Nepalwch 1950 Journal April 23 Bill Salt and I left M.V. J. at about 12:30 headed for Bora Springs, Nevada Co., Calif. At about 6:00 A.M., near Auburn, Calif. on Hwy 40, a large mountain coyote crossed the road just ahead of the car. On the large sagebrush flat I crossed by the road from Bora to Upper Bora Springs, we got stuck at about 9:00 A.M. worked till about 1:00 P.M. unsuccessfully, trying to extricate the car. At this time we gave up temporarily and walked up to the springs. Salt shot a pair of Hudson Warblers in good spring plumage, and winged a male Cassin Finch (which he kept alive). Returned to car at about 5:00 P.M. and worked on it again while Salt prepared supper. Drove the car out to high ground just before dark. Looked for bats throughout twilight, but neither of us saw any. Bright clear, cold night. Reservoir (Kyle?) April 24 - Arose at 6:30 had breakfast; Salt left to trap finches at the spring; I re-pushed car, then walked to the reservoir looking for herpe. Found none. Saw 1 foot at close range,

Aberdeen 1950 Journal swimming on the reservoir. Numerous bluebirds seen, 2 (a pair) of Cassin Finches seen out on sage flat. Walked up to Upper Boca Springs, following the road. Near springs saw a small group of Mountain Bluebirds around old fallen snags. Junco, Audobon Warblers active in willows at spring. Returned to car at about 5:00, drove out via lower road (near reservoir). Saw shoulders on the water, & Salt shot a Brewer Sparrow on the sage flat. Spent night in tourist court at edge of Reno Nevada. April 25 - Drove back to Sacromento. Saw wren not taking dust bath at woods edge very near Boca. At about 12:30, left Sacramento & drove north through Red Bluff. Camped beside on W. side Sacramento river at jelly, Tehama Co. saw large Bigho horses (?) by Complitght, Billflogs in swish. April 26 - Looked for Salamanders out on lower river from camp. Collected one Ryla under board & 1 Bullfrog from water both at camp. Trolled

Journal 3 Kendrickson 1950 Willow-cottonwood-oak association down for about 1 mile, at which point a creek enters from W. Followed creek bed (mostly just pools in rocky bed) W. for about 1/2 mile thru dense decid-riparian growth, then back toward river staying about 100 yds. S. of creek on hillside covered with oak (very rocky). Found much "turning cover" and what appeared to be excellent Batrachoseps habitat, but no salamander. Dug gopher make out of large rotten log; its eyes were milky, and it was very sluggish. Est. length - about 4-1/2 inches. This locality is J.H. Ponce ranch (about 1 mi. N. to 4 miles S. of Bridge crossing river at Jelly). When leaving, talked with woman at ranch house who said the man say there are lots of lizards at the Bend" (this is Bend on the map, south of Jelly). Returned for Kelag 99 via Anderson (Shasta Co.), stopping once more for short, fruitless search for

Henderson 1950 Journal Batrachygea. Drove to Redding and took Hwy 299, stopping again near Shasta (Shasta Co.) and near Douglas City (Trinity Co.), collecting nothing. 2 miles beyond Helena, Trinity Co., collected one Acelyporus gracilis (?) from under dead, rotten log on oak-pine hillside. Elev 660-680 ft. elevation on Hwy 299 (U.S.C.O.G. Survey Benchmark J76, 1931: 664.001 ft.) near Salter, Six Rivers Natl. Forest, Trinity Co., Calif. In decid.-conif. forest under stones & dead wood, I collected 2 Anieles flaviguttata and adult & 1 juv. Dermborotia worlemi shastaensis. The Anieles were each under fairly solid, long, straight tree trunks, 6" & 12" in diam. at the base. The adult Dermborotia was under a rotten stump, the juvenile under a stone. Camped for night in Boise Camp, Six Rivers Natl. Forest

April 26, 1950 Collected along W. bank of Sacramento River near Jelly, Tehama (?) Co., Calif., taking Batrachyla catesbaiana from river and Hyla sp. from beneath board on sandy river bank. The area worked south about 3/4 mile from bridge across Sacramento R. at Jelly, thru oak-willow-willow association; dug gopher snake out of dead, rotten log (did not collect it)-its eyes were milky, and it was quite sluggish. About '1/2 mi. below bridge, followed by creek back from river, working thru dense decid.-uparian habitat. About 1 mile back from river (W.), headed toward river (E.) again, keeping about 100 yards S. of creek on rocky-pasture, oak-wooded hillside. There were many 'tumble' pieces of fallen wood and [illegible] rocks, and considerable oak leaf litter in spots. & This appeared to me to be ideal Batrachous habitat, and was 'suitably' moist, but no animals were found. Returned to bridge and car via river banks. When leaving a woman at the ranch house said 'the men say there are lots of 'lizards' at the bend' (meaning Bend, Calif., a few miles downriver from Jelly). Drove back to 99 via Cottonwood, then to Redding and took 299 toward the coast.

April 27, 1950 Collected in area of Boise Camp, Six Rivers Hall forest, Co., Calif. In small rocky-bedded stream running thru campground, collected Rhyaotriton olympicus under rocks resting on other rocks so that about '1/6" to '1/2" of running water passed under them. Under Rocks and fallen dead wood in vicinity, collected Ensatera. Saw a Kyra (?) in stream and collected one Rana boylii (?) from water in same stream. Left Boise Camp at about 10:00 A.M. (Lost collecting bag with field notebook there). Followed HWY to junction c 101, then drove N on 101. Stopped at Big Trees State Park, Co., Calif. & collected Batrachoseps alternatus from vicinity of Big tree under dead wood in densely shaded redwood forest with heavy bracken growth. Drove on N., camping above Coos Bay, Oregon in Eel Creek Public Campground.

April 28, 1950 Started driving at about 8:00. Left Kway 101 and took Kway 38 at Reedport. Stopped on Kway 38 about 8 mi. W. (by road) Scottsburg, Douglas Co., Ore. to collect. This point is the O.R. North farm (at present), about 4 mi. W. (by road) of covered bridge across Mill Creek. Kway at this point runs along S. bank of Umpqua River. A small canyon opens onto the road at the point where the North mail box stands. I followed this south along a dry, rocky rivulet bed and along a pipeline carrying water from about 1/4 mile up the canyon where there is surface flowing water. The canyon is densely wooded with both decid. & conif. trees, choked with fallen wood and low branches, and has a heavy layer of mosses, leaf litter, & ferns. Found Plethodon vehiculum, Anieider ferreus, and one Didelphis — under some under fallen wood, most under rocks. The canyon, and niche where I found salamanders, were quite wet. The Didelphis was under a rock in a more open hillside area. Joined Kway 99 at Drain, Ore., and followed it to Corvallis. Contacted Robt. Storm and spent night at his home.

