Eiao Marquesan Warbler
The Eiao Marquesan warbler (''Acrocephalus percernis aquilonis'') is a subspecies of the northern Marquesan reed warbler found only in the dry upland forest on Eiao in the northern Marquesas Islands. The species comprises several different races, each of which occupies a variety of forest or bushland habitats. Because of extensive habitat destruction by feral goats, sheep and pigs, the subspecies is endangered, and may very well be extinct. The total population was estimated at approximately 100-200 individuals in 1987.

Robert Cushman Murphy
The whaling ship, ''Daisy'', which Murphy traveled on to the Antarctic Robert Cushman Murphy (April 29, 1887 – March 20, 1973) was an American ornithologist and Lamont Curator of birds at the American Museum of Natural History. He went on numerous oceanic expeditions and was an expert on marine birds, and wrote several major books on them. He described a species of petrel which is now known as Murphy's petrel. Mount Murphy in Antarctica and Murphy Wall in South Georgia are named after him. Life and work Murphy was born in Brooklyn, New York, to Thomas D. Murphy and Augusta Cushman. Around 1906 Murphy assisted Frank Chapman at the American Museum of Natural History and read the proofs of ''Warblers of North America''. He was an undergraduate at Brown University, where he graduated in 1911. He married Grace Alice Bairstow in 1911 who he met as a student at Brown University. Grace persuaded Robert to take a position as naturalist aboard the whaling ship ''Daisy''. After their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Robert Cushman Murphy
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] |
Birds Described In 1928
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 ...

Acrocephalus (bird)
The ''Acrocephalus'' warblers are small, insectivorous passerine birds belonging to the genus ''Acrocephalus''. Formerly in the paraphyletic Old World warbler assemblage, they are now separated as the namesake of the marsh and tree warbler family Acrocephalidae. They are sometimes called marsh warblers or reed warblers, but this invites confusion with marsh warbler and reed warbler proper, especially in North America, where it is common to use lower case for bird species. These are rather drab brownish warblers usually associated with marshes or other wetlands. Some are streaked, others plain. Many species breeding in temperate regions are migratory. This genus has heavily diversified into many species throughout islands across the tropical Pacific. This in turn has led to many of the resulting insular endemic species to become endangered. Several of these species (including all but one of the species endemic to the Marianas and two endemic to French Polynesia) have already go ...

Marquesas Zoology
The Marquesas Islands have a diverse aquatic zoology, and a rather limited endemic terrestrial zoology. Ocean fauna Unlike most of the warm-water islands of the South Pacific, the Marquesas are not protected by coral reefs, and therefore do not have the wide array of reef denizens found in neighboring archipelagos such as the Tuamotus and Society Islands. The one exception to this is the island of Motu One in the extreme north of the group, which is a small atoll, and the only low island in the Marquesas. Aside from Motu One, coral growths are found in several protected bays, especially on the northern and western sides of several of the islands, especially on Nuku Hiva. Sharks are common in the offshore waters. Seabirds Nineteen species of seabirds breed in the Marquesas, and a number of other species visit the islands, including: * Sternidae – terns ** Black noddy (''Anous minutus'') ** Blue-grey noddy (''Procelsterna cerulea'') ** Brown noddy (''Anous stolidus'') ...

Eiao Island Nature Reserve
The Eiao Nature Reserve is a nature reserve encompassing the whole of the island of Eiao in the northern Marquesas Islands, as well as several surrounding rocks. The reserve was declared in 1971, as a first step in preserving whatever remains of the devastated ecosystem, which has almost entirely been destroyed through over-grazing by feral goats, sheep and swine. The reserve is the primary nesting site of several endangered species, several of which are endemic, including the Eiao Marquesan warbler (''Acrocephalus mendanae aquilonis'') and the Iphis monarch (''Pomarea iphis'').

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...
