the flash-light photos were taken. Considerable ice on ceiling this morning, and it a snowy sort of snow, some of which had fallen to floor. I believe this was the form in which it was removed commercially. Many fewer bats here than before, almost all the females large nipples. Banded about 4♀♀ and a couple of males. All except 1 of the females had large nipples; all except about 4 were banded. No bats in the two caves. Brent Parson said it crowded last night, but chipmunks + hawks were out during day (50°). Temp in Parson Cave where there were both bats and ice on ceiling was 46°.

P. PEARSON 1949 Looked in the oven kitchen at Acta Springs. About 60 Cory there, mostly in 2 clusters. Awoke quickly. One male, rather torpid, hanging by himself. Caught one cluster which was all ♀♀. Landed about 10, and released others ¼ mi. down the road. Many landed repeatedly on trunks of scattered oaks. No banded bats caught or seen. Stopped at Angwin but no bats in either winery building. Appendix: Lucerne Thysanodes band numbers: 446-16831, 446-16839, 46-16891 San Quentin, Marin Co., Calif. april 17 left 4:30 p.m. with Bob Lewis, Set 130 Sherman + Benson two-traps in Dalecornia and Dalcornia-grass. Batted with oatmeal for Microtus, finished setting about 7 p.m. at 9:30 had 6 Microtus, despite fact that marsh was much drier than previously and with no really fresh droppings or cuttings. 5 of the 6 in the east end of the north marsh - which has consistently been the most profitable terrain. at 8:45† caught one Myotis gurneensis hanging (but not yet torpid) from ceiling in west gallery of brick kiln. Saw no others. Looked in center “five-chamber”, a long tube accessible by 2 man-holes on top of kiln, but no bats. Seems a good place though. No more bats at 10:30 p.m., but saw 2 flying in west gallery at 2 a.m.

D. PEARSON 1949 56 at least one of these seemed to be larger, darker, and a straighter flyer than yours. No more bats at 5:30 a.m. and only 2 Rippers megalothe in traps south of road. No more meistras. Forgot to mention 1 Mrs by Ienia far out toward bay SE of road last night. April 28 left 7:15 a.m. with auto, infants, + Mary for Actros Springs. Arrived 10: and caught 48 T Coryphorhinis in attic over kitchen. Only a few escaped. Banded 32 and released them in attic, brought 16 home for testing rate of development of fetim in warm and cold rooms. Up the road about 1 mile are the Actros Muira (screwing), we were shown into one tunnel where the co-owner saw bats flying "like a swarm of bees" last June+. There were no bats present. Several other tunnels were boarded up or we were told they were "not open": In any event, these tunnels so near a breeding colony offer a good possibility for keeping track of a colony all year round. No [illegible] bats in Angwin nursery. May 5 left 4:30 p.m. with Holt Bailey for San Quentin. Set 44 Benson traps and 90 Sherman boxes with oatmeal for meistras. 94 of them in Labormia north of Road at San Quentin and rest in grass at Corte Madera, at 9 p.m. had caught 3 meistras in S.A. line, didn't check others. One Antozymus night roosting in brick barn at 8:30.

PEARSON 1949 57 May 6 Hunted red-wing blackbirds etc. beginning at 5:30 a.m., then picked up traps about 8 a.m. 9 more Minerates, several of them young, and one Mice [all in Solomona]. Mr. Kenthaadventuringa. There done to implant redwing/falubaris. May 29 Left 6:45 a.m. with May Koford aunt, et al. for actua springs. Left aunt + children at Putah Creek (via Vacaville). No bats in other over kitchen at actua springs where we collected and banded April 28. Many vocatoven and much noise in kitchen below may have scared them away. Manager said many showed up in the socialhall a week ago, but he drove them out with aerosol bombs. Then looked in furthest of two tunnels at sharp turn of road at actua mines. This one had contained no bats April 28, but today had 1 torpid Cory. The other tunnel, which we had not been shown before, is about the same depth and had one cluster of Cory with young. Caught all except 2. [illegible] of them were unbandled, 30 of them were from the 32 banded over the kitchen April 28. Most had nursing young, a few late preg., and one not rather preg. nor nursing. For composition of cluster, size & ratio of young, etc., see notes of M.K.

P. PEARSON 1949 58 may 30. one of the 2 pregnant females caught yesterday was restless and moved around the cage considerably from 9 to 10:30 am. [caymanas new / preg - act / moving q], at 11:26 she was hanging from top of 1/2" wire cage by both thumbs and both feet + see top view -> [illegible] The tail was curled up and forward and the membranes arranged in such a way as to form a basket. A young had been born and the & mother was licking it rapidly, as well as licking her own tail membrane. This lasted at least 3 minutes. The young made no sound although it was moving around some and one hung by its hind feet from the cage wire. The head was buried all the time in her left axillary region, where presumably it had a nipple in its mouth. At 10:40 the mother was still in this position, but not licking - looking around. The young was quiet and not moving. The mother was next to the other two q-f but not quite touching. They were asleep. At 11:57 she was in some position and again licking the young, which again had 1 foot looked on ceiling. No drops of fluid visible on paper towel on floor of cage. At 12:10 mother hanging by hind feet only, back touching other 2 q-f. all quiet. A 4.4-g. young makes a sharp, high-pitched, metallic chip that reminds more than of chimney sweeps

P. PEARSON 1949 59 June 4 Left 4:30 p.m. with Anita, Mervy Koford, et al. for Aetra Mines. arrived ca. 7 p.m., talked with Mr. Hertz (the mine owner), and looked in various tunnels for the banded bats. They had moved in toto to a tunnel about 100 yards up the hill to the north of the 2 shafts by the [illegible] turn in the road, Didn't check them other than shining light on them briefly from a distance of 15 ft. Effored for more tunnels till dusk. Found one about 1/2 mile N. by road in which a Myotis evotis & was flying. Saw numerous bats flying at dusk, one small species quite early. (1) Called by me West Tunnel. Straight, dry, caved in after about 100 ft. Has date can be seen from road. (2) " " " East Tunnel. " " Dead end. " " " " "

P. PEARSON 1949 60 3 opens under maple tree in crater. Only about 15 ft. long and light looks in at south end. No bats. 4 opens directly up hill from 3. Enter into large, high-ceilinged chamber. Another glory-hole opening and short deep shaft. Fairly dark but no bats. 5 Reached by walking up gulley between 3+4. About 100-150 feet long, straight, dry, partial cave-in at end. Has bats called North Tunnel. 6 Reached by following old road about 1/2 mile. Entrance boarded up with "Danger" sign. Forked, one fork blind about 75 feet, other fork with deep pool & reaches at least 100 feet. Has bats. 7 Have not seen yet. Described by horse-back rider who had just past it and had seen 2 bats flying at its entrance. He called it a "cave" because no mine dump was visible. Presumably it is easily reached from some bridle path or such along the bottom of the gulley. 8 Visible from road below the turn. Entrance boarded up. Haven't been in yet. at 9:30 p.m. looked into North Tunnel hoping to find out whether or not q+q left young behind when they went out to feed. Cluster of adults + young was hugging at same place. One young < 1 week old was separated from cluster by about 1 inch but didn't stay to examine closer for fear of scaring all away. Caught 1 & Mystus gymna, and 1 more & Mystus evotus in East and West Tunnels at 10 p.m. looked again in North Tunnel at 11 p.m. Cluster of adults and young still there. The young one seen before no longer separate.

