 Adult Cuban orioles are black with a blue grey patch on the lower mandible and yellow patches on the coverts, rump, and upper thigh.The appearance of Cuban orioles is similar to that of Bahama, Puerto Rico, and Hispaniola orioles; a fact which contributed to the four birds being grouped into one species.Cuban orioles have the darkest coloration of the Greater Antillean orioles despite the fact that its closest relative, the Bahama oriole, displays the most yellow out of the same group.
