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. Distribution and status It is found in China, Pakistan, India, Nepa ... [...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 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 ...

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 ...

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 ...

Seed Predation
Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source,Hulme, P.E. and Benkman, C.W. (2002) "Granivory", pp. 132–154 in ''Plant animal Interactions: An Evolutionary Approach'', ed. C.M. Herrera and O. Pellmyr. Oxford: Blackwell. . in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates (especially mammals and birds) as well as invertebrates (mainly insects); thus, seed predation occurs in virtually all terrestrial ecosystems. Seed predation is commonly divided into two distinctive temporal categories, pre-dispersal and post-dispersal predation, which affect the fitness of the parental plant and the dispersed offspring (the seed), respectively. Mitigating pre- and post-dispersal predation may involve different strategies. To counter seed predation, plants have evolved both physical defenses ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Baltistan
Baltistan (); also known as Baltiyul or Little Tibet, is a mountainous region in the Pakistani-administered territory of Gilgit-Baltistan and constitutes a northern portion of the larger Kashmir region that has been the subject of a dispute between India and Pakistan since 1947. It is located near the Karakoram (south of K2) and borders Gilgit to the west, China's Xinjiang to the north, Indian-administered Ladakh to the southeast, and the Indian-administered Kashmir Valley to the southwest. The average altitude of the region is over . Baltistan is largely administered under the Baltistan Division. Prior to the partition of British India in 1947, Baltistan was part of the princely state of Jammu and Kashmir, having been conquered by Gulab Singh's armies in 1840. Baltistan and Ladakh were administered jointly under one ''wazarat'' (district) of the state. The region retained its identity in this setup as the Skardu ''tehsil'', with Kargil and Leh being the other two ''tehs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunza (princely State)
Hunza (, ), also known as Kanjut (; ), was a Burushaski, Burusho princely state in the present-day Gilgit-Baltistan, Gilgit Baltistan region of Pakistan. Although under the suzerainty of the Kashmir (princely state), Jammu and Kashmir (princely state), it was not a part of it and had status of a separate state. Initially, it functioned as a principality and subsequently became a princely state under a subsidiary alliance with the British India starting in 1892 and continuing until August 1947. For a brief period of three months, it remained unaligned after gaining independence, and then from November 1947 until 1974, it retained its status as a princely state within Pakistan. The territory of Hunza now constitutes the northernmost part of Gilgit-Baltistan, Pakistan. The princely state bordered the Gilgit Agency to the south, the former Nagar (princely state), princely state of Nagar to the east, Xinjiang, China, to the northeast and Afghanistan to the northwest.
