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.
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. [1] [2] [3] The genus Nisaetus had been introduced in 1836 by the English naturalist Brian Houghton Hodgson with the mountain hawk-eagle as the type species. [4] The genus name Nisaetus combines the Medieval Latin nisus for a sparrowhawk with the Ancient Greek aetos meaning "eagle". [5] The genus contains ten species. [6]

Buteo is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in the New World. As both terms are ambiguous, buteo is sometimes used instead, for example, by the Peregrine Fund.
Accipiter is a genus of birds of prey in the family Accipitridae. Most species are called sparrowhawks, but there are many sparrowhawks in other genera too, such as Tachyspiza.
The gray-headed kite is a raptor found in open woodland and swamp forests. It shares the genus Leptodon with the extremely rare white-collared kite. It breeds from eastern Mexico and Trinidad south to Peru, Bolivia, Brazil and northern Argentina.
Aquila is the genus of true eagles. The genus name is Latin for "eagle", possibly derived from aquilus, "dark in colour". It is often united with the sea eagles, buteos, and other more heavyset Accipitridae, but more recently they appear to be less distinct from the slenderer accipitrine hawks than previously believed. Eagles are not a natural group but denote essentially any bird of prey large enough to hunt sizeable vertebrate prey.
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 55 and 75 cm long, and tend to be long-tailed and slender.
Blyth's hawk-eagle is a medium-sized bird of prey. Like all eagles, it is in the family Accipitridae.
The Javan hawk-eagle is a medium-sized, dark brown raptor in the family Accipitridae. It is the national bird of Indonesia, where it is commonly referred to as the real-life model for the Garuda Pancasila, which is also inspired by Garuda; a bird-like deity in Hinduism and Buddhism. The scientific name commemorates the Bartels family, who discovered it.
The Flores hawk-eagle is a large raptor in the family Accipitridae. It is an endemic species to the Lesser Sunda Islands in Indonesia. 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. A forest dwelling predator, this species is classified as Critically Endangered due to habitat loss and persecution.
The Sulawesi hawk-eagle, also known as Celebes hawk-eagle, is a medium-sized, approximately 64 cm (25 in) long, crestless brown raptor in the family Accipitridae. The adults have rufous-brown, boldly marked head and chest feathers, dark brown wings and black-barred white below. The young has white head and underparts.
Cassin's hawk-eagle or Cassin's eagle, is a relatively small eagle in the family Accipitridae. Its feathered legs mark it as member of the Aquilinae or booted eagle subfamily. A forest-dependent species, it occurs in primary rainforests across western, central and (marginally) eastern Africa where it preys on birds and tree squirrels. It was named after John Cassin who first described it in 1865. Due to widespread habitat destruction, its populations are steadily declining but have not yet warranted upgrading its status from Least Concern.
Wallace's hawk-eagle is a species of bird of prey in the family Accipitridae. It is found in Kra Isthmus, Malay Peninsula, Sumatra and Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss and trade. It is among the smallest eagles in the world at about 46 cm (18 in) long and weighing 500–610 g (1.10–1.34 lb).
The Philippine hawk-eagle or north Philippine hawk-eagle, earlier treated under Spizaetus, is a species of bird of prey in the family Accipitridae. Many taxonomists consider the Pinsker's hawk-eagle, a former subspecies, raised to full species status. It is endemic to the Philippines. Its natural habitat is tropical moist lowland forests. It is threatened by habitat loss and trapping.
The brown-chested jungle flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It breeds in South China and winters in the Malay Peninsula. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It is threatened by habitat loss.
The Sula jungle flycatcher is a species of passerine bird in the Old World flycatcher family Muscicapidae. It is endemic to Sula Island in Indonesia where its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
The fulvous-chested jungle flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It is found in Brunei, Indonesia, Malaysia, Myanmar, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests.
The grey-chested jungle flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It is found in Brunei, Indonesia, Malaysia, and Thailand. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps. It is threatened by habitat loss.
Pinsker's hawk-eagle, 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.
