Nisaetus
''Nisaetus'', the crested hawk-eagles, is a genus of raptor in the subfamily Aquilinae, found mainly in tropical Asia. They were earlier placed within the genus '' Spizaetus'' but molecular studies show that the Old World representatives of that genus are closer to the genus '' Ictinaetus'' than to the New World ''Spizaetus'' ( in the stricter sense). They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats. Taxonomy and species These Old World species were formerly placed in the genus '' Spizaetus''. They were moved to the resurrected genus ''Nisaetus'' based on the results of molecular genetic studies published in 2005 and 2007. The genus ''Nisaetus'' had been introduced in 1836 by the English naturalist Brian Houghton Hodgson with the mountain hawk-eagle as the type species. The genus name ''Nisaetus'' combines the Medieval Latin ''nisus'' for a sparrowhawk with the Ancient Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nisaetus Alboniger -Jurong Bird Park, Singapore-6a
''Nisaetus'', the crested hawk-eagles, is a genus of Accipitriformes, raptor in the subfamily Aquilinae, found mainly in tropical Asia. They were earlier placed within the genus ''Spizaetus'' but molecular studies show that the Old World representatives of that genus are closer to the genus ''Ictinaetus'' than to the New World ''Spizaetus'' (sensu stricto, in the stricter sense). They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, Stripe (pattern), barred wings, crests and usually adapted to forest habitats.

Changeable Hawk-eagle
The changeable hawk-eagle ''(Nisaetus cirrhatus)'' or crested hawk-eagle is a large bird of prey species of the family (biology), family Accipitridae. More informal or antiquated English common names include the marsh hawk-eagle or Indian crested hawk-eagle.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt. It is a member of the subfamily Aquilinae, with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus. It was formerly placed in the genus ''Spizaetus'', but studies pointed to the group being paraphyletic resulting in the Old World members being placed in ''Nisaetus'' and separated from the New World species. It is a typical "hawk-eagle" in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between birds, mammals or reptiles as well as other vertebrates.Naoroji, R., & Schmitt, N. J. (2007). ''Birds of prey of the Indian subcontinent''. Om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
