L Pearson 1969 Journal Papa Leon Trece, 150 ft., Depto. de Lima, Peru June 1969 Mynal and I arrived in Lima about noon, joined AK + Ray Hilbarn, OP Pearson, and Mrs. Davis + kids, and drove south through sand hills along the coast to Papa Leon Trece, a "housing development" a la Peruviana near Pucusana. On the drive down we saw several vultures (flaco?) flying and pelicans, and dark grey gulls and some grey + white gulls sitting on the beach. Also a vermilion flycatcher on a phone wire. The only water hereabouts comes up from wells. Ray, Mynal, + I went to some hills 4 kilometers drive east NE of Pucusana and set traps. The hills are steep and rocky, and in the gullies + washes and on the tops of the hills (where the fog is closer) some type of cactus grows, of this form: [drawing]. Most of it seems dead, + you have to look close to see that some branches are green + fleshy. I found two small cactus, maybe the same kind, with long red flowers with yellow inner parts. Cactus is the conspicuous plant, but lichens are more ubiquitous, all over the dusty ground, the rocks, + the cactus. Up at the top of the hill I climbed there were with clover-shaped leaves occasional clover plants + some lily-family plants. (The sky was continually foggy + seemed to come in closer as it got later (5:30 ish) and a bit breezy, but it wasn't cold.) The hills because of the dry + still weather and tracks stay around a long time, + people tracks + paths were all over, + there were trails crisscrossing the

Carol Pearson 1969 Journal Papa León Tree 2 July I saw 1 or 2 burrowing owls + then the garrus came on thick, so I saw no more. In driving through irrigated parts we saw lots of mockingbirds, + over one dump we saw a turkey vulture. In town we see blue+white swallows, zonotrichia, and a gray gull (Larus modestus) 3 July 6:30-7:30 again up the valley at 8 km east N& Pearson fog usually too thick # close to see up the hills where some birds were calling. The route out croppings up the hill have great mounds of some bromeliad on them. Rest of morning spent at 5½ km NE San Bartolo, where we caught made in the traps on the rocky slope and moved the traps across the river & valley to the sandy hills. I set 40 #ge collapsible Shermans roughly 35' apart in the sandy Tillandsia but near to rocks of the top of the ridge in places. Oatmeal bait. Birds!: A pair of miners on the sandy Tillandsia hill. They caught my attention with twitters + calls notes as they flew over the ridge and down to the river gully. There they spent time around the mouth of a burrow under a rock sticking out of the river bank of the gully. One went in it once, + there might have been young bird noises. One sat at the mouth about a few minute or so. Otherwise they didn't seem to be doing anything definite except preening sometimes. When I went near the burrow they come near + continued their calling. They cock their tail & run on the ground. The mouth of the burrow was not distinctive, didn't

Carol Pearson 1569 Journal 3 July Papa Leon Tree look like excavation, but there was some soft, fuzzy material at the mouth. The mouth was just the wide area under the overhang of the rock, + the burrow went back from this. The bird itself was pretty darn plain, breast light grayish with maybe a central speckle, back darker + brownish, sides pinkish or pale rusty. I'll need a better look. No white in wings or tail when it flew, but perhaps lighter outer tail feathers. Perhaps Geositta maritima. A quite large hawk flew over watching me and then landed on a sandy hill for awhile. All dark above, chest + beginning of belly light tan with some speckles. Molting some primaries. I don't think it has the shape of beranoactus. While it was on the ground, standing, it looked huge too, + showed whitish above the shoulder, bird facing around the front of his neck. In the afternoon 2-3:30 we went further up the valley behind Papa Leon to a place 10 km. east NE Pucusana, 250 m. Here is more rocky, steep hills, all lichen covered, more lilies + other plants but not cactus. At the a burrow of 2 owls were 4 pellets, 2 entirely of black beetle parts, 1 for 2 with a couple scorpions and parts of 2 mice. The burrow was shallow + only about a foot deep in the soil and didn't look very used. There was lichen growing all around it, as elsewhere, + a rock in the mouth of the burrow. Here I saw a pair of perhaps miners - they'd fly from one slope to another. Also heard a strange w-wwr! w-wurr!

