The Madagascar fish eagle (Icthyophaga vociferoides) or Madagascar sea-eagle (to distinguish it from the Ichthyophaga fishing-eagles), is a large bird of prey in the family Accipitridae which also includes many other diurnal raptors such as kites, buzzards and harriers. It is endemic to the coastal strip in the northwest of Madagascar. It is about 63cm (25in) long and has a pale brown head, dark brown body and white tail. The Madagascar fish eagle has been suffering from a declining population and is threatened by habitat destruction and persecution, and the International Union for Conservation of Nature has rated its conservation status as being "critically endangered".
The Madagascar fish eagle is a medium-sized sea eagle, 60–66cm (23.5–26in) long and with a wingspan of 165–180cm (65–71in).[3] The body and wings are dark brown, with a pale brown head and a white tail; the bill is blackish with a paler base, and the legs are pale grey.[4][pageneeded] Males weigh 2.2–2.6kg (4.9–5.7lb), while the slightly larger females weigh 2.8–3.5kg (6.2–7.7lb).[5]
Its closest relative is the African fish eagle, Icthyophaga vocifer. Together, they form a distinct species pair lineage of sea-eagles, which separated soon after the divergence of the genus; they retain the ancestral dark beak, talon, and eye, but unlike Haliaeetus species, they always have at least partially white tails, even while juvenile. As in other sea-eagle species pairs, one species (the Madagascan fish eagle in this case) has a tan head, while the other has a white one.[4][pageneeded]
Distribution
This species is endemic to Madagascar, where it survives in low numbers along the northwest coast north of Morondava. The range of this eagle is within the Madagascar dry deciduous forests.[6] The principal locus of population according to the United Nations Environmental Programme is in the Analova region; 20 to 25 breeding pairs were there as of the 1980s. A more recent survey by Garbutt and Hogan report a smaller concentration of at least three breeding pairs in the Anjajavy Forest along the Indian Ocean, where several streams discharge north of Anjajavy Village.[7]
Status
Total population estimates from the United Nations and from Grambo [8] place the world population of this species at about 40 breeding pairs; according to Grambo this bird may be one of the rarest birds on Earth. Other surveys between 1991 and 1995 recorded at least 222 adults from 105 sites, with an estimated 98 breeding pairs.

Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. True eagles comprise the genus Aquila. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia.
The white-tailed eagle, sometimes known as the 'sea eagle', is a very large bird of prey, widely distributed across temperate Eurasia. Like all eagles, it is a member of the family Accipitridae which includes other diurnal raptors such as hawks, kites, and harriers. One of up to eleven members in the genus Haliaeetus, which are commonly called sea eagles, it is also referred to as the white-tailed sea-eagle. Sometimes, it is known as the ern or erne, gray sea eagle and Eurasian sea eagle.
The white-bellied sea eagle, also known as the white-breasted sea eagle, is a large diurnal bird of prey in the family Accipitridae. Originally described by Johann Friedrich Gmelin in 1788, it is closely related to Sanford's sea eagle of the Solomon Islands, and the two are considered a superspecies. A distinctive bird, the adult white-bellied sea eagle has a white head, breast, under-wing coverts and tail. The upper parts are grey and the black under-wing flight feathers contrast with the white coverts. The tail is short and wedge-shaped as in all Haliaeetinae species. Like many raptors, the female is larger than the male, and can measure up to 90 cm (35 in) long with a wingspan of up to 2.2 m (7.2 ft), and weigh 4.5 kg (9.9 lb). Immature birds have brown plumage, which is gradually replaced by white until the age of five or six years. The call is a loud goose-like honking.
The cuckoo-roller or courol is the only bird in the family Leptosomidae, which was previously often placed in the order Coraciiformes but is now placed in its own order Leptosomiformes. The cuckoo-roller is at the root of a group that contains the Trogoniformes, Bucerotiformes, Piciformes, and Coraciiformes. Despite its name, the Cuckoo-roller does not share close evolutionary origins with cuckoos or rollers at all.
The grey-headed fish eagle is a fish-eating bird of prey from South East Asia. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle and the Pallas's fish eagle. The lesser fish eagle is similar in plumage but smaller and the Pallas's fish eagle shares the same habitat and feeding behaviour but is larger with longer wings and darker underparts. Is often called tank eagle in Sri Lanka due to its fondness for irrigation tanks.
The olive bee-eater or Madagascar bee-eater is a near passerine bee-eater species in the genus Merops. It is native to the southern half of Africa where it is present in Angola; Botswana; Burundi; Comoros; Democratic Republic of the Congo; Djibouti; Eritrea; Ethiopia; Kenya; Madagascar; Malawi; Mayotte; Mozambique; Namibia; Rwanda; Somalia; South Sudan; Sudan; Tanzania; Uganda; Zambia; Zimbabwe. It is a common species with a wide range so the International Union for Conservation of Nature has rated their conservation status as "least concern".
A sea eagle or fish eagle is any of the birds of prey in the subfamily Haliaeetinae in the bird of prey family Accipitridae. Ten extant species exist that are currently described with this label.