April 29, 1950 Left Corvallis with Robt Storm and Don at about 8:30. Needed first out K-way 20 to Foster, then out road to Quartzville. Stopped first at Coal Creek, about 5 mi. E. (byroad) of Foster Bridge across Santiam R., Linn Co., Oregon. This is a rather steep-sided little canyon with slopes heavily- covered with Douglas Fir, Hemlock, and Alders. The soil is very gravelly and rocky, with heavy leaf litter and leaf mold. A heavy layer of moss covers much of the exposed surfaces, including trees, etc. Don tooks one Plethodon dunni from a loose rocky slide-face (slight seep here); Bob looks one Ensatina e. oregonae from beneath bank slab, & 2 L. dunni from beneath wood & rocks on soil. Drove on up Quartzville Road, paralleling Quartzville Creek, to Polley Mine (gold?) -- at bridge across Trout Creek where it joins Quartzville Creek. The Trout Creek is next one up canyon from Moose Creek locality mentioned in Bushop. (Moose Creek & Santiam River - should be Moose Creek & Quartzville Creek) The locality (Polley Mine) is 1/2 mile up Quartzville Creek from a Township marker which reads: Township 12 S, Range 3 E., Willamette Meridian between sections 98 & 6 (1/2 way between E. & W.) This area is heavily-grown with im-lumbered stand of Douglas Fir and Hemlock; near the (about 16.5 miles up Quartzville Rd. from Foster Bridge) (Go') (Linn Co.)

April 29, 1950 (cont.) Streams is a decid. rip. assoc. of yew, alder, & maple. The fir-hemlock stand contains many down-logs of 1'-5' diam. in all stages of decomposition. Huckleberry & salal roots are interlacing in many of the more rotten logs. Here I collected 1 Phtheochroa wrighti, Don collected 5 B. wrighti, & Bob collected 6 Ensatina e. organensis 2 Incisea forera, & 1 Plathodon sp. The B. wrighti were all collected from well-rotted Douglas fir (all?) logs, from 1" to 4" inside the logs (18" to 3' diam.) in footwormpin chambers or cracks. Water could be squeezed from the surrounding wood. The wood temp. where the animals were was 6° C, The air temp. was from about 12° C. to 14° C. Left in late afternoon & drove back to Foster Bridge; there I collected 4 small Pana boylii, several Incisea forera, and 2 Eumeces skiltonianus. From Foster Bridge across Fountain R. drove via Berlin, Scio, Shelburn, Stayton, Sublimity & Hwy 214 to Silver Creek Falls State Park. Custodian allowed us to camp there for the night (not usually permitted). Heard type in a nearby beaver pond.

April 30, 1950 Examined low-beaver James O. Beaver's work near camp. Several 2"-3" diam. Douglas firs cut down and some bark stripped from each. While standing on bit of "higher ground" in swampy area of pond, substrate gave way & I dropped to my waist, apparently having caved in the top of a house or burrow. Left park & on 214 via Silverton, that 211 via Molalla, Colton & Estacada via 50 then 50 to what was decided must be type locality of B. wrightii: 8.5 miles (by road) E.S.E. of intersection of highways 211 & 50 in Sandy, Clackamas Co., Ore. This is near Baldor Creek at about 1300 ft. on the topsheet. Highways 211 & 50 intersect at the N. edge of the town of Sandy, about midway between E. & W. limits. If one assumes that Bishop drove from Portland out Highway 50 toward Mount Hood, and that the city limit sign he saw as he approached Sandy from the west was his point of speedometer reading, then this approx. equals his "8.7 miles S.E. Sandy on Mt. Hood Highway". The locality is about 1.3 miles beyond Cherryville, on the S. side (N. slope) of the highway. The slope is lumbered somewhat, most near the road. The trees are mostly Douglas firs and Hemlocks in the estimated proportion of 3:1. Salal

Vandnickson 1950 Journal June 8 Guadalajara to San Marcos, Jalisco Most of the way over small, very rough road. Collected one small lizard by roadside, E. of Ahualulco. Speedometer reading = 74.1. Etzatlán = 91.4. / San Marcos = 99.8. In roadside puddle 0.7 mile farther on collected a number of metamorphosing tadpoles (Scaphiopus ?). Water muddy, and quite warm (about 38-40° C.?) June 19 San Marcos, Jalisco, Mexico Collected one toad (#1062) from well (water level about 20 ft. down) in town of San Marcos, two more from under large stone in arroyo at edge of town. Collected Cremidophorus (?) & Seelognus (?) with slingshot from arroyo and on stone fences at edge of town.

Lundricken 1950 Journal June 20 Went with three de Aguiro boys and a neighbor boy (in my car) to mountains west of San Marcos (Sierra de Jitlan). About 1/3 of way, at ranch settlement called Puerto de Cocker, collected Gymnidophorum and Scelopus with slingshot. Went on over about 10 miles of exceedingly rough, washed-out road to Rancho El Rodeo, another ranch settlement and charcoal depot well up in the mountains. Major tree cover at El Rodeo is Quercus macrophylla, a very large-leaved oak growing about 20-35 ft. high as seen here. Pines (?) or other conifers were visible at higher altitudes, but were not reached. The country is much-worked by charcoal burners and no extensive dense plant cover exists anywhere we visited. Water was standing or flowing at many points in arroyo bottoms, but high ground seemed quite dry. Collected two Bufo and two Hyla arenicolor (?) from burrows exposed by rolling large boulders (5 to a team, rolling 3' x 5

Nordickson 1950 Azural June 20 (cont.) Bufo & Kyla were about 1/2 mile from nearest observed [illegible] surface water at this time. Near arroyo bottom, in 12" x 48" stagnant pool filled w green algae, took number of small Rana, imm. T. hamnohric, and baby turtle. In running stream its arroyo bottom toole more Rana, and along margins toole a few lizards. In rockpile near stream took Trimorphodon (found well down in pile). Two light showers occured during day. When returning to car at about 5:00 (just after second shower), took Kyla aronicolor sitting exposed on top of rock in bottom of small arroyo (1 pool of stagnant water about 100 ft. or down arroyo was only nearby water noted). Returning to Puerto de Cochon, collected two large Bufo from under large boulder in arroyo bottom (these were later lost). About 1/2 mile from Puerto de Cochon (rd. to San Marcos), collected 1 Rana from muddy roadside pool. On returning, found that one of the smaller de Aquino boys had brought home a racer which had been killed in town during the day.

Hendrickson 1950 June 20 (cont.) Journal Derrhontes Buzz. Note on Dera & Craxidophorus "voices" Dana were heard calling at two diff. localities. The second time, when the calls were heard for an extended period, one was traced to an area of about 2 ft. diam. without sighting the exact source of the calls. Intensive search (visual) followed by rock-turning revealed one small Dana and no other amphib. The local boys who were with me identified the calls when first heard as those of this frog. They apparently knew it well. The sound is a subtle, but penetrating tol... tol... tol... tol... which reminded me very much of the sound of spiced drope falling from a leaky faucet into a container I estimated the frequency of the calls at roughly 21/2/sec. / Three times during the day Derrhontes were seized in the hand unhurt or only slightly

Hendrickson 1950 Journal June 20 (cont.) injured by the slingshot. Twice that night during preparation of specimens, active animals were similarly seized (for killing). In each of these five instances mentioned (other similar instances not counted), the animals, with mouth opened wide in defensive attitude, emitted one or more loud, still fairly mouse-like squeaks.

Hendrickson 1950 Journal Marsh Creek, 4 mi. E. Mt. Diablo, Contra Costa Co., Calif. Aug. 14, 1950 Took the family to this locality for a picnic and search for Reticulitermes (food for Batrachophaga). The lunch beside a fairly large pool in the otherwise dry creek bed. This pool was just below a large, gravelled shoulder on the road as it sweeps S.E. - E. around a bend in the canyon. The pool measured about 18' x 60'. (Clear, with stony-muddy bottom and some fil. algae). A search for lemmite proved unsuccessful and I returned to the pool to play with the children. Collected two Pana aurora and eight Pana boylii boylii from the pool, as well as two metamorphosing aurora (?) tadpoles and a small minnow (Agosia?). There were many adult frogs and large numbers of newly metamorphosed frogs concentrated in and near the water. Saw two Hyla regilla of this year in the pool, also.