SW Casapalca, 13,300 ft. had one Phyllotis andinus (#4 CP), caught along a large rock with both bushes and Stipa nearby. He was still alive after what was a really cold night for us. The comps at 2 mi E N. Casapalca, 14,400 ft (near a train station labelled Chinchon) is in altiplano zone - all grasses + a few low bushes + a low cactus. A small river runs down the valley + side streams join it. Rocks plentiful. In a couple hours birdwatching in The middle of the day I saw some thigs I could identify using Koepcke: Falco femoralis - one lge falcon with buffy heeadstipes, all gray back. Muscicariola alpina - 10 - slender, upright; run on ground or sit on rocks; dark gray [illegible] crown + mapes; lighter area in front of eye, perhaps some dark behind eye; pale gray underside; gray back; [illegible] gray-brown wings; dark gray tail with light outer web sometimes seen. Upucerthia valdivioris - 5 - long, down curved beak; pale brown, darker above. Thus very fast on ground, hammers ground with bill.

Carol Pearson 1969 Journal July 10 Papa Leon Trace Mid-afternoon we went up the valley, where the lilies were still going, but beginning to fade, (8 pm ENE Pucasona). The fog was lifted so we could see even to the tops of the hills. Saw Condor (1), Pygocelidon & cyanoleuca (10). Also 3 Vulture Geositta peruviana maritima : med-sized; runs for almost hops continuously on ground + poor rocks, occasionally slightly cocking tail ; attention directed groundward, hunched a little forward; onceasionally catches fly with a flutter; plain grayish brown back, blackish tail, dusky undersides white, on throat, faint cyeline. Heard a song like a house worn. July 11 Spent most of morning tromping around Tillandsia desert & mi SE Chilea, looking under plants and digging in holes. I found about 4 or 5 kinds of spiders, 3 scorpions, silverfish, a very small cricket, an insect like a velvet ant sort of - all these under plants. I didn't notice any pattern of distribution, + all spiders about equally common except one very large one that got away + lived in a hole about 1 1/2" diam. On a sort of the desert that has dirtier soil with a crust on it there were holes like at Quebrada Cru de Hueso, + in one of these I found a gecko. Early afternoon we went up the valley to 8 km ENE Pucasona, + I climbed up the ridge there that has cima vegetation on top (some hills are just cactus). On the high slopes + top of this ridge were lots of lilies among the rocks, a bromeliad, mostly dead masses, on the outcroppings, a few small + gnarled trees with broad leaves, one

Carl Pearson 1969 Journal Papa Leon Tree 11 July every legume type tree, + a few bushes. It was a day of high, light fog, so I could see the ocean + lots of hills, + it was warm. I saw no signs of mammals except small diggings, skunk-like, at some bulbs. I found a dead + a live tarantula-like spider living in [crossed out: crosses] holes or burrows. Also a small (1 1/2 ft) snake, slender, brownish black with 2 dull yellow stripes. Up on the rocky cliffs was a Geositta with rufus in its wings; it fluttered its wings while making its loud, chattering noise. It also makes a strange "wa, wa" call. In a tree clump at the very top of the ridge were a pair of Zonotrichia capensis and a pair of Troglodytes aedon, with the [illegible] wren singing just like at home. There was another wren singing in the next valley over the ridge. The wren seemed much trufly [crossed out: darker] tender on the abdomen than I remember wrens in VST being. Also saw a Condor and a slew of blue + white swallows and the other Geositta probably maritima, and 2 burrowing owls. Late afternoon we spent on the study plot again. We to saw a lizard, probably like the one I caught this morning off the plot on a hill with bluish rocks. That one this morning lost into a Tillandsia when I came along. I started mopping the piles of bird droppings, each dropping a coil or squiggle of greenish thread about 1/8" thick. The whole droppings about 3/4 - 3/4 " wide, sometimes with white on top. They occur in piles of maybe 10 or more. AKR [crossed out: ?] OPP, and I

Carl Pearson 1969 Journal 14 July + dead parts, + shake vigorously over newspaper; quickly pour through fine screen into pans (2); search with eyeballs through sand in pans and stuff left on screen. This turned up stuff, but not all plants brought the sand below them with them. Afternoon technique: shake a plant-mat in place, lift quickly, drop KIM can (12.7 cm diam) upside down + push in about 1/2", slide something (like notebook cover) under can, pick it up, dump in bucket, pour small portions in pans to search with eyeballs. We tested to see if bichos got squashed or lost when poured with sand by catching live collembolos, mites, insect A, spiders, putting them live in the bucket, dumping in some sand, + searching in pans. We found them again. The KIM can method seems to work, just doesn't catch much because of small area covered. We found a baby gecko under a Tillandsia; he was about 2" long, + a small white, fragile eggshell was under the same mat. We found 3 other such egg remains during the day. Also found 2 large scorpions in the > flowers like grew course of the day. A large weevil w snout sunk into a shoot of Tillandsia. In Papa Leon I watched a hummer sit in the (1:10pm-1:50pm) fig tree out back for 40 min without changing perch. He turned his head from side to side jerkily about 2x/sec. The whole time. Two other hummers were in the tree at various times during this 40 min. When he left, he zoomed off among the Casuarina, catching insects 3, ignoring the

