155 Oct. 1932 Castle Ck. R.S., S Fork Clearwater Ck., 1800 ft. Idaho Co, Idaho. July 16, 1932: Growth of Douglas Fir on the canyon bottom and on the N-facing slope, with Yellow Pine growing on the more open upper portions of the S-facing slope of the canyon. Chestnut-backed, Black-capped, and Mountain Chickadees are all to be found here, as are the three kinds of Nut- hatchies, Slender-Billed, Red-breasted and Pigeon. Willow Thrushes seem as abundant as Olive-backed Thrushes. Blanchard found an Olive-backed Thrush's nest with one egg in it today. Placed out 55 mouse and 10 rat traps. Mouse traps placed among the ferns and in the Douglas Fir area. The rat traps were placed on stumps, and nailed to trees. A Horned Owl was heard this evening. July 17, 1932. The trap line contained only five Corvuscaus manci- culatus. Shot a Chipmunk and a Flycatcher which appears to be E. hammondii. These flycatchers are abundant among the ferns and have a call note dif- ferring quite a bit from that of a Wright. Likewise they have a series of small notes unlike those of the Wright. A Red-eyed Vireo was seen down among some cottonwoods along the river. I shot a Chestnut-backed Chickadee early this p.m. Heat came in response to a Pigeon Owl note given by Miller. He shot one of these Pigeon Owls this a.m.- At 4:30 p.m. I shot 2 more Belted and a very large adult Lilies Columbianus.
