R.K. Selander, 1954 16 mi. SE San Cristobal, 7200 ft., Chiapas, Mexico April 19 other insects. The gizzards of the nestlings seemed full from the manner in which they protruded. Found a pair of Troglodytes musculus on a gentle hillside near the highway. These birds were frequenting a pile of small branches and dry herbs. I saw them on the ground where they looked like small mice running along. On occasion they moved up to the top of a small tree stump. I collected one of these in the spot where I found the Caprimulgus nest. Noted a large red-bellied trogon in oak woods near the tent. Also collected an Oriole - [illegible]? thi the common oriole seen yesterday feeding n trees is similar fashion to the cactus wrens. The common wrenble here is D. virere, one of which I shot for identification. Took a Leptodocola affines - one of a pair on small oaks near the tent. Also collected three C. zonatus near camp. Generally speaking, birds are uncommon in this area. The Turdus rufitorques is one of the commonest birds seen and the Aphelocoma is abundant also. The Dendroica virere occurs in huge flocks, along with several other small birds, including, I think, a Virio sp. Today was clear except for a cloudy period in late afternoon. At 8:30 P.M. it is slightly cold.