Ducks on small pond: slender neck, white check+ fronty Throat, black? top of head + back of neck, dark under tail, tail lights, slightly from above in flight. Anas versicolor or bahamensis Night - returned to study area, walked around lake side but saw nada. hunted spiders + geckos on plot, found some + one respectively. Heard bats + crickets. A large orb-weaver on his web. 16 July Drove up to havana Pachacamac to pick up Jorge Reyes and his friend Andres Mendoza, who guided us up a valley south of Lurin (going just satellite tracking station) to location 20 km E Lurin, 1000 ft. This is a very rocky + steep-sided canyon, this year fairly lushy with lilies + other herbs so that people with cattle, sheep, & goats + accompanying dogs had moved in. So no vizaachas, which had been promised, of course. Flocks of Sicalis started exploded + zoomed along the valley with loud chattering + settled on the cliffs, like insects or bats. Ones I saw were plainish brown, some with yellow wash in front. Maybe 500 of them. A hummingbird whizzed by. Geositta maritima spread evenly all over. Pair Troglodytes musculus. 20 utulbia copensis singing, a few in valley, a couple up side canyons, dif song than at Populoon. Cathartes aura - one The valley got dry + barren again as we went further; the fog got stuck on cooler more western peaks.

Carl Pearson 1769 Journal 19 July hopped, walked for maybe 1 min., then zoomed off toward fields. Then a flock of 7 small doves flew north toward fields. Before those, while still light, a hawk flew over. Did some small with counts (13-16). 13 was a dif. technique: shake plant on canvas + into + pour into bucket, then search small portions on canvas + in pans. This plant had a drift of sand over part of it. It was a cool + slightly breezy morning. Cleared for middle of day. Walked along beach just north of Puerto Viejo. Picked up old porpoise skull (CP 14), cormorant skulls (CP 11,12,13), procellariiform skulls (CP 8,9,10), a fairly complete skeleton of small procellariiform? (CP 13). 10: small, white below, black spots on white all over back, black band on end of tail. Also picked up 3 eggs we found on beach while up + were being drifted over with sand. These turned out to have chicks in them, not rotten, but dead. The chicks had 3 unwebbed toes. On the pond at the north and of the beach were Tringa flavipes (7), Charadrius vociferous (4), Anas bahamensis (7), Charadrius alexandrinus (6), some sandpipers like western. On beach were usual plus 2 black oystercatcher. To Pochocomac in midday. Coctus hills late pm. 5 mi & Yungos, 9,000 ft., Dept. hira, Peru 20 July Left Puya León early, drove 5 to Cañete, had fun at the mercado, drove up towards Yungos but stopped for night before we got there. A really beautiful canyon with lots of almost turquoise water + neat irrigated fields

Loral Pearson 1969 Journal 5 Jul E 10 am's Yanap, 8,000ft, Deshina 20 July along it, sunny, pleasant temp. Saw about 8 condors, lots of doves of various sorts that I don't have sorted out yet; & vencejo andino, Pygchelidon cyaneaea, a fluke of small green parrots, 2 large parrots, 2 woodpeckers, lots of mockingbirds, several long-tails) blade birds (but anis), a ? torrent duck, several [illegible] Tyranus [illegible]. The hills above irrigation line were quite bare + rocky (yellowish rocks) for the longest time, and then shutly before where we stopped ceotus + Tilloukia's came in, + than shutly before we stopped, bushes. Here now the river are Scotch broom + other brushes, fig trees + others. On the slopes are some kind(s) of columns - bushy coetuses, picklepear in places, dead-looking + everydry bushes, agaves, + even a bit of tall grass, dry. I set 26 lge folding shamans with oatmeal + 7 snaps w oatmeal across a brushy slope with little rocky cover + than up a rocky slide where there was more agave + lge cactus +, up high some grass (tall +dry). Windy afternoon, but still evening. 21 July Wind down the conyon most of night, morning. In my traps: live - 1 Phylletis andium snap: 3 P. annius ( OPP identified). The snaps were at stations with live traps too, toward the end of the line where there was more rocks + lge cactus + agave. One live trap had us beat in it + had mouse droppings in it. I had found one place with a small pile of dry grass. Set up two mist nets (Blitz), one between shore

