Orr 1932 Glidden Lakes, 5700 ft., Shoshone Co., Idaho. July 24, 1932 giving a call consisting of 3 similar notes. Further up the slope I came to some very slides. At 10:30 p.m. the animals were not very active although they could be heard calling below the rocks. I managed to break up a number, shooting three. One of them was a young individual about 1/3 grown. I went around the ridge and came to a small alpine valley just beneath a snow-covered ridge. Crows were to be heard everywhere in the lake slopes that surrounded the valley. I saw three other very young ones running about the rocks. One was seen to give a call just like the adults, only not quite so loud and slightly higher. This small valley was rather lacking in timber, but contained a few small firs. Eleven young junos were seen in three flocks consisting of 4, 3 and 3. Shot 2 which appeared like adult &'s at a short distance, but proved to be young which were molting. Mountain Bluebirds, House Lories, Clarke Water-lickers, Chipping Sparrows and Flickers were the only birds noted here. Captured two more Pava this a.m. Inspected an Olive-backed Thrush's nest which I found last p.m. It had 2 young just beginning to show pin feathers along the main body tracts. The nest was in a small fir along the creek, 2 feet above the ground.