D. PEARSON 1949 61 June 5 Collected all those in the cluster in North Tunnel. Saw some escape although one was seen flying afterward but not captured, checked band numbers etc. For details see notes of MK. About 2 were still preg and 1 (same) was non-preg non-lactating. Twelve were carrying the same babies as they were last week and 2 were not. Loose babies we put on floor of cave about 10 feet further in than where we were banding at entrance. All except one crawled immediately to climb up the side 1/2 to 3 feet. One into a crevice. They squealed occasionally, which attracted the attention of females that were flying about from time to time. All 4 seen flying were not carrying young. Baby bats not squealing audibly were not approached by females. There seemed to be a tendency for the babies to squeak more when the FF were nearby. Perhaps the babies hear supersounds but attract the FF with audible squeaks. On 6 occasions females came up and selected a baby, crawled over it "brooded" it for perhaps 10 seconds, then flew off with the baby attached. In each case the female rejected one or more of the babies after a momentary contact with it, then encountered one that gave every indication of "satisfying" them, and flew off with it. After several attempts, Mary finally settled one [illegible] after it had picked up its young. The baby was one that was unattached when we sorted out the catch. The female was one not in the catch I parts possibly

seen the one flying after setting the cluster]. The baby had been put on the wall in contact with 9 others. The female came up & landed "looked over" several, then covered one of them with her body and wings, making motions as if tucking the baby in. Mary said it was obvious that she was trying to have it attach itself. Mary caught the ? and attacked young just as they took off. Out of 10 young of similar age had chosen the same one that had been attached to her last batch she had been carrying when I saw her last week. The mothers were able to fly with today's youngest young attached (6. ) g. June 9 left 6:15 p.m. for Lassen with Anita et al. Slept at burning owl place south of Corning - but no owls. Saw several barn owles over rice country. Drove over Mt. Lassen via Red Bluff and Minned. The road opened May 30 this year, which is unusually early. Stopped along the road 5.9 miles south of Old Station at a very large pile of lava blocks a hundred yards or so west of the road. This is yellow pine country and about 5100 ft., but heard at least 2 cornes. Went into Lahway Caves about 5 p.m., but no bats. At 9 p.m. 3 or more large bats were flying inside the cave and in and out of the tunnels. Went into the tunnels and saw flying 1 corn? and 2 mystic? but nothing hanging. Temp in North Branch (with lantern) 7.6; in blind chamber of South Branch 6.8;

P. PEARSON 1949 63 June left at Caves Campground along Hot Creek. Several small bats flew early dusk last night. This morning a dipper was feeding its young along the stream only 15 feet from our sleeping bags. A single parent was attending a single young, which appeared as large as the parent. The young could fly, swim, and feed in shallow water. It kept up a high squeaking accompanied by bobbing motion. The parent did most of her feeding along the edges of the creek, but occasionally dove out in the middle; a little later it developed that this parent (or another) was feeding two young. Looked into the 2 Ice Cave and Parrelh Cave and the single chamber cave 1.6 mi. W. of Subway. No bats in any of them* but considerable ice in both Ice Cave and some in Parrell Cave. Drove to Cassel after lunch, looking in barns on the way etc. Only bat seen (and collected) was in the attic of the big house at Cassel (a * Corynorhinus). It was awake enough to fly. Camped at the Cassel Creamery. Several night hunters hunting over the lake at Snake and many bats—sometimes 2 dozen right at once. Started night hunting about 9 p.m. and did 4 collections in the creamery and in the big house. Many Myotis young on each trip, especially in the upstairs hallway * of the big house and the refrigerator room of the creamery. As many as 25 in the latter at one time. Stored all in butter tins and socks overnight.

P. PEARSON 1949 64 June 12 Banded and released about 75 of the Myotis yumanus. Pint up 5 and discarded 2 injured ones. While banding me found 3 day-roosting in the big house. When released most of the 75 flew airlessly, after landing on the side of the big house. Several crawled with confusion without hesitation under the trim of the clapboard big house -> After lunch drove to the Hot Creek Power Plant No. 2 which is 3 miles north of Carcel. People at the Carcel store had said there were bats in the gorge there. The garage is a high-roofed, girdled structure with corrugated iron roof. Bats were roosting between some boards and the corrugated iron. Caught one of them (a Myotis yumanus) and several others sticking their heads out but decided not to try to get them. Then drove to the 3 chalk tunnels at the Pit River Power Plant, 11 1/2 m NE of Burney. Nothing in the tunnels at 5:30 p.m. but at 9 p.m. cought 2 Myotis [illegible] and 1 Eptesicus. One other Myotis? escaped me. Didn't see any bats flying at dusk. June 13 Skinned bats + painted. Drove to Old Station at supper and talked with Brent Parrish, but he had no good ideas as to where the Cory are. Camped at the Cory - Bee place 5.4 miles S. of Old Station. Cories continued calling until

P. PEARSON 1949 65 9 p.m., which is long after dark, a few bats flew at dusk. June 14 Drove east on the Lawrenceville road to look at old buildings on the topo sheet, particularly Grace Lake, Lingley cabin, and Cora & Ward Ranch. Much bad road, no bats, and in fact, practically no remains of cabins at 1st place. Lunch at Cora & Ward Ranch, then started home. Home midnight. June 29 Left 2:30 p.m. with Anita, Mary, et al. for Acton Springs. Arrived 5. Looked in all known tunnels at Acton Mines but found only 1 ♂ Cory [in Tunnel 6 opposite of June 4]. Also found the tunnel 7 mentioned by the forelock roller. It is in the gulch on the north side about 300 yds downstream from No. 6, has considerable water in it. Also another tunnel at the head of the canyon just below the owner's house. Then looked over kitchen at Acton Springs and there was the entire colony, despite noisy dish-washing for 80 guests down below. We left them undisturbed, had supper, and returned before 8. Many Cory left before dark, but observations were confused by many other bats emerging from behind the chimney (creek between chimney & house). Emergences slowed considerably about 8:15, and Anita & Mary went into attic about 8:30. Some adult Cory and many young Cory present, some of the latter flying. Considerable traffic in and out of

"window," but some confusion because antrozous was coming in to night roost. I joined them before 9. at 9:40 Mary's impression was that only young cory and night-roosting antro remained. at 12 when we left, there seemed to be fewer young cory, and we went to bed thinking that the mothers had returned only by one and carried them off. [at 10:4 both came in windows followed by chittering of babies] June 30 Returned to attic 8 a.m. The entire Cory colony was present in 2 clusters. Captured all except 10. Most or all of these recaptures were banded once. Of those caught, all except 1 small one and 1 adult ♂ [sic] were banded. The unbanded baby may have been this from the single preg. I lost most. Kept the ♂ and 2 mothers and young. Most of the young were within 10% of adult size and all except 1 flew when released. This non-flyer was not the smallest [123030]. No antrozous seen. Home 12:30. July 2 Left 6:30 p.m. with Anita & Peter for Pine Crest to pick up captive measel. Slept east of Knights Ferry. July 3 Arrived Deer Survey Camp at Belle Meadows before lunch. Survey crew was off on hike, but Bernie Rhiney told him They saw 5 measele cross road at night and managed to catch one half grown one in his hands. Set 11 traps baited with minke food at the place [many fallen logs among fir & sugar pines about 4 mi. by road S of Pine Crest. Then lunch with Bernie, afternoon with Leopolds

