White-capped Water Redstart
The white-capped redstart or white-capped water redstart (''Phoenicurus leucocephalus'') is a passerine bird of the Old World flycatcher family Muscicapidae native to the Indian Subcontinent,Southeast Asia, much of China, and to certain regions of Central Asia. Description Both sexes are black with red underparts and white crown atop their heads. Males have a larger white pattern on top of the head and brown or red spots under the wings. It is found in the Indian Subcontinent and Southeast Asia, as well as some adjoining areas. The species ranges across Afghanistan, Bangladesh, Bhutan, Cambodia, India, Laos, Myanmar, Nepal, Tajikistan, Thailand, Tibet and Vietnam. Its natural habitat is temperate forests. This species was formerly placed in the monotypic genus ''Chaimarrornis'' but was moved to ''Phoenicurus'' based on the results of a molecular phylogenetic study published in 2010.

Nicholas Aylward Vigors
Nicholas Aylward Vigors (1785 – 26 October 1840) was an Ireland, Irish zoologist and politician. He popularized the classification of birds on the basis of the quinarian system. Early life Vigors was born at Old Leighlin, County Carlow, in 1785. He was the first son of Capt. Nicholas Aylward Vigors, who served in the 29th (Worcestershire) Regiment of Foot, 29th (Worcestershire) Regiment, and his first wife, Catherine Vigors, daughter of Solomon Richards of Solsborough. He matriculated at Trinity College, Oxford, in November 1803, and was admitted at Lincoln's Inn in November 1806. Without completing his studies, he served in the army during the Peninsular War from 1809 to 1811 and was wounded in the Battle of Barrosa, Battle of Barossa on 5 March 1811. Though he had not yet completed his studies, he still published "An inquiry into the nature and extent of poetick licence" in London in 1810. He then returned to Oxford to continue his studies and achieved his Bachelor of Arts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibet
Tibet (; ''Böd''; ), or Greater Tibet, is a region in the western part of East Asia, covering much of the Tibetan Plateau and spanning about . It is the homeland of the Tibetan people. Also resident on the plateau are other ethnic groups such as Mongols, Monpa people, Monpa, Tamang people, Tamang, Qiang people, Qiang, Sherpa people, Sherpa, Lhoba people, Lhoba, and since the 20th century Han Chinese and Hui people, Hui. Tibet is the highest region on Earth, with an average elevation of . Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth's highest mountain, rising above sea level. The Tibetan Empire emerged in the 7th century. At its height in the 9th century, the Tibetan Empire extended far beyond the Tibetan Plateau, from the Tarim Basin and Pamirs in the west, to Yunnan and Bengal in the southeast. It then divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a ser ...

More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Birds Of The Himalayas
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur (''Semnopithecus schistaceus'') Lowland forests On the Indo-Gangetic plain at the base of the mountains, an alluvial plain drained by the Indus and Ganges-Brahmaputra river systems, vegetation varies from west to east with rainfall. The deserts and xeric shrublands, xeric Northwestern thorn scrub forests occupy the plains of Punjab, Pakistan, Pakistani and the Punjab, India, Indian Punjab. Further east lie the Upper Gangetic Plains moist deciduous forests of Uttarakhand and Uttar Pradesh and the Lower Gangetic Plains moist deciduous forests of Bi ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Phoenicurus
''Phoenicurus'' is a genus of passerine birds in the Old World flycatcher family Muscicapidae, native to Europe, Asia and Africa. They are named redstarts from their orange-red tails ('start' is an old name for a tail). They are small insectivores, the males mostly brightly coloured in various combinations of red, blue, white, and black, the females light brown with a red tail. A molecular phylogenetic study published in 2010 led to a reorganization of the Old World flycatchers family in which the two species in ''Rhyacornis'' and the single species in ''Chaimarrornis'' were merged into ''Phoenicurus''. The genus ''Phoenicurus'' was introduced by the English naturalist Thomas Forster in 1817. The type species (by tautonymy) is the common redstart (''Phoenicurus phoenicurus''). The name ''Phoenicurus'' is from Ancient Greek φοινιξ (''phoinix''), "(Phoenician) crimson/purple" (see also Tyrian purple), and ουροσ (''-ouros'') -"tailed".. The genus contains the fol ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...