Journal Hendrickson 1950 Marsh Creek (cont.) (Aug. 14, 1950) Approx. 20" [illegible] taken near pool. Saw a number of adult Sceloporus, mostly on tree trunks, and noted fairly numerous tiny Sceloporus. Those looked newly-hatched; they were seen, for the most part, in dry grass and around dead wood and stones near the creek bed.

Hendrickson 1958 Journal Los Angeles to Lower Covington Flats, 5000 ft Riverside Co., Calif. Aug. 22 Left Loye Miller's home at about 8:30 A.M. and headed for 29 Palms. About 4 miles E. of the W. city limits of 29 Palms, Dr. Miller spotted a young coyote, badly macked and dried, beside the road (Morongo Valley - 29 Palms Road). About 5.8 miles E. of the W. city limits of 29 Palms (on same road as above), Dr. Miller pointed out the Indian Cove, where he collected Kylea aronicolor previously. A road junction, with Indian Cove labelled, is located about 3 miles E. of 29 Palms. A much-broken, granite ridge runs almost parallel to the road, about a mile (or more) d. of the road. Indian Cove is located at about the point where this very rough ridge joins a somewhat-higher ridge which is more soil-covered and much less broken-up. This latter ridge also runs parallel to the road.

Hendrickson 1950 Journal Aug. 22 Los Angeles to Lower Covington Plate, 5000 ft., Riverside Co., Calif. After lunch in 29 Palms, gassed cars and visited Joshua Tree Natl. Monument Headquarters. Obtained information and maps from Custodian (Obtained several of the small information folders containing small maps of the monument). Drove W. on 29 Palms- Morongo Valley Road, turning off about 3 mi. W. of the town of Joshua Tree. Joshua Tree is dominant on this road near the 29 Palms-Morongo Valley Rd., with "Burron Brush" and a few Creoste Bushes. The road, heading approx. south at first, climbs slowly but steadily toward a series of steeper, rocky hills. Near the hills Yucca mohavensis becomes fairly common. A sparrow hawk was seen at about this point. Oquntia bigelowii also seemed more common near the hills. The road rounds a granite spur and flatter ground, entering a broad notch in the range of steeper hills. On this flatter terrain Junipers and Joshua Trees are dominant. Jerry Russell saw what was probably a Road Runner here. Took the left branch at a fork and again began a gentle climb. Helvia became common on the hillside, along with Junipers, Joshuas Trees, and Yucca mohavensis. Divyon makes its appearance near 5000 ft. Passed an old mine up on the hillside and began to drop into Lower Covington Plate. This appears to be more or less of a

It soon enters a rather narrow, steep-walled canyon below the windmill which marks Corvinton Well (dry). Desert Willow and juniper in the wash, Pinyon tree and Joshua Tree (widely scattered) seeds on the slopes are the dominant plants noted. Made Camp about 500 yds up the wash from Corvinton Well. Camp roughly established by about 5 P.M. Walked, with Bailey & Harry Russell, down the wash to the point where it enters the steep-walled canyon, returning to camp for supper at 6:00 P.M. Saw Morning Dove, Empeionex (?) and saw one Dolphin-cher (?), as well as about 7 Utras. Collected one small immature Utra stansburiana and one adult. Saw but missed, one Kentuckia vigilis under bark of a dead, fallen Joshua Tree; it ran into a hole in the base of an adjacent, living Joshua Tree. After supper saw several bats, probably Myotis (?)

Took Dustcatcher from bushes in bottom of wash. Saw jackrabbit here. About 1/2 mile up wash, turned E. up wash and started climbing toward ridge E. of Covington Plate. Took Bush-tit from scrub-oaks in this wash. While investigating fairly large hole dug under large rocks: (badger!) a large bighorn sheep ran started up about 100 yds. distant on opposite wall of canyon. Ran almost leisurely along opposite slope and across canyon ahead of me, tumbling several sizable rocks as it went. The coat seemed rather ragged. The canyon at this time was still shaded from the sun. Took Kertia under Joshua Tree log in small bowl forming head of this canyon, still below the main ridge. Kantusa temp. - 19.2° C. soil temp under log- 18.5° C. air temp at o" lat. - 18.0° C.

The rock on which the snake rested was under a N-facing overhang of a large boulder: [illegible] The snake was not in a "dish-mat" coil, but was in a zig-zag coil: [illegible] Its head was resting on the rock and it made no move until moved. 8:00 P.M. temp.-23.3°C.

Hendrickson 1950 Journal Aug. 24 Lower Corington Plate, 5000 ft., Riverside Co., Calif. Corington Well is a small, concreted dam and (dry) below the dam seepage accumulates to about a quart or two of water. Mountain Devil (5) flushed from this water hole as I approached. About 3/4 mi. below this site, another water hole hold perhaps 1 1/2 gal. of water. Near this site cottonwoods and true willows were growing along with mesquite, catclaw, and juniper. About 25-50 yds. above this water hole, in a small thicket of 10-15 ft. cotton- woods, I found the skull and vertebral column of a Bighorn Sheep (shell is #1213 in my catalogue). Near the water I took a Pileated wambler from bushes in the wash bottom. While putting the bird in a cone, a young Bighorn sheep started up about 75 yds. away on the opposite wall of the canyon. I walked to a large boulder & stood on it, watching me, for about 30 seconds, then walked up to the ridge above and stopped again to look at me before going down the other side. I realized this animal had about 60° of curl to its horns.

Hardrickson 1950 Journal Aug. 24 Lower Covington Flat, 5000 ft., Riverside Co., Calif. I walked on down the canyon to a point where it was definitely beginning to widen out into a wash on the lower slope of the mountain. At this point I encountered car tracks in the sandy bottom of the wash, the vehicle having entered from below. A short distance from or down from the point where I first encountered the car tracks, the canyon turns from a N.N.E. direction to an E.N.E. one. At this point I started back. Considerable Catclaw occurs in this lower part of the canyon. Near the end of the car tracks I found a strip of white cloth tied to a catclaw branch, like a trap flag. I could not locate a trap or any other deposited object near it. At 8:45 returned to Lower water hole (dam), and took a Calif. Jay from a group which had been bathing in the water. The water was piled; and the bird I shot was quite wet on breast and wings. There is considerable growth of mosquito in this vicinity. Returned to camp, then went out to check steel traps set

Verdrickson 1950 Journal Aug 24 Lower Covington Flat, 5000 ft., Riverside, Calif. in wash behind (S.) camp. Traps were undisturbed. At 10:30 A.M. took Sceloporus occidentalis in this wash. Cloacal temp. = 37.1; shade temp. where shot = 31.8. Returned to camp and prepared specimens till about 4:00 P.M., then went out with Ward to place rabbit bait near steel traps. Returned and worked on snake trap until suppertime. Aug. 25 Started out at 6:00 A.M. to search tunnel wash in 2nd canyon S. of camp for lizards and bats. Found none. Worked into 1st canyon S. of camp and walked up it toward Upper Covington Flat. At 7:45 shot Cnemidophorus; cloacal temp. = 40.5°C., soil substrate = 33°C. At 7:50 shot Sceloporus magister; cloacal temp. = 32°C., rock = 29.2°C. At 8:10 shot Sceloporus occidentalis; cloacal temp. = 31.0; rock (shade) = 27.4°C., rock in sun = 37.5°C. At 8:12 shot Cnemid- ophorus; cloacal temp. = 39.8°C., leaf litter = 43.6°C. At 9:00 climbed canyon through area where it crosses bed rock granite, with water-warm slides. * Covington Springs

