Cock-tailed tyrant  (Alectrurus tricolor)

A displaying species, the male cock-tailed tyrant flaunts elongated tail feathers that fan out in a crescent. Males are mostly black above, with a grey rump and white between the top of the wings. There is a black patch on the sides of the breast and the tail is black. In strong contrast, the face and underparts are white. Females are similar to males, but are brown rather than black and have a normal-shaped, short tail (2).