PEARSON 1949 67 at their camp. After supper with Bernie and her comps-mate [ Joan? from near Hastings reservation ] we all went jacklighting at the neesed place . Saw nothing. July 4 Traps held near Longyearz and 1 Meretue [ in woods ] along stream. Home about 10 a.m. after looking for bats [ none ] in mine tunnel on North of road about 1/2 mi W of Longear. July 12 Left after lunch with Anita, Mary, et ali for meals at Guetino + Nemman. Much driving around these towns. Set traps at dusk, 1 at Schoolhouse between Nemman + Guetino and 3 near our sleeping place on a road running east about 2 mile or 2 south of Guetino. This road runs through flat unkempt -looking country and marshes. Many jack rabbits, some mosquitoes at dusk. Drove about 40 miles after dark on roads around Guetino and saw 22 jack + bunny rabbits, 1 young opossum (about ground- squirrel size) and 1 Meretue. The traps set more new wooden meal traps. July 13 No traps springing. Up & down and drove more looking for meals around Guetino-Nemman. No traps springing. Talked with numerous people. Heard and smelled bats in Nemman in an old brick building at corner where road to river branches off main road. Bldg was being used for storage by Simon Nemman. Saw 1 Mered ruin in p.m. Set 4 wooden meal + 5 Harbert traps along the same marsh road as last night. Slept in wheat field east of Nemman Guetino.

P. PEARSON 1949 68 July 14 No trips spring. Home 10 a.m. July 22 Left 8:15 a.m. with Mary, Pitler, and Dr. Esteban for Napa Co. Comperthina. First to Knowville where we looked in 3 tunnels. One steep tunnel with "debris" over it, skipped shaft entered by ladder. I went down about 75 feet and never did see bottom, no bats. This one (3) was up on hill. No 1 (no data) was on hillside behind abandoned house, and No 2 (one awake & cory) was just along road to Lower Lake. (1) Dr. caretaker here mentioned more tunnels 4 miles up right fork of road (which later returns to lower lake road at Reiff) so we drove there, a location known as Reid Mine. The manager said no bats in the tunnels & crossed out near the headquarters but referred me to 3 further up the road. Two were a few hundred yards back an old road (blocked) to the right of the road about ¾ mi. N of the headquarters. (One of these was a good tunnel but no bats. The other was more than half full of very murky water, we didn't go into it). The other tunnel had a narrow opening at the left edge of the road about 1¼ mi. above the headquarters. In this tunnel, which had several short branches, we caught 2 active & cory and 2 torped & f. Thus all 308+ bats were awake, both ff torped. Home 7:15 p.m. via Argentin & Pope Valley.

In minery at Angwin many Antrozous in old building, Mr. thyzander under tin of roof of cupola of old building and clustered on rafters in 1st floor of stone building. Also 2 Cory in 2nd floor of stone building. Krutzsch left about 4 thyzanders, 2 antrozous and the 2 Cory. Home 2 p.m.

Pearson 1949 journal Aug. 8 Big Lagoon, Humboldt Co., Calif. Left Berkeley 5:45 a.m. in Dodge with Cogswell; Miller, Murray, and Sullivan in other car. Route 101 all the way to Big Lagoon where we arrived about 6:15 p.m. Only mammal stuff en route was at Benbow Hotel where Cogswell and I took a quick look in the stable for bats. People + horses were living in it, saw no good bat places in this building. Set out 70+ museum specials baited with walnuts in thick grass, weeds, + salspina on east edge of lagoon where ranch road crosses creek. Saw no runways, droppings, or cuttings. Many low-flying small bats at late dusk over ranch road between forest + Lagoon. Also put out 2 steel traps unbaited after dark. Aug. 9 My traps in March held 3 dormice and 5 Zapus. Cogswell along brushy edge of spruce woods caught Pero and Sorex trowbridgii; Murray Peromyscus. No microtines! Looked in ranch buildings for bats but few good places for them. Underneath ranch house seems satisfactory for Caryophs but nobody home. Put out 50 Sherman live traps baited with walnuts along the log "wall" below the big log pond - mostly on the edge of or in thick salspina. Saw one set of Microtine? droppings there, also 3 raccoon sets along stream and 3 other steel along log "wall". Also set 35 Museum specials in smoggy gloomy spruce woods baited with walnuts. Sullivan set 33 in same sort of place.

O. P. PEARSON 1949 2 Jacklighted till 10 but saw nothing except bats, 1 Pero (robased) and 1 Boar in live traps. Aug. 10 Out of about 125 traps out got 2 new species: Retheringtonia and Sorex pacificus. Threw out 3 L. rogana, 1 trawbridgei, 7 Peromyscus. No disturbance and no bait removed from steel traps. The Scirpus marsh yielded no Mice ates, in fact the only one so far is an immature Microtus longicauda? from Cogswell's line. Picked up the last of the traps in East marsh and put them into Scirpus marsh, baited with oatmeal. I get the impression that (judging by droppings) mice are attracted to the places where cane have chewed off the Scirpus and the new shoots are coming out for a couple of inches. There are very small droppings. Traps now out: 50 Sherman in Scirpus, +40 Museum Specials in Scirpus, 7 steel; 6 Schuylers in Scirpus, 33 Museum Specials in Sphene-fern grass. Aug. 11 3 Mice at last - in oatmeal-baited museum specials in Scirpus marsh, all M. longicauda. Nothing in steel traps and nothing in the Schuylers - some of the latter are very nice rabbit-sized runways. Two more Zapus in Sphene-fern grove, one of them in an almost pure fern stand with practically no grass or edge within 5 yards. Otherwise more Peromyscus, Sorex rogana & pacificus. Much skining. Set out about 15 museum specials with oatmeal in dry grass meadow SE of camps and 7 Schuylers + rat traps around 2 wood rat nests. Threw out 6 Peromyscus, 1 Sorex pacificus, and 2 trap-caught song sparrows and 1 young thrush from trap in Sphene-fern. Trap lines have not caught much during daytime.

