Sea Cow Island
Sea Cow Island, also known as Île Vache Marine, is a round 18 ha island on the Great Chagos Bank atoll of the Chagos Archipelago in the British Indian Ocean Territory. History It was named after the dugongs that were once abundant in the area, although they have since become regionally extinct. It is the smaller of the two islands in the Eagle Islands group on the western side of the atoll and forms part of the Chagos Archipelago strict nature reserve. It has been identified as an Important Bird Area by BirdLife International because of its significance as a breeding site for brown noddies, of which 11,500 pairs were recorded in a 2004 survey. The whole shore of this island and some of the interior can be explored through Google Street View Google Street View is a technology featured in Google Maps and Google Earth that provides interactive panoramas from positions along many streets in the world. It was launched in 2007 in several cities in the United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eagle Islands ISS006
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. Most of the 68 species of eagle 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. 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. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smallest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Chagos Bank
The Great Chagos Bank, in the Chagos Archipelago, about south of Maldives, is the largest atoll structure in the world, with a total area of . The atoll is administered by the United Kingdom through the British Indian Ocean Territory (BIOT). Islands Despite its enormous size, the Great Chagos Bank is largely a submarine structure. There are only four emerging reefs, mostly located on the western rim of the atoll, except for lonely Nelson Island, which lies wholly isolated in the middle of the northern fringe. These reefs have eight individual low and sandy islands, with a total land area of about . All islands and their surrounding waters are a Strict Nature Reserve since 1998. The total length of the eastern and southern expanses of the bank, as well as the reefs in its central area are wholly submerged. The islands of the Great Chagos Bank, starting clockwise from the south, are: * Danger Island (slightly more than long from North to South, by wide, land area , vege ...

Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. ''The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory.'' ''Annual Review of Marine Science'', 13, pp.537-573. According to Charles Darwin's ''subsidence model'', the formation of an atoll is explained by the subsidence of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef becomes a ...

Chagos Archipelago
The Chagos Archipelago () or Chagos Islands (formerly the Bassas de Chagas, and later the Oil Islands) is a group of seven atolls comprising more than 60 islands in the Indian Ocean about 500 kilometres (310 mi) south of the Maldives archipelago. This chain of islands is the southernmost archipelago of the Chagos–Laccadive Ridge, a long submarine mountain range in the Indian Ocean. In its north are the Salomon Islands, Nelson's Island and Peros Banhos; towards its south-west are the Three Brothers, Eagle, Egmont and Danger Island(s); southeast of these is Diego Garcia, by far the largest island. All are low-lying atolls, save for a few extremely small instances, set around lagoons. The Chagos Islands had been home to the native Chagossians, a Bourbonnais Creole-speaking people, until the United Kingdom expelled them from the archipelago at the request of the United States between 1967 and 1973 to allow the United States to build a military base on Diego Garcia. Since 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Indian Ocean Territory
The British Indian Ocean Territory (BIOT) is an Overseas Territory of the United Kingdom situated in the Indian Ocean, halfway between Tanzania and Indonesia. The territory comprises the seven atolls of the Chagos Archipelago with over 1,000 individual islandsmany very smallamounting to a total land area of . The largest and most southerly island is Diego Garcia, , the site of a Joint Military Facility of the United Kingdom and the United States. The only inhabitants are British and United States military personnel, and associated contractors, who collectively number around 3,000 (2018 figures). The forced removal of Chagossians from the Chagos Archipelago occurred between 1968 and 1973. The Chagossians, then numbering about 2,000 people, were expelled by the UK government to Mauritius and Seychelles in order to construct the military base. Today, the exiled Chagossians are still trying to return, saying that the forced expulsion and dispossession was unlawful, but the ...

Dugong
The dugong (; ''Dugong dugon'') is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees. It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (''Hydrodamalis gigas''), was hunted to extinction in the 18th century. The dugong is the only sirenian in its range, which spans the waters of some 40 countries and territories throughout the Indo-West Pacific. The dugong is largely dependent on seagrass communities for subsistence and is thus restricted to the coastal habitats which support seagrass meadows, with the largest dugong concentrations typically occurring in wide, shallow, protected areas such as bays, mangrove channels, the waters of large inshore islands and inter-reefal waters. The northern waters of Australia between Shark Bay and Moreton Bay are believed to be the dugong's contemporary stronghold. Like all modern sirenians, the dugong ...

Eagle Islands
Eagle Islands is a group of two islands in the Chagos Archipelago. They are located on the central-western rim of the Great Chagos Bank, which is the world's largest coral atoll structure. Islands With a land area of 2.45 km, Île Aigle is the largest single island of the Great Chagos Bank, and after Diego Garcia the second largest of the Chagos Archipelago. *Eagle Island (Île Aigle) *Sea Cow Island (Île Vache Marine) History There was once a coconut plantation in Ile Aigle, as well as a small settlement of Chagossian plantation workers. But at the time of Commander Robert Moresby's survey of the Chagos, in 1838, this island was populated only occasionally. Not long after the settlement of the Chagos group by the French planters at the end of the 18th century, the tendency was to concentrate the workers on only a few islands from which the plantations were run, like Ile Boddam in the Salomon Atoll. In 1975 during the Joint Services Expedition to Danger Island (JSDI), t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Noddy
The brown noddy or common noddy (''Anous stolidus'') is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. The brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve. Taxonomy The first formal description of the brown noddy was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' u ...
