The chimango caracara (Milvago chimango) is a species of bird of prey in the family Falconidae, the falcons and caracaras. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay, and as a vagrant on the Falkland Islands. Taxonomy and systematics The taxonomy of the caracaras has not been settled. The American Ornithological Society and the International Ornithological Committee place the chimango and yellow-headed caracaras in genus Milvago. BirdLife International's Handbook of the Birds of the World places the chimango caracara and four others in genus Phalcoboenus and the yellow-headed caracara alone in Milvago. The Clements taxonomy places the chimango, yellow-headed, and four other caracaras in genus Daptrius. The other systems place only the black caracara in Daptrius. The worldwide systems agree that the chimango caracara has two subspecies, the nominate M. c. chimango (Vieillot, 1816) and M. c. temucoensis (Sclater, 1918). The population in Tierra del Fuego has sometimes been proposed as a third subspecies, M. c. fuegiensis. Description The chimango caracara is long and weighs . Its wingspan is . The sexes' plumages are alike. Adults of the nominate subspecies are mostly brownish throughout. They have dark streaks on the side of the head and on their hindneck. Their undersides are mottled or barred with rufous brown. Their uppertail coverts are white and their tail is mottled grayish and white with a wide black band near the end. Their iris is brown. Males have bare yellow skin around the eye and yellow legs and feet. Females have reddish pink skin around the eye and bluish gray legs and feet. Juvenile birds have a strong rufous tinge overall and bare parts colored like the adult female's. Subspecies M. c. temucoensis is a darker smoky brown than the nominate, and their underparts are more heavily marked. Distribution and habitat The nominate subspecies of the chimango caracara is found in northern and central Chile and from central Argentina east through Paraguay, southern Brazil, and Uruguay to the Atlantic Ocean. It is also a non-breeding visitor north into Bolivia. Subspecies M. c. temucoensis is found from southern Chile at about Concepción Province and southern Argentina at about the Chubut River south through Tierra del Fuego to Cape Horn. Individuals have roamed to the Falkland Islands. In addition, the species was introduced to Easter Island in the early 20th century. The chimango caracara inhabits a wide variety of open landscapes including grassy
