Tityra
The tityras are passerine birds in the genus Tityra of the family Tityridae. They are found from southern Mexico, through Central America, to northern and central South America, including Trinidad.
These are medium-sized birds, typically around long, with large bills. The adult males are greyish-white above and white below, except for the wings and tail which are at least partially black. The males of all three species also have black head markings. The females are similar, but are duller, with browner or greyer head markings. The black-tailed and the masked tityra both have a conspicuous red eye-ring and base of the bill.
