Spizaetus: Hawk Eagles

Eagles ... Birds of Prey ... The Sport of Falconry
Ornate Hawk-eagle, Spizaetus ornatus

Spizaetus is the typical hawk-eagle birds of prey genus found in the tropics of the Americas. It was however used to indicate a group of medium-large tropical eagles that included species occurring in southern and southeastern Asia and one representative of this genus in the rainforests of West Africa. The Old World species have been separated into the genus Nisaetus. Several species have a prominent head crest.

The American Ornithologists' Union merges Spizastur into Spizaetus since 2007.

Spizaetus eagles are forest birds with several species having a preference for highland woodlands. They build stick nests in trees
