Sandy Island And Low Rock Important Bird Area
The Sandy Island and Low Rock Important Bird Area comprises two small islands with a collective area of 9 ha lying at the western end of the Gulf of Carpentaria in the Northern Territory of Australia. They lie south-west of Groote Eylandt off the coast of Arnhem Land, with the nearest settlement there the Numbulwar community. They are important as breeding sites for terns. Description Sandy Island consists of three islets, connected by strips of sand and exposed reef at low tide, about 20 km from the mainland. The central island, vegetated with grass, vines and shrubs, supports the main colony. Low Rock is a sand, coral rubble and rock island 25 km away, and about 30 km from the mainland; it is surrounded by a reef and has a central stand of mangroves. Both islands are traditionally owned Aboriginal land. Sea turtles nest on the islands' beaches.BirdLife International. (2011).

Important Bird Areas Of The Northern Territory
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Lesser Crested Tern
The lesser crested tern (''Thalasseus bengalensis'')Bridge, E. S.; Jones, A. W. & Baker, A. J. (2005)A phylogenetic framework for the terns (Sternini) inferred from mtDNA sequences: implications for taxonomy and plumage evolution. ''Molecular Phylogenetics and Evolution'' 35: 459–469. is a tern in the family Laridae. Etymology The genus name is from Ancient Greek ''Thalasseus'', "fisherman" from ''thalassa'', "sea". The specific ''bengalensis'' means "of Bengal", the type locality, historically referring to much of northern India and Bangladesh. Distribution It breeds in subtropical coastal parts of the world mainly from the Red Sea across the Indian Ocean to the western Pacific, and Australia, with a significant population on the southern coast of the Mediterranean on two islands off the Libyan coast. Accidental breeding has also been reported in Italy and France. The Australian birds are probably sedentary, but other populations are migratory, wintering south to South Afr ...

Black-naped Tern
The black-naped tern (''Sterna sumatrana'') is an oceanic tern mostly found in tropical and subtropical areas of the Pacific and Indian Oceans. It is rarely found inland. Description The tern is about 30 cm long with a wing length of 21–23 cm. Their beaks and legs are black, but the tips of their bills are yellow. They have long forked tails. The black-naped tern has a white face and breast with a grayish-white back and wings. The first couple of their primary feathers are gray. There are two listed subspecies: *''S. s. mathewsi'' ( Stresemann, 1914) – islands of the western Indian Ocean *''S. s. sumatrana'' ( Raffles, 1822) – islands of the eastern Indian Ocean through to the western Pacific & Australasia References External links Kiru Dhooni black-naped tern Birds of the Maldives Birds of Seychelles Birds of Southeast Asia Birds of Oceania black-naped tern The black-naped tern (''Sterna sumatrana'') is an oceanic tern mostly found in tropic ...

Bridled Tern
The bridled tern (''Onychoprion anaethetus'') is a seabird of the family Laridae. It is a bird of the tropical oceans. The scientific name is from Ancient Greek. The genus comes from ' meaning "claw" or "nail", and , meaning "saw". The specific ''anaethetus'' means "senseless, stupid". Description This is a medium-sized tern, at 30–32 cm in length and with a 77–81 cm wingspan similar to the common tern in size, but more heavily built. The wings and deeply forked tail are long, and it has dark grey upperparts and white underparts. The forehead and eyebrows are white, as is a striking collar on the hindneck. It has black legs and bill. Juvenile bridled terns are scaly grey above and pale below. This species is unlikely to be confused with any tern apart from the similarly dark-backed sooty tern and the spectacled tern from the Tropical Pacific. It is paler-backed than that sooty, (but not as pale as the grey-backed) and has a narrower white forehead and a pale neck ...

Pied Cormorant
The Australian pied cormorant (''Phalacrocorax varius''), also known as the pied cormorant, pied shag, or great pied cormorant, is a medium-sized member of the cormorant family. It is found around the coasts of Australasia. In New Zealand, it is usually known either as the pied shag or by its Māori name of . Older sources may refer to it as the "yellow-faced cormorant". Taxonomy The Australian pied cormorant was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus varius''. Gmelin based his description on the "pied shag" from Queen Charlotte Sound, New Zealand, that had been described in 1785 by English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had based his own description on a specimen in the Leverian Museum and on a watercolour by Georg Forster that belo ...

Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is the most common gull of Australia. It has been found throughout the continent, but particularly at or near coastal areas. It is smaller than the Pacific gull (''Larus pacificus''), which also lives in Australia. The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages (scientific name ''Larus argentatus'', German ''Silbermöwe'', French ''Goéland argenté'', Dutch ''zilvermeeuw''), but is a much larger, robust gull with no overlap in range. Taxonomy It has traditionally been placed in the genus ''Larus'', as is the case with many gulls, but is now placed in the genus ''Chroicocephalus''. Hartlaub's gull (''C. hartlaubii'') of South Africa was formerly sometimes considered to be subspecies of the silver gull. There are three subspecies: * ''C. n. forsteri'' ( Mathews, 1912) – north and northeast Australia, New Caledonia, Loyalty Islands * ''C. n. novaehollan ...

Greater Crested Tern
The greater crested tern Retrieved 28 February 2012 (''Thalasseus bergii''), also called crested tern or swift tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to the royal and lesser crested terns, but can be distinguished by its size and bill colour. The greater crested tern has grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter. Its young have a distinctive appearance, with strongly patterned grey, brown and white plumage, and rely on their parents for food for several months after they have fledged. Like all members of the genus ''Thalasseus'', the greater crested tern feeds by plunge diving for fish, usually in marine en ...

Roseate Tern
The roseate tern (''Sterna dougallii'') is a species of tern in the family Laridae. The genus name ''Sterna'' is derived from Old English "stearn", "tern", and the specific ''dougallii'' refers to Scottish physician and collector Dr Peter McDougall (1777–1814). "Roseate" refers to the bird's pink breast in breeding plumage. Taxonomy English naturalist George Montagu described the roseate tern in 1813. Genetically, it is most closely related to the white-fronted tern (''S. striata''), with their common ancestor a sister lineage to the black-naped tern (''S. sumatrana''). This species has a number of geographical races, differing mainly in bill colour and minor plumage details. ''S. d. dougallii '' breeds on the Atlantic coasts of Europe and North America, and winters south to the Caribbean and west Africa. Both the European and North American populations have been in long term decline, though active conservation measures have reversed the decline in the last few years at som ...

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] |
Sea Turtle
Sea turtles (superfamily Chelonioidea), sometimes called marine turtles, are reptiles of the order Testudines and of the suborder Cryptodira. The seven existing species of sea turtles are the flatback, green, hawksbill, leatherback, loggerhead, Kemp's ridley, and olive ridley sea turtles. All six of the sea turtle species present in US waters (all of those listed above except the flatback) are listed as endangered and/or threatened under the Endangered Species Act. The seventh sea turtle species is the flatback, which exists in the waters of Australia, Papua New Guinea and Indonesia. Sea turtles can be separated into the categories of hard-shelled (cheloniid) and leathery-shelled ( dermochelyid).Wyneken, J. 2001. The Anatomy of Sea Turtles. U.S Department of Commerce NOAA Technical Memorandum NMFS-SEFSC-470, 1-172 pp. There is only one dermochelyid species which is the leatherback sea turtle.
