Caucasian Great Rosefinch
The great rosefinch (''Carpodacus rubicilla'') is a species of finch in the family Fringillidae. It is found in Afghanistan, Azerbaijan, Georgia, Iran, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Russia, Tajikistan, and Uzbekistan and east to China. Its natural habitats are tundra and temperate grassland A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur natur .... While past taxonomies treated ''C. r. severtzovi'' and two other subspecies as a separate species, the spotted great rosefinch (and called the nominate subspecies the "Caucasian great rosefinch"), they now usually considered subspecies of the great rosefinch. Four subspecies are recognised: *''C. r. rubicilla'' (Caucasian great rosefinch) - ( Güldenstädt, 1775) - central and eastern Caucasus Mountains * ''C. r. diabolicus' ...

North Sikkim
North Sikkim (now officially named as Mangan District) is a list of Indian districts, district of the Indian states and territories of India, state of Sikkim. Its district headquarters is Mangan, India, Mangan. It is the seventh least populous district in the country (out of Districts of India, 640). Geography The district is the largest of the four districts of Sikkim. The landscape is mountainous with dense vegetation all the way up to the alpine altitude before thinning out to desert scrub towards the northern tundra. Numerous waterfalls astride the main road make the trip to this district extremely picturesque. The most prominent effect of the steepness of the valleys is the prevalence of landslides that at times drop to anything between 3000 and carrying devastation along their course. Most of them are caused either by the melting snow beds on top of the mountains or by erosive action of the rains. Most of the people of the state reside near Mangan, the district head ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ...

Birds Described In 1775
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 ...

Carpodacus
The rosefinches are a genus, ''Carpodacus'', of passerine birds in the finch family Fringillidae. Most are called "rosefinches" and as the word implies, have various shades of red in their plumage. The common rosefinch is frequently called the "rosefinch". The genus name is from the Ancient Greek terms ''karpos'', "fruit", and ''dakno'', "to bite". The ''Carpodacus'' rosefinches occur throughout Eurasia, but the greatest diversity is found in the Sino-Himalayas suggesting that the species originated in this region. Systematics In 2012, Zuccon and colleagues published a comprehensive molecular phylogenetic analysis of the finch family. Based both on their own results and those published earlier by other groups, they proposed a series of changes to the taxonomy. They found that the three North American rosefinches, namely Cassin's finch, purple finch, and house finch, formed a separate clade that was not closely related to the Palearctic rosefinches. They proposed moving the thr ...

Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Poeoptera sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow of the headmaster at Gramm ...
