1 mi. E of Omiltene, 7400 ft, Guerrero, Mex. July 21, 1946 and in the swales at the foot of the slopes. Went hunting and took 1 Pipilo ocai, 1 Sepidocolaptes affinis, and 1 Cyanocitta stelleri, all from oaks near camp. The P. ocai give the same high-pitched "beeeee" note as the P.o. brunescens we collec- ted in Oaxaca. Ran into 2 more groups of these birds but was unable to find them in the under- brush. Steller Jays are abundant and very im- wary. California Woodpeckers are abundant in the oaks. Saw 4 Allied Woodhewers, one group of 3, and a solitary bird hutching upon oak woodpecker fashion. This latter bird was collected. 2 Troganmus mexicanus were seen in the oaks. One was uttering a series of low toots. One very flashy cadmium yellow black Oriole was seen. Noted 1 Siphaga picta feeding on insects(?) which it was gleaning from the face of a large cliff. Troglodytes brunnicollis is abundant here, and numbers of them fly from the brush in response to squeaks. Several Sitta carolinensis and Brown Creepers were noted foraging through the oaks. After dark I took a walk down the road, and heard a tremendous Hyla chorus. At least 6 different notes could be made out. The oaks here support a fair Proeliaid growth and there may be Odipus present.
