Transcribing the field notes of the Museum of Vertebrate Zoology

Heard "pe-ark" notes of Nighthawk last evening. A Green-backed Goldfinch flew over camp. Heard a Cooper Hawk calling near camp. Blue-fronted Jays are much more in evidence now than a month ago - noisier. A circuit this evening, till dusk, down along the willows and tracts of lodgepole pines left an impression of extreme quietness; nothing was singing. Juncos in two places showed worry, as if young were near by. The squeal notes of young robins were heard. A lone Wright Flycatcher gave a two-syllabled "see-pit" a few times.

July 29 Mrs. G and I went up the Viola (Martin Cr. ridge) Trail to about the 5800. foot contour, taking the accompanying 4-hour census, 8:30 - 12:30; Mrs. G. pencil-checked on card-board; results, 31 species, 134 individuals, in 4 hours - not so bad, considering the songlessness [sic] of nearly all species. The only songs heard were: Fox Sparrow (once); Warbling Vireo (2, singing rather persistently); Mountain Chickadee (both "jumbling" burble and tee-tee, too-too); Cassin Purple Finch (merely fragmentary). Only food calls, or location notes, or clean calls of all other species heard. A brood of 3 bob-tailed frowsy-headed young Tolmie Warblers in ceanothus cordulatus patch, with [female symbol] parent. Saw where a Chickaree was working in a yellow pine - ground beneath strewn with fresh green cone scales and cores; heard at least 4 chickarees.
