Red-headed Bullfinch
The red-headed bullfinch (''Pyrrhula erythrocephala'') is a species of finch in the family Fringillidae, found all across the Himalayas and adjacent highlands. It is found in Bhutan, northern India, Nepal and adjacent southern Tibet. Its natural habitat is temperate forest A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' ...s. Taxonomy The taxonomy was described in 2001 by Arnaiz-Villena et al. All birds belonging to the genus ''Pyrrhula'' have a common ancestor: ''Pinicola enucleator''.

Neora Valley National Park
Neora Valley National Park is a national park in Kalimpong district, West Bengal, India that was established in 1986. It spreads over an area of , and is a rich biological zone in eastern India. It is the land of the red panda in the pristine undisturbed natural habitat with rugged inaccessible hilly terrain and rich diverse flora and fauna. It is linked to Pangolakha Wildlife Sanctuary of Pakyong District as well as forests of Samtse District, Bhutan via thick cover of forests. Geography Neora Valley National Park covers an area of with an elevation of . The highest point is Rachela Danda. The forest in Neora Valley has such luxurious growth that even sunlight finds it difficult to touch the ground. Much of the park is still inaccessible, making it an adventurous place for the nature lovers/trekkers who can take the challenge to explore the still-unknown terrain in the Kalimpong district hills.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Nepal
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 ...

Pyrrhula
Pyrrhula is a small genus of passerine birds, commonly called bullfinches, belonging to the finch family (Fringillidae). The genus has a Palearctic distribution; almost all species occur in Asia, with two species exclusively in the Himalayas and one species, ''P. pyrrhula'', also occurring in Europe. The Azores bullfinch (''P. murina'') is a critically endangered species (about 120 pairs remaining), occurring only in the east of the island of São Miguel in the Azores archipelago. Analysis of the mtDNA cytochrome ''b'' sequence indicates that the Holarctic pine grosbeak (''Pinicola enucleator'') is the closest living relative of this genus. Arguably, it could be included in ''Pyrrhula'', but more probably is a distinct offshoot of a common ancestor, with the pine grosbeak as the sister group to the ancestor of the bullfinches. The evolution of the bullfinch species started soon after the pine grosbeak's ancestors diverged from them (at the end of the Middle Miocene, about 12 ...

Red-headed Bullfinch Pangolakha Wildlife Sanctuary East Sikkim Sikkim India 05
Red hair (also known as orange hair and ginger hair) is a hair color found in one to two percent of the human population, appearing with greater frequency (two to six percent) among people of Northern or Northwestern European ancestry and lesser frequency in other populations. It is most common in individuals homozygous for a recessive allele on chromosome 16 that produces an altered version of the MC1R protein. Red hair varies in hue from a deep burgundy or bright copper, or auburn, to burnt orange or red-orange to strawberry blond. Characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin, it is associated with fair skin color, lighter eye color, freckles, and sensitivity to ultraviolet light. Cultural reactions to red hair have been varied. The term "redhead" has been in use since at least 1510. Geographic distribution Modern Northern and Western Europe Red hair is most commonly found at the northern and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
