Pagan Reed Warbler
The Pagan reed warbler (''Acrocephalus yamashinae'') was sometimes considered a subspecies of the nightingale reed warbler. It originally occurred on Pagan Island Pagan is a volcanic island in the Marianas archipelago in the northwest Pacific Ocean, under the jurisdiction of the Commonwealth of the Northern Mariana Islands. It lies midway between Alamagan to the south, and Agrihan to the north. The islan ... and "was extinct by the late 1970s". More precisely, in the 1970s, the 1980s, in 2000 and in 2010, the bird could not be found and is therefore presumed to be extinct.

Nightingale Reed Warbler
The nightingale reed warbler (''Acrocephalus luscinius''), or Guam reed-warbler, was a songbird endemic to Guam. It has not been seen since 1969. Taxonomy and systematics The nightingale reed warbler was described by the French zoologists Jean Quoy and Joseph Gaimard in 1832 from a specimen collected on the island of Guam in the western Pacific Ocean. They coined the binomial name, ''Thryothorus luscinius''. Until 2011, the Pagan reed warbler, Aguiguan reed warbler, and Saipan reed warbler were considered as subspecies of the nightingale reed warbler until split by the IOC. Threats The nightingale reed warbler was driven to extinction by several introduced species. These included the brown tree snake which has also decimated the populations of several other bird species on Guam. Other introduced predators included rats, cats and feral ungulates such as goats or sheep. An introduced plant, ivy gourd ''Coccinia grandis'', the ivy gourd, also known as scarlet gourd, ...

Pagan Island
Pagan is a volcanic island in the Marianas archipelago in the northwest Pacific Ocean, under the jurisdiction of the Commonwealth of the Northern Mariana Islands. It lies midway between Alamagan to the south, and Agrihan to the north. The island has been largely uninhabited ever since most of the residents were evacuated due to volcanic eruptions in 1981. History Archaeological finds indicate that Pagan was settled from several centuries BC. The first European contact was in 1669, when the island was sighted by the Spanish missionary Diego Luis de San Vitores who named it ''San Ignacio'' ( Saint Ignatius in Spanish). It is likely that it was previously visited in 1522 by the Spanish sailor Gonzalo de Vigo, deserter from the Magellan expedition in 1521, and the first European castaway in the history of the Pacific. The native Chamorro population was forcibly deported to Saipan in 1695, and then three years later to Guam. The Chamorros began to return to Pagan in the early 19th ...

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 ...

Birds Of The Northern Mariana Islands
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] |
Extinct Birds Of Oceania
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, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
