Bowman 1952 Journal Aug. 11. 11.5 miles NE Chama, 10,000 ft., Rio Arriba Co., San Juan Mtn., New Mexico. The following is a brief resume of the happenings during the last 8 days. The MVZ party, consisting of Ward Russell, Jerry Russell, Stuart Randry, and myself, left Berkeley on Aug. 4 about 5:30 a.m. Both MVZ panel trucks were taken. First night camped 80 miles W Needles, Calif., on the desert. Temp. that night well up in estimated 80° F. Slight cooling at sunrise. Camped on the outskirts of Gallup, New Mexico. Slight rain that night. On the morning of Aug. 6th we crashed the '47 Chev. truck at San Ysidro, New Mexico. Stuart Randry was driving when accident occurred. (Randry was not in possession of a valid driver's license). I was injured slightly and taken by ambulance to Grants Hospital, in Grants, New Mexico. Here I remained until the morning of Aug. 8. During this 2 day interim, the remainder of the party attended to repairs of truck, and storage of surplus equipment at the University of New Mexico in Albuquerque. On leaving Grants, N Mex. on Aug. 8, we drove (4 in cab of '51 truck) to Albuquerque where we camped on the desert east of town. On Aug. 9, we remained in Albuquerque during a.m. for shopping and awaiting estimate of repairs on truck ($50). In afternoon we drove to Santa Fe where we picked up mail and obtained directions on camping localities in the high country in Northern New. Mexico. We made camp at Bravos Lodge, 6 mi E Parkview, at about 8000 ft. On the morning of Aug. 10, we surveyed the immediate vicinity of camp. The dominant tree here is yellow pine. In an hour of hiking around camp, saw or/and heard the following animals: nighthawk (3+); broad-tailed

(?) in some location. The latter 3 animals were discovered by Ward + Jerry Russell. By mid-morning we proceeded northward to Chama. Here we made enquiries into means of entry into the high country of the San Juan mountains. Finally we entered the locality given at the heading to page 1. by driving into Colorado & then southward over a poor dirt road . This general area is called the meadows of the Brazos River. After a preliminary survey of the area, we made camp beside a small stream at 10,000 ft. Between 5:30 - 6:45 P.M (mountain standard time) I set out 60 Museum specials along the stream + 30-40 ft above the stream on steeply sloping, blue spruce-studded hills. Used chewed oatmeal as bait. While setting out traps saw 1 or Western Tanager, Mt Chickadees, Ruby-crowned Kinglets, Juncos, and Chickarees. During the early afternoon in the area of the meadows, saw 15+ Turkey Vultures, Ravens, 1 Goshawk (sitting in a Blue Spruce in open grassland) and several Horned Larks. In one of the small streams (locally famous for the trout fishing) saw many small (2-4") speckled trout (Salvelinus fontinalis), as identified by the light edging to the pelvic + pectoral fins. The waters quite cool (below 50° F estimated), and the streams have good deeply cut banks. This area, primarily Canadian life zone, reminds one of the mountain country surrounding Lake Okanagan in British Columbia. The former is at 10,000, while the

Bowman 1952. Journal 3. Aug. 11. 11.5 miles NE Chama, 10,000 ft. Rio Arriba Co., San Juan Mts, New Mexico: former at 7000 ft. of course the plant species are different. (Photo to be taken at a later date). In general the topography is gentle to steeply rolling, covered with soil. One is impressed by its park-like appearance. Small groups evergreen spruce [Picea pungens - Blue Spruce] and (Engelmanni) Engelman spruce) occur throughout area. Small and some fairly extensive stands of Populus tremuloides occur mostly on the S.E. slopes. Picked up traps at 5:30 a.m on Aug. 11th. Caught The following : 6 Kerompeus maniculatus, 1 Sorex palustris (on small gravel-sand bar at edge of stream), 1 Cleithro- nomys gapperi . During morning walk (6:45-10:30 A.M.) saw observed the following animals or their signs : Red-shafted Siskin (2), Sparrow Hawk (3:2 ad + 1 im.), 4+ Western Wood Pewee (collected). Ravens (6+), mountain chickadees (numerous---most ubiquit- ious bird in area, from tops to bottoms of spruce trees, in poplars) -- Saw what is probably the nesting site of this species. It consisted of a tangle of spruce twigs about 7 ft. from ground with a small hole on one side. Two [illegible] birds were seen in the immediate area of the nest but not seen to enter; Junco (3+; shot an im.); heard + saw red crossbills (3+) flying overhead; shot one im. Audubon Warbler in the upper reaches of a spruce; the wood pewees were almost exclusively restricted to the poplar groves, where they were giving their hissing