Nerdrickson 1950 Journal Aug. 25 Lower Covington Plate, 5000 ft., Riverside Co., Calif. and pot hole filled with sand. In one of the larger of these pot-holes was a pit dug by coyotes (?) for water. The sand in the bottom was wet. This hole was cone-shaped due to cave-ins during the digging. It measured 12' 2" in diam. across the top of the cone, and was 3' 4" deep. The bottom was about 8" in diam. Took Rock Squirrel and Chipmunk in vicinity of the water hole. There were many honeybees on the camp sand and in the bottom of the hole. About 200 yds. uphill from camp took Erostaphytus collarie on N.E.-facing slope with many large rocks on sandy-gravelly soil. The vegetation was piyon-juniper. Returned to camp & prepared skins until about 5:00 P.M. Aug. 26 Left camp at 6:00 A.M. (temp. 15.7° C.) Went up first wash S. of camp, found young mole coyote in trap & returned him to camp with Bailey's aid. Set out again for second steel trap; found it unsprung, but half rabbit used as bait was gone.

With a shovel I deepened the bottom a few inches and removed a great deal of sliding sand to create a much broader crater with about a gallon of water in the bottom. Watched from vantage point near hole for some time, then set steel trap at edge of crater and left. Returned to camp and prepared specimens much of remainder of day. Checked snake trap upon return to camp; found one Sceloporus occidentalis and one Uta stansburiana in trap. At about 3:30 P.M., checked trap again found another Uta; went on and checked *tunnel in second wash S. of camp*. Found no bats. Temp. at 8:30 P.M. = 20.6°C in camp, tunnel at 9:00 P.M. = 23°C, Aug. 27 Temp. at 4:45 A.M. = 13.4°C.; at 5:45 A.M. = 15.6°C. Left camp at 5:30 A.M.

Hendrickson 1950 Journal Aug. 27 Upper Covington Flat, Riverside Co., Calif. 6:30 A.M. = 24.0°C. Upper Covington Flat is a N.-S.-elongate bowl with a fairly gentle W. slope (up to a steeper W. rim where the last 100 ft. ↑ of rise is fairly steep) and a more steep and rugged E. slope. The drainage of the flat falls fairly near the E. slope. The entire bowl appears to drain through a notch in the E. side near the S. end, and the canyon starting here is the one which becomes the first ½ wash S. of camp. The vegetation of the flat itself appears to be primarily Joshua tree-juniper-bunch grass. About 10 yds. down the W. slope of the ridge separating Upper from Lower Covington Flat, found 3 Rock Squirrel (?) holes which had apparently been extensively excavated by a badger. Out on the Upper Flat I saw several other similar areas of what appeared to be badger workings. Fresh gopher workings were also fairly common - although widely-scattered - on the Upper Flat. & Twice I saw what might have been Digo tracks in areas of fine sand.

Hendrickson 1950 Journal Aug. 27 Upper Covington Flat, Riverside Co., Calif. In about the center of the Upper Flat I saw what definitely was a bluebird (closer ident. not practicable), and shot at it, hurting but not stopping it. The distance was considerable, but it may have been a female Mexican Bluebird. At 7:40 A.M. reached W. rim of Upper Covington Fl. flat; off the W. rim the terrain drops off rather rapidly in hilly country descending to the Coachella Valley. Pipistrelles were flying on the W. side of the rim (largely still in shade). At 8:00 A.M. the shade temp. on the W. rim was 29.2°; a Cnemidophorus taken at this time had a cloacal temp. of 38.4°c., the sunny soil on which it was sitting was 40.1°c. Saw more gopher mounds and badger workings upon returning across Upper Covington Flat by a different route. The bunch grass on the flat is in clumps 8"-12" high, about 3'-4' apart. Followed drainage out of the flat and down canyon mentioned earlier. Willow were found in the canyon bottom near its origin from the flat.

Kendrickson 1950 Journal Aug. 27 Lower Corvinton Flat, 5000 ft. Riverside Co., Calif. At 8:45 took Cnemidophorus from beneath desert willow in bottom of upper canyon. Cnemidophorus = 40.5°c.; dappled shade where taken = 34.6°c. (leaf litter-gravel). Returned to camp and prepared specimens. In afternoon went to tunnel at Corvinton Springs (with Jerry Russell), took Hylotis thysodes (see sp. acc.), and set two rat traps (Mustela (?) droppings in tunnel). Aug. 28 Left camp at 5:15 A.M., temp.=16.4°c. At 5:20 A.M. in 1st wash S. of camp, temp.= 15.9°c. Went to tunnel at Corvinton Springs; found no bats. Temp. 35 ft. back in tunnel at 5:25 A.M. near ceiling = 20.2°c. Returned to 1st wash S. of camp, checked steel traps (nothing), and cleaned out some of sand in water hole. 7 Mountain Javal left as I approached water hole; killed one which was in fairly good plumage. Took Empidox, Distatcher, and Calif. Jay near water hole, then remained quiet at observation post for about 2 hours. Calif.

The chipmunks reacted only to sounds and the most gross movements (I was about 35 yards from the water, up on the canyon wall). The quail seemed little or not at all disturbed by my movements and the sounds I made in moving. It repeatedly approached the pit and started down the steep slope (it seemed reluctant to use the more gradual slope which I had created), stopping about 1/3 of the way down when dislodged gravel rattled into the water), crowing its neck and bobbing its head. Each time it then retreated back to the level without going on down, returned to the shade for a few minutes, only to return, circle the pit partially or completely and repeat the performance. Obviously (!?), thirsty, it never did get any water while I watched it. At 10:20 A.M., the crack from which I took a Pipistrelle showed a temp. of 30.5 C. The sun was just beginning to fully light the face of the rock on which the crack opened. Upon removing water from the water hole

Hendrickson 1950 Journal Aug. 28 Lower Corvinton Flat, 5000 ft., Riverside Co., Calif. (about 3 gal.), I observed that the coarse gravel in which the water is contained allows a rapid flow into the depression. The 3 gal. were removed in about 10 min. time, and the level did not recede noticeably. On cleaning out caved-in sand, if a double handful of sand is removed near the water line, the depression left is filled with water when the next double handful is taken out (a few seconds later). At about 8:30 P.M. checked tunnel at Corvinton Springs - no bats, traps undisturbed. - At about 10:30 A.M. today, at my water hole, saw what I am almost certain was a Red-Breasted Nuthatch. Aug. 29 Temp at 6:00 A.M. on ridge about 25 ft. above wash bottom = 16.8°C.

