Nisaetus
''Nisaetus'' (Crested hawk-eagles group) is a genus of subfamily Aquilinae found mainly in tropical Asia. They were earlier placed within the genus ''Spizaetus'' but molecular studies show that the Old World representatives were 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 The mountain hawk-eagle (''Nisaetus nipalensis'') or Hodgson's hawk-eagle, is a large bird of prey native to Asia.

Changeable Hawk-eagle
The changeable hawk-eagle ''(Nisaetus cirrhatus)'' or crested hawk-eagle is a large bird of prey species of the 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 Books Int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nisaetus Nipalensis
The mountain hawk-eagle (''Nisaetus nipalensis'') or Hodgson's hawk-eagle, is a large bird of prey native to Asia. The latter name is in reference to the naturalist, Brian Houghton Hodgson, who described the species after collecting one himself in the Himalayas. A less widely recognized common English name is the feather-toed eagle. Like all eagles, it is in the family Accipitridae. Its feathered tarsus marks this species as a member of the subfamily Aquilinae. It is a confirmed breeding species in the northern part of the Indian subcontinent, from India, Nepal (hence the epithet ''nipalensis'') through Bangladesh to Thailand, Taiwan, Vietnam and Japan, although its distribution could be wider still as breeding species.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt.Grimmett, R.; Inskipp, C., Inskipp, T. & Byers, C. (1999).

Flores Hawk-eagle
The Flores hawk-eagle (''Nisaetus floris'') is a large raptor in the family Accipitridae. It is an endemic species to the Lesser Sunda Islands in Indonesia.Verhoeye, J. & Holmes. D. A. (1998). ''The birds of the islands of Flores -- a review''. Kukila 10:3-59. A member of the genus ''Nisaetus'', it was considered as a subspecies of and conspecific with the changeable hawk-eagle but genetic studies have evidenced it as a legitimate species.Gjershaug, J.

Nisaetus Kelaarti
Legge's hawk-eagle (''Nisaetus kelaarti'') is a bird of prey. Like all eagles, it is in the family Accipitridae. It breeds in the Indian subcontinent, from southern India to Sri Lanka. Its specific name ''kelaarti'' honors the physician-zoologist E.F. Kelaart. Legge's hawk-eagle is a medium-sized eagle and fairly large-sized raptor. The typical adult has brown upperparts and pale underparts, with barring on the undersides of the flight feathers and tail. The breast and belly are heavily streaked. The wings are broad with a curved trailing edge, and are held in a shallow V in flight. Sexes are similar, but young birds are often whiter-headed. Legge's hawk-eagle was formerly considered to be a subspecies of the mountain hawk-eagle, but it is smaller and has unstreaked buff underwing coverts. A 2008 study based on the geographic isolation and differences in call suggested that this be treated as a full species, ''Nisaetus kelaarti''.Gjershaug, J. O.; Diserud, O. H.; Rasmussen ...

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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nisaetus Pinskeri
Pinsker's hawk-eagle (''Nisaetus pinskeri''), south Philippine hawk-eagle or Mindanao hawk-eagle, is a species of bird of prey in the family Accipitridae. It is endemic to the Philippines native to the islands of Leyte, Samar, Negros, Basilan, Bohol and Mindanao. It is found in primary moist lowland forest and tropical moist montane forest up to 1,900 m. It is threatened by habitat loss and hunting. IUCN estimates just 600–800 mature birds left. Description It is most closely related to the Philippine hawk-eagle (''Nisaetus philipensis'') with some taxonomists still considering it a subspecies, and Changeable hawk-eagle (''Nisaetus cirrhatus'') and hawk eagle species which is commonly distributed in Southeast Asia. EBird describes the bird as "A fairly large raptor of lowland and foothill forest in the southern Philippines. Dark brown above and whitish below with a streaked head and chest and a finely barred lower belly. Note the long hind crest and the chin stripe. In fligh ...
