The red-eyed Flycatcher (_V. olivaceus_) is the most numerous, and not only is constantly to be met with in the woods, but ventures confidently into the public squares or parks, and the yards and gardens of the cities. In many such localities in Philadelphia, several of which are in the denser parts of the city, this little warbler rears its young, and pipes out his sprightly song, in entire security, and apparently feeling himself as much at home as if in the recesses of the most remote forest. The warbling Flycatcher (_V. gilvus_) is another pleasing singer, though in our opinion but an indifferent performer compared with the preceding. A species common in the West Indies, and which has been found in Florida, has some very singular notes, from one combination of which he has had assigned to him a name quite as singular, the “Whip Tom Kelly” (_V. altiloquus_). The immediate relatives, however, of the little species before the reader in the present plate, are birds that rarely venture far from the woods. One of them, the White-eyed Flycatcher (_V. noveboracensis_), has a partiality for marshes and low grounds producing thick growths of vines and shrubbery; and although the smallest of his tribe has some quite remarkable notes, and so loud, that a person not sufficiently acquainted with him to recognise his voice, would be surprised to find such a high-sounding solo proceed from such a diminutive performer. The species represented in our present plate is an inhabitant of Texas, but it has as yet been only observed in a very limited district. It was discovered by S. W. Woodhouse, M. D., of Philadelphia, while attached to Capt. Sitgreave’s Surveying party. It is the handsomest bird of this group. The following notice of this bird by Dr. Woodhouse, we take the liberty of extracting from Sitgreave’s report of an expedition down the Zuñi and Colorado rivers: “On the twenty-sixth of May, 1851, while encamped on the Rio San Pedro, within about ten miles of its source, I was out in pursuit of specimens. Wandering about the hills among some cedars (_Juniperus_), my attention was first attracted by a singular note, which I am unable to describe; on looking, I discovered this beautiful little bird, which I at first took to belong to that interesting family of fly-catching warblers, _Sylvania_, it being constantly in motion. It was with the greatest difficulty that I could procure specimens; two, however, I secured, both of which, on dissection, proved to be males.” Mr. John H. Clark, zoologist attached to the Mexican boundary commission, who observed this species in Texas, and near the same locality at which it was found by Dr. Woodhouse, has very obligingly made for us the following note from his journal:
