Marie Louise Island
Marie Louise Island is a low-lying coral island in the Amirantes group of the Outer Islands of the Republic of Seychelles, in the western Indian Ocean, with a distance of 308 km south-west of Victoria, Seychelles. History The Island was named by the Chevalier du Roslan in 1771 after his ship Marie Louise. Since the end of the 19th century, the island has been leased and inhabited without interruption. In 1905, the population numbered 86. There was an export of 3500 tons of guano that year. Guano had been the main economy until 1963, when still 3000 tons were produced. Additional products were copra and dried fish. In the 1980s there have been attempts in developing the island into a tourist destination. Some bungalows were constructed. The attempts failed because of air traffic limitations due to the large number of seabirds. Additionally, aircraft landing is difficult, because of the steep coast that is littered with rocks. In 2012 the government established a new pris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gurkha
The Gurkhas or Gorkhas (), with endonym Gorkhali ), are soldiers native to the Indian Subcontinent, chiefly residing within Nepal and some parts of Northeast India. The Gurkha units are composed of Nepalis and Indian Gorkhas and are recruited for the Nepali Army (96000), Indian Army (42000), British Army (4010), Gurkha Contingent Singapore, Gurkha Reserve Unit Brunei, UN peacekeeping forces and in war zones around the world. Gurkhas are closely associated with the ''khukuri'', a forward-curving knife, and have a reputation for military prowess. Former Indian Army Chief of Staff Field Marshal Sam Manekshaw once stated that: "If a man says he is not afraid of dying, he is either lying or he is a Gurkha." Origins Historically, the terms "Gurkha" and "Gorkhali" were synonymous with "Nepali", which originates from the hill principality Gorkha Kingdom, from which the Kingdom of Nepal expanded under Prithvi Narayan Shah. The name may be traced to the medieval Hindu warrior-sai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawksbill Sea Turtle
The hawksbill sea turtle (''Eretmochelys imbricata'') is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus ''Eretmochelys''. The species has a global distribution, that is largely limited to tropical and subtropical marine and estuary ecosystems. The hawksbill's appearance is similar to that of other marine turtles. In general, it has a flattened body shape, a protective Carapace#Turtles and tortoises, carapace, and flipper (anatomy), flipper-like limbs, adapted for swimming in the open ocean. ''E. imbricata'' is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the wikt:serration, saw-like appearance of its shell margins. Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs. The IUCN, World Conservation Union, primarily as a result o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Sea Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit shallow lagoons, feeding mostly on various ...

White Tern
The white tern or common white tern (''Gygis alba'') is a small seabird found across the tropical oceans of the world. It is sometimes known as the fairy tern, although this name is potentially confusing as it is also the common name of '' Sternula nereis''. Other names for the species include angel tern and white noddy in English, and manu-o-Kū in Hawaiian. The little white tern ('' Gygis microrhyncha''), previously considered a subspecies of the white tern (''Gygis alba microrhyncha''), is now recognised as a separate species. Taxonomy The white tern was first formally described by the Swedish naturalist Anders Sparrman in 1786 under the binomial name ''Sterna alba''. The genus ''Gygis'' was introduced by the German zoologist Johann Georg Wagler in 1832. The name ''Gygis'' is from the Ancient Greek for a mythical bird and the specific is Latin for "white". Molecular phylogenetic studies have shown that the white tern is more closely related to the noddies than it is to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Noddy
The lesser noddy (''Anous tenuirostris''), also known as the sooty noddy, is a seabird in the family Laridae. It is found near the coastlines of Comoros, Kenya, India, Maldives, Mauritius, Seychelles, Somalia, Sri Lanka and United Arab Emirates. The lesser noddy was at one time considered as a subspecies of the black noddy (''Anous minutus''). The close relationship between the two species was confirmed by a molecular phylogenetic study published in 2016. Taxonomy The first formal description of the lesser noddy was by the Dutch zoologist Coenraad Jacob Temminck in 1823 under the binomial name ''Sterna tenuirostris''. The genus ''Anous'' was introduced by the English naturalist James Francis Stephens in 1826. ''Anous'' is Ancient Greek for "stupid" or "foolish". The specific name ''tenuirostris'' is from the Latin ''tenuis'' for "slender" and ''-rostris'' "-billed". There are two subspecies: *''A. t. tenuirostris'' (Temminck, 1823) - islands of the west & north Indian Ocean *'' ... [...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 ...

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

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] |
Sooty Tern
The sooty tern (''Onychoprion fuscatus'') is a seabird in the family Laridae. It is a bird of the tropical oceans, returning to land only to breed on islands throughout the equatorial zone. Taxonomy The sooty tern was described by Carl Linnaeus in 1766 as ''Sterna fuscata'', bearing this name for many years until the genus ''Sterna'' was split up. It is now known as ''Onychoprion fuscatus''. The genus name is from ancient Greek , "claw" or "nail", and , "saw". The specific ''fuscatus'' is Latin for "dark". Colloquially, it is known as the wideawake tern or just wideawake. This refers to the incessant calls produced by a colony of these birds, as does the Hawaiian name ''ʻewa ʻewa'' which roughly means "cacophony". In most of Polynesia its name is ''manutara'' or similar – literally "tern-bird", though it might be better rendered in English as "the tern" or "common tern". This refers to the fact that wherever Polynesian seafarers went on their long voyages, they usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casuarina Equisetifolia
''Casuarina equisetifolia'', common names ''Coastal She-oak'' or ''Horsetail She-oak'' (sometimes referred to as the Australian pine tree or whistling pine tree outside Australia), is a she-oak species of the genus ''Casuarina''. The native range extends throughout Southeast Asia, Northern Australia and the Pacific Islands; including Thailand, Myanmar, Vietnam, Malaysia, Singapore, Brunei, Indonesia, East Timor, and the Philippines (where it is known as agoho pine), east to Papua New Guinea, French Polynesia, New Caledonia, and Vanuatu, and south to Australia (north of Northern Territory, north and east Queensland, and north-eastern New South Wales). Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species. The species has been introduced to the Southern United States and West Africa. It is an invasive species in Florida, South Africa, India and Brazil. Taxonomy ''Casuarina equisetifolia'' was officially described by Lin ...
