Mandal
A tehsil (, also known as tahsil, taluka, or taluk) is a local unit of administrative division in some countries of South Asia. It is a subdistrict of the area within a district including the designated populated place that serves as its administrative centre, with possible additional towns, and usually a number of villages. The terms in India have replaced earlier terms, such as '' pargana'' (''pergunnah'') and ''thana''. In Andhra Pradesh and Telangana, a newer unit called mandal (circle) has come to replace the system of tehsils. It is generally smaller than a tehsil, and is meant for facilitating local self-government in the panchayat system. In West Bengal, Bihar, Jharkhand, community development blocks are the empowered grassroots administrative unit, replacing tehsils. As an entity of local government, the tehsil office (panchayat samiti) exercises certain fiscal and administrative power over the villages and municipalities within its jurisdiction. It is the ultimate execu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulicat Lake
Pulicat Lagoon is the second largest brackish water lagoon in India, (after Chilika Lake), measuring . Major part of the lagoon comes under Tirupati district of Andhra Pradesh. The lagoon is one of the three important wetlands to attract northeast monsoon rain clouds during the October to December season. The lagoon comprises the following regions, which adds up according to Andhra Pradesh Forest Department: 1) Pulicat Lake (Tamil Nadu-TN & Andhra Pradesh-AP) 2) Marshy/Wetland Land Region (AP) 3) Venadu Reserve Forest (AP) 4) Pernadu Reserve Forest (AP) The lagoon was cut across in the middle by the Sriharikota Link Road, which divided the water body into lagoon and marshy land. The lagoon encompasses the Pulicat Lake Bird Sanctuary. The barrier island of Sriharikota separates the lagoon from the Bay of Bengal and is home to the Satish Dhawan Space Centre. History In the 1st century, the anonymous mariner who wrote ''Periplus of the Erythraean Sea'' listed Podouke (Pulicat) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seagulls
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...

Common Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small ''Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Shovelers
The northern shoveler (; ''Spatula clypeata''), known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon. The northern shoveler is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. The conservation status of this bird is Least Concern. Taxonomy The northern shoveler was first formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He introduced the binomial name ''Anas clypeata''. A molecular phylogentic study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-winged Stilts
The black-winged stilt (''Himantopus himantopus'') is a widely distributed very long-legged wader in the avocet and stilt family (Recurvirostridae). The scientific name ''H. himantopus'' is sometimes applied to a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of ''Himantopus himantopus'' ''sensu lato'' (whereas the black-necked, ''H. mexicanus'', and white-backed stilt, ''H. melanurus'', both inhabit the Americas, and the pied stilt, ''H. leucocephalus'', inhabit southeast Asia to Australia and New Zealand). Most sources today accept 1–4 species. The scientific name ''Himantopus'' comes from the Greek meaning "strap foot" or "thong foot". Description Adults are long. They have long pink legs, a long thin black bill and are blackish above and white below, with a white head and neck with a varying amount of black. Males have a black back, often with greenish gloss.

Northern Pintails
The pintail or northern pintail (''Anas acuta'') is a duck species with wide geographic distribution that breeds in the northern areas of Europe and across the Palearctic and North America. It is migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage. The drake also has attractive grey, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. Hens make a coarse q ...

Grey Herons
The grey heron (''Ardea cinerea'') is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Palearctic, Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts bird migration, migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows. Standing up to tall, adults weigh from . They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown. The birds breed Colony (biology), colonially in spring in "heronries", usually building their nests high in trees. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Pelicans
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 ...

Large Egrets
The great egret (''Ardea alba''), also known as the common egret, large egret, or (in the Old World) great white egret or great white heron is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently it is also spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water. Taxonomy and systematics Like all egrets, it is a member of the heron family, Ardeidae. Traditionally classified with the storks in the Ciconiiformes, the Ardeidae are closer relatives of pelicans and belong in the Pelecaniformes, instead. The great egret—unlike the typical egrets—does not belong to the genus ''Egretta'', but together with the great herons is today placed in '' Ardea''. In the past, however, it was sometimes placed in ''Egretta'' or separated in a monotypic genus ''Casmerodius''. The Old World population is ...

Painted Storks
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 a he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