(N2) Thrushes were singing in am; 4 large parrots flew by. 9:30am - caught Elaenia in N2. Nets up all day. Sunny + windy all day, wind changing from down to up valley about 2pm. During day saw: Condor (2), sparrow-hawk (2), Cercomacra (1), Apus andecolus (3), sooty bellied swallow (2), Myiophobus fasciatus (1), Myiotheres tuberculifer (1), paroto (4), Batis diex (10), Tundea chiguano (10), Cinclus leucopehelus (1), Columba maculata (2), small hummingbird (1). I set traps in big bushes along road, both sides: 15 small shrews or oatmeal for birds, 7 snares at stations w/ 7 large folding shrews w/oatmeal. Saw a bunch of these Turdeas hopping on a turfey place by river, just like I migratory. Cinclus was a disappointment - hardly bobbed at all, didn't go under water, just jumped from rock to rock, getting his feet wet, eating from algae-covered rocks. 22 July Caught nothing. About 9am got a Patagona gecko in N1. Watched 2 diggers in river in front of camp. They were both blotchy brown, + the white on their heads was sort of grayish. Could they be molting, + that's why they don't go underwater? The deepest one got was in up to his belly. A pair of torrent ducks went by camp too. The 4 graced. They could have beat us down the Rio Corite. We descended + found we hadn't been where we thought we were, that to get to Yungay you have to turn up the mountain at a town called Magdalena.

Carol Pearson 1965 Journal 25 July Papa Leon Trace / Pomacocha, Yauli Valley, 14,212ft, Dept Junior, Peru Stopped at Hacienda San Andres + walked up to a Tillandsia sign, B16, made in 1946 according to Cheerful Charlie. Two dark blotchy buteos flew over, + there was a dead barn owl in the orchard. 26 July Up The Prince, over the pass (Anticona, 4843m = 15,806ft), down past Laguna Ducto, where we (Pleuge, Davis, me) saw Lonchoretta specularoides (2+), Anas flavirostris (30), Anas georgica (2+), Chloephaga melanoptera (1), Oxynura ferreirae (5), Ptiloscylus resplendens (2), Larsonia rufa (1 wading in water). The Anas were puddling on mud bars, the goose was just standing about. There were good snow-covered peaks around there. Then down through yellow-grass-covered valleys + more colorful mts to Pomacocha, Pleuge's Rod + Gun Club. This is on a false lake near Yauli, 14,212 ft., with lots of stipa and rocks. About 4:30 I set 14 Mus. Specials and 10 West German Raptids with cheese, through Stipa + rocks. Some birds we saw: Muscisaxicola alpinia, M. w rusty caps, Cinclodes fuscus to atacamonis, Ochetorhynchus persimulans, Phrygilus gorgi, Phrygilus plebejus, Catamania minorata? (all gray w yellow-orange bill) (white undertail, brownish streaking back, fine streaks on crown, faint eyeline), Zonotrichia capensis (not singing), Oreotrochilus (landing on ground + flying out to catch flies; blue green tail w white tips, blotchy yellowish back, rusty forehead , rest wings green), Colaptes rupicola, Asthenes i humilis?, Upucerthia sp., + mystery birds. 27 July Caught 3 Alcodon in Mus. Spec., one very small so I didn't put it up. Across the lake in a small talus slope we saw a muscacha, where Ray had shot one yesterday. Also saw Agriornis montana as well as some things from yesterday.

Lord Pearson 1969 Journal Pomacocha, Yauli Valley, 1432 ft., best June. 27 July Davis & Plenge shot 3 species of Asthenes. Nornish left for La Oroya, where RH, ML, + I got in a collective + went to Huancayo. Huancayo is in a long, fairly wide + flat valley with lots of planted Eucalyptus + Juniper trees. Lots of grain + cattle + sheep. Dusty mountains in pastel colors. Pastel orange-red tile roofs. Doves, Sparrow-hawk. On the river in La Oroya @ Mantaro, were some gulls with black heads. Touristed in Huancayo. 28 July Took train down to Lima for $90 segunda clase. Having a good garúa here. 29 July Papa León Trees Early morning went to study area and collected water from in the base of Tillandsia leaves.
