The variable seedeater (Sporophila corvina) is a passerine bird which breeds from southern Mexico through Central America to the Chocó of northwestern South America. The taxonomy is confusing, and it was formerly considered a subspecies of Sporophila americana. Even within the variable seedeater as presently defined, there are great variations in plumage. Order: Passeriformes, Family: Thraupidae, Genus: Sporophila, Species: Sporophila corvina (Sclater, 1860).
