152 Orn 1932 Alturas Lake, 7000 ft., Blaine Co., Idaho. July 12, 1932 Found the following in the traps: 2 Zapus princeps, 1 Sorex vagrans, 4 Microtus ordax (1 juv.) and 1 Microtes. The two Zapus were a σ & ♀ taken within 15 feet of each other. Spent entire day skinning both previous and the days material. This p.m. I placed out 65 mouse and 4 rat traps in swampy area across the river and beneath the firs. 2 Horned Owls and a Poor-will heard. July 13, 1932 Last evening I heard a number of young Junco's calling from a nest beneath a Yellow Birch from which Miller shot a ? yesterday a.m. This a.m. the nest contained three dead young birds just beginning to get feathers along the tracts. They were preserved under Miller's catalogue collecting number. The nest itself was in the ground and covered over by stones from a grass clump. Found a Lincoln Sparrow nest near this. It was on the ground in some tall grass beneath a small willow. The nest was composed of small stems of dry grass. There were 3 eggs and two young just hatched in the nest. The parent ran off in the grass, reminding one of a meadow mouse. It was not seen until about 50 feet away then it flew up on a Small willow and began to 'chip'. It was heard to give the 'thumping' note once or twice later. The traps contained 2 Microtus , and 2 Ceromyces
