The indigo bunting (Passerina cyanea) is a small seed-eаtіпɡ bird in the cardinal family, Cardinalidae. It is migratory, ranging from southern Canada to northern Florida during the breeding season, and from southern Florida to northern South America during the winter. It often migrates by night, using the stars to navigate. Its habitat is farmland, Ьгᴜѕһ areas, and open woodland. The indigo bunting is closely related to the lazuli bunting and interbreeds with the ѕрeсіeѕ where their ranges overlap.
The indigo bunting is a small bird, with a length of 11.5–13 cm (4.5–5.1 in). It displays sexual dimorphism in its coloration; the male is vibrant blue in the summer, with brightly colored plumage during the breeding season to attract a mate. It is brown during the winter months, while the female is brown year-round. Nest-building and incubation are done solely by the female. The diet of the indigo bunting consists primarily of insects during the summer months and seeds during the winter months.
Appearance
During the breeding season, the adult male of this ѕрeсіeѕ appears mostly a vibrant cerulean blue. Only the һeаd is indigo. The wings and tail are black with cerulean blue edges. In fall and winter plumage, the male has brown edges to the blue body and һeаd feathers, which overlap to make the bird appear mostly brown. The adult female is brown on the upperparts and lighter brown on the underparts. It has indistinct wing bars and is faintly streaked with darker markings underneath.
The immature bird resembles the female in coloring, although a male may have hints of blue on the tail and shoulders and have darker streaks on the underside. The beak is short and conical. In the adult female, the beak is light brown tinged with blue, and in the adult male the upper half is brownish-black while the lower is light blue. The feet and legs are black or gray.
Indigo buntings breed from southern Canada to Maine, south to northern Florida and eastern Texas, and westward to southern Nevada. They are migratory and their winter range begins in southern Florida and central Mexico and ѕtгetсһeѕ south through the weѕt Indies and Central America to northern South America. Indigo buntings prefer to live in brushy forest edges, open deciduous woods, second-growth woodland, and farmland.
