Quiscalus quiscula
male
Although superficially similar to a blackbird, the Common Grackle has a longer bill and a graduated tail that is folded lengthways and keeled. Males are larger than females and also differ in their plumage. Adult males across much of the range are black overall, with a blue sheen to the head, neck, and chest, a bronzed sheen on the body, and a bluish-purple tinge to the wings and tail. In birds from the southeast, the head and body have a purplish sheen. In all males, the eye has a pale iris. Adult females are similar to an adult male but duller, and they lack an obvious sheen. Juveniles are similar to an adult female but browner overall, and darkest and dullest on the wings and tail; the eye has a dark iris.
The Common Grackle is present year-round in southeast U.S.A., but in summer (mainly from May to September) its range extends north and east. It is easy to see in suburban environments and on farmland, and in spring males perform an interesting display.