Bowman 1952 Journal 4. Aug. 11 11.5 miles NE Chama, 10,000 ft, Rio Arriba Co., San Juan Mts., New Mexico: numerous Pocket Gopher diggings in area. This might be due to the considerable depth of soil, which is very humous and moist. There are essentially no rocky outcrops and but a few gravelly areas, except near streams. Saw several chipmunks (Eutamias amoenus) scurrying & calling in spruce groves, usually where considerable dry fallen limbs + logs. Rabbit droppings are everywhere in and around trees. These are fresh. I shot one adult Snowshoe Rabbit. It was extremely tame, & would run only a few yards when alarmed, & then stop, making shooting with a .38 shot shell very simple matter. During the early morning hours just before it became light (approx. 4:45 A.M.) and again at 8:00 P.M. heard Horred Owl hooting. The other party members saw the following - Pine Grosbeak, Pileated Woodpecker, Canada Jay, Chickaree, Mountain 3-toed Woodpecker. It should be noted that the weather here has been most unpredictable so far. Usually the mornings are clear & sunny, with heavy dews. By 11:00 A.M. cumulous cloudbanks appear and scattered thunder showers prevail until midnite. The temp. is ideal for hiking, & cool for sleeping. No readings taken as yet. The average height of the mature spruce tree (sp.?) is 50 feet. At 7:00 P.M. set out 22 MVZ species at the edge of a 1 acre meadow beside camp. Some traps placed at bases of spruce which were immediately bordered with moist grass covered meadows. The majority of the traps (12) were located on dry ground along logs + stumps. Heavy thunderstorm at 11:00 p.m.

Bourman 1952. Journal 5 Aug. 11 11.5 miles NE Chama, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico: The following are a few bird temperatures taken: im Junco - 10 sec. after shot (dead) 40° C at 7:20 A.M. Wood Pewee al - alive, but wounded 39.2° C at 7:40 A.M. Audubon Warbler - im, alive but wounded 40.3° C at 8:15 A.M. Aug. 12: Arose at 5:05 AM. (MST). Caught one Cleithronomys and one Zapus in trapline (22 Museum Speciale). Both animals were caught at edge of small meadow south of camp at the base of spruce trees. Heavy rain during evening. Hiked around camping area from 7:30 A.M to 9:15 AM. Observed the following species: 3-toed woodpecker (1), red-shafted flicker (3+), Goshawk (1), horned owl (2+), wood pewee (2+), mountain chick- adée (x), red-breasted nuthatch (1), ruby-crowned kinglet (3) pine grosbeak (6+) -- giving 3-syllabled call while in flight; birds always landing on the uppermost branches of spruce or fir. red crossbill (1), red-backed junco (x) - many young; chipmunks (2), chickaree (3). Animals recorded by other party members, as follows: Crow (1 shot by W.C. Russell), Veepor Sparrow (1 shot Canada Jay (2 shot by Indy) by W.C. Russell], Williamson sapsucker (1 shot by S.O. Landry), 1 / pocket gopher (trapped by J.C. Russell), / Amblytona sp. (caught by J.C. Russell as it entered a gopher hole at 10:00 am). Bird- life found most abundantly at edges of forest stands, and in small groups of fir & spruces in open grassland. Many flowers in bloom on grasslands, i.e. purple daisies, yarrow, blue bells; on the more shaded slopes found a purple-flowered vetch and Indian paint brush. Many large mushrooms (up to 10" diam), with white spots on a brilliant orange- red background, growing on open slopes & in open wooded areas.

Bourman 1952 Journal. 6. Aug. 12. 11.5 miles NE Chamas, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico Abundance of grasshoppers, which don't appear in flight until about 9:00 A.M. Large ants are frequently encountered measuring 1-1/2 ft. in diam. There are some mosquitoes which are noticed primarily in early evening. Temperatures are cool enough at night to keep them inactive. Temp of air taken at 7:55 A.M. (MST) in shade of spruce on east facing slope. Learned how to distinguish the local spruce & fir trees. Character Spruce (Picea) Fir (Abies) a. shape of needles - squarish in x-sect. . : flat in x-sect - b. color of cones (?) - reddish brown-hanging; dark grey-vertical c. color of bark (mature tree)- reddish background: light grey, bark similar to yellow-pine tree smooth. Bark rough Looking north to Colorado (2 miles North of camp) could see 3 small snowfields on SE slope of mountains, possibly 5-6 miles distant, and an estimated 1000 ft. higher than our altitude here (10,000 ft.). This area about camp is grazed by a large herd of sheep, thus polluting much of the small streams. The owner ('[name]') dropped into camp & reported that there are many small (6'-8") trout in the streams; few large ones. The local game warden (camped 1/2 mile from here) reports 40+ elk in area, wildcat, 4 Coyote, 7 black foxes. He (Mr. Owens) said that the rabbits & grouse are "low" in numbers this year possibly due to the heavy snowfall last winter -- 70 feet! lying 40 ft. deep! Called horned owls tonight. Saw 2 & heard one other. One bat in flight around camp at 7:35 pm. No others seen. Post Script - Ward Russell brought in a marmot skull. S.O. Kendry found porcupine quills on spruce.

