Chatham Bellbird
The Chatham bellbird (''Anthornis melanocephala'') is an extinct species of bird in the family Meliphagidae. It was endemic to the Chatham Islands. In appearance it was very similar to the New Zealand bellbird (''Anthornis melanura'') but was considerably larger. Also the whole of the head and neck was brightly glossed in purplish or steel-blue. by , 1888 It was last observed in 1906 on Little Mangere Island

George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''.

Anthornis
''Anthornis'' is a bird genus in the honeyeater family (Meliphagidae). Its members are called bellbirds. According to genetic data, it is a sister genus to '' Prosthemadera.'' It contains the following species: * New Zealand bellbird The New Zealand bellbird (''Anthornis melanura''), also known by its Māori names korimako, makomako, and kōmako, is a passerine bird endemic to New Zealand. It has greenish colouration and is the only living member of the genus ''Anthornis''. T ..., ''Anthornis melanura'' * Chatham bellbird, ''Anthornis melanocephala'' (extinct) They are named bellbirds because their call sounds like a bell. Young male bellbirds copy the calls of neighbouring older males. Sometimes two males can sing in almost perfect unison because one has been copying the other.

Species Endangered By Invasive Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Extinct Birds Of The Chatham Islands
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] |
Little Mangere Island
Little Mangere is a small island of the Chatham Archipelago, just off the western end of Mangere Island, about 4 km (2½ mi) west of Pitt Island and south-east of the town of Waitangi on Chatham Island. The island is called ''Tapuaenuku'' in Moriori and Māori, and was formerly called The Fort.Government of New Zealand, Dept. of Conservation (1999) Chatham IslandsConservation Management Strategy', map 6. Accessed on 2012-07-13. The archipelago is part of New Zealand and is located about to the east of the South Island. Little Mangere has less than . It has a relatively flat interior surrounded by steep cliffs, and its highest point is above sea level. Little Mangere is privately owned and was once the last refuge of the few remaining Black robin until they were transferred to nearby Mangere Island and South East Island as part of a species recovery plan in the early 1980s. The island still hosts the largest sooty shearwater ('' Puffinus griseus'') colony in the Chatha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Walter Buller
Sir Walter Lawry Buller (9 October 1838 – 19 July 1906) was a New Zealand lawyer and naturalist who was a dominant figure in New Zealand ornithology. His book, ''A History of the Birds of New Zealand'', first published in 1873, was published as an enlarged version in 1888 and became a New Zealand classic. Biography Buller was born at Newark, the Wesleyan mission at Pakanae in the Hokianga, the son of Rev. James Buller, a Cornish missionary who had helped convert the people of Tonga to Methodism. He was educated at Wesley College in Auckland. In 1854, he moved to Wellington with his parents, where he was befriended by the naturalist William John Swainson. In 1859 he was made Native Commissioner for the Southern Provinces. In 1871 he travelled to England and was called to the bar at the Inner Temple. Three years later he returned to Wellington and practised law. In 1862, he married Charlotte Mair at Whangārei. They were to have four children. Buller was the author of '' ...
