Polyborus plancus
The southern crested caracara (Caracara plancus), also known as the southern caracara or carancho, is a bird of prey in the family Falconidae. As presently defined, the southern crested caracara is restricted to central and southern South America. It formerly included the northern crested caracara (C. cheriway) of the southern United States, Mexico, Central America and northern South America, and the extinct Guadalupe caracara (C. lutosa) as subspecies. As its relatives, it was formerly placed in the genus Polyborus.
It has a total length of 50–65 cm (20–26 in) and a wingspan of 120–132 cm (47–52 in). Weight is 0.9-1.6 kg (2-3.5 lbs), averaging 1,348 g (2.972 lb) in 7 birds from Tierra del Fuego. Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings and tail-tip are dark brownish, the auriculars, throat and nape are whitish-buff, and the chest, neck, mantle, back, uppertail-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.