Bowman 1952. Journal 7. Aug. 13 11.5 mi. N.E Chama, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico Pickup of 26 traps yielded 1 clethrionomys. No rain last night, although a few traps sprung. From 7:30 - 11:00 A.M. (MST) observed the following animals: Crossbills, mountain chickadee, Canada Jay, Wood Pewee, Williamson's Sapsucker(1), Pine Grosbeak (3), Audubon Warbler (1), Sparrow Hawk (2), Red-tailed Hawk (2), Red Shafted Flicker (2), Robin (8) - adm. Ruby-crowned Knight White-crowned Sparrows(3), Pine Siskin(3), Crow, Turkey Vulture(1), 1 Chipmunks seen at least 10 ft. up in spruce tree. Coylete (skull only picked up in stream); many pocket gopher diggings in meadowa. Made 4 sets of gopher traps (6 traps) in open fields directly north of camp. Soil very deep, rich, block + moist with plenty of humus - south exposure. Robins were seen in abundance in protected meadow 1 mile N of camp alongside stream. Several immatures seen heard. Two unidentified swallows seen flying high over stream at state border (Colo. - N.M.). Jerry C. Russell shot one Violet-green swallow so it is possible that the two birds I saw were of this same species. The two Red-tailed Hawks seen north of camp, acted in rather unusual fashion. One bird landed on the grassy slopes & beside stream & was seen to hop around on the ground half hidden by the long grass. It uttered the characteristic long hissing note. At state border observed the only willow seen in the area. Since it was at the stream bottom, it was a hundred or more feet lower in elevation than most of the surrounding land. Western Wood Pewees were seen in large numbers feeding at edge of poor spruce-fir woodland, perching on dead trees only.

Bowman 1952 Journal 8. Aug. 13 11.5 mi. NE Chama, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico On wooded slopes, found extensive areas of tree falls. Much of these fallen trees have rotted away providing very suitable habitats for salamander. However none have been found after considerable effort. Much insect food under rotting logs. Water temperature of stream beside camp at 7:30 A.M. in shade, 48°F. Air temp. in shade in some locality, same time, 51.5°F. Slight rainfall during afternoon today. Morning clear, warm, slight west wind. Animal observations by other party members (today): Brewer Blackbird (1 shot), Steller Jay (1 shot), Violet Green Swallow (1 shot) -- all by Terry C. Russell. T.C. Russell also found the remains of 3 rabbits in the woods during past 2 days. Possibly these were taken by owls. J.C. Russell saw one bat fly by camp at 7:40 P.M. (MST). -- almost dark. Ward C. Russell found a small horned lizard (about 2" long) under our truck, on gravelly clay soil during morning. WCR reported hearing Olive-sided Flycatcher in the past few days and yesterday, he saw 2 House Wrens. Yesterday, visitors to the camp reported seeing what we decided were water ouzels along streams, about 1/4 mi. SE of our camp. I saw none today in hiking along one mile of stream north of camp. Several small trout (4"-5" estimate) seen in the shallow water (no more than 10" deep most places). At 6:00 P.M. set out approx. 40 Museum Specios along streams for shrews, and neighboring trees, a loop for Peromyscus et al. One owl(?) pellet picked up by Lonbry contained the fore-limb of a pocket gopher(?).

Bowman 1952 Journal 10. Aug 14. 11.5 mi. NE Chama, 10,000 ft., Rio Arriba Co., San Juan Mts., New Mexico. Observed the following animals: Pine Siskin, Pine Grosbeak, Red-breasted Nuthatch, Ruby-crowned Kinglet, Wood-peewee, Grey-headed Junco (J. caniceps), Chow (5+) Wood Pewee, Western Bluebird (10), Red-tailed Hawk (2) Sparrow-Hawk (2), Red-shafted Flicker (6), Audubon Band-tailed Pigeon (1) Warbler (2); Chipmunk, Chickeree, Pocket Gophers. Observed a chipmunk calling from a 5 ft position from ground in a 10 ft. spruce tree. The Bluebirds were seen on the higher slopes where extensive open fields with scattered spruce trees. Birds seem to feed on ground. Both birds shot were immatures. My gun jammed by mid-morning so collecting was restricted. The mouth of the grey-headed junco was full of small insects, seen taken on bark of spruce tree just before taken. In the gopher set captured 2 gophers, one of which was badly macerated, possibly by a weasel. Ward Russell examined some of the "stringy" droppings found at the entrance to one gopher hole which he said were undoubtedly weasel. Also, the fact that many gopher burrows were exposed to the surface, suggested that a weasel had taken over" the colony of gophers. We re-set the 2 gopher traps and one Shyler trap baited with fried fish head, hoping to trap a weasel and/or gopher. The following were observed by Terry Russell: shot 14 & im. Russel - backed through, caught one 2 1/2" long

This hill has an eastern exposure. Captured at 1:00 p.m. (MST) while in the sun; saw one Piloted Warbler, and brought in the breast bone & some thoracic ribs vertebrae of a "grouse" (identified by WCR); trapped 2 small shrews (? dusty?) in Museum specials placed at the entrances to hollow logs. The following observations by Ward Russell who spent 5 hours to the SW in the meadows of the Brazos R.: shot 1 Pica (saw another, & remarked that they give only one nasal "bleat" instead of the usual 2); shot one Red Crossbill; 2 Horned Larks, 1 Savannah Sparrow, 1 Cassin Finch; saw one Woodchuck, and heard some unknown amphibian calling from a meadow (Hyla?); 1 Rock Wren, & collected one, two ft. long garter snake. Ward caught his limit of trout (15) - 12 Brook Trout, 2 Cutthroat Trout, and 1 Rainbow Trout. Addenda: Golden- mantled ground squirrel (2) collected by Stuart Londry yesterday (Aug. 13). Today, Londry reported fresh deer droppings on a steep wooded slope east of camp, and White-crowned Sparrows. The Peronopus nanoculatus which I trapped today had a white dorsal area (1/2" long) in the center of half way down the length of the tail on the dorsal surface. Stuart Londry caught 2 Peronopus

