The male boat-tailed grackle (Quiscalus major) has an entirely iridescent black plumage and a long keel-shaped tail. The female has a shorter tail and tawny-brown coloration. Boat-tailed grackles inhabit several United States Gulf Coast cities and towns, where they can be found foraging in trash bins, dumpsters, and parking lots. Boat-tailed Grackles from different regions (East Coast, Florida, west of Florida to Louisiana and west of Louisiana) have different eye colours. The reason is unknown.
