The common grackle (Quiscalus quiscula) is an icterid bird found in large numbers through much of North America. It was first described in 1758 by Carl Linnaeus and has three officially recognized subspecies. Adult common grackles have a long and dark bill, pale yellow eyes, and a long tail. Adults often have a bluish iridescent appearance on their head, this feature being more pronounced on males. Common grackles can be found widely across North America east of the Rocky Mountains and are highly adaptable to their environment.
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.

GBIF citizen-science records
It is estimated from how often the Common Grackle is recorded against all the birds logged in Minneapolis [Saint Paul] (10,946 verified sightings), calibrated against known sighting rates.