O. P. PEARSON 1949 3 jacklighted across marsh and around Scirpus but saw nothing. Bats were skimming log pond at 9:00 and 9:45. Set 1. Aug.12 Picked up the traps in Spruce-fern grove, baiting them with oatmeal yesterday may have accounted for catching 2 Merstua oregoni in the middle of this thick woods. also 2 S. poicilos and 2 Zapus and 1 Peromyscus. A racoon? had disturbed about 20 snares and two traps in the Scirpus but didn't go near the behinglers or steel traps. This Scirpus line caught 3 Peromyscus, 1 Merstua longicaudus, 2 Zapus, and 1 song sparrow. 2 woodrats up the road to its east and 1 Peromyscus. All 3 raccoon sets along the river were sprung by coon, hair left in one and a toe in another. Reset them at different places along the river in pairs. Nothing in the dry pasture traps. Threw out 5 Peromyscus, 2 poicilos, and 1 Zapus. Having picked up the Scirpus and Spruce-fern traps, put out about 30 along a stream in big redwoods east of the lumber camp. This is gorgeous redwood with thick fern, rotten logs, moss, etc. Floundered out of the tangle after dark. Aug.13 Redwood traps had only 4 Peromyscus manic, 2 Zapus, and 2 Sorex poicilinus. Set the rest of these 50 in the redwoods. Looked in 5 big hollow redwoods for bats; none. Set around 2 more woodrat sets making a total of 4 now. Only one mouse in the dry grass-thistle meadow, a Merstua oregoni. One more Nestoma from some home - a smaller one, here 3 mice at some house. Raccoon traps untouched,

O.P. PEARSON 1949 Aug 14 Only mouse (zapus) out of 50 traps in big redwoods. Probably this hive. Two more wood rats and a skillogalee at the woodrat nest, also 1 Myotis longicauda in the dry grass + thistle a few feet from M. Oregoni yesterday. Evening was cooler and muddier than most. Myotis flight sponsors and later than navol. Noted out, Aug 15 2 Myoturus and 1 Jones poeferis. Nothing in gross-thistle, Shot a Sylvisyne bochuerani at 7 a.m along road south of camp. Then drove to Eureka to have truck fixed. Several hours shopping bathing, and sightseeing in Eureka. Two points of interest in Eureka are the Carson home (the 1865 gingerbread mansion, beautifully kept up, of a lumber Baron) and the old abandoned Gunther mansion on an island a mile or so out into the bay. The latter looks from shore like a gorgeous bat locality. Home 7 p.m. Aug 16 Jacklighted after supper. Heard woodrats and saw cat-size eyes on road at bridge east of camp but couldn't get near it. Aug 16 Only trapped specimen 1 Myotis longicauda in dry pasture of grass-thistle, also 1 very rare M. Oregoni near it. Drove from Big Sogoon to Mod River, stopping at all likely looking bat roosts. Best ones were Big Sagoon Bridge, abandoned store in center of Trinidad (Trinida), and mod River Bridge 4 mi. N of Arcata. Only the latter had any bats, all Epttarius

O. P. PEARSON 1949 5 Put 3 mink sets in marsh below log pond, 2 of them where Squirrel shot at one yesterday. Evening cool, clear, few bats feeding near spruce but several out over pond. Aug. 17 No mink in traps. Set 4 more, making 7. Also set 44 oatmeal-baited museum specials in short grass along in marsh below log pond dam. After lunch drove with Murray up toward Kane Ranch where Cogswell had reported grown young redwoods with woodrat nests at the bottom. Stuck the truck while turning around so Murray set the woodrat traps while I went to Kane Ranch for help. Spent rest of afternoon trying to extricate trucks. Aug. 18 Up early to hunt night hawks + bats, 4 night hawks were circling over the lower Maple Creek bridge and headed south without circling any more at about 5:35. The last bats had disappeared before this, heading toward the woods to the east in remarkably straight flight -- 50 yards or more without a swerve. Nothing in 46 traps in short grass in marsh, nor in mink, weasels, and woodrat set near camp. One Spilogale in Schuyler in clump of young redwood up on the hill toward Kane Ranch, and 2 woodrats nearby. Put about 25 oatmeal-baited museum specials along 2nd stream north of lagoon. Dirty loam along the stream with small spruce and alder. Not really gloomy forest.

O. P. PEARSON 1949 6 Spent the night at Trinidad looking for bats. Saw none in the old store at the crossroads at 9:30 p.m. but some flying in attic of the old Holy Trinity church at various times between 9 and 11. Because of great numbers of 1x12" roof supports and several holes in the roof, shooting and setting were difficult. No specimens. Checked buildings again 5:30-6:00 a.m. but saw no bats. Aug. 19 Looked under north end of Wood River Bridge again and found 5 Epterenius at 6:30. Several other nicely timbered bridges had nothing. Trapline along stream in sparse older woods north of Big Jagoon Bridge had 2 Peromyscus maniculatus, 2 Zapusia, [illegible] 1 Sorex trowbridgii, and 1 Sorex terdini. 46 traps in short grass in marsh again caught nothing. No marmots or cows either. Left before lunch for Orick, thence southeast up to the bold tops or "prairies". Now camped at French Camp, 3100 ft., near one of the prairies and amid Douglas fir plus some incense cedar. Put out 50 museum specials along trickle in meadow, through clear-floor fir woods, and in broken clearing. While setting saw rabbit droppings, gopher droppings, long straight [illegible] mole tunnels, deer droppings, lead chipmunks, and saw 1 tree-mouse nest: Saw one bat flying high and fairly straight east at early dusk, too large for Myotus californicus. Others in camp saw a few others. Traps started snapping at bat-flying time and I took 6 Peromyscus out of my first ten traps before 9:30 p.m. One trap went off about 7:45 followed by a few agonized squeaks audible 75 yards away. Probably A. fuscovacca.

O. P. PEARSON 1949 7 Jacklighted along the road and shot one brush rabbit. Saw nothing else. Aug 20 6 more Peromyscus in my line and 1 Mustela. Hunted down the road for about a half mile and saw many chipmunks; shot 1. Deer tracks in road, and ? tracks? Left traps in same place and set 5 traps for mole in Douglas fir. Drove after supper to the Fullwood Ranch (about 2 miles east and 1 mile down toward Redwood Creek). Missed house and farm but no bats or obvious droppings. A water tank we hoped would attract bats at dusk but saw only 2 or 3 and were unable to net or shoot any of them. Jacklighted 2 Mustelas near spring. Shot 1. Aug 21 1 Clethrionomys, 5 Peromyscus, and 1 Vespertilio sp. (at an opening in mole tunnel). Drove Miller to creek at 7 a.m. and stopped at about 15 hollow trees on way back. No bats. 3 very suitable buildings at Sage Prairie but no bats. Many chipmunks, ground squirrels. Also stopped at several other barns but no signs of bats. At Lyons Ranch Mrs. Lyons said she has seen numerous bats flying, but mostly later in the year. She remembered another group of people collecting birds + mammal here many years ago. Put out about 20 more Museum speckle among the moss-covered rocks in Pinyon fir where Clethrionomys was caught. One bat seen at late dusk; large, straight flight. Jacklighted west along road. Shot at certain carnivore ? eyes

