Daito Varied Tit
The Daito varied tit is an extinct subspecies of the varied tit. It was formerly found on Kita Daitō-jima and Minami Daitō-jima in the Daitō group east of the Okinawa Islands, but became extinct around 1940. It seems that the last specimens collected were Kuroda's types taken in 1922, and that the last confirmed sighting was in 1938. Searches in the 1980s and subsequently failed to find any. The subspecies became extinct following the habitat destruction brought about by settlement and construction activity in the 1930s. It differed from the typical ''P. v. varius'' in having a broad chestnut-coloured band on the upper mantle, olive-green (not dark grey) lower mantle, and orangey (not white) sides to the head (Harrap & Quinn 1996, del Hoyo et al. 2007). Like many bird taxa from the Okinawa region, the scientific name is named after the veteran specimen collector Hyojiri Orii. References *del Hoyo, J., Elliot, A., & Christie D. (eds). (2007).

Taxa Named By Nagamichi Kuroda
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and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu.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 int ... [...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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poecile
''Poecile'' is a genus of birds in the tit family Paridae. It contains 15 species, which are scattered across North America, Europe and Asia; the North American species are the chickadees. In the past, most authorities retained ''Poecile'' as a subgenus within the genus ''Parus'', but treatment as a distinct genus, initiated by the American Ornithologists Union, is now widely accepted. This is supported by mtDNA cytochrome ''b'' sequence analysis. The genus ''Poecile'' was erected by the German naturalist Johann Jakob Kaup in 1829. The type species was subsequently designated as the marsh tit (''Poecile palustris'') by English zoologist George Robert Gray in 1842. The name ''Poecile'' is from Ancient Greek ''poikilos'' "colourful". A related word ''poikilidos'' denoted an unidentified small bird. It has traditionally been treated as feminine (giving name endings such as ''cincta''); however, this was not specified by the original genus author Johann Jakob Kaup, and under the ...

Bulletin Of The British Ornithologists' Club
The ''Bulletin of the British Ornithologists' Club'' is an ornithological journal published by the British Ornithologists' Club (BOC). It is cited as ''Bull. B. O. C.'' Many descriptions of birds new to science have been published in the bulletin. The journal was first published in 1892. It is published in four quarterly issues. from March 2017 (Vol. 137 No. 1), it became an online-only, open access, journal, giving as the reasons for the change: Since 2004, the journal's honorary editor has been Guy Kirwan.

Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned specia ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Type
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost ...

Okinawa Islands
The Okinawa Islands ( or ) are an island group in Okinawa Prefecture, Japan and are the principal island group of the prefecture. The Okinawa Islands are part of the larger Ryukyu Islands group and are located between the Amami Islands of Kagoshima Prefecture to the northeast and the Sakishima Islands of Okinawa Prefecture to the southwest. The Okinawa Islands, apart from the main island, contain three smaller island groups: the Kerama, Yokatsu and Iheya-Izena island groups. The Okinawa Islands are the political, cultural and population center of Okinawa Prefecture. The prefectural capital of Naha is within the island group. 90% of the population of the prefecture reside within the Okinawa Islands, primarily on the largest island of the group, Okinawa Island. Access to the various Okinawa Islands is primarily via small airports which connect to Naha Airport. Additionally, the islands are connected via ferry service to the Port of Naha in the prefectural capital. The Okinaw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
