Cogswell 1950 Asio otus (wilsonianus) June 25 4950 ft. 2 mi. W Vinton, Plumas Co., Calif.- 1 dead on road near 2+ acre patch of short willow trees along drainage in a broad grassy valley. The carcass was already infested with maggots so I did not save it. July 31 Sugar Bowl Lodge, 7000 ft., 1.2 mi. SSW Donner Pass, Placer Co., Calif.- 1 found in dense area of red fir, silver pine, lodgepole pine forest just N. of lodge; it was being scolded by a mob of small birds, including 2+ Bobus (whose calls first attracted me to it), some Junicos, chickadees, Audubon warblers, etc. The owl was seen both while perched and in flight. This is almost the identical spot where one was seen in 1948 (July 22, Aug.6), the whole surrounding area being of coniferous close forest with cleared or meadow areas quite Aug.10 I seen in same area under like conditions. Aug.11 “ “ “ “ “ “ Aug.16 Mrs. B. Nielsen, while visiting camp today, found the owl perched quietly about 45 ft. up in a 60+ ft. lodgepole pine amid close growing group of same. Some 40 or 50 people turned out to see the bird, which just sat on the limb next to the trunk looking down at us. no small birds scolding it. 4 pellets found nearby were of size indicating this bird. I collected them (uncatalogued) for possible later study.
