Grey-headed Fish Eagle
The grey-headed fish eagle (''Haliaeetus ichthyaetus'') is a fish-eating bird of prey from South East Asia.Robson, C. (2000). ''A Field Guide to the Birds of South-East Asia''. UK: New Holland Publishers. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs.Rasmussen, P. C. & Anderton, J. C. (2005). ''Birds of South Asia''. The Ripley Guide. Vols 1 and 2. Washington D.C. and Barcelona: Smithsonian Institution and Lynx Edicions. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle (''Haliaeetus 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.Ferguson-Lees, J. & Christie, D. A. (2001). ''Raptors of the World''. London, UK: Christ ...

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. In New York, his brother Isaac and he ran a butcher shop. The Horsfield family converted from the Church of England to Moravianism, a Protestant denomination with a strong emphasis on education. In 1748, Horsfield, Sr. applied for permission to reside in Bethlehem, Pennsylvania. He, however, moved only his family to Bethlehem and joined them the next year. When Northampton County was created in 1752, he was made a justice of peace by Governor Hamilton. In 1763 he was commissio ...

Ichthyophaga
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 genus ''Haliaeetus'' in the bird of prey family Accipitridae. 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) form from Maui in the Hawaiian Islands may represent a species or subspecies in this genus. The relationships to other genera in the family are less clear; they have long been considered closer to the genus ''Milvus'' (kites) than to the true eagles in the genus '' Aquila'' on the basis of their morphology and display behaviour;Brown, L. H, & Amadon, D. (1968) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Southeast Asia
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mekong River
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to Chin ...

Piscivore
A piscivore () is a carnivorous animal that eats primarily fish. The name ''piscivore'' is derived . Piscivore is equivalent to the Greek-derived word ichthyophage, both of which mean "fish eater". Fish were the diet of early tetrapod evolution (via water-bound amphibians during the Devonian period); insectivory came next; then in time, the more terrestrially adapted reptiles and synapsids evolved herbivory. Almost all predatory fishes (most sharks, tuna, billfishes, pikes etc.) are obligated piscivores. Some non-piscine aquatic animals, such as whales, sea lion and crocodilians, are not completely piscivorous, often also preying on invertebrates, marine mammals, waterbirds and even wading land animals in addition to fish; while others, such as the bulldog bat and gharial, are strictly dependent on fish for food. Some creatures, including cnidarians, octopuses, squid, spiders, cetaceans, grizzly bears, jaguars, wolves, snakes, turtles and sea gulls, may have fish as signific ...

Tonlé Sap
Tonlé Sap (; km, ទន្លេសាប, ; or commonly translated as 'Great Lake'; vi, Biển Hồ, Chữ Hán: 湖海/壺海) is a lake in the northwest of Cambodia. It belongs to the Mekong, Mekong River system. It is the largest freshwater lake in Southeast Asia and one of the most diverse and productive ecosystems in the world, designated as a Biosphere Reserve by UNESCO in 1997 due to its high biodiversity. Entering the 21st century, the lake and its surrounding ecosystems are under increasing pressure from Deforestation in Cambodia, deforestation, infrastructure development and Climate change in Cambodia, climate change. Geography Tonlé Sap Lake is located in the northwest of the lower Mekong plain, formed by the collision and collapse of the Indian Plate and the Eurasian Plate. The lower Mekong plain used to be a bay, and the sea level rose rapidly at the end of the last glacial period. About high, cores from this period found near Angkor contain tidal deposits ...