O.P. PEARSON 1949 8 Aug 22 in broken down road. Sound of slot flanked corey of just out of young Doug fir and one Peromyscus at my feet. One more Clothronongs, 5 Peromyscus, and 1 young Meotus in traps. Left after breakfast for the big prairie around Schoolhouse Peak. Set 49 oatmeal-baited Shermana and 6 Museum Specials mostly along a wet sedge seep but a few out in grass, the edge about 100 yds from a torqne of oaks in a ravine. Watched ground squirrels and Murray I found 2 Myotis erebus in rock crevices. Put out two gopher traps around camp and caught one before supper. Early supper and drove with Murray + Cogswell to Schoolhouse Peak. Just before dark set about 30 oatmeal-baited Museum Specials in moist woods on north slope near cattle gap east of the five stages. Woods in Doug. fir, madrone, and tan oak, with thick duff, rotten logs, etc. Many tunnels etc. Most sets were "Blarina" sets at natural holes or holes poked into tunnels. Sat by water trough until dark but saw only one bat didn't drink. Lights of Euscevaria ble. Aug 23 Trip line in sedge seep in prairie caught 2 Sorex vagrans, 1 Mictus californicus, and 6 Peromyscus. Nothing except 1 Peromyscus out in grassy prairie. The line in woods on north slope caught 4 Peromyscus, 1 Clothronong, crossed 1 Metopus fusipes, and 1 Sorex trowbridgii. Put about 20 more museum specials in this line. The remains of the Clothronongs line at French Camp caught nothing

O. P. PEARSON 1949 9 at noon climbed big Doug fir at French camp and secured out one tree snake which Cogswell caught down below. Skinning and walking in burned woods in afternoon. Beat on many hollow trees but no results. Sight after dark and heard several woodrats, saw two bats and one deer. Aug 24 Shot one red squirrel in camp after breakfast. 25 traps for Cethrio among mossy rocks in Doug fir camp. Caught 1 more Cethrio. Also 2 Peromyscus near spring at camp. 55 traps in sedge seep in prairie and across prairie caught 3 Peromyscus, no mus. The two on north slope of Schoolhouse Peak caught only 2 more Per. Undersame [illegible] pieces of bark as yesterday's Ersatia got 2 more Ersatia and are Rhypostitutes. Certainly no water within 50 yards of this place. Woodrat specimens are being spoiled by fly eggs. The flies lay under the belly after the specimens are pinned out; then the eggs hatch into a gooey mass of larvae. Other specimens not bothered much. Set out 50 museum specula with walnuts along the road near the forks to Hoopa Valley. Mostly broken, chinquapin, madrone, and scrubby tanoaks. No bats at dusk but 3 nighthawk flew over once. Aug 25 New traps along brachy roads caught only 5 naviculatae. Old Cethrio live among mossy rocks, only 1 naviculatae. Skinning in a.m., packing etc. in afternoon in preparation for leaving French Camp for Willow Creek.

O. P. PEARSON 1949 10 A Mr MacComb, owner of the MacComb ranch near here, stopped by in jeep with a friend. MacComb, a tough hombre, introduced himself as a fish & game Coyote trapper. Days there are few left around here. He remembered Grimwell et al and said their camp (Coyote Peak) was along this road where now stands a cabin at the junction of the road over Coyote Peak, a private logging road, and this road. MacComb talked big and probably not too accurately, although he did recognizing [illegible] as a mouse that lives in nests up in fir trees. He claims there used to be more big striped skunks (not spotted skunks) here, and also grey squirrels. Days there are also flying squirrels and kangaroo rats - to which his partner agreed. Also mentioned grey fox. Says there is a small mouse not represented in our collection that eats great quantities of oat hay in the barns. MacComb is related to the Lyons (refers frequently to "Anton" [father] and "Jean" [son]) and says they settled here in 1850s. Says they settled up here rather than down below near Klondike River because of better weather, fewer rivers to ford, and less Indian trouble. Claims that the prairies are being invaded by fir and that the prairies were maintained by burning by Indians and early settlers. He remembers when the meadow here at French Camp was much larger. Early supper, then drove to south slope of Coyote Peak where road leads to cabin, spring, and a small pool (15 x 30 ft) in the forest (fir, bay, madrone, oak). Arrived about 6:20 and

O. P. PEARSON 1949 2 bats were flying already by the pool. They disappeared before I could shoot at them. They did not return in 5 minutes so I started to set out Museum Specials along a small stream through meadow with some green grass, mostly drygrass, and a few clumps of sedge. Batted with malant and sedge. Had only set about 22 when I saw bats flying, so went after them. They were feeding at edge of moade, still quite light, only two bats, quite small. Probably Mystus calf. From then until 8 p.m. numerous bats flew around the pool or actually drank. Tried shooting at first but not enough open sky to see against. Then tried netting until 8, when the numbers had diminished. at least 3 kinds present: 1) small, quiet, slow flyers that almost hovered as they drank; 2) large faster that made loud wing-flapping sounds; 3) large very fast that made wind-whistling sounds as it flew. Then jacklighted for a while. Saw and missed 1 raccoon, saw 1 Peromyscus manic, removed 2 from traps, and heard great hooted and screeched out, and I think one slave of barn owl. Then more netting at pool until 10 - but no bats. Aug 26 Some bats flying at 5 a.m. near pool but couldn't get any. Traps held 4 more mammalatus and 2 Zapus pacificus. [yesterday at 6:10 p.m., between Schoolhouse Peak & Couple Peak passed 4 gronce, 2 of them stood within 6 feet of the road as I drove past at 5 m.p.h.] In having French camp my impression is that

O. P. PEARSON 1949 12 Peromyscus manic is the most abundant and important mammal. The prairie seen to have no small mammals except mericulata, gophers, and ground squirrels*. The region is interesting in that it has Peromyscus longicaudus of the Doug fir-Redwood strip as well as Zapus pacificus. It would be interesting to know what happens to Zapus trinotatus. We have had one foggy morning here on the ridge, but the valley of Redwood Creek has been filled with fog each morning that I have seen it (at least half the mornings). * Bear fed on the numerous grasshoppers out in the prairie, and they may be jack rabbits. Left about noon for Willow Creek via Martin's Ferry, + Wetlebee + Hoopa. Klamath Valley near Hoopa is quite warm and has bigger pine. Stopping in Willow Creek, then to Salger to see Forest Ranger and talk camping sites. The store Keeper at Willow Creek had suggested Horse Ponto? or Racoon Creek, both reached by crossing the river 4 mi. north of Willow Creek (suspension bridge.) He also admitted that there were many bats in his house and in the house next door. Decided to go to Racoon Creek, 3 mi. north of Willow Creek, 700ft. Arrived 4:30 p.m. Very nice campsite along stream in maple-elder- dogwood-fir forest. Set out 55 totes (museum-special with molonto) along the stream. Great numbers of Panoxylin and solan orders (Tintums + Dicoplatodon), a few large crayfish. The woods though, whel

O. P. PEARSON 1949 the trap line runs are chiefly older + maple with a few old Dany firs. Many swordferns & madenbr, considerable more. Soil fine sandy. Bats started flying in our globs well before dusk (6:40). Shot one myoptis volans and netted 4 M. calif. before dark, aug27 Trip line yielded 9 minimilutia, 1 josep townbridgei, 1-2 proffice, and 1 minutus oregonii. Shined thru and bats in a.m. started to put out another line in pan. but saw a piggy owl being scolded by more or less tits so shot him with .22 rifle and came back to skin him. He was in brush + oak & later added about 20 more museum specials baited with oatmeal to my original line along Coon creek. The original 5-6 long or nothing during the day. Bats appeared at 6:41. Tried the concussion theory on them. First shot with .12 ga. caused one to tower upwards slowly in what seemed to be a confused fashion. He did not alight, however. Two more shots were without obvious effect. I don't think any of the bats involved were Myoptis volans. Probably Californica. Tried setting again but didn't get any. Mr. Patterson of the @ Ranch stopped in. First reach between here and Willow Creek. He didn't seem to know much about the animals around here but on his summer range in the hills above Horse Lento (± 5000-6000 ft) he talked about mountain beaver, chipmunks, bushy-tailed woodrat.

