R.K. Selander, 1953 Oct. 5 Zapotal, 1850 ft., 3 mi. S Tuxtla Mutieng, Chiapas Mex. The N. leucalis flew from a perch high in a dead tree and caught a large insect in the air, then returned to its perch. No calls heard. Heard several chachalacas calling high on the hill. Greatcatchers (tap?) common, Turdus grayi common. The vegetation immediately surrounding Tuxtla is deciduous for the most part, with a mesquite-like tree occurring very commonly. At about 75-100 feet above Tuxtla to the south and just above the settlement called Zapotal many ever-green trees and shrubs appear, including fig, and mango. There are several palms near Zapotal, including a few coconut palms. The forest on the crest of the "mountain" south of Zapotal is not totally composed of evergreen species, however, since a number of the shrubs and small trees are deciduous. It is predominantly evergreen nevertheless. Birds either absent or under cover because of the wet weather in the thicker portions of the forest, since few were seen. No green jays noticed. May have heard C. zonatus near highest point we reached today but cannot be sure. Alvarez says Chordeiles minor occurs on the flat mesa on top of the hill above Zapotal and that "you should be able to collect 10 specimens easily," a region of scrub patches & grass.
