Bismarck Thicketbird
The New Britain thicketbird or Bismarck thicketbird (''Cincloramphus grosvenori'') is a bird species. It used to be placed in the "Old World warbler" family Sylviidae, but it does not seem to be a close relative of the typical warblers; probably it belongs in the grass warbler family Locustellidae. It is found only in the rarely visited highlands of the island of New Britain in Papua New Guinea. This little-known species was for long classified as a data deficient species by the IUCN, due to the general lack of reliable data on its distribution and numbers. While there have been no records since its discovery in 1959, recent evidence suggests the habitat destruction in the Bismarck Archipelago presents a greater risk than previously believed, leading to the Bismarck thicketbird being listed as a Vulnerable species in the 2008 red list.BLI (2008) It used to be considered conspecific with the Santo thicketbird and the Bougainville thicketbird.

Ernest Thomas Gilliard
Ernest Thomas Gilliard (23 November 1912 – 26 January 1965) was an American ornithologist and museum curator who led or participated in several ornithological expeditions, especially to South America and New Guinea. Gilliard was born in York, Pennsylvania. He began a lifelong association with the American Museum of Natural History (AMNH) in New York in 1932 by working there as a volunteer. In 1933 he was employed there as an assistant and subsequently passed through the full range of promotions to become Curator of Birds in 1963, unexpectedly dying in office two years later, in his 53rd year, of a sudden heart attack. During the 1930s Gilliard was involved in expeditions to Quebec, Newfoundland and Venezuela, and in the 1940s to Brazil, the Philippines and New Guinea. The 1950s saw more expeditions, not only to New Guinea, but also to Nepal and the West Indies. New Guinea, and especially its birds-of-paradise and bowerbirds, kept drawing him back, and he led a total of five exped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Birds Described In 1960
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cincloramphus
''Cincloramphus'' is a genus of birds in the grassbird family Locustellidae. The genus ''Cincloramphus'' was introduced by the English ornithologist and bird artist John Gould in 1838 with the brown songlark as the type species. The name combines the Ancient Greek ''kinklos'' meaning "thrush" with ''rhamphos'' meaning "bill". A comprehensive molecular phylogenetic study of the family Locustellidae published in 2018 found that many of the genera were non-monophyletic. In the resulting reorganization the genera ''Megalurulus'' and ''Buettikoferella'' became junior synonyms of the resurrected genus ''Cincloramphus''. The genus now contains 12 species: * Brown songlark (''Cincloramphus cruralis'') * Rufous songlark (''Cincloramphus mathewsi'') * Rusty thicketbird (''Cincloramphus rubiginosus'') * New Britain thicketbird (''Cincloramphus grosvenori'') * Buff-banded thicketbird (''Cincloramphus bivittatus'') * Papuan grassbird (''Cincloramphus macrurus'') * Tawny grassbird ('' ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Bismarck Archipelago
The Bismarck Archipelago (, ) is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about 50,000 square km. History The first inhabitants of the archipelago arrived around 30–40,000 years ago. They may have traveled from New Guinea, by boat across the Bismarck Sea or via a temporary land bridge, created by an uplift in the Earth's Crust (geology), crust. Later arrivals included the Lapita people. The first European to visit these islands was Dutch explorer Willem Schouten in 1616. The islands remained unsettled by western Europeans until they were annexed as part of the German protectorate of German New Guinea in 1884. The area was named in honour of the Chancellor of Germany (German Reich), Chancellor Otto von Bismarck. On 1888 Ritter Island eruption and tsunami, 13 March 1888, a volcano erupted on Ritter Island causing a megatsunami. Almost the entire volcano fell into t ...