Hendrickson 1950 Journal Aug. 29 Lower Covington Flat, 5000ft., Riverside Co., Calif. preparatory to breaking camp. Arrived at waterhole at 6:30 A.M. - no Pipistrelle flying. At 6:50 A.M. first Pipistrelle noted flying. Sceloporus magister seen descending steep slope of water hole; remained (unseen) in bottom for about 10 min., then ascended the gentle slope and continued on to other side of canyon. A Calif. Jay came to the water hole at about 7:30 A.M.; as I watched closely, it hopped into the bottom of the hole and apparently thrust its bill into the damp sand for water. Cave-ins of sand during the night had filled in the open water, leaving only damp sand in the bottom of the hole. The water level was about 1/4" - 3/4" below the lowest sand surface. The jay did not scratch to remove sand to the water level, and did not "dig" with its bill. It actually seemed to "drill" its bill into the sand, coming up to a "look-out" posture, then repeating the process. At 8:45 A.M., Returned to camp at about 9:00 prepared specimens. Broke camp at about noon, drove to Joshua Tree for car service and groceries, then went to:

Hendrickson 1950 Journal Aug. 29 Black Rock Spring, 4500 ft., San Bernardino Co., Calif. Made camp by about 3:00 p. M., about '¼ mile above the spring. A small amount of water is in the spring, although a nearby concrete watering trough is dry. A 55 gal. drum supplying a sardine tin (?) as a "guzzler" also had water. This is located about 200 yds. up the canyon from the spring. The canyon is a fairly narrow one from the spring on up past our camp, with some fairly rocky areas in a sand-gravel hilly slope of the mountains. The canyon bottom and bottom of many of the side canyons are sandy. A number of mosquitoes grow in the canyon bottom and on the low slopes in the vicinity of the spring, and a few milfoeeds (?) were noted in the sandy area near the spring. The spring consists of a rock-lined depression beside the road (in the canyon bottom) at the end of a minor ridge ending between the main canyon and a side canyon. I set a steel trap by the spring. Jerry Russell, hunting late up-canyon from camp, collected a small Crotalus mitchelli this evening. Aug. 30 Hunted, with Jerry Russell, near the spring until about 9:00 A. M. Many Caly.

We collected 5 out of perhaps 50 in the neighborhood during the time we were there. Collected Calif. Woodpecker which lit on Joshua tree in canyon bottom about 75 yds up from the spring. Returned to camp and skinned until 3:30 P.M., then went with Jerry Russell (in truck) to: 3 miles S. Warren's Well, 3750 ft., San Bernardino Co., Calif. We set out 97 large museum specials on a gentle slope (yucca-cholla-Joshua tree-sage) of gravelly soil. Investigated vacant house near this area and found what seemed to be bat sign; plan to return at a later date to look for bats. Black Rock Spring, 4500 ft., San Bernardino Co., Calif. Set steel trap in sandy side-canyon about 1/8 mi. N. of camp; baited with 2-day-old mountain quail. Set 2 rat traps near woodrat house, and 2 gopher traps near camp, set up snake trap across small wash just N. of camp. Aug. 31 Set out with Dr. Miller & Jerry Russell (in truck).

Saw a large bat (est. 12" + wing span), and took 2 Poorville on the road. Several large, active-looking Woodrat nests near in mesquite near spring. Sept. 1 50 Museum Specials set last night from vicinity of spring in line running roughly N.-S. about 50 yds. W. of road. Took 5 Perognathus fallex and one (im.) Peromyscus crinitus. Bob Norris set 50 traps (in similar orientation to road?) S. of camp in higher country; he took one Dipodomys merriami, 1 Perognathus longimembris, and 1 Peromyscus truei. Jerry Russell and I hunted toward and around the spring in the A.M. The steel trap set at the road fork (quail bait) had been dug out of spring, and the bait stolen. Apparently an experienced coyote was responsible. Left the area untouched; Ward Russell will set a larger trap nearby, using the exposed trap plus scent, as an attraction. At the spring we flushed another deer - a doe. The steel trap at the spring had been.

Bailey and Russell went on in the truck to Joshua Tree for supplies. Miller, Jerry Russell, and I remained near the spring. Miller hunted Poor-Willis and Owls while Jerry Russell and I set up the nylon hair net for bats. Toole & Pipistrelles with the aid of the net. The bats were clearly able to detect the presence of even this very fine net, although the occasional ones which hit it indicated that this obstruction might be near their limits of perception. The net was stretched tightly in vertical position from the rocks above the spring out into the road. Its area was about 4' x 8'. I knelt at one side of it, attempting to place a hand over bats contacting the net. Many wheeled close about my head, and twice contacted the net in the act of circling my head. Many times bats approached very close to the net,

Only quail, jaya, and warblers visited the water. The traps at the woodrat nests were empty. I left the spring and followed a much-used deer trail eastward around the main N.-facing slope of the mountain into the next major wash, then worked up the wash (5.) and circled back to the road following the ridge most of the way. On the main N. slope took a Deeloporus from a Joshua Tree (about 8' from ground): cloacal temp. = 36.3° C., shade temp. = 38.5° C.

Flushed a Poor-Will (?) from rocky area near fork in road between the spring and camp. An exhausted Rufous Hummingbird came into the tent and I netted it with a bat net. Prepared specimen most of day. At about 8:00 P.M. it began to rain, and eventually it haild. I estimate about "1/2" of precipitation (I believe there may estimate more). A small flash flood came through camp; at one time the water was ankle deep in the tent. At 9:30 P.M., after the main precipitation, the temp. was 15.2° C. 6" above the ground. Sept. 3 Jerry Russell and I walked up the canyon to the end of the road, then to the highest adjacent "peak" E. of the saddle where the road ends.

Returned down road about halfway to camp, when I found a tiny Chrynosoma coronatum. Zigzagged across wash most of the remainder of the way and collected 3 more (see species account). Collected Foguli Bunting from Manzanita bushes about 1/8 mi. S. of camp. In afternoon Jerry Russell returned from the spring and said he thought he heard a toad croak a few times from the vicinity of the concrete trough. After supper went to the spring with Ward and Jerry Russell. Many bats, apparently almost all Pipistrelles, were flying. A party of weekend picnickers was at the spring.

The men went into the brush and I believe they picked up their guns which had been hidden. I walked about 1 mi. down the road from the spring and returned, using a headlight all the way. No corpses were seen. I only saw one eyeshine -- presumably an owl. The concrete trough below the trough held about 6" of water in one section, 1"-2" in the other. 100 Museum Speciales were set along the side of the road between camp and the "guzzler". Sept. 4 100 Museum Speciales contained 1 Dipodomyx morrisoni and 1 Perognathus fallax. Rat traps were empty.

At about 11:00 A.M., walked to Stubby Spring, 4500 ft. The water emerges from an E-facing slope as a seep. It is collected in a small (18" x 36") concrete trough at the bottom of the seep, and in a large (18' diam.) masonry tank about 40 ft. down canyon from the above trough. The tank is about 4' deep; at the base of the down-canyon side of the tank are two low concrete troughs filled by overflow from the tanks. At this time the pipe carrying water to the tank has an estimated flow of about 2 gts./min. The canyon bottom around the trough has a rather dense growth of Chrysothamnus. Below the tank is an area about 200 sq. ft. of sedge (?) and stubble about 2" high. Above the seep, on the hillside is a single large willow, with several smaller shrubby trees. Above this, or a somewhat more gentle slope than much of the rest of the hillside, is another area of Chryso- thamnus. I picked a nearly complete bat skeleton (really a rain-wetted mummy)

Sept. 7 Set 4 steel traps on boulder hills just N. of camp, then worked S. to trail leading to Stubby Spring and followed it to point where it crosses first canyon E. of the spring. Followed this down to its junction with the canyon draining the spring. The morning was overcast until about 8:00 A.M. The rain of the preceding day had soaked everything, and the soil was muddy in spots. Termites were flying in numbers, and birds and lizards were actively feeding on them. The canyon I followed is rocky and rather narrow, with a sandy bottom over much of its length. Many Sceloporus occidentalis were feeding out on the open, flat sandy areas. At one point I observed 7 individuals foraging actively on the canyon bottom ahead of me. The sandy area was from 10' to 20' wide at this point, and the 7 animals were strung out over about 75 yards of canyon bottom. Rarely did they come into close proximity with each other, but there seemed a

