High Quality Content by WIKIPEDIA articles! The Indigo Bunting, Passerina cyanea, is a small seed-eating bird in the 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, brush areas, and open woodland. The Indigo Bunting is closely related to the Lazuli Bunting, and interbreeds with the latter species where their ranges overlap.
