Parabuteo unicinctus (Harris's Hawk; Harris' Hawk)

Synonyms: Falco unicinctus (homotypic)
Language: Spanish

Wikipedia Abstract

The Harris's hawk (Parabuteo unicinctus) formerly known as the bay-winged hawk or dusky hawk, is a medium-large bird of prey that breeds from the southwestern United States south to Chile, central Argentina, and Brazil. Birds are sometimes reported at large in Western Europe, especially Britain, but it is a popular species in falconry and these records almost certainly all refer to escapes from captivity.