One animal collected had a temperature of 25.2°C.; the sand on which it was shot was 20.0°C. (overcast at the moment). Went up to vicinity of spring and worked intensively over the area of the tank, seep willow tree, and ridged exposed rock just above the tank. Found 1 Crotalus mitchelli, 1 small Bufo punctatus, and 1 sheep jaw on the exposed rock just above the tank; nothing more. Under the large willow is a sort of bowl about 10 ft. in diam. containing a thick litter of leaves, rotted limbs, etc. Looks ideal for skinks and amphibs., but intensive search revealed none. The big tank and its low troughs contain tadpoles; on one of the larger metamorphosing tails, I noted the characteristic red punctate markings of Bufo punctatus. Many dragon- fly larvae were seen in this water also; one was eating a tadpole. About 25 yards below the large tank collected a Crotalus mitchelli (see species account).

Fresh deer (?) trails were encountered twice in the wash. Collected a Verdin, a Ladderback Woodpecker, a Western (?) Flycatcher, and a Warbling Virginia Warbler while hunting in the wash. Returned to truck, met Dr. Miller, and drove to a point about 10 mi. S.E. Joshua Tree P.O., San Bernardino Co., Calif. Here we hunted near the road (to Joshua Tree) for about 1 hr. Collected lg. Sceloporus magister from bare sand-gravel on gentle W-facing slope. Dominant vegetation was Creosote-Joshua Tree-Cholla-Ephedra. Temp. of animal was 35.0 C.; air temp. at 6" was 32.4 C.; substrate was 38.2°. In area of large granitic boulders above road, caught a fleeting glimpse of a fox.

Hendrickson 1950 Journal Sept. 8 3 mi. S.E. Joshua Tree P.O., San Bernardino Co., Calif. Drove up side road off H'way (to Joshua Tree) to the same ly. wash which runs below Quail Spring. Collected three Callisaurus (see species account). Drove to Joshua Tree for groceries and tire repair, then returned to camp at Stubby Springs. On the return trip to camp, saw three Golden Eagles (ident. A.H.Miller) soaring rather low. This was about 4 mi. S.E. Joshua Tree P.O. Sept. 9 Stubby Spring, 4500 ft., Riverside Co., Calif. Looked at steel traps on hill N of camp; two had been disturbed, apparently by rodents. Walked W. from hill, eventually dropping into large canyon which forms from canyon in which spring is found. This becomes a rocky gorge of about 300' - 400' depth, and is very rough. Air temp. at 5:00 A.M. was 10.6° C. The day was clear and cloudless and soon became warm. Collected a new-bom (?) Xantusia from under banks on dead Joshua Tree log. Climbed wall of gorge and worked S., coming onto Stubby Spring from the W. Collected Scrub-Jay,

Dwail spring, 3700 ft., San Bernardino Co., Calif. Polt. Bailey, Polt. Norris, Jerry Russell and I drove to the tanks at about 6:00 P.M. Set up fine hair net for bats. Set it vertically at first; 3 Pipistrelles were captured. Then set it horizontally; 1 Myotis (volans?) was caught. Larger bats were seen flying. The Myotis was much entangled, and tore the net somewhat. Sept. 10 Returned with Bailey and Norris. I stayed near the spring tank. One Myotis (volans?) - dead - and one living Eptesicus were entangled in the net. Collected Lawrence Dollfinch, Aransas Dolfinch, and two House Finches. Drove to Joshua Tree for A.M. & Mrs. W.D. Robinson drove up while I was at the spring. They reside at Valley View Circle, Joshua Tree Natl. Monument. They claim interest in the local bird life and several observations by them follow (as given to me in their words):

These men told of "black squirrels", larger than Chipmunks, which they commonly saw around the Hidden Valley Picnic Grounds. About 5:00 P.M. we investigated the area, in their company. We saw no squirrels. Sept. 12 Stubley Spring to Cottonwood Springs, via Ivanpah Tank, 29 Palms, and White Tanks, Riverside San Bernardino Co. Bailey, Norris, and Jerry Russell left for Berkeley at about 5:30 A.M. Dr. Miller, Ward Russell, & I broke camp at about 9:30 A.M. and drove to Ivanpah Tank, 4200 ft., Riverside Co., Calif. This is a damned basin in rotten granitic rock. At the present time it is almost filled with muddy water -- apparently a result of the recent rains. This appears to be only temporary water; there is a trickle below the dam, which contains where some filamentous green algae indicates at least semi-permanence. There seemed to be no specialized vegetation associated with the tanks other than the above-mentioned algae. I took a Callisaurus draconoides from granite gravel, among the decaying granite boulders, at the edge of the tank. Leaving Ivanpah Tank, we drove to 29 Palms, 2000 ft., San Bernardino Co., Calif., where we bought supplies. On Adams Road, a few blocks of Monument Headquarters, we saw a Dipso...

Visited Monument Housequarters and spent about an hour in conversation there. One of the men reports a Heloderma seen wandering down a road in 29 Palms "quite a few years ago"; this was presumably an escaped animal. Enroute to Cottonwood Springs, stopped at White Tanks, 3750 ft., Riverside Co., Calif. This is another picnic area of huge granite boulders and coarse granite gravel. Just after leaving the car, upon crossing the picnic area, Dr. Miller found a small (this year's?) Bytho punctatus (see species account). I wandered along a small wash running among and under large boulders of the picnic area until I came upon one of the tanks. A small concrete dam had created two pools of run-off water (each about 10' x 20'). These pools were fairly well shaded by boulders, and had a semi-permanent appearance. There were patches of rank grass about the margins, and dead stems of rushes in the water of one of the pools. One contained myriads of Eubranchippus (?) and many Gnus (?). A killdeer flushed from this pool as I approached. Collected several tiny Bytho from mud at margins of the pools. Below the dam was a series of small pools,

Kardrickson 1958 Journal Sept. 12 White Tanks, 3750 ft., Riverside Co., Calif. most of which appeared semi-permanent. Collected Tadpoles here. No signs of Kyle, although it appeared to be a possible habitat for them. Drove on to Cottonwood Springs, via Pinto Basin. Entering Pinto Basin from the N.W. (from 29 Palms), we passed thru a lg. patch (belt?) of Opuntia Bigelovii; the road passed through this type of vegetation for about 0.7 mile. This followed by Ocotillo, through which the road passes for about 1.2 mi. Cycladrea and Croosote Bush are also dominant further toward in the Ocotillo zone. At the bottom of the basin, Smoke Trees are strung out along this a wash running approximately N.E.-S.W. (?). The speedometer distance from the upper edge of the Opuntia Bigelovii to the wash is 3.2 miles. The distance from the wash to the turnoff to Cottonwood Springs is about 22.3 miles. We made camp at Cottonwood Springs, 3040 ft., Riverside Co., Calif. At about 4:30-5:00 P.M. 4 Gray Frogs came out to a feeding tray about 20 ft. from our picnic table (see species account).

