Ground Jay
The ground jays or ground choughs belong to a distinct group of the passerine order of birds in the genus ''Podoces'' of the crow family Corvidae. They inhabit high altitude semi-desert areas from central Asia to Mongolia. Ground jays show adaptations to ground living such as long, strong legs adapted to fast running and the ability to leap and bound onto boulders and rocks with great agility. Their long, curved thick bills are adapted for digging and probing. While capable of flight (which they do infrequently and relatively weakly), they prefer running, and will readily perch on trees and bushes also. Species list The ground tit (''Pseudopodoces humilis''), previously Hume's ground jay, has changed its placement within the Passeriformes recently because of molecular and osteological testing. It has now been placed into the Paridae The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphe ...

Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

Passeriformes
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.

Ground Tit
The ground tit, Tibetan ground-tit or Hume's ground-tit (''Pseudopodoces humilis'') is a bird of the Tibetan plateau north of the Himalayas. The peculiar appearance confused ornithologists in the past who called it as Hume's groundpecker and still later as Hume's ground jay or Tibetan ground jay assuming that it belonged to the family (biology), family Corvidae that includes the crows and jays. Although morphologically confusing, the species has since been identified using molecular sequence comparisons as being a member of the tit (bird), tit family (Paridae) and is the only species in the genus ''Pseudopodoces''.James ''et al.'' (2003), del Hoyo ''et al.'' (2007) It is found in the Tibetan Plateau of China, India, Nepal & Bhutan. Description ''Pseudopodoces'' is somewhat similar in appearance to the unrelated ground jays (''Podoces'') but much smaller – about the size of a house sparrow (''Passer domesticus'') – and lacks any conspicuous markings.

Turkestan Ground-Jay
The Turkestan ground jay, grey ground jay or Pander's ground-jay (''Podoces panderi'') is a species of bird in the crow and jay family, Corvidae. It is found in central Asia, particularly Kazakhstan, Turkmenistan, and Uzbekistan. More specifically, they tend to be found in Astragalus, Calligonum and southern Salsola vegetation zones. It is closely related to the Iranian ground jay. Its natural habitat is sandy desert with low shrub cover. It also forages around human settlements and roads.

Mongolian Ground Jay (Podoces Hendersoni) - Хулан жороо (16566349299)
The Mongolian ground jay (''Podoces hendersoni'') or Henderson's ground jay, is a species of bird in the family Corvidae. Description The bird is light tan with iridescent blue on its primary feathers. It has a long, curved beak and a black stripe on its forehead. Distribution It is found in arid areas of Central Asia (Mongolia, northern China and adjacent areas of Russia and Kazakhstan). Behaviour Females spend more time foraging and the males spend more time brooding the chicks at the start of the nesting period. The main diet of the nestling Mongolian ground jay consists of common lizards, toad-headed agama, and invertebrates. It is proposed that Mongolian ground jays feed their chicks based on the availability of their food rather than in relation to the stage of the chicks development.

Bird Flight
Bird flight is the primary mode of locomotion used by most bird species in which birds take off and fly. Flight assists birds with feeding, breeding, avoiding predators, and migrating. Bird flight is one of the most complex forms of locomotion in the animal kingdom. Each facet of this type of motion, including hovering, taking off, and landing, involves many complex movements. As different bird species adapted over millions of years through evolution for specific environments, prey, predators, and other needs, they developed specializations in their wings, and acquired different forms of flight. Various theories exist about how bird flight evolved, including flight from falling or gliding (the ''trees down'' hypothesis), from running or leaping (the ''ground up'' hypothesis), from ''wing-assisted incline running'' or from '' proavis'' (pouncing) behavior. Basic mechanics of bird flight Lift, Drag and Thrust The fundamentals of bird flight are similar to those of aircraft, in ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...