Most had bait stolen. Went to Willow Creek after lunch to look for bats. More in the nice batty attic of the Willow Creek Hotel, under the conjugated iron roof and shingles. Put out about 30 more Museum specials with wolnuts in dry scrub of oak, madrone, manzanitas, poison oak, gooseberry. Saw a few small woodrat houses and a few woodrat droppings. Went to Willow Creek after supper to hunt bats. Looked in the attic of the store-keeper's house (droppings) and under the bridge over the Trinity River (droppings). Waited by the creek under roof of hotel but no bats emerged from it. By 6:45, however, (still quite light), there were several large slow-flying bats aloft. Later there weren't least 8 of these large ones (Epleurus or bigger) and several smaller ones. Did no shooting. Aug. 29 The traps in the scrub across from the peach orchard caught 2 Zores ?strombridgii?, 4 Peromyscus truei, and 1 L. maniculatus. The old line along the stream caught 1 " and 1 each of Zores Strombridgii, S. frejus, and Meridithae. Also 1 maniculata aroundly about. Seems to have been a good night for shrews both in my line and Murray's, and I saw 2 furry forms while forestlighting last night, that I took to be shrews. Heard Chipmunks around camp for the first time,

both in the morning and late afternoons. Drove to a mine tunnel a few miles north of Hoofax one branched horizontal tunnel perhaps 300 ft deep and two almost vertical tunnels branching off from this. All fairly damp, trickle of water on floor, - but no bats or droppings. Also looked in attic of Buzard's store in Willow Creek (sic) attic for Corypholineus - but no bats) and in attic of a house near Willow Creek crossroad. All these places looked like good bat roosts - why no bats? Put out about 16 museum specimens along a trickle below steep bank along road at camp - where I saw skunks? last night. Bank mostly ferns with dense dogwood - oak - madrone forest at top of bank. Went bat shooting in Willow Creek after supper. Bats appeared while it was still light (6:50) flying too high for shooting, then gradually worked lower. At least two sizes. Murray and I got 5 of the big slow ones - Eptesicis all had disappeared by 8 p.m. Shot jack rabbits an way back to camp: One of the numerous people with whom I talked today mentioned a limestone cave south of here. Reached by driving from Willow Creek toward Saliger, where the road crosses the river turn right on the old county road and drive to Mr. Gould's place. Gould's brother-in-law (or some such) showed the entrance to the cave! While jacklighting after supper found and caught a

Went batting to Patterson reach in afternoon. Mr. Patterson told of 3 bats roosting in a rock over his bed last night. Could not find them. Set 60 Museum specials baited with walnuts + oatmeal west of the Trinity River on the flats north of the bridge. Most of the traps along a small stream bed, dry in most places, choked for the most part with blackberry willow, sedge, junco, [illegible] + water cress. Saw Meriones? droppings in several places. Blackberries ripe and abundant. One very orange Myotis calif appeared in our camp grove at 6:15. Collected him by the coruscation method. On about half of the dozen occasions when we have shot at bats under the leafy canopy of the maple grove at camp here the bat has been obviously confused and has either fled or spiralled slowly upward. True for both M. calif, and M. volans. Looked specimens for return tomorrow.

O. P. PEARSON 1949 Aug. 31 New trapline caught 5 Peromyscus, 12 song sparrow, and 3 Mueotus calif. Almost all near the ditch or stream. Nothing in the dozen or so traps out in a fallow field (Coarse grass and 1 ½ foot tall dead weed stubble). Left at 11 for home via Acreata, Eureba. Route 299 to Acreata repeats the vegetational changes noted in dropping down from French Camp to Weitelspee. Decrease of broadome etc. with increased altitude, improvement of Doug fir. Some riverine cedar as at French Camp and some large patches of prairie. There has been more lumbering, grazing, etc. along the 299 route, however. Stopped at Anita's two bat localities at Bayside and Falka and caught one or Corycorhinus at each. Also looked in a few more houses and bridges in the Eureba region but found no bats. Home 11 p.m.

O. P. PEARSON Myotis yumanensis and/or lucifugus Aug 9. Bats in large numbers flew at late dusk between spruce and bog pond and over camp. Two shot proved to be this species and most looked similar. Aug 10 Started bat hunting at dusk in meadow east of camp but only bats seen were about 5 flying rapidly towards west, none circling. Then west to spruce by log pond where many were circling. Shot 2. Aug 11 Clear dark flight and also some shining pond at 9:00 and 9:45. Shot one of these by gooklight. Aug 13 Bat flight continues to follow novel pattern - appear about 7:30 between spruce + pond, then work out over the pond at about the time it becomes too dark to shoot. Aug 14 Evening cooler than most and murkier. Bat flight less dense and their feeding more scattered. Appeared later than usual - netted one on my first sweep, none on later sweeps. Aug 16 Evening cool + clear. Few feeding by spruce but some out over bog pond. Aug 17 Disappeared the morning about 5:20 flying in remarkably straight lines without swerving, towards the forest to the east.

Aug 26 at Coyote Peak a very small bat was foraging at edge of mixed fir wood quite early (about 6:50 p.m.) In our glade 4 mi. N Wilson Creek we settled at between 6:45 and 7:15 pm. Aug 30 One very red-orange individual appeared in the maple grove of our camp at 'Covon Creek' at 6:15 p.m. Shot at him with 16 ga. half-load, whereupon he circled confusedly and landed on a branch (hanging by feet). Shot again with half-load without disturbing him. Shot again with .38 amp without disturbing him. Shocked him down by throwing rocks. He fell directly but was alive enough to bite + squeak. A half hour later another bat (probably calif. also) circled up and landed when shot at by 12 ga. full load followed by .38 amp, shot him down with another 12 ga. load but haven't been able to find him. Mayhave landed in stream. Mr. colours has done the same confused landing when shot at in the glade.

Ulquitos, however, from pine-jun grove to Sierks marsh. aug 12 Most caught so far have been immature, some probably out of the nest less than a week. aug 14 Have caught 3 around woodrat nests in last few days. aug 20 In 50 traps at French camp, 3100 ft; caught 12 overnight. At least 6 of them between 7:30 and 9:30 in the first 10 trips of the line. No really young ones. One late preg. ♀. Some were caught in pure Douglas fir, some in grass-broken, most along seep above spring. Also at holea poked into mole tunnels in Doug fir. aug 21 5 more in 50 traps. One of them quite small + grey. at 7:30 p.m. (Myotis yumanensis time) one Pero emerged from smooth round hole in bare story slope on edge of camp and ran across road. He had only ½ inch tail - probably one Gullion released from traps aug 26 Peromyscus is very abundant here in the French Camp region. Litter in all habitats to the extent of about 10-20%. catch the first night. Very few on subsequent nights. Not many really young ones. My impression is that these are paler than the Big Sur camp specimens.

