1 mi. E of Omitéme, 7400 ft, Guerrero, Mex. July 22, 1946 Hunted from 7:15 a.m. to 11:30 a.m. Heard P. orai in a swale a short distance west of camp, but could not locate them. Then took a road that rose about 200 ft. and led into a path that followed a ridge-top. Vegetation along the ridge top was primarily pines, with a few oaks, and an understory of maguay, shubs, and small palms. The ridge was quite narrow and dropped off sharply on both sides. There were numerous rocks, both on the ridge top and the adjacent slopes. No P. orai were heard above the swale at the foot of the ridge. Saw several of the oriols I had noted yesterday, but they were very wary and I could not collect one. Their song is a very distinctive, broken series of pure, whistled notes, varying in pitch -- ^ ^ ^. They utter a harsh, jay-like note when alarmed. While pursuing an oriole, I flushed 2 large owls from the top of a pine tree. They separated and flew to adjacent pines, a few yards away. One was taken, & proved to be Strix varia (sartorii?). A q Vigourous mexicanus was taken from an oak. Attention was attracted to it by the hooting notes it gave: - cub-cub, cub-cub- cub-cub-cub. Several Western Bluebirds were seen, and 1 Hiranga (flava?). California Wool