At 5:45 P.M. set out 35 Museum Specimens south of camp in wooded marshy area. Aug 15. Pick-up of Museum specimens at 5:50 A.M.- Only one Zapus taken in meadow beside a log. Temp. at 5:45 A.M. at camp, in shade 42° F. Frost on ground. From 7:00 A.M. to 11:00 A.M. hiked the mountain range east of camp. The shaded W-facing slope is heavily wooded & damp. Found liverwort growing profusely on ground. Found golden-mantled ground squirrels digging on a rocky- ground covered plateau. Good view of the Sangre de Cristo range to the east. --- appears like a saw-tooth range, considerably higher than any of the surrounding country to the N, S, or W. This mountainous country is surprisingly flat & tame, reminding me much of the topography in central British Columbia in the N. part of Tweedsmuir Provincial Park. The plateau east of camp is approx. 1000 ft. higher than our camp, thus making it 11,000 ft.

There is evidence of greater tree growth here, for in many places there is extensive fall of trees, now grey & weathered. Annual observations as follows: Juncos (black-headed) seen frequently in trees. Shot at a family group 20 ft. off ground in a dead spruce tree. Shot one Chipmunk; aval temp. 15 sec. after shot (dead), 39.80 C. at 8:50 A.M.. Saw 10+ Mt. Bluebirds on the open grassland plateau -- flying from dead stump to stump. Young birds seen fed by adults. Blue Daisies (?) and Crossbills (Red), and 4 Audubon Warblers seen in five trees. Found a small pond (estimated 1 acre in size -- circular) containing hundreds of Necturus (?) ranging in size from 2" to 4", called "mud-dogs" locally. These amphibians were located in the shallow margins of the pond, sunning. Was able to capture only one animal. Water temp. at 10:15 A.H in shade at surface was 61. F. I estimate the pool to be uniformly shallow, probably 3 ft deep at center. Bottom muddy. Could find no frogs or toads in area -- also no kingfishers! About 10 open & spruce trees around edge of pond in 3 scattered cumps. The west-facing slope of this range, at its northerly pt., is rocky covered, ideal for cones, but found none.

Saw heard Nighthawks along ridges [illegible] nearby. Also nighthawks at our elevation. Jerry Russell shot one big brown bat. The following is by way of description of the area surrounding our campsite. The dominant vegetation is Yellow Pine, with the average height approximately 60 ft. (estimate). The stand of pine is open, with interspersions of groves of aspen. There is some logging being carried out, and in those recently logged areas we find the aspen groves thriving. The oak (sp?) takes on the form of a scrubby deciduous shrub, averaging approx. 6 ft. high, and usually in the open areas, in small stands about 10 feet square; occasionally interspersed with [illegible] the aspen. (200 ft.) At slightly lower elevations sagebrush (Artemesia tridentata) appears. The grass is not dense but reaches approx. 1 ft. high on the average. Some cattle graze the area, & their droppings, both fresh & old, are most everywhere. The soil is shallow, & gravelly, with little humus, humes. Some yellow daisy, purple lupins are in bloom. There is neither the lushness nor the variety in flowering animals which prevailed at our higher camp (10,000 ft., 18.5 mi. Chama). There were 2 light showers during the day with some hail.

Temperature in shade at 6:40 A.M. at camp, 55° F. From 7:00 - 9:30 a.m. (M.S.T.) observed the following: Pygmy Nuthatch (these are the most ubiquitous birds in area, found primarily in the yellow pines They occur usually in flocks of 3 to 10. They utter several notes & calls. I have noticed a plaintive, quiet trill given when in flocks & preparing to leave for another tree feeding station. At other times a solitary bird will give an oft repeated two- parted reedy whistle. I am taken with the striking resemblance between this species of nuthatch's woodpeckers, in flight, pecking habits, etc., and relative tameness. Whereas at our Chama camp, juncos were the most conspicuous and not probably abundant small bird life, here at our Tres Piedras camp, the pygmy nuthatch forms the dominant bird species. Another note given by the pygmy nuthatch is almost finch-like in quality, given usually, but not exclusively, while feeding in small groups (2-3). This is frequently the only clue to the presence of this "mite" of a bird) Solitary Vireo (taken in open grove); 1 Calliope Hummer Steller Jay (2), White-breasted Nuthatch (2), Western Bluebird, Siskin, Williamson Sapsucker (1), Orange grey crown Grosbeak Warbler (taken), Black-headed Juncos,- - (young adults) -, Clark's Nutcracker (3), Violet-green

They are at present logging yellow pine, so that the stands are open, somewhat like a park. The oaks are small & scrubby. I found underneath pines, also in aspen grove. Young pines are found coming up under Aspen! Fir are virtually absent, although Stuart G. Landry report finding one nearby. The following are some birds & mammals reported by other members & not as yet seen by me: Golden- mantled ground squirrel, Chipping Sparrow, badger digging, House Wren, Red-tailed Hawk, Spotted Towhee, Black-headed Grosbeak. Meet Flycatcher, I remained in camp this evening, while others went after, porcupine, Owls & bats. Aug 23 From 6:50 - 11:15 AM hiked about 4 miles SE of camp, descending possibly to the 800s ft. elevation (no altimeter reading taken.