PEARSON Mustelinae fuscipes Aug. 12 Set around 2 stick houses east of camp, 3 traps round one and 4 the other, caught a lactating adult and large young at one house and one of other but one trap sprung through after holding very massive. Dr. Miller says he has heard the Mustelina rattling in the bush when he interrupts search crew. Aug 13 A third one today at same nest, this one considerably smaller (and younger?) than the other two. Schuyler seems to have set off one of the Schuylers at another woodrat nest during the afternoon. Aug 14 One young one caught last night before 9 p.m., another large one seemed disturbed by the struggles of the one trapped by my foot and moved away reluctantly when I approached with flashlight, Aug 16 Jack-lighting at 8-9 along road east of camp. Heard several. After much crashing through brush I sat quietly by one nest and a woodrat came within a few feet of me about 2 minutes later. They are so innocent and guileless I don't see how they survive. Also saw one in a nest in attic of abandoned house near south shore of Big Lagoon. Aug 18 Went with Murray to 2 small clumps of small (10") redwoods with woodrat nests in them, the nests made primarily of redwood twigs, one of the nests entirely off the ground in a redwood tree. One Mustelina fuscipes caught in Schuyler in this nest and a Spilogale nearby at another nest. There seems to be a close association between these two.

Meotoma cuerea Aug. 17 Visitor to camp this morning remarked that the only animal that he noted missing from our collection was a rat about the size of Meotoma frajipes but with a tail like a chipmunk. He says he has seen them in abandoned cabins between here and Cronell. Aug. 28 Mr. Patterson, owner of ranch near Willow Creek, says he has seen these near his summer pasture which is at about 6000 ft., reached by foot trail east of Horace Sinto (20 3 miles north of here)

O. P. PEARSON Zapus trinotatus Aug 9 - Caught 5 overnight in grassy - march . Only other mammal caught there was Sorex vagrans , 3 were male, dead, and 2 females by tail, alive but cold & numb . They had not become fully active when killed about 6 hours later. More were fat, one of the females had puerperal scars plus original plug and fluid-filled uterus - hence two litters per season ? . Murray says he found a nest and litter of furred young under a board or log. Aug.10 Was surprised to catch Zapus in thick mossy spruce - fern grove. They were in or near sedge in each case. One was a non-puerperal female with thick vagina Aug.11 Dr. Miller found a young lime Zapus on the road not more than a foot from where he first saw and chased a garter snake. The snake was probably carrying it. Aug 12 More fat yet. A smaller one today had 6-mm. testes Aug 13 Caught Zapus in thick big redwood forests along stream. Aug 14 One in thick big redwoods about 100 feet above stream among ferns and bush - no sedge or grass of any sort anywhere around. Saw one in grass-thistle dry meadow while jacklighting at 9 p.m.

O. P. PEARSON Mephitis mephitis Aug. 13 One seems to have spared a prime-batted Schuyler set around a woodrat nest. When I checked the traps at 4 p.m. the smell was very strong around this trap, although no hairs in traps. Judged to be Mephitis type because there were very large skunk tracks along dusty road Aug. 14 See Philog's notes regarding above

O. P. PEARSON 1949 Subway Cave, Oct. 5 Oct. 4 Left Berkeley with autos 7:30 p.m. last night. Left south of Corning, arrived Subway Cave about 10:30 a.m. Saw no comers or Bay piles (but some droppings) at the bee place south of Old Station. No snow on passes. Found 2 Epteserus in rocks in S branch of Dubuque, but nothing else in Dubuque, Parrish, or the two Ice Caves. The temp in Parrish cave where bats were clustered last winter was 7°c (at noon). Saw a shipmark in Dubuque 75 yds from entrance, and many shipmarks around mouths of all caves. Looked in several houses north of Dubuque but no bats, then Chalk Tunnels along Pat River. Here we found a ♀ and ♂ coy in one tunnel - the ♂ topied and the ♂ awake. The ♀ had sperm in vaginal orifice, but only a little fat. Then went with Danny Shiffler to look for alleged cave across river from Power Plant. Didn't find it but he told me of another one that we located later on the river side of the water pipes where they level off after coming down the steep hill. This is a short, timbered tunnel with no bats but one large porcupine. Nearest trees were a few dogger & yellow-pines (widely scattered) and some broad-leaved trees along the river a quarter mile away.

O. P. PEARSON 1949 Then drove to Cassel for the night. Found at 7:30 p.m. about 6 Mystica brief in creamery (2 banded) and 2 Cory in the house. Both corps were fat unbanded females, no sperm in either. Why torpid at 7:30 p.m.? One more Mystica in creamery at 9:30, and one more at 5 a.m. Unfortunately, all except 2 escaped from cage overnight. Oct. 5. One more Mystica at 8 a.m. behind curtain on front door of house. The banded one that didn't escape was ♂ 49-123249. Banded also ♀ 123168 and ♂ 123169. The latter was attempting to copulate with the former on the floor of the cage, penis slightly smaller and quite red. Stopped at Duhury Cove again at 10:30 a.m. and found very tiny - supple fat female torpid in north branch. She had mated. Also another specimen in south branch. Home 6:45 p.m. via Viola + Manton. Road shorter but rough. Oct. 19 Drove Model A to Knophill, Mapa Co. Visited Knophills tunnel, 2 Red Mine tunnels, and especially the Manhattan Mine above Knophill. Found many Coryorphina (see catalog), no other lates. Dead milled and coyote hanging on fence at divide between Montrella + Mapa. Good crop of acorns can (and falling from) live oaks.

O. P. PEARSON 1949 21 Nov. 15 Left 3:15 p.m. north Anita et al. for Vallejo marshes. Set Sherman until dark along left side of Wood run and set along edge of Salicornia 2-3 miles NW of Vallejo. Purpose to catch skunks for salivary glands. I set 90 baited with walnuts (40 in grass + weeds, 50 in Salicornia and along Baccharis edge quit) and Anita 40 baited with pecans. Night cold, mostly clear. Heavy dew. By 9 p.m. Anita had 2 Zoris sinuosa, 2 Reithra, and 1 Microtina and I had 6 L. sinuosa + a complete of Mus Nov. 16 Between us 7 more sinuosa & about 7 Mus. 2 of the 15 sinuosa escaped overnight from makeshift cages. all the birds over still alive 6 p.m. Dew had frozen on one or more traps. all spotted 2 of the sinuosa came from the Salicornia or its edges. Other two from grassy-weedy line. Best sets seemed to be not quite flat Salicornia but elevated portions such as along the Baccharis edge or around a stump or log lying out in the marsh. Not much sign of Microtina. Nov. 24 Left 1:30 p.m. with Anita et al. for Grizzly Island. Put 50 Sherman baited with walnuts in low grass - weed (snortweed?) and Anita put 30. Then I put 34 Muscum Specials + 25 Sherman baited with walnuts along a choke on the edge of tule. Anita put 20 Muscum Specials here. Started catching house

