States And Territories Of India
India is a federal union comprising 28 states and 8 union territories, with a total of 36 entities. The states and union territories are further subdivided into districts and smaller administrative divisions. History Pre-independence The Indian subcontinent has been ruled by many different ethnic groups throughout its history, each instituting their own policies of administrative division in the region. The British Raj mostly retained the administrative structure of the preceding Mughal Empire. India was divided into provinces (also called Presidencies), directly governed by the British, and princely states, which were nominally controlled by a local prince or raja loyal to the British Empire, which held '' de facto'' sovereignty ( suzerainty) over the princely states. 1947–1950 Between 1947 and 1950 the territories of the princely states were politically integrated into the Indian union. Most were merged into existing provinces; others were organi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-winged Teal
The blue-winged teal (''Spatula discors'') is a species of bird in the duck, goose, and swan family Anatidae. One of the smaller members of the dabbling duck group, it occurs in North America, where it breeds from southern Alaska to Nova Scotia, and south to northern Texas. It winters along the Pacific and Atlantic coasts and south into the Caribbean islands and Central America. Taxonomy The first formal description of the blue-winged teal was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his '' Systema Naturae''. He coined the binomial name ''Anas discors''. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus ''Anas'', as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the blue-winged teal moved into the resurrected genus '' Spatula''. This genus had been originally proposed by the German zoologist Friedrich Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Jackal
The golden jackal (''Canis aureus''), also called common jackal, is a wolf-like canid that is native to Southeast Europe, Southwest Asia, South Asia, and regions of Southeast Asia. The golden jackal's coat varies in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is smaller and has shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle than the Arabian wolf. It is listed as Least Concern on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter. Despite its name, the golden jackal is not closely related to the African black-backed jackal or side-striped jackal, which are part of the genus ''Lupulella''. It is instead closer to wolves and coyotes. The ancestor of the golden jackal is believed to be the extinct Arno river dog that lived in southern Europe . It is described as having been a small, jackal-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Spoonbill
The Eurasian spoonbill (''Platalea leucorodia''), or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae. The genus name ''Platalea'' is from Latin and means "broad", referring to the distinctive shape of the bill, and ''leucorodia'' is from Ancient Greek ''leukerodios'' "spoonbill", itself derived from ''leukos'', "white" and ''erodios'' "heron". In England it was traditionally known as the "shovelard", a name later used for the Northern Shoveller. Taxonomy and systematics A study of mitochondrial DNA of the spoonbills found that the Eurasian spoonbill is sister taxon to a clade containing the royal and black-faced spoonbills. The Eurasian spoonbill has three subspecies: * ''P. l. leucorodia'' – Linnaeus, 1758: nominate, occupies all the range except as below. * ''P. l. balsaci'' – Naurois & Roux, 1974: found on the islands off the Banc d'Arguin, Mauritania. * ''P. l. archeri'' – Neumann, 1928: found on the coasts of the Red Sea ...

Painted Stork
The painted stork (''Mycteria leucocephala'') is a large wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not migratory and only make short distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring on thermals. Description This large stork has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heronry
A heronry, sometimes called a heron rookery, is a breeding ground for herons. Notable heronries Although their breeding territories are often on more protected small islands in lakes or retention ponds, herons breed in heronries (or also called rookeries, especially since other birds join them like spoonbills, storks, and cormorants). Some of the notable heronries are: Asia * Kaggaladu Heronry is in Karnataka state of India. This heronry, in the Tumkur district of Karnataka, was first made known to the outside world in 1999 by members of the Tumkur-based NGO Wildlife Aware Nature Club. Europe * |
Spot-billed Pelican
The spot-billed pelican (''Pelecanus philippensis'') or gray pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations. Taxonomy The spot-billed pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other pelicans in the genus '' Pelecanus'' and coined the binomial name ''Pelecanus philippensis''. Gmelin based his description on "Le pélican des Philippines" that had been described and illustrated in 1760 by the French z ...

Black-headed Ibis
The black-headed ibis (''Threskiornis melanocephalus''), also known as the Oriental white ibis, Indian white ibis, and black-necked ibis, is a species of wading bird of the ibis family Threskiornithidae which breeds in the South and Southeast Asia from India to the west and as far east as Japan. It is the only native ibis species in its range that has an overall white plumage with a black neck and head. The down-curved beak and legs are also black. Though often referred to as a wetland species, the black-headed ibis forages in a range of natural and man-made habitats. This species of ibis nests only during the rainy season. Description The black-headed ibis is one of several large waterbird species in south and south-east Asia, with adults measuring 65–76 cm in length. The white plumage is starkly contrasted against a conspicuous naked black neck and head, and black down-curved beak. Tails of adults bear light grey ornamental feathers that turn jet black during th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oriental Darter
The Oriental darter (''Anhinga melanogaster'') is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body is submerged in water. It spears a fish underwater, bringing it above the surface, tossing and juggling it before swallowing the fish head first. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry. Description The Oriental darter is like all other anhingas, a cormorant-like species that has a very long neck. The structure of the neck is as in other species of darter with strongly developed muscles about a kink in the neck at the 8th and 9th vertebrae that allows it to be flexed and darted forward with rapid force to stab fish underwater. ...

Greater Spotted Eagle
The greater spotted eagle (''Clanga clanga''), occasionally called the spotted eagle, is a large bird of prey. Like all typical eagles, it belongs to the family Accipitridae. Its feathered legs indicate it is a member of the subfamily Aquilinae, also known as the "booted eagles".Helbig, A. J., Kocum, A., Seibold, I., & Braun, M. J. (2005). ''A multi-gene phylogeny of aquiline eagles (Aves: Accipitriformes) reveals extensive paraphyly at the genus level''. Molecular phylogenetics and evolution, 35(1), 147-164. This species was once thought to be included in the genus '' Aquila'' but now belongs to a distinct genus, '' Clanga'', along with the other two species of spotted eagles.Helbig, A. J., Seibold, I., Kocum, A., Liebers, D., Irwin, J., Bergmanis, U., Meyburg, B.-U., Scheller, W., Stubbe, M. & Bensch, S. (2005).

Acacia Nilotica
''Vachellia nilotica'', more commonly known as ''Acacia nilotica'', and by the vernacular names of gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia, is a flowering tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a ' weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States. Taxonomy This species of tree is the type species of the Linnaean genus ''Acacia'', which derives its name from grc, ἀκακία, ', the name given by early Greek botanist-physician Pedanius Dioscorides (ca. 40–90) to this tree as a medicinal, in his book '' Materia Medica''. The genus ''Acacia'' was long known not to be taxonomically monophyletic, and despite being the type species of that genus, ''A. nilotica'' has since been moved to the genus '' Vachellia'', with the genus name ''Acacia'' being reserved for Au ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.
