The Carib grackle (Quiscalus lugubris) is a New World tropical blackbird, a resident breeder in the Lesser Antilles and northern South America east of the Andes, from Colombia east to Venezuela and north-eastern Brazil. There are eight races, of which the most widespread is the nominate Q. l. lugubris of Trinidad and the South American mainland. This form was introduced to Tobago in 1905 and is now common there. The island races differ from the nominate form in size, plumage shade, especially in the browns of the females, and vocalisations.
