Wetar Ground-dove
The Wetar ground dove (''Pampusana hoedtii'') is a species of bird in the family Columbidae found on Wetar, Indonesia, and on Timor. Its natural habitats are monsoon forests and gallery forests, and possibly woodland and bamboos. Threatened by habitat loss and hunting, the species is assessed as endangered by the IUCN. Taxonomy In 1871, Hermann Schlegel described the species as ''Leptoptila hoedtii'' from Wetar. The species is monotypic. It has been moved from the genus '' Gallicolumba'' to ''Alopecoenas'' Sharpe, 1899. The name of the genus was changed in 2019 to ''Pampusana'' Bonaparte, 1855 as this name has priority. The specific epithet is derived from Dirk Samuel Hoedt, a Dutch collector who owned plantations in the East Indies. Description Body length is about long. The male bird has a blue-grey head and a greyish white throat. The breast is pale cream, and the belly is blackish. The hindneck is reddish brown. The back and rump are rufous. Tail feathers are dar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Indies
The East Indies (or simply the Indies), is a term used in historical narratives of the Age of Discovery. The Indies refers to various lands in the East or the Eastern hemisphere, particularly the islands and mainlands found in and around the Indian Ocean by Portuguese explorers, soon after the Cape route was discovered. Nowadays, this term is broadly used to refer to the Malay Archipelago, which today comprises the Philippine Archipelago, Indonesian Archipelago, Malaysian Borneo, and New Guinea. Historically, the term was used in the Age of Discovery to refer to the coasts of the landmasses comprising the Indian subcontinent and the Indochinese Peninsula along with the Malay Archipelago. Overview During the era of European colonization, territories of the Spanish Empire in Asia were known as the Spanish East Indies for 333 years before the American conquest. Dutch occupied colonies in the area were known for about 300 years as the Dutch East Indies till Indonesian indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Endangered By Habitat Loss
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 zoologica ...

Birds Described In 1871
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. Birds ...

Endangered Biota Of Asia
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) IUCN Red List, 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 Environmental law, laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create Protected area, 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.