Bownow 1952. Journal 22. Aug. 23 3mi SW Tres Piedras, 9000 ft, Rio Arriba Co, New Mexico. Was impressed by the large numbers of warblers passing through area. Observed chiefly on the hill tops in yellow pine & aspen. Usually seen in small groups, feeling very briefly & then moving on. No definite N-S movement apparent. Today I observed large numbers (20+ at one time) Pygmy Nuthatches feeding in aspen groves. Birds were exceedingly tame. I could approach to within 3 feet of birds while "squatting". Although few birds were killed today, much of my time spent in exploring the distribution of major tree types. At an estimated 8000 ft level noted the following trees & shrubs growing within a 1/2 acre plot of land: yellow pine, a juniperus?, a fir (sp?), aspen, chrysothamnus, & sagebrush. Here we have an upper sonoran plant (Juniper) growing side by side with a Canadian (fir) type species. How does this fit the life-zone concept? Found one small group of 10 fir trees growing on exceedingly rough terrain -- 3 ft boulders & a NW exposure. Trees were all mature & about 50 ft tall. At nearby found 1 Ground Squirrel & 1 Chipmunk found among rocks. About 3/4 dist out found several 6 ft. fir trees growing up under a dense stand of aspen. Obvious signs of lumbering & grazing. No sign of a house. On the W facing slope, just over the crest of a hill, found oak growing to a height of 15 ft, with a basal diameter of 10 inches: Discovered a shallow lake,

Bowman 1952 Journal 27. Aug 26. Termez Cr., 6 mi. NW Blond, 8500 ft., Sandoval Co., New Mexico. From Tres Piedras drove to Espanola, and then via highway no. 4 to Los Almos. From Los Almos (where we were not permitted to enter the city) we drove to our present location passing through "Grande Valley", a large meadow, several square miles in extent. Found over 20+ sparrow hawks sitting along the fence posts here. Previous to this, on N side of Rabbit Mt., 9000 ft., Sandoval Co., N.Mex., found a small pond, 1/2 feet deep, and about 1/8 acre in size, where I collected 1 Hyla (WCR catalogue) & J.C.Russell collected one large Amblyptoma tigrinum here beside a rock. By the appearance of the one of the rotten log nearby, & the apparent "turnover" of all likely rocks & boards, some other "herp" collectors had recently stopped at this location. At 5:00 P.M. set out 26 Museum Specials (oatmeal bait) along Termez Cr. & along the canyons, beside rocks (granite) and at bases of Douglas Firs & Blue Spruce. Could get no response from Horned Owl or Screech Owl (M.S.T.) calling after dark. By 7:00 P.M., it is now dark. Observed the following animals around camp in early evening: Steller Jay, Gimpco, Chipping Sparrow, Chickadee (Mt.), Chickadee, & Golden-mantled Ground Squirrel. Aug 27. Temp. at Comp., 5:40 AM, (M.S.T.) was 45º F. Much cold air drainage into valley where camped. Quick warm- up when sun arose over mountains at 7:00 PM. Caught a total of 13 mice in 26 sets of Museum Specials

Brown 1952. Journal 28. Aug 27. Temez Cr., 6 mi. NW. Blond, 8500 ft., Sandoval Co., New Mex. 3 Microtus longicaudus on gravel bordering stream, where grasses + an umbelliferous plant form dominant vegetation. (See Photo's 2/8 and 2/9.) One trap set very close to water (for shrews) caught one Microtus. The water level of the creek had risen during the night so that the trap with the mouse were partly wet. This microtus apparently prefers a very moist habitat and might even be partially aquatic. Along the bases of graniterock on N facing wall of canyon, caught one shrew (Sorex sp.). On the S facing slope of canyon, two spring traps showed a tail and a foot of a shrew. Many of the traps were apparently dragged away by the mice (shrew?). Caught one large ad. Peromyscus boyli(?) and 7 Peromyscus monicaulatus (4 of which were immatures). One large Ambystoma tigrinum in Museum Special (later lost before preserved). Salamander taken on S facing slope at base of large granitic boulder, about 75 ft. above stream. (James Cr.). Ground covered with fir needles. Observed the following birds around camp: Ruby-crowned Kinglet, Grey-headed Junco, Steller Jay, Line Siskin (very poor worn plumage-- nomoult as yet), Mt Chickadee, Pileolated Warbler, Chipping Sparrow; (Temp of Chipping Sparrow, 5 sec. dead, at 10:25 A.M., 41.5°C). About 1/4 mi. upstream from camp, discovered a beaver dam made of 5 inch logs (Tim.) showing beaver-cut ends, stones, coffee & beer cans. Some grease + roots also incorporated. Dam wall about 8" thick.

