Snow Pigeon
The snow pigeon (''Columba leuconota'') is a species of bird in the genus ''Columba'' in the family Columbidae from hilly regions of central Asia. They are grey, black, pale brown and white birds and two subspecies are recognised: ''C. l. leuconota'' occurs in the western Himalayas from western Afghanistan to Sikkim and ''C. l. gradaria'' occurs in the mountains of eastern Tibet and from eastern Nan Shan (Qinghai) to Yunnan and extreme northern Myanmar. The birds forage in open country in pairs or small groups, feeding on grain, buds, shoots, berries and seeds. They roost at night on cliffs, breeding in crevices where they build untidy stick nests and lay a clutch of usually two white eggs. The International Union for Conservation of Nature has rated the bird's conservation status as being of least concern. Description Snow pigeons have a blackish head contrasting with a white neck collar and white underparts shading into ashy on the abdomen. Their backs are brownish-grey with ...

Sikkim
Sikkim (; ) is a state in Northeastern India. It borders the Tibet Autonomous Region of China in the north and northeast, Bhutan in the east, Province No. 1 of Nepal in the west and West Bengal in the south. Sikkim is also close to the Siliguri Corridor, which borders Bangladesh. Sikkim is the least populous and second smallest among the Indian states. Situated in the Eastern Himalaya, Sikkim is notable for its biodiversity, including alpine and subtropical climates, as well as being a host to Kangchenjunga, the highest peak in India and third highest on Earth. Sikkim's capital and largest city is Gangtok. Almost 35% of the state is covered by Khangchendzonga National Park – a UNESCO World Heritage Site. The Kingdom of Sikkim was founded by the Namgyal dynasty in the 17th century. It was ruled by Buddhist priest-kings known as the Chogyal. It became a princely state of British India in 1890. Following Indian independence, Sikkim continued its protectorate status with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Central Asia
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. Bird ...

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 ...

Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...

Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''.

Snow Pigeon Flock Flying Pangolakha WLS Sikkim India 11
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Dove
The rock dove, rock pigeon, or common pigeon ( also ; ''Columba livia'') is a member of the bird family Columbidae (doves and pigeons). In common usage, it is often simply referred to as the "pigeon". The domestic pigeon (''Columba livia domestica'', which includes about 1,000 different breeds) descended from this species. Escaped domestic pigeons have increased the populations of feral pigeons around the world. Wild rock doves are pale grey with two black bars on each wing, whereas domestic and feral pigeons vary in colour and pattern. Few differences are seen between males and females. The species is generally monogamous, with two squabs (young) per brood. Both parents care for the young for a time. Habitats include various open and semi-open environments. Cliffs and rock ledges are used for roosting and breeding in the wild. Originally found wild in Europe, North Africa, and western Asia, pigeons have become established in cities around the world. The species is abundant, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hill Pigeon
The hill pigeon, eastern rock dove, or Turkestan hill dove (''Columba rupestris'') is a species of bird in the family Columbidae. Description The hill pigeon is a stout-bodied pigeon, similar in size and general appearance to the rock dove but mainly differentiated by its tail pattern which consist of a broad, white tail-band across the black tail. Other differences include a paler mantle and upper wings and a white patch on the back. In flight, the tail pattern is similar to the snow pigeon, but lacks the contrast between the head and neck in that species. Taxonomy and systematics Two subspecies are recognized: * The blue hill pigeon (''C. r. rupestris''), described by Pallas, is found in the eastern range of the species' distribution. * The Turkestan hill pigeon (''C. r. turkestanica''), described by Buturlin, is found in the western range of the species' distribution.