Kerndron 1950 Journal Sept. 13 | mi. W. 2 mi. S. Pinto Mts., 1750 ft., Riverside Co., Calif. Dr. Miller and I drove to a point near the large sand dune in Pinto Basin. This is situated on the N. side of the basin, about 1 mi. from the road at its nearest point. Arrived at top of dune at about 6:40 A.M. The temp. 6" above the sand at that time was 19.6°C.; the temp. of the surface sand was 17.3°C. The dune is an aeolian deposit of fine sand about 1/2 mile long, about 200 yds. wide at its widest point, and with a maximum height of 50 ft.+. Eastwardly it tapers to a wash running about N.-S (at that point); East of the wash is another, lower, smaller area of fine sand. The dune has scattered Creosote Bushes, and clumps of Eriogonum - as well as another low-bush (more thinly scattered). I set up the snake trap (100 ft. of 12" ht. window screen drift fence with a double core traps) on the N slope of the dune near the top. At about 8:00, saw and missed a young Utma. At about 8:30, shot an adult. Temp. of animal = 37.4°C.; temp. of sand in sun = 40.6°C.; temp. of sand in shade = 22.6°C.; temp. at 6" (in sun) = 28-29°C.

I walked E. along the dune, across the wash at the E end, and over the sandy area E of the wash, where I took a Verdin from a Creosote Bush. Then I walked N onto the hill N of the dune; found a Dophrne agassizii here. Returning to the dune, met Dr. Miller and walked back to middle of dune. Collected 3 Cnemidophorus (from about bases of Creosote Bushes), and one Callisaurus draconoides. Left Dr. Miller saw one Urosaurus in a bush, Dr. Miller collected it. Left Dr. Miller and walked back to road. Returned to Cottonwood Springs and prepared specimens. At about 5:00 P.M., went with W and Russell to set stakes along road leading S. to Phoenix - Indio H'way. Returning from the H'way to camp, I rode on the fender of the truck, checking the road for herps. Took one DOR Colonyx variegatus from surfaced road near the H'way. Saw no mice.

She described, among other things, what must have been a White-Winged Dove, and what may have been a Clark Nuttacker, each had hung about their house earlier in the year. Walked to mine about 1 mile 5E of the house; this is a shaft in hard rock, about 100 ft. long, slanting down at an angle of about 50°-60°. There were no bats and was no bat sign evident. Enroute to the mine, the road passes through a wide place in a wash where milling (?) for the mine may have been done. There are remains of several building and heavy scaffolding. Much lumber and junk was turned in this area without producing more than $25s. Several Eucalyptus trees, about 5" in diam/2" above the ground, were seen here; one is apparently doing well; one shows a little green; two look quite dead. Returned to Cottonwood Spring via the wash-canyon leading down to it from above. Collected a ? Rufous Hummingbird from the wash about 1/4 mile above the (Spring) Pontalimon?) spring. Much Monkey Flower (?) was in bloom in this area. Swinnina auriculie.

Kendrickson 1950 Journal Sept. 14 Cottonwood Springs, 3040 ft., Riverside Co., Calif. Took 5 a.m. Bufo punctatus from base of rock ledge at spring. After dark found 5 large Bufo punctatus on and near damp spots at bottom of rock ledge near spring and around pipes leading from spring. Ward Russell took one female tinnet from under palms, using a butterfly net. There seemed to be a number of tinnets roosting in the palm fronds; no other birds were noted roosting there. Sept. 15 1 mi. W & 3 mi. S Pinto Mt., 1750 ft., Riverside Co., Calif. Ward Russell and I left camp early and drove to a point near the dune, walking to the dune itself and arriving at about 6:20 A.M. There was one small Chionactis in the snake trap; one other trap had the contained sand disturbed, indicating an animal had entered and escaped. Several lizard and snake tracks could be seen following the fence; one followed to the end of the fence, then back the other side. I feel that the fence principle is a good one for concentrating animals - the improvement needed in the apparatus used is in the cone traps (flaps on the openings?). At

Hendelsohn 1950 Journal Sept. 15 1 mi W & 3 mi S P into Mt., Riverside Co., Calif. seems, however, that this type of trap is only practicable when it can be left set up for a fairly long period -- two weeks or more, with bi-weekly visits, perhaps. Also, I wonder if small (10 ft.) forces with two traps might not serve better; they could be placed at points of maximum activity (as indicated by trackers). At 6:40 A.M. the temp. of the sand on the top of the dune (in sun) was 26.4°C. At 7:06 the temp. of the sand on the E. end of the dune (near the wash) was also 26.4°C. (about 40 ft. lower than pt. of 1st temp.) Between the two times mentioned above, we had walked from the center of the dune to the E. end, hunting, and had seen only one Crepidophorus. The Uma did not begin to appear until about 8:00 A.M., when the temp. of the sunlit sand was about 40°C. or above. I collected one small Uma, one small Callisaurus, and a large Dophornus agassizii. Left the dune at about 10:30 and returned to camp. Dr. Miller had obtained a number of specimens, and spent the remainder of the day shinning.

Ventrisheim 1950 Hyla arenicolor Sept. 5 Indian Cove, 3000 ft., San Bernardino Co., Calif. Dr. Miller and I collected 18 adults from granite pools. In first fairly steep part of canyon above pini grounds is an area of exposed granite bed rock, eroded into jumbled large boulders, potholes, and slickenslides. 5 water temperatures were taken -- all 24.8°C (about 11:00 A.M., spotty overcast day with intermittent sun and shade. The first animal, and two others of the ones I collected, were in clear granite cracks. The remainder were sitting out on smooth granite faces, mostly shaded. The tanks contained clear water and were not half-filled with sand and silt as I have seen others on this trip. The silt layer was from 1/2" - 3" in some pools; other pools were almost free of silt. Rough sketches of three common types of "niches": (g' x 3' pool, low in canyon; to 8" deep; sandy silt bottom; little surrounding vegetation) (grass 6"x12"x18" boulder (pool clear & clear, in bed rock; 3"x12'x18" deep) ledge in bed rock water level Hyla (wet and foul-smelling where found)

Callisaurus draconoides Sept. 8 3 mi. S.E. Joshua Tree P.O., San Bernardino Co., Calif. In and near large sandy wash collected three individuals. Dominant vegetation was Catclaw and Desert Willow, with some Burro Brush on the wash margins. Temperatures were as follows: Callisaurus = 40.8° C. sand = 38.9° C. 6" above sand = 32.0° C. (shade) Callisaurus = 41.2° C. sand = 49+° C. 6" above sand = 38.5° C. Callisaurus = 40.8° C. sand = 46.5° C. The animals were very active, some ran as much as 50 ft. away, disappearing still on the run. Animals which stopped while still in view were not observed to show the tail-waving action commonly observed by me in animals observed near Tucson, Arizona.

Hendrickson 1950 Crataealus mitchelli Sept. 7 Stubby Spring, 4500 ft., Riverside Co., Calif. At about 4:00 P.M., after warm, sunny afternoon, found large (3'-2) male stretched in a straight line across the sand of the canyon bottom about 25 yds. below the large tank. I approached slowly and could detect no disturbance of the snake. It was absolutely motionless -- not even the tongue flicked. Even during this apparently completely relaxed basking, however, the tail was elevated slightly. [Sketch] Upon closer approach (than about 10 ft.), it proved very active in seeking cover. Upon being rapped out from under a scrub oak onto the sand it showed considerable fight and was difficult to secure in hand. The temperature was 26.6°C. The temp. 6" above the sand was 23.5°C.

