Sylvia sphagnosa, Bonap.
PLATE CXLVIII. Male and Female.

I have met with this homely and humble little Warbler, on the low, almost submersed Keys of the Floridas, about Key West, in considerable numbers. This happened in the month of April. One was caught in a house at Indian Key some days before. In a short time, however, they all disappeared. Like many other species of this extensive and interesting family, they seem to cross directly from Cape Florida to Cape Hatteras, as none were seen in Louisiana, Georgia, or the lower parts of the Carolinas. It is not improbable that it comes from the West Indies, resting a few days on the lower islets of Florida, before proceeding northward. In the early part of May, I have found it in New Jersey, as well as in Pennsylvania, particularly in the Great Pine Forest, where I drew a pair of them, and found their nest. During my progress eastward, I saw them frequently. In the State of Maine, I found them exceedingly abundant near Eastport, and on the other islands in that vicinity; but there their progress appeared to have stopped, for I did not see one of them beyond the Island of Grand Manan, while on my way to Labrador.

The Pine-Swamp Warbler delights in the dark, humid parts of thick underwood, by the sides of small streams. It is very active, seizing much of its prey on wing, as well as among the leaves and bark of low trees. During the breeding-season, the male utters a few clear notes, resembling the syllables wheet-te-tee-hu, the last note being the loudest and shortest. At all other times, it is a very silent bird.

The nest which I found in the Pine Forest was placed in one of the forks of a low bush, not more than five feet from the ground. It was neat, compact, of small size, and formed of moss, stripes of vine-bark, and fibres of a kind of wild hemp, with a lining of fine bent-grass, and a few horse-hairs or fibres of moss. The eggs were five, roundish, of a delicate buff-colour, with a few spots at the larger end, where they appeared to be all collected. The female was so gentle that I put my hand close over her before she moved; and when she did so, she flew only a few feet, returning to her eggs whenever I retired a few yards. The male expressed his sorrow by a low tweet, but made no attempt to molest me.

Their food consists entirely of insects. Their flight is short, low, with a tremulous motion of the wings, unless when in pursuit of their prey. They all retire southward in the beginning of October.

Adult Male. Plate CXLVIII. Fig. 1.

Bill of ordinary length, nearly straight, broader than deep at the base, tapering, compressed toward the acute tip. Nostrils basal, oval, exposed. Head of ordinary size, neck short, body rather full. Feet of ordinary length, slender; tarsus compressed, covered anteriorly with a few long scutella, sharp behind; toes free, scutellate above; claws arched, much compressed, acute.

Plumage soft and blended, slightly glossed. Wings of ordinary length, the first quill longest. Tail longish, slightly emarginate, the feathers pointed.

Bill black above. Iris dark-brown. Legs flesh-coloured. The general colour of the plumage above is a rich olive-green, the quills and tail-feathers margined with paler; at the base of the primary quills a white spot, part of which is apparent beyond the primary coverts. A yellowish-white line over the eye, and a spot of the same beneath it. Cheeks and sides of the neck olivaceous. The under parts ochre-yellow, tinged with brown below the wings.

Length 5½ inches, extent of wings 7½; bill along the ridge 4/12, along the edge ½; tarsus ¾.

Adult Female. Plate CXLVIII. Fig. 2.

The Female resembles the male, but is paler in its tints.

Hobble Bush.

This species, which grows in the woods, from Canada to Virginia, is characterized by its large suborbicular, subcordate, unequally serrate, acute leaves, its dense cymes, and ovate berries, which are at first red, but ultimately black.