Bowman 1952. 30. Journal Aug. 27. James Cr., 6 mi. NW Blund, 8500 ft, Sandoval Co., New Mex. Found a second beaver house about 100 yds. upstream from previously described house. This "house" was about 6' high made of logs & twigs. The largest log measured an estimated 12" across. The house was built between two large rocks. Saw fresh beaver tracks nearby suggesting activity around this house. See photo 2/12 for unique beaver cutting of a Douglas fir prepared for felling in a narrow area between two rocks. Shot one House Wren at 12: noon. Temp after 2 sec. dead was 41.0 C. Saw 2 other House Wrens along creek. At 6:40 P.M. set out 25 Museum specimens along S. facing slope of James Creek at base of rocks & Douglas firs. -- none along stream bottom. At 7:15 A.M. Saw 1 small bat (P?) fly low over camp. No owls would answer calling this p.m. Valley floor here has a good humous soil with many pocket gopher diggings. SCR. trapped 3. Chipmunks and Golden-mantled ground squirrels seen in rocky areas along stream. Aug. 28/31. 6 mi. S Bernalillo, 5500 ft, Sandoval Co., New Mexico The following is a brief survey of activities during the previous 3 days, as reviewed from notes taken in the field: Aug. 28 -- James Cr. 6 mi. NW Blund, 8500 feet. From 7-8 A.M. turned over decaying logs and bark in spruce-fir wooded slope S. of camp. No Plethodontidae found. Many ants, beetles, centipedes noted under them. Noted that the fir-spruce tree association gives way.

Apparently we are noticing a local 'inversion' of the life zones possibly due to cold air drainage into the valley where we are camped. Grey-backed Junco, Mt. Chickadee and House Wren observed in the spruce-fir association. The ground is moist and there is considerable mossy growth on soil. Yesterday (Aug 27) Ward C. Russell captured 3 plethodontids here. Captured the following in the 25 Museum Specials set out on a steep S-facing slope of T Jemez Cr.: 3ad & 3im. Peromysc sp. & One Lark Sparrow shot by WCR at camp. [T emp. at 10:00 AM, drying was 41.4°C]. One Turkey Vulture noted at 2:00 PM. While hiking upstream on Jemez Cr. for a distance of approx. 1 mi. discovered two more Beaver dams -- one made of stones alone piled about 1 ft high across stream, and a second made of small logs and stones. Also discovered another beaver house, apparently occupied (as evidenced by the freshly cut matted grass immediately at the entrance to house). Found the humerus and tail vertebrae of a 'young' (?) beaver near this house. Captured 2, 2" long (body length less legs) Rana boylii & saw several large tailed & legged tadpoles presumably of this species in Jemez Cr. Saw at least 2 House Wrens along the creek. Was greatly impressed by the active 'bouncing' action of the House Wren -- alternating left with right leg -- 'rapid pairing'?

Bowman 1952 32. Journal. Aug. 31. 6 mi. S. Bernalillo, 5500 ft., Sandoval Co., N.M.--[Sept. 30] One House Wren and an fin. Junco were very tame while skinning. Both birds entered the log huts in which we were working. The junco remained around camp continually; I was fed rice + pieces of bread, none of which it accepted. The bird was seen to take exceedingly small pieces of food. Chuckaree, Chipmunk, + Golden-mouthed Ground Squirrel were noted around camp. In the late afternoon captured 2 garter snakes along grassy- rocky borders to ste Tenes Cr. Dogwood, Gooseberry, Purple-flowering Raspberry, Snowberry, + Sambucus are common along edge of stream. Stuart Handy captured 4 Horned lizards about 200 ft. up from N. edge of Tenes Cr., below Yellow Rhinastataks. During the early evening Peromyscus maniculatus were caught in "Museum Specials" set inside log shelter. Heavy rainfall during night of Aug. 28. On the morning of Aug. 29, S.O.B. reported 5+ Peromyscus maniculatus captured inside log-shelter. Left our Tenes Cr. Camp at 10:00 A.M. + proceeded to Santa Fe via Bland. Passed by type locality for Stebbins + Renier race of Plethodon neomexicanus -- [boulder here] downing to lower elevations we noted a very deep granite- walled canyon + 6+ White-throated Swifts flying by at a great speed. Spent the remainder of the day in Santa Fe area --- opening day of the grand fiesta. Camped just north of Santa Fe in the pinons.

In afternoon made camp at our present location, viz. 6 mi. S. Bernalillo Co. NH. in a Cottonwood Grove just east of Highway # 85 along the Rio Grande Valley. Set out 18 "Museum Specials" along fence line, about 20 ft. distant from an irrigation ditch. Cactus, & other desert scrub vegetation fairly dense. Observed one Kengaroo rat (?) at 6:35 P.H. (Sunset) rune below vegetation. I may have fleisbed the animal from out of its resting place . The moon is now 3/4 full. Set another 40 Museum Specials along the underneath the Cottonwood trees where close vegetation cover is non-epistoul. Carried the line along the edge of the irrigation ditch for 6 trips. Used oatmeal. Soil very light dusty & clay-like when wet. There are numerous quots & mosquitoes in the early evening. Cicadas commence to "sing" about 10 minutes after sundown & continue till almost dark. Grasshoppers are also abundant. Saw one nighthawk at dusk. Heard and saw a large bat fly around our camp after dark . W.C. Russell shot one Screech Owl in Cottonwoods. Saw 2 Road Runners just east of camp. Bird in excellent plumage & called responded well to calling. Russell claimed this bird to be a male because of the pitch as compared to another Screech Owl in the same area. Upon seeing, it turned out to be the opposite sex as claimed on the basis of voice.

(See page 30) During afternoon of Aug. 30, we Russell drove to the Univ. of N.H. after leaving Terry Russell, Stu Hendry & I in camp. He picked up our surplus equipment which had been stored there, & deposited them with us. He & Jerry plan to leave for Berkeley tomorrow A.M. in order to be booked in time for the opening of deer season in California. Stu & I will take the bus to Albuquerque on Sept. 2. & pick up the repaired truck & O.P. Pearson. Aug. 31 - Ward & Jerry Russell departed at 7:00 A.M. Caught 1 Ouachitup, & one small Perognathus along fence line set. 5 other traps were trapped 4 of missing. Caught no mice in set under cottonwoods. Also caught one Scaphiopus in trap line along fence. There were many birds in cottonwoods in morning. Apparently a migration of warblers: The Rio Grande valley should make an excellent pathway for migrating birds (a N-S direction at this locality). The following species were noted: Rileyated Warbler, (the most abundant species today) Yellow Warbler, Grace Warbler, Solitary Vireo, Goldfinch (sq?), White-breasted Sparrow Hawk, Mourning Dove, Hatched Nuthatch (?), Hairy Woodpecker (2), Smelled one Skunk. Blue-tailed Skunks observed in fair abundance. Very difficult to shoot with .22 shot shells without injury. The screech owl shot by Russell last night contained many grasshoppers in its stomach. Shot another screech owl in cottonwoods by camp in evening. Damaged specimen so badly, it had to be discarded.

From our tent heard scaled Quail calling. Sounded very much like the 'jipping' of a dog. Mourning Doves were seen frequently, + many took refuge in the Cottonwoods to escape the hunters, this the opening day of the Dove season. At sundown (6:30pm) set out approx. 30 Mouse traps in a small wash east of camp. Used peanut- butter bait. While returning from the set in the (7:15 PM) light of an almost full moon, saw one Perognathus florus hop along edge of wash in the shadow of some Chrysothamnus bushes. Could have seen the mouse moving amongst the bushes. Later (10:15) trapped this animal in a trap placed in the shade off from the moonlight. Scophiops were seen in good numbers again this evening. They seem to appear shortly after complete darkness has fallen & then are to be found near the irrigation ditches, on sandy areas amongst vegetation, + in open unsheltered spots. When picked up they usually struggle little 'rather curious' and inflate their bodies. When in bed by 10:45 PM. called in a Sereek Owl, which could be seen

From our campsite we can view Truchas Peak, approx. 13,815 ft. high, probably the highest point in New Mexico. The peak is above tree line, but only a relatively narrow bond. Along the roadway leading to our campsite, which follows Rio Quemado for all of the way, we observed Alder, Willows, Aspen, Yellow Pine, Douglas Fir, & Blue Spruce. The yellow pine disappears on the valley or canyon walls at about 9800 ft. At our campsite, the Douglas Fir, & aspen are the dominant tree species. Some 5-needled Western White Pine were seen. Where areas have been disturbed through clearing or burning, there is Aspen. There are beautiful mature groves, with trees over 50 ft. tall. (See photo 3/4). Along the streams, aspen & Alder are present. The Alder is a moderately sized tree, up to 25 ft. tall & 9 inches in diameter (the larger representative seen). By several times we could feel the effects of cold air drainage into our valley camp. By 8:15 P.M. temp. was 47° F. At sundown, saw several small bats flying over camp. O.T.

One Sorex sp. taken 2 ft. from stream at base of aspen. One Microtus sp. taken at base of alder in wet meadow. One chipmunk snapped at base of roll fence. From 6:50 AM to 9:30 AM. hiked along streamside & along crest of surrounding slopes, in a circumference around camp of about 2 miles. Observed the following: Steller Jay, Ruby-crowned Kinglet (107), Mt. Chickadees, Blue Warbler, Paleolated Warbler, Townsend Warbler, House Wren, Red-shafted Flicker, Raven, Clark's Nutcracker, 1 White-breasted Nuthatch, many gopher diggers, Chipmunk (numerous) Golden-mantled Ground Squirrel, Canada Jay. Warblers were most abundant in aspen groves & also noted in older thickets. Could not detect any pronounced N→S or down Mt. slope (E→W) migration. Chickadees were particularly abundant in one locality of Douglas Fir, where 3 were seen 'scolding' at one time. The following temperatures were obtained: Species Temp: Time Conditions House Wren 39.4°C 7:50 AM dead 15 sec. Townsend Warbler 40.5°C 8:25 AM dead 10 sec.

