Pale-backed Pigeon
The yellow-eyed pigeon, pale-backed pigeon, yellow-eyed dove or yellow-eyed stock dove (''Columba eversmanni'') is a member of the family Columbidae (doves and pigeons). It breeds in southern Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan, Kyrgyzstan, Afghanistan, north-east Iran and extreme north-west China. It winters in north-east Pakistan, Jammu and Kashmir (union territory), Jammu and Kashmir and parts of Rajasthan (including Tal Chhapar Sanctuary and Jorbeer, Bikaner). The bird has declined in numbers over the years, chiefly because of hunting, and it is listed as "Vulnerable species, vulnerable" by the International Union for Conservation of Nature. The bird was Species description, first described by the French ornithologist Charles Lucien Bonaparte in 1856. The binomial commemorates the German biologist and explorer Eduard Friedrich Eversmann who did much research into the flora and fauna of the southeast steppes of Russia.

Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857) was a French naturalist and ornithology, ornithologist, and a nephew of Napoleon. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte (cardinal), Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I of France, Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde Laetitia Julie Bonaparte, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a Old World warbler, warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new Wilson's storm-petrel ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

Birds Of Western China
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 furth ...

Columba (genus)
The bird genus ''Columba'' comprises a genus of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. ''Columba'' species are mostly termed "pigeons", and in many cases "wood pigeons", but some (including the type species of the genus), are termed "doves". The rock dove (''C. livia'') has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon, some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon (''C. palumbus''). This genus as understood today is native to the Old World, but some (notably the domestic and feral rock dove) have been introduced outside their natural range, for example in the Americas. Etymology The term ''columba'' comes from the Latin ''columba'', "a dove", the feminine form of ''columbus'', "a male dove", itself the latinisation of the Greek κόλυμβος (''kolumbos''), "dive ...

Morus (plant)
''Morus'', a genus of flowering plants in the family Moraceae, consists of 19 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 subordinate taxa, though the three most common are referred to as white, red, and black, originating from the color of their dormant buds and not necessarily the fruit color (''Morus alba'', '' M. rubra'', and '' M. nigra'', respectively), with numerous cultivars and some taxa currently unchecked and awaiting taxonomic scrutiny. ''M. alba'' is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. ''M. alba'' is also the species most preferred by the silkworm. It is regarded as an invasive species in Brazil, the United States and some states of Australia. The closely related genus '' Broussonetia'' is also commonly known as mulberry, notably the paper mulberry (''Brousso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the tropical and subtropical grasslands, savannas, and shrublands biome * the temperate grasslands, savannas, and shrublands biome A steppe is usually covered with grass and shrubs, depending on the season and latitude. The term ''steppe climate'' denotes a semi-arid climate, which is encountered in regions too dry to support a forest, but not dry enough to be a desert. Steppes are usually characterized by a semi-arid or continental climate. Temperature extremes can be recorded in the summer of up to and in winter of down to . Besides this major seasonal difference, fluctuations between day and night are also significant: in both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night.

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Hill Pigeon
The hill pigeon (''Columba rupestris'') is a species of bird in the family Columbidae. Other names include eastern rock dove and Turkestan hill dove. Description The hill pigeon is a stout-bodied pigeon, similar in size and general appearance to the rock dove (''Columba livia'') but mainly differentiated by its tail pattern which consists 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 (''Columba leuconota''), but lacks the contrast between the head and neck in that species. Taxonomy and systematics Two subspecies are accepted: * ''C. r. rupestris'', described by Pallas in 1811, is found in the northeastern part of the species' distribution. * ''C. r. turkestanica'', described by Buturlin in 1908, is found in the southwestern part of the species' distribution.

Rock Dove
The rock dove (''Columba livia''), also sometimes known as "rock pigeon" or "common pigeon", is a member of the bird family Columbidae (doves and pigeons). In common usage, it is often simply referred to as the "pigeon", although the rock dove is the wildlife, wild form of the bird; the pigeons familiar to most people are the domesticated forms of the wild rock dove. Wild rock doves are uniformly pale grey with two black bars on each wing, with few differences being seen between males and females; i.e. they are not strongly sexually dimorphic. The domestic pigeon (often, but invalidly, called "''Columba livia domestica''"), which includes about List of pigeon breeds, 1,000 different breeds, is descended from this species. Escaped domestic pigeons are the origin of feral pigeons around the world. Both forms can Domestic pigeon#Markings, vary widely in the colour and pattern of their plumage unlike their wild ancestor, being red, brown, checkered, uniformly coloured, or pied. H ...
