Raiatea Parakeet
The Raiatea parakeet or Society parakeet (''Cyanoramphus ulietanus''), also known as the Society kakariki or brown-headed parakeet, is an extinct parakeet of the genus ''Cyanoramphus''. Description The Raiatea parakeet averaged 25 cm (9.75 to 10 inches) in length. Its head was chocolate brown, paler on the neck, rump, and wings. The bill showed a pale bluish grey hue and had a black tip. The lower back and tail coverts exhibited a rufous brown colouring. The underwing coverts and outer webs to flight feathers were greyish blue. The breast, abdomen, and undertail coverts were olive yellow. The mid-rectrices were olive brown and outer rectrices grey. The irises were orange red in adults and brown in juveniles. The feet were greyish brown. Males and females were not sexually dimorphic. Distribution and habitat The Raiatea parakeet was endemic to Raiatea, the second largest island of the Society Islands. It was probably a forest species, as this was the native habitat on this ...

James Greenway
James Cowan Greenway (April 7, 1903 – June 10, 1989) was an American ornithologist. An eccentric, shy, and often reclusive man, his survey of extinct and vanishing birds provided the base for much subsequent work on bird conservation. Early years Greenway was born in New York City, though grew up on the Lauder Greenway Estate in Greenwich, Connecticut, with his brothers G. Lauder Greenway and Gilbert Greenway, as the son of James Greenway Sr., founder of the Yale School of Public Health.

Bird Extinctions Since 1500
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Taxa Named By Johann Friedrich Gmelin
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...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 ...

Joseph Banks
Sir Joseph Banks, 1st Baronet, (19 June 1820) was an English naturalist, botanist, and patron of the natural sciences. Banks made his name on the 1766 natural-history expedition to Newfoundland and Labrador. He took part in Captain James Cook's first great voyage (1768–1771), visiting Brazil, Tahiti, and after 6 months in New Zealand, Australia, returning to immediate fame. He held the position of president of the Royal Society for over 41 years. He advised King George III on the Royal Botanic Gardens, Kew, and by sending botanists around the world to collect plants, he made Kew the world's leading botanical garden. He is credited for bringing 30,000 plant specimens home with him; amongst them, he was the first European to document 1,400. Banks advocated British settlement in New South Wales and the colonisation of Australia, as well as the establishment of Botany Bay as a place for the reception of convicts, and advised the British government on all Australian matte ...

James Cook
James Cook (7 November 1728 Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the siege of Quebec, which brought him to the attention of the Admiralty and the Royal Society. This acclaim came at a crucial moment for the direction of British overseas exploration, and it led to his commission in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erwin Stresemann
Erwin Friedrich Theodor Stresemann (22 November 1889, in Dresden – 20 November 1972, in East Berlin) was a German naturalist and ornithologist. Stresemann was an ornithologist of extensive breadth who compiled one of the first and most comprehensive accounts of avian biology of its time as part of the ''Handbuch der Zoologie'' (Handbook of Zoology). In the process of his studies on birds, he also produced one of the most extensive historical accounts on the development of the science of ornithology. He influenced numerous ornithologists around him and oversaw the development of ornithology in Germany as editor of the ''Journal für Ornithologie''. He also took an interest in poetry, philosophy and linguistics. He published a monograph on the Paulohi language based on studies made during his ornithological expedition to the Indonesian island. Early life Stresemann was born in Dresden to Richard, an apothecary and Marie. His grandfather Theodor owned the ''Zum Roten Adler'' phar ...

Otto Finsch
Friedrich Hermann Otto Finsch (8 August 1839, Warmbrunn – 31 January 1917, Braunschweig) was a German ethnographer, natural history, naturalist and colonial explorer. He is known for a two-volume monograph on the parrots of the world which earned him a doctorate. He also wrote on the people of New Guinea and was involved in plans for German colonization in Southeast Asia. Several species of bird (such as ''Oenanthe finschii'', ''Alophoixus finschii'', ''Psittacula finschii'') are named after him as also the town of Finschhafen in Morobe Province, Papua New Guinea and a crater on the moon. Biography Finsch was born at Cieplice Śląskie-Zdrój, Bad Warmbrunn in Silesia to Mortiz Finsch and Mathilde née Leder. His father was in the glass trade and he too trained as a glass painter. An interest in birds led him to use his artistic skills for the purpose. Finsch went to Budapest in 1857 and studied at the Eötvös Loránd University, Royal Hungarian University, earning money by prep ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...