Bowman 1952 Journal. 39. Sept.4 6 mi. E. Truchas, 10,000 ft., Rio Arriba Co., New Mexico In the small valley immediately below camp there is a field of wheat. Some vegetables, radish & turnip are also cultivated. On the flat above camp there is a field of oats + a legume, & a field of potatoes. So far we have seen no sign of humans. At sundown (6:25 o'clock) we began seeing bats (presumably Myotis - one taken on Sept.3). They are fast fliers, frequently flying in a straight line. They are 'flocking' over an open valley area W of camp and over the stream to the south of camp, where alders & firs have been recently felled. Dr. O.P. Pearson shot 3, retrieved 2. The temperature is falling rapidly at this writing. The cold air forms a steady stream as it pours down the valley in which we are camped. Frost was detected on the ground this morning. Some of the aspens show a slight lightening in color. One one of the aspen covered slopes, observed a vigorous young growth of 10-15 ft. firs coming in under the aspen. Many of the aspen measure 20" across at their bases. Douglas Fir are about 1 1/2 feet across, although many of those cut in the area are rotten at the core. This are resembles the 11.5 miles NE of Choma composite, in that all the vegetation is lush. The undercover is much denser here, however and all the trees seem to be of larger stature. Some daisy, paintbrush, & clover are in bloom in the more shaded areas.

Pearson left our camp at about 10:30 AM today, with 2 sleeping bag, food & mouse trap, headed for Truchas Pk. He said he would report back to camp tomorrow noon. The weather has been clear warm all the time we have been here at our Truchas campsite. Some cumulus cloudiness has appeared yesterday & today, with just a few sprinkles of rain on a couple of occasions. This evening is our first touch of wind. Sept. 7 Temp. at 6:45 AM was 38°. This was the coldest night we have had so far. From 7:30 AM to 1:30 P.M. hiked along stream just north of our campsite, where a slight trail was apparent. --observed droppings of horse cows. Hiked to approximately the 11,500 ft. level (estimated) passing through the Canadian zone (D. fir & spruce) & well into the Hudsonian zone (fir-sp? & spruce). The dominant bird life in both concepts These zones was Junco, Nut. Chickadee, & a few golden- crowned Kinglets. Clark's Nutcracker was heard only in Hudsonian zone, but Chickadee we saw heard abundantly in both zones. In the highest elevations the soil was very gravelly & granitic. In the lowest Canadian zone near camp saw the following: 1 Red-tailed Hawk, 1 Cooper Hawk, & 1 Goshawk, Conceps Junco, 1 House Wren, 4 Pygmy Nuthatch, 1 White-breasted Nuthatch, 3 Steller Jays, Porcupine Scratching on a young yellow pine tree, 1 Broad-tailed Hummingbird.

Shot several Coniceps junco, which were in the middle of the molt. The brownish feathers on the shoulders & back were of two shades of brown, probably suggesting the old & new feathers were present. One junco was still an fledgling plumage, & the bill still showed obvious signs of immaturity, ie. yellow at the corners, & the 21000 barbed / hyprobound fly. bill did not have its adult shape. Bluebells & Indian paintbrush were in bloom at higher elevations. The alder, so common along riparian situations at our camp, disappears at about 200 feet above our camp elevation of 10,000 ft. Mt. Mehogany is quite abundant at higher elevations. The poplars (aspens) show obvious signs of changing color due to the cold weather at night time. The following temp- eratures were obtained: Species Temp. Time Conditions Coniceps Junco 42°C 9:20 AM. Dead 3 sec. " " 42.4°C 11:45 AM. Dead 10 sec. Many bats flying around camp this evening.

Commencing at 1:00 P.M. observed 3 "waves" of bird flocks moving through the pines. These flocks consist of Mt. Chickadees, Pygmy Nuthatches, Audubon Warblers and Brown Creepers. The direction of their movement was generally downhill along stream course compass. In the same area also observed Raven, Steller Jay, Red-tailed Hawk, Sparrow Hawk. Watched the Pygmy Nuthatches occasionally feed on the ground. The Brown Creepers were frequently quitied, and always would "work" on the opposite side of the tree to where I was located. The birds were difficult to located on the tree, and even though fired at once (amiss) they would remain on the same tree, apparently little disturbed. Saw atleast 5 Creepers. The Pileolotes Warblers were always to be found singly in the low scrubby Gambel oak, and were rather difficult to approach. The following temperatures were taken during the day: Species Temp Time Conditions Coniceps Junco* 41.8° C 8:15 AM alive Ruby-crowned Knight** 39.5° C 8:25 AM alive Brown Creeper 41.6°C 1:45 PM dead 15 sec. * Junco was imm. + molting.

Strong SE wind blowing this evening . Saw a flock of 17 terns(?) flying southward along river, "bucking" this head wind. For this reason, I am not certain these birds were not nighthawks. It was too dark & birds were too high up. Nighthawks were flying very close to the ground, apparently because of the strong winds. One Cooper Hawk seen overhead at dusk as well as a flock of small ducks (9), possibly Teal. After dark Stuart Lordy and I captured approx 7 Rena (2 sp.) in mud-hole (photo 4/14) using flashlight, shin-boots (for mud). Boot-eye shine from both species. Saw a 3 ft long garter snake in the water. Many small jumping fish (sp?) in some water (mud) hole. Slight eye-shine from snake. Because of wind, no owl calling tonight.
