The smew (''Mergellus albellus'') is a species of duck, and is the only living member of the genus ''Mergellus''. ''Mergellus'' is a diminutive of '' Mergus'' and ''albellus'' is from Latin ''albus'' "white". This genus is closely related to ''Mergus'' and is sometimes included in it, though it might be closer to the goldeneyes (''Bucephala''). The smew has hybridized with the common goldeneye (''B. clangula''). A seaduck fossil from the Middle Miocene shows that birds similar to smew existed up to 13 million years ago. The extant species dates back to the Late Pleistocene. Name The term ''smew'' has been used since the 17th century and is of uncertain origin. It is believed to be related to the Dutch ''smient'' ("wigeon") and the German ''Schmeiente'' or '' Schmünte'', "wild duck." It is probably derived from ''smee'', a dialectal term for a wild duck. Description The drake smew, with its 'cracked ice' or 'panda' appearance, is unmistakable, and looks very black-and- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prideaux John Selby
Prideaux John Selby FRSE FLS (23 July 1788 – 27 March 1867) was an English ornithologist, botanist and natural history artist. Life Selby was born in Bondgate Street in Alnwick in Northumberland, the eldest son of George Selby of Beal and Twizell (d.1804), and his wife, Margaret Cook. He was educated at Durham School. He studied at University College, Oxford. He succeeded in 1804 to the family estates at Beal, and added to the landholdings there at a cost of some £14000 in about 1840. He sold the Beal estate amounting to in 1850 for £47000 (£ at today's prices). He died at Twizell House and was buried in Bamburgh churchyard. Family In 1810 he married Lewis Tabitha Mitford (1782–1859) daughter of Bertram Osbaldeston Mitford (1748–1800) of Dennet's Hall in Leicester. They had three daughters. Work Selby is best known for his ''Illustrations of British Ornithology'' (1821–1834), the first set of life-sized illustrations of British birds. He also wrote ''Ill ...

Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (formerly known as Middle Pleistocene) and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period (Marine Isotope Stage 5). It is held to end with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological ...

Yakutia
Sakha, officially the Republic of Sakha (Yakutia),, is the largest republic of Russia, located in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million. Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers (1,190,555 sq mi).

Bird Genera
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. Bi ...

Taxa Named By Prideaux John Selby
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