D. P. PEARSON 1949 nice soon after dark. One hour after dark had 6 Mus and 1 Rattus (half-grown). Night clear + very calm. Heavy dew. Saw no Solcurns marsh. Many Ducks, Island seems to consist of a diked road around the edge of the island and cultivated fields are the edge in the center. Mon. 25 The 50 Skernans in marshy grass- weed cought 4 South crinepnes, 5 Mus, 2 Rattus, 1 Micrortus, antea 30 here had 4 Mus and 2 Rattus. Along the tules I had set alternate snags (34) and Skernans (25). Score max: snags - 11 Mus and 1 Rattus; Skernans - 3 Mus. Antea had 2 more Mus. Dec. 19 Manhattan Mines, Napa Co. Calif. Left 2 p.m. with Antea, arrived Manhattan Mines about 4:30. Went first to the tunnel to clear it. Antea, Todd + Mary had water before. Take left fork at Knopville, drive up hill to top where road forks left and large mine dump visible in to right of road. So then gate and take sharp left on dirt road.

a hundred yards or so further a large dump left rises along right side of road. Climb this to find extensive tunnel system.] In this tunnel we counted 24 Cory and 1 Epleorus, all torpid. Did not disturb them. Then drove a few-hundred yards further up road and entered another tunnel to left of road (2 Cory), then followed up to right, parked, and walked over crest to any tunnel north of the main rock dump. Found 39 bats in this one - all Cory, all torpid. Then dt. supper back at car and returned to my tunnel to sleep (7 p.m.) in view of cluster of Cory. This was the largest cluster (5) seen - almost all the rest were singles. One by one 4 of these 5 flew, as well as 2 others visible from our sleeping bag. But a few bats flying early in the evening, not many later. Can't say how much of their activity was due to our disturbance. They seemed reluctantly fly over our sleeping bag when we had a faint green light on (flashlight covered by 6 layers of green cellophane). Some made quite a fluttering sound while flying, other completely silent - perhaps depending on how fully awake they were. Dec 20 One female of original cluster of 5 Cory remained in same place. Another cluster of 4 had formed eleewhere in tunnel, and one pair [a D or look of a q, both torpid, female with large drop of fresh fluid apparent from vagina]. Collected all bats

One old male had no fat at all. How would he survive the winter ? Temperature in my tunnel (with most bats) varied during the night between 44 and 47°F. The temperature outside was as low as 26°. But coldest was the Merry-Todd tunnel which also had lots of bats. Both these tunnels were cold + drafty. Shorter & blind tunnels were warmer and had few bats.

O. P. PEARSON 1949-1950 26 had no bats this time or when Mary Todd & anita measured it. It's temperature at 10 a m was 13° C. Noted that the adult males tend to hold the tail (when folded) more tightly curled around under the body than do the females and young males. Not always, but most of the time. In each of the two good tunnels there were about nine more bats found in the morning than were counted the previous evening. It is not unlikely that some of these arrived from elsewhere during the night. In other words, bats may still be arriving at these wintering tunnels, but where are 26 of the 30 that Todd, Mary & Anita hauled a few weeks ago. at the divide between Montrello and Rapa there are now hanging on the fence five coyotes and 2 bob-cats! Fremont Peak, Monterey Co. Jan. 19 Jan. 19. Drove to top of Fremont Peak with anita, Mrs Kelley et al. looked into various natural caves and tunnels at noon. Found torpid m & f coy in small natural cave at very tops of peak. Both torpid, the female with tiny drops of blood? on tip of hairs. In large mine tunnel on south- west slope near crest we found a torpid m un., volans a torpid f ins. thypanodes, and a torpid f coy, all hanging in open from ceiling. One more f coy in a tunnel on north slope, also with blood? on fur.

1950 O. P. PEARSON 27 Feb. 11 Lubav Cave, _____ Blasta Cr, Calif. Left 7:30 a.m. for Lassen with Anita (last night). Arrived Lubav Caves 11 a.m. Clear day, 6" snow on ground. Physical conditions in the Caves was different than last year. In North branch only a few stalagnite icicles at entrance and considerable water dripping from ceiling in most places except in the long arm beyond its cave-in. The chamber where we slept last year was too wet for sleeping this year. Temp. in the bat chamber of north branch was 4.6 C. No bats present. In south branch of Lubav there were many long icicles from ceiling (none last year), some more than 6 ft long and one reaching ground from 14-foot ceiling. There were about a dozen single Cory on ceiling at drafty cross-tunnel where the ceiling temperature was 1.0 C. Body temp of one of these 9 bats was 1.2 C. In the bat-chamber the temp. was 3.5 and many Cory were present in 1 big cluster or as pairs or singles. The cluster contained 17 bats: 14 Cory, 14 S Cory, and 2 Mystria (probably M. californianus and M. subvelatus). This is the first time I have heard of any other species in contact with Cory. All or almost all in cluster had their straight; singletons had theirs curled up, or occasionally 1 up and 1 down. Read bands and bandels. Kept notes except of the 2 Mystria in the cluster (631, 632 AKP) and 3 other subvelatus hanging singly. 26 S returns, 3 female returns. Banded 3 new small spotted SS and 2 big spotted SS, also banded

Wood rat in house where we slept (on porch). at 10 p.m. found a Seeloborne between boards in a pile of lumber. Although outside temperature was not cold he seemed torpid. Brent put some nest boxes around the good Meristua marsh NE of San Rafael. I lifted a piece of draft paper in the marsh and found a Joreh and scat of straw and coarse stone—much coursier than mouse nest. The Joreh escaped. The Solvornia is becoming more prevalent, but still rather dead-looking. april 1 Left 3 p.m. with Louis Focho for Merostua in Marin Co.

P. PEARSON 1950 33 April 27 left 8 a.m. with R. Bowly + Mr. Kyford for Myotis Co. Coryphunina. Attra Spring atte had a colony of ? ?, all banded, and one young ?. also a single Myotis gurneensis barging in open from ceiling near the window. At attra Mine found 1 ? Cory in upper tunnel but nothing in others. One batte swoke at entrance to one of the 2 lower tunnels. Then drove to Knopville (one ? and ? intuned by root) and Manhattan Mines. Two ?? in OP tunnel and 2 in Catecombe. In the big open pit in a chamber across the chasm that must be jumped we found a large colony of ?? Many (severl dozen) flew when we first entered the chamber, after swinging wildly with nets for perhaps 1/2 minute we decided to let the bats settle down. Some had escaped but most quieted; whereupon we stretched nets across the entrance and caught all except a few of the remainder. Most of these were in a narrow chimney only about 1 1/2 ft. in diameter and several feet tall - a very confined space for Coryphunina. Less than half were banded ones, and many that we had banded nearly during the winter were not present (didn't arrived yet or other colony somewhere). All told there were 140 ? ? present. Banded and released all except about 15. Most of these and the Attra Spring's area were foraging. The ?? were easily divided into big + small fledged, the accessories small in both cases but smaller in the small-fledged. (young) group. Home 9 p.m.

Put up the nets and caught almost all the Cory present (about [73], all female). Not more than 6 escaped. Most quite pregnant. Only 4 were unbanded over. Opened up 6 others to measure embryo size and then sewed them up and released them. The others opened up were not preg. or resorbing, so killed them as well as 1 month broken wing. Embryo size: 49-128163 - 17.9 - 142-138157 11 x 9 mm lump 42-139189 - 16.5 - 46-26635 10 mm long " 42-138191 12.5 mm long " 49-128161 15 mm long.
