About the Black-and-chestnut Eagle

The black-and-chestnut eagle, also known as Isidor's eagle, is a large South American species of bird of prey in the family Accipitridae. It is often placed in the monotypic genus Oroaetus. However, recent genetic testing indicates that this species is fairly closely related to Spizaetus species and thus the species should be included in that genus. The black-and-chestnut eagle is a typical forest raptor, hunting primarily small to medium-sized mammals and birds and constructing a large nest in a tall tree.
