Icthyophaga
''Icthyophaga'' (often misspelled as ''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.del Hoyo, J., Elliott, A., & Sargatal, J., eds.

Lesser Fish Eagle
The lesser fish eagle (''Icthyophaga humilis'') 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 genus ''Icthyophaga''. Others place it in the genus ''Haliaeetus''. Lesser fish eagles are fish-eating birds that have feet adapted to aid in gripping slippery fish. They have strongly curved talons, and spicules along the underside of the birds' toes help to grip fish as they pull them from the water. There are two subspecies: ''Icthyophaga humilis humilis'', which is native to the Malaysian Peninsula, Sumatra, Borneo, and Sulawesi; and ''Icthyophaga humilis plumbeus'', which is native to Kashmir through ...

Sea Eagle (bird)
A sea eagle or fish eagle (also called erne or ern, mostly in reference to the white-tailed eagle) is any of the birds of prey in the subfamily Haliaeetinae of the bird of prey family Accipitridae. Ten extant species exist, currently described with this label. The subfamily has a significant reach, with a scholarly article in 2005 reporting that they were "found in riverine and coastal habitat throughout the world". However, ''Haliaeetinae'' inhabited areas have experienced particular threats given the context of human impacts on the environment. Taxonomy and evolution The genus ''Haliaeetus'' was introduced in 1809 by French naturalist Marie Jules César Savigny in his chapter on birds in the '' Description de l'Égypte''. The two fish eagles in the genus ''Ichthyophaga'' were found to lie within ''Haliaeetus'' in a genetic study in 2005. They were then moved accordingly. They are very similar to the tropical ''Haliaeetus'' species. A prehistoric (i.e. extinct before 1500) for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Grey-headed Fish Eagle
The grey-headed fish eagle (''Icthyophaga ichthyaetus'') is a fish-eating bird of prey from Southeast 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 (''Icthyophaga humilis'') 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. Taxonomy The grey-headed fish eagle is included in the order Accipitriformes and the family Accipitridae, which includes most birds of prey except for the ospreys and falcons. Lerner & Mindell placed the grey-headed fish eagle in the subfamily Haliaeetinae, which includes the genera '' Haliaeetus'' (sea eagles) It was first described by Horsfield i ...

African Fish Eagle
The African fish eagle (''Icthyophaga vocifer'') 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: ''visarend'' in Afrikaans, ''nkwazi'' in Chewa, ''aigle pêcheur'' in French, ''idì'' in Yoruba, ''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 occur on different continents, with the bald eagle being resident in North America. Taxonomy The African fish eagle is a species placed in the genus ''Icthyophaga'' ( fish eagles). Its closest relative appears to be the critically endangered Madagascar fish eagle (''I. vociferoides''). Like all sea eagle species pairs, this one consists of a white-headed ...

Icthyophaga Leucogaster
The white-bellied sea eagle (''Icthyophaga leucogaster''), 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 long with a wingspan of up to , and weigh . 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. Resident from India and Sri Lanka through Southeast Asia to Australia on coasts and major waterways, the white-be ...

Eagle
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family of the Accipitridae. Eagles belong to several groups of Genus, genera, some of which are closely related. True eagles comprise the genus ''Aquila (bird), Aquila''. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—two in North America, nine in Central and South America, and three in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Etymology The word "eagle" is borrowed into English from and , both derived ultimately from ("eagle"). It is cognate with terms such as , and . It is broadly synonymous with the less common English term "erne" or "earn", deriving from , from , in which it acts as the usual word for the bird. The Old English term is turn derived from and is cognate with other synonymous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sulawesi
Sulawesi ( ), also known as Celebes ( ), is an island in Indonesia. One of the four Greater Sunda Islands, and the List of islands by area, world's 11th-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and New Guinea, Papua are larger in territory, and only Java and Sumatra are more populous. The landmass of Sulawesi includes four peninsulas: the northern Minahasa Peninsula, the East Peninsula, Sulawesi, East Peninsula, the South Peninsula, Sulawesi, South Peninsula, and the Southeast Peninsula, Sulawesi, Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo. Etymology The n ...

Thomas Horsfield
Thomas Horsfield (May 12, 1773 – July 24, 1859) was an American physician and natural history, naturalist who worked extensively in Indonesia, describing numerous species of plants and animals from the region. He was later a curator of the East India Company Museum in London. Early life Horsfield was born in Bethlehem, Pennsylvania, and studied medicine at the University of Pennsylvania. He was the grandson of Timothy Horsfield, Sr. (1708-1773), who was born in Liverpool and emigrated to New York in 1725. The Horsfield family converted from the Church of England to Moravianism, a Protestant denomination with a strong emphasis on education. In 1748, he moved his family to Bethlehem, Pennsylvania and joined them the next year. Horsfield's father was Timothy Horsfield, Jr. and he married Juliana Sarah Parsons in 1738. Thomas Horsfield was born in Bethlehem on May 12, 1773. He was educated at the Moravian schools in Bethlehem and Nazareth, Pennsylvania, Nazareth. He studied medicin ...
