Passeridae
Old World sparrows are a group of small passerine birds forming the family Passeridae. They are also known as true sparrows, a name also used for a particular genus of the family, ''Passer''. They are distinct from both the New World sparrows, in the family Passerellidae, and from a few other birds sharing their name, such as the Java sparrow of the family Estrildidae. Many species nest on buildings and the house and Eurasian tree sparrows, in particular, inhabit cities in large numbers. They are primarily seed-eaters, though they also consume small insects. Some species scavenge for food around cities and, like gulls or pigeons, will eat small quantities of a diversity of items. Description Generally, Old World sparrows are small, plump, brown and grey birds with short tails and stubby, powerful beaks. The differences between sparrow species can be subtle. Members of this family range in size from the chestnut sparrow (''Passer eminibey''), at and , to the parrot-billed spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Montifringilla
''Montifringilla'' is a genus of passerine birds in the sparrow family Passeridae. It is one of three genera containing the snowfinches. As the English and scientific names suggest, these are high-altitude species, found in the mountain ranges of southern Eurasia, from the Pyrenees east to the Himalayas, Tibet and western China. Description Snowfinches are stocky sparrows in length, with strong conical bills. They have pale brown upperparts, white underparts and extensive white panels in the wings, which transform them in flight. Adults may have black markings on the chin or around the eyes. Sexes are usually very similar, although the male white-winged snowfinch has a distinctive grey head. Young birds are a drabber version of the adult., , They have simple repetitive songs, given from a rock or during the elaborate circling display flight. The call is a simple ''chip'' or similar.

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 ...

Nikolai Przhevalsky
Nikolay Mikhaylovich Przhevalsky (or Prjevalsky;; pl, Nikołaj Przewalski, . – ) was a Russian geographer of Polish descent (he was born in a Polish noble family), and a renowned explorer of Central and East Asia. Although he never reached his ultimate goal, the holy city of Lhasa in Tibet, he traveled through regions then unknown to the West, such as northern Tibet (modern Tibet Autonomous Region), Amdo (now Qinghai) and Dzungaria (now northern Xinjiang). He contributed substantially to European knowledge of Central Asian geography. He also described several species previously unknown to European science: Przewalski's horse, Przewalski's gazelle, and the wild Bactrian camel, all of which are now endangered. He was a mentor of his follower Pyotr Kozlov. Biography Przhevalsky was born in Kimborovo, in the Smolensky Uyezd of the Smolensk Governorate of the Russian Empire in the Polish noble family. He studied there and at the military academy in St. Petersburg. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

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 Tibet
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] |
