The crested caracara (Caracara plancus) is a bird of prey in the family Falconidae. It is found from the southern United States through Central and South America to Tierra del Fuego. It was formerly placed in the genus Polyborus.
The cap, belly, thighs, most of the wings, and tail tip are dark brownish, the auriculars (feathers surrounding the ear), throat, and nape are whitish-buff, and the chest, neck, mantle, back, upper tail coverts, crissum (the undertail coverts surrounding the cloaca), and basal part of the tail are whitish-buff barred dark brownish. In flight, the outer primaries show a large conspicuous whitish-buff patch ('window'), as in several other species of caracaras. The legs are yellow and the bare facial skin and cere are deep yellow to reddish-orange. Juveniles resemble adults, but are paler, with streaking on the chest, neck, and back, grey legs, and whitish, later pinkish-purple, facial skin and cere.
