Murray 1948 Journal July 6 10 mi SE Mesquital, 400+ ft., Baja Calif. Saw three black-throated gray warblers, and finally identified another woodpecker as the ladder-backed woodpecker. This is fairly common among the yucca which it seems to prefer to work on, while the gila woodpecker is almost always in the wash with cardons. Saw another Sceloporus magister which promptly rushed into a woodrat nest. Quite late in the wash there were two nighthawks Set 50 live traps, part along the road and part down the center of one of the open places with only small shrubs. In the evening well after dark, a Phyllorhynchus decurtatus leisurely crawled up to within a foot of the camp fire and not far from where I was sitting. Took its capture rather calmly. July 7 Same location Traps caught 1♂ Perognathus baileyi ; 1♀, and 3♀ released, Dipodomys merriami; 2♀, and 2♂, 2♀ released Dipodomys agilis, 1♂, 1 other Perognathus arenarius, both released. (See sp. acts.) The open ground had a little better percentage of catch, and had the arenarius. The baileyi was in the brush.
