southern crested caracara

The southern crested caracara (Caracara plancus), also known as the southern caracara or carancho, is a bird of prey in the family Falconidae. The classification of this species and name have evolved. It was formerly placed in the genus Polyborus. The use of the name formerly extended to two subspecies: the northern caracara (C. cheriway) of the southern United States, Mexico, Central America and northern South America, and the extinct Guadalupe caracara (C. lutosa) as subspecies. The use of the name southern caracara is now restricted to a bird that is found in central and southern South America.