Icthyophaga or Ichthyophaga is a genus of six species of eagles, closely related to the sea eagles in the genus Haliaeetus. In fact, some taxonomic authorities place this genus within Haliaeetus. Both are native to southeastern Asia, from the Indian subcontinent southeast to Sulawesi. They are smaller than the Haliaeetus eagles, though overlapping in size with the smaller species of that genus. They share similar plumage, with grey heads grading into dull grey-brown wings and bodies, and white belly and legs. They differ in tail colour, with the lesser fish eagle having a brown tail, and the grey-headed fish eagle having a white tail with a black terminal band, and also in size, with the lesser fish eagle only about half of the weight of the grey-headed fish eagle.
The African fish eagle or the African sea eagle, is a large species of eagle found throughout sub-Saharan Africa wherever large bodies of open water with an abundant food supply occur. It is the national bird of Malawi, Namibia, Zambia, and Zimbabwe. As a result of its large range, it is known in many languages. Examples of names include: Vis Arend in Afrikaans, nkwazi in Chewa, aigle pêcheur in French, hungwe in Shona, inkwazi in isiZulu, and ntšhu in Northern Sotho. This species may resemble the bald eagle in appearance; though related, the two species occurs on different continents, with the bald eagle being resident in North America.
Steller's sea eagle, also known as Pacific sea eagle or white-shouldered eagle, is a very large diurnal bird of prey in the family Accipitridae. It was described first by Peter Simon Pallas in 1811. No subspecies are recognised. A sturdy eagle, it has dark brown plumage with white wings and tail, a yellow beak, and yellow talons. Typically, it is the heaviest eagle in the world, at about 5 to 10 kg, but in some standard measurements, may be ranked below the harpy eagle and the Philippine eagle.
Pallas's fish eagle, also known as Pallas's sea eagle or band-tailed fish eagle, is a large, brownish sea eagle. It breeds in the east Palearctic in Kazakhstan, Russia, Tajikistan, Turkmenistan, Uzbekistan, Mongolia, China, India, Nepal, Bangladesh, Myanmar and Bhutan. It is listed as Endangered on the IUCN Red List. It is partially migratory, with Central Asian birds wintering among the southern Asian birds in northern India, and also further west to the Persian Gulf.
The lesser fish eagle is a species of Icthyophaga found in the Indian subcontinent, primarily in the foothills of the Himalayas, and south-east Asia. There are records from Gujarat, Central India and in more recent times from the Kaveri river valley in southern India, although the south Indian records are now thought to come from an isolated population, disjunct from the species' normal range. Some taxonomic authorities place this species in the monotypic genus Icthyophaga. Others place it in the genus Haliaeetus.
Sanford's sea eagle, also known as Sanford's fish eagle or the Solomon eagle, is a sea eagle endemic to the Solomon Islands archipelago.
The Madagascar dry deciduous forests represent a tropical dry forest ecoregion situated in the western and northern part of Madagascar. The area has high numbers of endemic plant and animal species but has suffered large-scale clearance for agriculture. They are among the world's richest and most distinctive dry forests and included in the Global 200 ecoregions by the World Wide Fund. The area is also home to distinctive limestone karst formations known as tsingy, including the World Heritage Site of Bemaraha.
The little eagle is a very small eagle native to Australia, measuring 45–55 cm in length and weighing 815 g (1.8 lb), roughly the size of a peregrine falcon. It tends to inhabit open woodland, grassland and arid regions, shunning dense forest. It is a near relative of both the Palearctic booted eagle and the massive but now extinct Haast's eagle of New Zealand.
The Papuan eagle is a large bird of prey. It is also known by several other names, including Papuan harpy eagle, New Guinea eagle, New Guinea harpy eagle, or kapul eagle, the latter name from the local name for a usually arboreal, marsupial that the eagle is known to regularly hunt. This is an endemic species to New Guinea, and it can occasionally be found throughout the island. This is a forest-dwelling species, usually occurring in mature rainforest. The Papuan eagle is a fairly little-known species for a large eagle; however, it is known to prey on a wide range of prey, probably by and large mammals and birds from small to quite large sizes. What little study has been conducted about their breeding habits suggests they nest in a large forest tree, perhaps every other year. The Papuan eagle is probably naturally scarce, but it is under the threat of habitat destruction by deforestation, as well as hunting. Due to its small and declining population, the species has been classified as vulnerable by the IUCN.
The Anjajavy's Protected Area is located on a peninsula of the town of Antonibe, in the district of Analalava and in the north-west region of Madagascar. It is part of the Sofia region of the independent province of Mahajanga and its position is between 47°13’ at 44°22’ of longitude east and 14°58 at 15°07’ of latitude south..
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.
Henst's goshawk is a species a bird of prey in the family Accipitridae. It is a large, diurnal bird endemic to the island of Madagascar. It is an obligate forest species that occurs at very low densities on the island and is rarely seen. It can only occupy the primary and secondary forests found within the island. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and plantations.
The Sakalava rail is a species of bird in the family Rallidae. It is endemic to western Madagascar. This bird is small with brown upperpart feathers, grey underparts, a yellow bill and red legs.
