Spizaetus
''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 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. These are medium to large-sized raptors, most being between long, and tend to be long-tailed and slender. 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. The sexes are similarly plumaged with typical raptor brown upperparts and pale underparts, but young birds are distinguishable from adults, often by a whiter head. These eagles eat medium-sized vertebrate prey such as mammals, birds and reptiles. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornate Hawk-eagle
The ornate hawk-eagle (''Spizaetus ornatus'') is a fairly large bird of prey from the Tropics, tropical Americas. Formerly, some authorities referred to this species as the crested hawk-eagle, a name that may cause some confusion as it is more commonly used for an Changeable hawk-eagle, Asian eagle species.Friedmann H. (1935). ''A new race of the Crested Hawk-eagle Spizaetus ornatus''. Journal of the Washington Academy of Sciences, 25 (10): 450-451. Like all eagles, it is in the family Accipitridae. This species has a feathered tarsus that marks it as a member of the ''Aquilinae'' or booted eagle subfamily.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301-320. This species is notable for the vivid colors and bold ma ...
