About Quiscalus lugubris Swainson, 1838
The adult male Carib grackle (scientific name: Quiscalus lugubris Swainson, 1838) measures 27 cm (11 in) in length, and has a long wedge-shaped tail that is shorter than the tail of other grackle species. Its entire plumage is black with violet iridescence; it has yellow eyes and a strong dark bill. The adult female is 23 cm (9.1 in) long, with a shorter tail and brown plumage that is darker on the upperparts. Young males have shorter tails than adult males, and their plumage includes some brown coloring. Young females are very similar in appearance to adult females. The seven recognized island subspecies differ from the nominate subspecies in body size, plumage shade (particularly the brown tones of female plumage), and vocalisations.
