The Black-tailed Tityra, Tityra cayana, is a medium-sized passerine bird of tropical South America. The tityras have been placed in the cotinga or the tyrant flycatcher families by various authors. But the weight of evidence strongly suggest they and their closest relatives are better separated as Tityridae; the AOU for example advocates this separation. This is a short-tailed robust bird with a long hook-tipped bill; like other tityras it has a peculiar vestigial ninth primary feather. The adult Black-tailed Tityra is about 8-9 in long and weighs about 2-2.5 oz. The male is dull white above and white below. The rectrices, the primary and secondary remiges and a cap extending to below the eyes are black; the tertiary remiges are silvery grey.
