“This bird was first seen at Charco Escondido, in Tamaulipas, on the tenth of March. The male had evidently preceded the female in his arrival, as the latter was not observed until several weeks afterwards. Early in the morning, and again about sunset, he came to the artificial lake that is constructed here for the supplying of water to the inhabitants, and appeared to be of a very quiet and inoffensive disposition, usually sitting on the upper branches of the trees, occasionally uttering a low chirp. Subsequently, it was met with in Nueva Leon, though I had little opportunity of observing its habits. It appeared, however, to be in some respects similar in its manners to the smaller species of the Northern Flycatchers.” Dr. Henry has also met with the present bird in the vicinity of Fort Webster, New Mexico. He represents it, however, as of exceedingly rare occurrence, so far as he has observed, and fully confirms the statements given above, respecting its partiality for the neighborhood of water. His first specimen, a male in full plumage, was obtained on the Rio Miembres, near Fort Webster, in the month of March, 1853. DESCRIPTION AND TECHNICAL OBSERVATIONS. Genus Pyrocephalus. Gould, Zool.
