The underparts are off-white and the wings are blackish with two white wing bars and white edges to the flight feathers. They have a long dark tail with white feather tips, a slim black bill with a slight downward curve, and long dark legs. The sexes are alike, but immature birds are duller and browner. M. g. tobagensis, found only on Trinidad and Tobago, has darker grey upper parts and more extensive white on the wing coverts and tail than the mainland forms. Learn more about Tropical Mockingbird
