The common grackle (Quiscalus quiscula) is a species of large icterid bird found in large numbers through much of North America. First described in 1758 by Carl Linnaeus, the common grackle has three subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have an iridescent appearance on their head, especially males. Common grackles can be found widely across North America east of the Rocky Mountains.
Taxonomy
The common grackle was first described in 1758 by Carl Linnaeus in the tenth edition of Systema Naturae, as Gracula quiscula. It was assigned to the genus Quiscalus by French ornithologist Louis Pierre Vieillot in his 1816 Dictionnaire d'histoire naturelle.
Three subspecies are recognized:
the Florida grackle (Q. q. quiscula) (Linnaeus 1758), the nominate subspecies
the purple grackle (Q. q. stonei) (Chapman, 1935)
the bronzed grackle (Q. q. versicolor) (Vieillot, 1816)
