 The black catbird is endemic to the Yucatán Peninsula . It occurs as far south as the Mexican state of Campeche , northern Guatemala and northern Belize , and is found on the offshore islands of Cozumel , Isla Mujeres , Ambergris Caye , Caye Caulker , Lighthouse Reef and Glover 's Reef . Although the type specimen of the bird was apparently collected in northwestern Honduras in 1855 or 1856 , it has not been recorded in that country since , and must have been rare if it was ever there . Some authors feel that the specimen might have been mislabeled , and have come instead from northwestern " British Honduras " as Belize was then called . There is also a single specimen of a black catbird collected from Brownsville , Texas in 1892 . Although obtained by a reportedly reputable collector , and accepted by the Texas State Records Committee , the origin of this specimen is a source of some controversy , and it has not been accepted by the American Birding Association or the American Ornithologists ' Union .