In main canyon at point above camp where it widens out into a fairly broad trough, I collected 4 individuals. The soil here is the type of sterile - appearing small-gravel (eroded granite) common in the area. In the bottoms of minor washes it assumes more of an alluvial character. The vegetation is pinon-juniper, rather thinly distributed, with burro brush and some manzanita. All four individuals were on bare gravel, and ran under plant cover when approached. The one large animal was in a manzanita patch; the other three in burro brush. First one found accidentally during litch-collecting; other three were result of concentrated two hour search. One upon having formalin injected into it under some pressure, disgorged a large quantity of dark brown winged insects which I believe were alate termites. Many termites were in flight at the time.

Kerleibson 1950 Sceloporus occidentalis Aug. 26 Lower Covington Plate, 5000 ft., Riverside Co., Calif. At water hole in canyon S. of camp (actually, canyon emptying into first wash S. of camp), while watching for birds, noted medium-sized individual running on rocks on S. wall of canyon, about 10 feet away. The rocks on which it was running was covered spottily with reddish lichen; soon after I began watching it, it moved about 6" in one dart and picked up something from the center of a patch of red lichen. Upon my moving a hand to my face to dislodge a fly, it whipped around facing me and froze for about 30 seconds, then bobbed rapidly 5 times. Presently it moved back to its original position, bobbed three times, then four again. After he appeared to be fully settled down again, I intentionally moved my hand upward about 6". He reacted instantly by changing position, and I am certain he saw the movement. For about 5 minutes thereafter it remained almost motionless, then I shot at a Pipistrellus flying overhead,

Stubby Spring, 4500 ft., Riverside Co., Calif. September 7 In first small canyon E. of spring watched 7 individuals foraging on sandy floor of rock-walled canyon. Fairly heavy, soaking rain the preceding day; every- things moist. Overcast until about 8:00 A.M. Heavy flight of termites—the animals seemed to be feeding mainly on these. All were moving about jerksily with short darts of about 12" or less. All were seen to move up onto the rocks at the sides of the canyon at times, but by far the greater portion of time was spent on the sand. A decidedly preferable “perch” seemed to be the exposed part of a rock which was submerged in the sand of the canyon bottom and projected 2"-5" above the sand surface. The sandy area of the canyon bottom was from 10'-20' wide; the 7 animals noted at one time were

They were seldom noted in close proximity to each other, but there was no indication of any exclusive territoriality; the animals often passed each other and changed their order in the linear arrangement on the canyon bottom. One animal was seen to move about 40 yards up the canyon during the period of observation, passing three other animals en route. At about 8:00 A.M. (sky temporarily overcast) the sand of the canyon bottom was 20.0°C. The temperature of an indiv. shot at this time was 25.2°C.

Hendricksen 1950 Uma scoparia Sept. 13 & 15 [mi. W. 8 mi. S. Pinto Mt.,] 1750 ft., Riverside Co., Calif. Two mornings on the dune have given little real acquaintance with the animal; the following fragmentary notes are all that seem definite enough to record: - distribution: On areas of fine, wind-blown sand only - not on areas where fine sand is mixed with gravel or rocks, and not on areas where fine sand has been pocketed by rain or runoff water. - activity: Began at about 8:00 A.M., when temp. of sunlit sand was about 40° C. Early, animals did not seem so disposed to run down holes as later, but more often stopped in the open. Late in the morning, they invariably seemed to disappear down Dipodomys deserti holes. Efforts to wait for them to reappear from the holes were fruitless. Two 20 min. vigils discouraged me. One concerted effort to dig out two adults seen to vanish down the same hole also proved fruitless. - location: on main dune, especially E. end, and on gentle slope E. & S. of W. & S.W. of main dune. - young: Several small individuals were seen, all rather early in the day.

These showed less tendency to run long distances, and were more inclined to enter holes (not available without running to across open spaces?). They tended to hide in the clumps of Wilaria (Eriogonum) which grow in hillocks all over the dunes. -habits: A rather marked "home range" limitation might be indicated by the actions of several animals which, when disturbed, did not run straight away from me, but circled at a distance of 10-20 ft., running swiftly to a hole. Other holes were twice in plain view, but the lizards circled me 100°-180° in order to reach another. Some holes seen had many lizard tracks at the openings, others had none.

Harbuckson 1950 Empidonax (traillii?) Sept. 9 Stubby Spring, 4500 ft., Riverside Co., Calif. While seated near the large tanks at the spring, I twice saw Traill (?) Flycatchers (different individuals) bath in the tanks. The circumstances are sufficiently new to my experience to warrant mention here. In each case the birds flow from perches or the bush overhanging one side of the tank to the center of the open water, landing with a splash and taking off again almost immediately. Returning to the perch, the ruffling and fluttering of a "typical" bath occurred, followed by industrious preening, then the birds returned for another wetting. One bird "bathed" four times, one twice. The water is about four feet deep in the tank. Although there seem to be a few spots where small birds might stand and bathe (niches in the rim of the tanks), I saw no birds using them. About 20 feet up from the tank is the seep, where there seem to be good bathing spots. The hazards associated with birds such as these flycatchers bathing in deep water might be indicated by one

Later, while trying to determine possible effects of different chirps and squawks on Pipistrellus flying nearby, a lory bird flew in and lit about 10 ft. away. It flew about 20 ft. further away and lit behind a rock. I levelled the gun, chirped once, and shot it as it rose.

Many times individuals flew to within a few feet of where I was sitting in a niche in the sloping canyon wall about 20 ft. above the canyon floor. One was seen catching a muscid fly which was noted before the bat appeared in my field of vision. Several times bats caught insects and flew toward me, "cleaning" on them with seemingly exaggerated chewing jaw movements. A difference was noted in the sound made by their wings as they flew close to me. One was identifiable by a sound considerably higher than the others (hole or tear in wing?).

At 9:45, when I left, I went to the crack where the bat disappeared, found it and collected it alive. Experimented with various whistles, squeaks, etc., to see if there was any noticeable effect on the bats. During this time, I laid my loud-ticking pocket watch on a rock ledge nearby; almost immediately three bats appeared and fluttered close as if investigating the sound. Repeated removal & return of the watch produced no results.

Hendrickson 1950 Eulaimias merriami Aug. 26 Lower Covington Plate, 3000 ft., Riverside Co., Caly. While watching near water hole in canyon emptying into first wash S. of camp, an individual appeared about 10 min. after I had become settled. It charged continually at me, intermittently edging toward the water, then running back closer to cover in the rocks. Eventually it moved down to a near-vertical face above the sloping pit in the sand, at the bottom of which was the water. It either lost its footing on this vertical face or intentionally dropped down to the sand. I had just finished digging out the water hole, and continual slides of sand had left a smooth, steep slope of loose material. It was on this the animal landed; it started another slide and ended in the water. Apparently badly frightened, it ran wildly up the sliding sand of another slope of the pit and disappeared among the rocks. It was not seen again.

Hardwickson 1950 Canis latrans Aug. 26 Lower Covington Plate, 5000 ft., Riverside Co., Calif. Found a young male in steel trap set on coyote trail in sandy wash (1st wash S. of camp). When I first heard and saw it, it was bucking and jerking actively. As I approached to about 15 feet, however, it stopped trying to escape and came toward me as far as the chain permitted. It showed no curled lip and made no sound, acting like a pet dog hoping for relief. My first blow (perhaps half-hearted) did not kill or stun it, and it ran as far away from me as the chain permitted. It growled several times as it died.
