Marshall, 1942 Coragyps atratus December 25-Jan. 16 Mt. Cacagnatine abundant - in groups or loose flocks, especially around habitations. In midday perch in groups on dead snags, hold out wings in sun. at night - scoot in finca - lots of missing & flapping around even after dark. Often seen on ground around houses. Also on trails & roads in finca where, when approached, they lope away with a curious awkward gallop to jump hard with one foot [illegible] than the other. They scan with wings held out straighter than Cathartes & often with feet dangling. The 2 sp. don't associate closely at all. Jan. 22-Feb 24 Lake Olomega abundant, especially around flat country around lake - came immediately to carcasses put out around camp. Common at Santa Clulata.
