Oct 1931 East slope of Lesh Mtn., Lincoln Co., Nevada June 8, 1931 2 Peromyscus truei, 4 Peromyscus maniculatus, and 1 Perognathus parvus. The truei were found higher in the canyons, and usually near rocks among the piñons. P. parvus was trapped in the sagebrush on the slope of a hill. Sectanias dorsalis is very abundant among the Piñons, particularly where it is rocky. Shot a Black-throated Grey Warbler. Saw another foraging on Piñon Pine branches. It caught a caterpillar and flew off to another tree, indicating that it had a nest there. This act was noted again. Saw a pair of Lead-colored Bush-Tits calling quite merrily in a tree where I was standing. One carried an insect in its mouth, also possibly indicating that the pair had young. They would not go to the nest when I was in the vicinity. Audubon Warblers and Bewick’s Sparrows are quite abundant, the former being found higher up on the slopes. The Bewick’s Sparrows are usually seen in threes or fours, keeping close to the brush. Many Broad-tailed Hummingbirds
