      Gen. Char. Bill large and strong, swollen, and without any ridges; the lower mandible nearly as high as the upper; as broad at the base as the length of the gonys, and considerably broader than the upper mandible; the edges much inflexed, and shutting much within the upper mandible; the commissure considerably angulated at the base, then decidedly sinuated. The tarsus barely equal to the middle toe; the lateral toes nearly equal, not reaching to the base of the middle claw; the hind toe about equal to the middle one without its claw. The wings long and acute, reaching nearly to the middle of the tail; the tertials decidedly longer than the secondaries, but much shorter than the primaries; first quill longest, the others regularly graduated. Tail considerably shorter than the wings, though moderately long; nearly even, although slightly emarginate; the outer feathers scarcely shorter. Middle of back only striped; beneath without streaks.

      This genus comes nearer to Calamospiza, but has shorter tertials, more slender bill, weaker and more curved claws, etc.

      E. americana. Top and sides of head light slate; forehead tinged with greenish-yellow. A superciliary stripe, a maxillary spot, sides of breast, and middle line of breast and belly, yellow. Chin white, throat black, shoulders chestnut. Female with the black of the throat replaced by a crescent of spots. Hab. Eastern Province of United States; south to New Grenada.

      E. townsendi. Body throughout (including the jugulum), dark ash, tinged with brownish on the back and wings. Superciliary and maxillary stripe, chin, throat, and middle of belly, white. A maxillary line and a pectoral crescent of black spots. No chestnut shoulders. Hab. Chester Co., Pennsylvania.

      Sp. Char. Male. Sides of the head and sides and back of the neck ash; crown tinged with yellowish-green and faintly streaked with dusky. A superciliary and short maxillary line, middle of the breast, axillaries, and edge of the wing yellow. Chin, loral region, patch on side of throat, belly, and under tail-coverts white. A black patch on the throat diminishing to the breast, and ending in a spot on the upper part of the belly. Wing-coverts chestnut. Interscapular region streaked with black; rest of back immaculate. Length, about 6.70; wing, 3.50.

      Female with the markings less distinctly indicated; the black of the breast replaced by a black maxillary line and a streaked collar in the yellow of the upper part of the breast.

      Hab. United States from the Atlantic to the border of the high Central Plains, south to Panama and New Granada. Xalapa (Scl. 1857, 205); Guatemala (Scl. Ibis, I, 18); Turbo, N. G. (Cassin, P. A. N. S. 1860, 140); Panama (Lawr. VII, 1861, 298); Nicaragua, Graytown (Lawr. VIII, 181); Veragua (Salv. 1867, 142); Costa Rica (Lawr. IX, 103); Vera Cruz, winter (Sum. M. B. S. I, 552).

      Among adult males, scarcely two individuals exactly alike can be found. In some the black of the throat is continued in blotches down the middle of the breast, while in others it is restricted to a spot immediately under the head. These variations are not at all dependent upon any difference of habitat, for specimens from remote regions from each other may be found as nearly alike as any from the same locality. Some specimens from Central America are more deeply colored than North American ones, owing, no doubt, to the freshness of the plumage.

      Habits. The history of the Black-throated Bunting has, until very recently, been much obscured by incorrect observations and wrong descriptions. Evidently this bird has been more or less confounded with one or two other species entirely different from it. Thus Wilson, Audubon, and Nuttall, in speaking of its nest and eggs, give descriptions applicable to Coturniculus passerinus or to C. henslowi, but which are wholly wrong as applied to those of this bird. Nuttall, whose observations of North American birds were largely made in Massachusetts, speaks of this bird being quite common in that State, where it is certainly very rare, and describes, as its song, notes that have no resemblance to those of this Bunting, but which are a very exact description of the musical performances of the Yellow-winged Sparrow.

      It is found in the eastern portion of North America, from the base of the Black Hills to the Atlantic States, and from Massachusetts to South Carolina. I am not aware that on the Atlantic it has ever been traced farther south than that State, but farther west it is found as far at least as Southwestern Texas. During winter it is found in Central America, and in Colombia, South America.

      In Massachusetts it is extremely rare. Mr. Hopkins found it breeding in Williamstown, and sent me its eggs. I have also met with its nest and eggs, in a low meadow near the sea, in Hingham. In both of these instances the nest was on the ground. A specimen was shot in Newton by Mr. John Thaxter, June 26, 1857, that had all the appearance of being then in the process of incubation. Throughout Pennsylvania, and in the vicinity of Washington, these birds are quite common.

      Wilson states that they are very common in the vicinity of Philadelphia, where they make their appearance in the middle of May, and where they seem to prefer level fields covered with rye-grass, clover, or timothy. They are described as more conspicuous for the quantity than for the quality of their song. This consists of three notes, sounding like chip-chip-chē-chē-chē. Of this unmusical ditty they are by no means parsimonious, and for nearly three months after their first arrival, every level field of grain or grass resounds with their quaint serenade.
