Hoffmeister 1942 Itinerary May 16 Walker Cr., 4 mi. SW Olancha, Inyo Co., Calif. tree to see the birds, only 1 remained. Also a shrike (Lanius ludovicianus) flew in across the Artemesia flat and perched in the top of an oak along Walker Cr. I was unable to collect it however. At 9:00 a.m. there were about 35+ White-throated Swifts flying over the Artemesia flat. At 4:00 p.m., I heard a Red-shafted Flicker a short distance from camp. The California Jay was shot near camp when it perched in an oak along Walker Creek. Two bats were seen around camp at about 8:30 p.m. Also at 8:30 p.m. (war time; 7:30 p.m. standard time), a Peromyscus boylii was caught in a trap beneath an oak in camp. May 17 Set 50 traps twenty paces apart down the Artemesia flat toward Olancha, from the junction of Falls and Walker Creeks. Placed the traps in openings between bushes with the hopes of catching heteromyids. Caught 29 Peromyscus maniculatus (15?, 14?). 24 traps set in the Artemesia, Chrysothamnus, and Lupinus association paralleling Walker Creek caught 3 Peromyscus maniculatus and 1 Cnemidophorus tesselatus. 5 traps in the willows along Walker Cr. cought 4 P. boylii and 1 P. maniculatus + 2 traps in camp caught 2 P. boylii. Returning from my trap line, I shot a lactating ? Cettulus beckyi. Four young were on the same rock with the adult ?, and I assume they were a part of her litter. The four young were about the size of a Eutamias townsendii. I saw 5 Lanius ludovicianus, shooting 1. One shrike flew off with one of my cotton trap markers when I was going over my trap-line. Evidently this bird was nest building. Two birds were seen chasing other shrikes. Two Stellar Jays were seen, 1 California Jay, 1 Rock Wren, numerous Black-throated Sparrows. The White-throated Swifts flew
