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.
The genus Perisoreus is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Species of Perisoreus jays are most closely related to the genus Cyanopica.
Accipiter is a genus of birds of prey in the family Accipitridae. With 49 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although with the exception of the American goshawk almost all New World species are simply known as "hawks". They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
Gyps is a genus of Old World vultures that was proposed by Marie Jules César Savigny in 1809. Its members are sometimes known as griffon vultures. Gyps vultures have a slim head, a long slender neck with downy feathers, and a ruff around the neck formed by long buoyant feathers. The crown of their big beaks is a little compressed, and their big dark nostrils are set transverse to the beak. They have six or seven wing feathers, of which the first is the shortest and the fourth the longest.
The lesser spotted eagle is a large Eastern European bird of prey. Like all typical eagles, it belongs to the family Accipitridae. The typical eagles are often united with the buteos, sea eagles, and other more heavy-set Accipitridae, but more recently it appears as if they are less distinct from the more slender accipitrine hawks than believed.
Circaetinae is a bird of prey subfamily which consists of a group of medium to large broad-winged species. The group is sometimes treated as tribe Circaetini. These birds mainly specialise in feeding on snakes and other reptiles, which is the reason most are referred to as "snake-eagles" or "serpent-eagles". The exceptions are the bateleur, a more generalised hunter, and the Philippine eagle, which preys on mammals and birds.
The black eagle is a bird of prey. Like all eagles, it is in the family Accipitridae, and is the only member of the genus Ictinaetus. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China. They hunt mammals and birds, particularly at their nests. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers.
The whistling ducks or tree ducks are a subfamily, Dendrocygninae, of the duck, goose and swan family of birds, Anatidae. In other taxonomic schemes, they are considered a separate family, Dendrocygnidae. Some taxonomists list only one genus, Dendrocygna, which contains eight living species, and one undescribed extinct species from Aitutaki of the Cook Islands, but other taxonomists also list the white-backed duck under the subfamily.
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.
The long-crested eagle is an African bird of prey characterised by its shaggy crest of feathers. In the family Accipitridae which includes all the eagles, it is currently placed in a monotypic genus Lophaetus. It is found throughout mid- and southern Africa, with differing home ranges due to food availability and suitable habitat area, but lives mainly on forest edges and near moist areas. Breeding may occur at any time of year, depending on food availability; it lays 1 or 2 eggs as is usual for raptors. It commonly eats smaller mammals, but will also eat other vertebrates and invertebrates.
The Indian spotted eagle is a large bird of prey native to South Asia. Like all typical eagles, it belongs to the family Accipitridae. The typical eagles are often united with the buteos, sea eagles and other more heavyset Accipitridae, but more recently it appears as if they are less distinct from the more slender accipitrine hawks.
Campylorhynchus is a genus of wrens, which has at least 15 described species. At 17–22 cm (6.8-8.7 in) long, these are the largest-bodied of wrens, including the largest species, the giant wren. Member species are found in South and Central America and in some cases, as far north as the southwestern United States.
Gurney's eagle is a large eagle in the family Accipitridae. It is found in New Guinea and Wallacea, and is an occasional vagrant to Australia.
The bazas, Aviceda, are a genus of bird of prey in the family Accipitridae. The genus has a widespread distribution from Australia to southern Asia and across to Africa. The bazas are sometimes known as cuckoo-hawks. A prominent crest is a feature of the bazas. They have two tooth-like indentations on the edge of the upper bill.
The black-collared hawk is a species of bird of prey in the family Accipitridae. It is monotypic within the genus Busarellus. It has a widespread range of presence, from western Mexico to Uruguay. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and swamps.
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).
Nisaetus 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. They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats.
The Jagdishpur Reservoir is a reservoir in Jahadi Village Development Committee, Kapilvastu District, Nepal which was named after Er. Jagadish Jha who designed and supervised the construction of Banaganga dam. With a surface area of 225 ha (2.25 km2), it is the largest reservoir in the country and an important wetland site. It is situated at an altitude of 197 m (646 ft). The maximum water depth varies between 2 m (6.6 ft) in the dry season and 7 m (23 ft) in the monsoon season.
The Harpiinae is a bird of prey subfamily which consists of large broad-winged species native to tropical forests. There are 4 genera in the subfamily, all monotypic.
