Yellow-billed Pintail
The yellow-billed pintail (''Anas georgica'') is a South American dabbling duck of the genus ''Anas'' with three described subspecies. Taxonomy The yellow-billed pintail 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 with all the ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas georgica''. Gmelin based his description on the "Georgia duck" that had been described in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the duck by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. The watercolour was painted in 1775 on South Georgia. This picture is now the holotype for the species and is held by the Natural History Museum in London. The genus name ''Anas'' is the Latin wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural History Museum, London
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domina ...

Yellow-billed Teal
The yellow-billed teal (''Anas flavirostris'') is a South American species of duck. Like other teals, it belongs to the diverse genus ''Anas''; more precisely it is one of the "true" teals of subgenus ''Nettion''. It occurs in Argentina, the Falkland Islands, Chile, Peru, Bolivia, Uruguay, and Brazil. It has also established itself in South Georgia, where it was first recorded breeding in 1971, and has been recorded as far east as Tristan da Cunha. It inhabits freshwater wetlands, preferring palustrine habitat to rivers. Considering its wide range and local abundance, it is not considered threatened by the IUCN. Description The namesake bill is bright yellow with a black tip and a black band along the ridge of the culmen. The species is somewhat similar to the larger yellow-billed pintail, but has a darker head, shorter neck and plain grayish sides. Taxonomy Mitochondrial DNA sequence data is most similar to that of the very different-looking green-winged teal.Johnson & So ...

Niceforo's Pintail
Niceforo's pintail (''Anas georgica niceforoi'') is an extinct subspecies of the yellow-billed pintail (''Anas georgica''), a duck in the dabbling duck subfamily Anatinae The Anatinae are a subfamily of the family Anatidae (swans, geese and ducks). Its surviving members are the dabbling ducks, which feed mainly at the surface rather than by diving. The other members of the Anatinae are the extinct moa-nalo, a youn .... One of three subspecies, it was found in central Colombia but became extinct in the 1950s, being last seen in 1952. Description Niceforo's pintail was darker and richer in colouration than the nearest other subspecies, the Chilean pintail ''A. g. spinicauda'', with the head and neck more streaked, the crown dark brown and with a less pointed tail. Distribution The former range of included subtropical and temperate zones of north-central Colombia, 1000–3000 m above sea level in the upper Cauca Valley, the central part of the Cordillera Oriental, the Bogota ...

Chilean Pintail
The Chilean pintail (''Anas georgica spinicauda''), also known as the golden peck duck or brown pintail, is a subspecies of the yellow-billed pintail (''Anas georgica''), a duck in the dabbling duck subfamily Anatinae. Its local names are ''pato jergón grande'', ''pato maicero'' and ''pato piquidorado'' in Spanish, and ''marreca-parda'' or ''marreca-danada'' in Portuguese. Distribution and habitat The Chilean pintail is one of three subspecies of the yellow-billed pintail, and by far the most numerous and widespread. It is found throughout much of South America from extreme southern Colombia southwards to Tierra del Fuego, as well as in the Falkland Islands. The two other subspecies are the smaller South Georgia pintail which is limited to the subantarctic island of South Georgia and which is sometimes considered a separate species, and the extinct Niceforo's pintail, which occurred formerly in central Colombia. Chilean pintails inhabit freshwater lakes, rivers, marshes, lagoons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Georgia Pintail
The South Georgia pintail (''Anas georgica georgica''), also misleadingly known as the South Georgian teal, is the nominate subspecies of the yellow-billed pintail (''Anas georgica''), a duck in the dabbling duck subfamily Anatinae. It is endemic to the large (3,756 km2) subantarctic island of South Georgia and its accompanying archipelago, and is a vagrant to the South Sandwich Islands. It was among the birds noted by James Cook in January 1775, on the occasion of the first recorded landing on South Georgia, and was formerly considered a full species. Taxonomy The duck has long been recognised as a distinct taxon, with its affinities previously considered to be with the teals. Robert Cushman Murphy was the first to demonstrate that it is a pintail, its closest relatives the yellow-billed pintails of South America (now split as the Chilean pintail ''A. g. spinicauda'' and the extinct Niceforo's pintail ''A. g. niceforoi''),Murphy (1916). though he retained it as a full ...

South Georgia Island
South Georgia ( es, Isla San Pedro) is an island in the South Atlantic Ocean that is part of the British Overseas Territory of South Georgia and the South Sandwich Islands. It lies around east of the Falkland Islands. Stretching in the east–west direction, South Georgia is around long and has a maximum width of . The terrain is mountainous, with the central ridge rising to at Mount Paget. The northern coast is indented with numerous bays and fjords, serving as good harbours. Discovered by Europeans in 1675, South Georgia had no indigenous population due to its harsh climate and remoteness. Captain James Cook in made the first landing, survey and mapping of the island, and on 17 January 1775 he claimed it a British possession, naming it "Isle of Georgia" after King George III. Through its history, it served as a whaling and seal hunting base, with intermittent population scattered in several whaling bases, the most important historically being Grytviken.

Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Falkland Islands
The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833, but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands. British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...
