| Tityra cayana (Linnaeus, 1766) |
The Black-tailed Tityra, Tityra cayana, is a medium-sized passerine bird. It was formerly placed in the cotinga family, but is now usually treated as a tyrant flycatcher, although Stiles and Skutch separate the tityras as part of a separate family, the Tityridae.
The Black-tailed Tityra breeds from Colombia, Trinidad and Venezuela south to northeastern Argentina and southeastern Brazil. This species is found in forest edges, second growth and plantation shade trees. The brown-marked buff eggs are laid in a bed of dry leaves in a tree hole, either in an old woodpecker nest or the crown of a dead palm tree. The female incubates alone, but both parents feed the chicks. Fledging is believed to take at least 3 weeks, and two broods may be raised in a seaon.
The adult Black-tailed Tityra is 22 cm long and weighs 60g. The male is greyish-white above and white below, except for the head, wings and tail, which are black. There is a patch of red bare skin around the eye, and the bill is red-based with a black tip. The female is similar, but darker grey above, with a brown crown and fine brown streaks on the back and breast.
Black-tailed Tityras are seen alone or in pairs, perched conspicuosly as they feed on medium-sized fruits. Some large insects are fed to the chicks. They have a buzzing weenk or doubled beeza-buzza call.
