The Black-tailed Tityra (Tityra cayana) 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 20–22 centimetres (7.9–8.7 in) long and weighs about 60–70 grams (2.1–2.5 oz). The male is dull white above and white below. Black-tailed tityras are most commonly seen in pairs, or, less frequently, single or in small groups; they are intolerant of other birds and will try to chase them away. They are often seen perched conspicuously as they feed on medium-sized fruits. Food is gleaned from vegetation or picked off in mid-hover. While some large insects are caught, these are mainly fed to young birds; adults are predominantly frugivores.
