Hail Haor Wildlife Sanctuary
Hail Haor Wildlife Sanctuary ( bn, হাইল হাওর বন্যপ্রাণী সংরক্ষণ অভয়ারণ্য) is a major wildlife sanctuary in Bangladesh. It is one of the most important wetlands in the Sylhet Basin for the resident and migratory waterfowls. It is also important watersource for the inhabitants living around when all other sources dry up during summer. The sanctuary is located in Moulvibazar District, in the northeast region of the country. Description The sanctuary is located mainly between the hills on the south, west and east side and Manu and Kushiara river plains on the north. The hills are covered with tea gardens and natural forest blocks. The water of the wetland extends to cover approximately during the monsoon and shrinks to during the summer season. It is restricted to 130 beels and narrow canals. There are about 172000 people living in 62 villages around the wetland. The receding water after monsoon exposes the land w ...

Moulvibazar District
Moulvibazar ( bn, মৌলভীবাজার) also spelled Maulvibazar, Moulavibazar, and Maulavibazar, (former South Sylhet) is the southeastern district of Sylhet Division in northeastern Bangladesh, named after the town of Moulvibazar. It is bordered by the Indian states of Tripura and Assam to the south and east, respectively; and by the Bangladeshi districts of Habiganj to the west and Sylhet to the north. Etymology The name of the district, Moulvibazar is named after its headquarter, Moulvibazar. The word is derived from two words, moulvi and bazar, meaning 'Market of the Moulvi'.

Cotton Pygmy Goose
The cotton pygmy goose or cotton teal (''Nettapus coromandelianus'') is a small perching duck which breeds in Asia, Southeast Asia extending south and east to Queensland where they are sometimes called white-quilled pygmy goose. They are among the smallest waterfowl in the world and are found in small to large waterbodies with good aquatic vegetation. They are usually seen in pairs or larger groups of pairs, roosting and nesting on trees near water. They are strong fliers and are known to disperse widely, especially in winter. Their breeding season coincides with the rains. Taxonomy The cotton pygmy goose 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 ducks, swans and geese in the genus ''Anas'' and coined the binomial name ''Anas coromandeliana''. Gmelin based his description on "La Sarcelle de Coromandel" that had been described in 1783 by the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teal
alt=American teal duck (male), Green-winged teal (male) Teal is a greenish-blue colour. Its name comes from that of a bird — the Eurasian teal (''Anas crecca'') — which presents a similarly coloured stripe on its head. The word is often used colloquially to refer to shades of cyan in general. It can be created by mixing cyan into a green base, or deepened as needed with black or grey. The complementary colour of teal is pink. It is also one of the first group of 16 HTML/CSS web colors formulated in 1987. In the RGB model used to create colours on computer screens and televisions, teal is created by reducing the brightness of cyan to about one half. Teal was a fad colour during the 1990s, with, among others, many sports teams adopting the colour for their uniforms. Etymology The first recorded use of ''teal'' as a colour name in English was in 1917. The term ''teal'' (referring to a sort of duck) is derived from the Middle English ''tele'', a word akin to the D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comb Duck
The comb duck or American comb duck (''Sarkidiornis sylvicola''), is an unusual duck, found in tropical wetlands in continental South America south to the Paraguay River region in eastern Paraguay, southeastern Brazil and extreme northeastern Argentina, and as a vagrant on Trinidad. Most taxonomic authorities split this species and the knob-billed duck from each other. The comb duck is generally smaller in size when compared to the knob-billed duck, and flanks are darker (black in males, medium grey in females). Description and systematics This common species is unmistakable. It is one of the largest species of duck. Length can range from , wingspan ranges from and weight from . biodiversityexplorer.org Adults have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruddy Shelduck
The ruddy shelduck (''Tadorna ferruginea''), known in India as the Brahminy duck, is a member of the family Anatidae. It is a distinctive waterfowl, in length with a wingspan of . It has orange-brown body plumage with a paler head, while the tail and the flight feathers in the wings are black, contrasting with the white wing-coverts. It is a migratory bird, wintering in the Indian subcontinent and breeding in southeastern Europe and central Asia, though there are small resident populations in North Africa. It has a loud honking call. The ruddy shelduck mostly inhabits inland water-bodies such as lakes, reservoirs and rivers. The male and female form a lasting pair bond and the nest may be well away from water, in a crevice or hole in a cliff, tree or similar site. A clutch of about eight eggs is laid and is incubated solely by the female for about four weeks. The young are cared for by both parents and fledge about eight weeks after hatching. In central and eastern Asia, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greylag Goose
The greylag goose or graylag goose (''Anser anser'') is a species of large goose in the waterfowl family Anatidae and the type species of the genus ''Anser''. It has mottled and barred grey and white plumage and an orange beak and pink legs. A large bird, it measures between in length, with an average weight of . Its distribution is widespread, with birds from the north of its range in Europe and Asia migrating southwards to spend the winter in warmer places. It is the type species of the genus ''Anser'' and is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC. The genus name is from ''anser'', the Latin for "goose". Greylag geese travel to their northerly breeding grounds in spring, nesting on moorlands, in marshes, around lakes and on coastal islands. They normally mate for life and nest on the ground among vegetation. A clutch of three to five eggs is laid; the female incubates the eggs and both parents defend and re ...

Bar-headed Goose
The bar-headed goose (''Anser indicus'') is a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India. It lays three to eight eggs at a time in a ground nest. It is known for the extreme altitudes it reaches when migrating across the Himalayas. Taxonomy The grey goose genus ''Anser'' has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus ''Eulabeia'' in 1852, though John Boyd's taxonomy treats both ''Eulabeia'' and the genus ''Chen'' as subgenera of ''Anser''. Description The bird is pale grey and is easily distinguished from any of the other grey geese of the genus ''Anser'' by the black bars on its head. It is also much paler than the other geese in this genus. In flight, its call is a typical goose honking. A mid-sized goose, it measures in total length and ...

Spotbill Duck
The Indian spot-billed duck (''Anas poecilorhyncha'') is a large dabbling duck that is a non-migratory breeding duck throughout freshwater wetlands in the Indian subcontinent. The name is derived from the red spot at the base of the bill that is found in the mainland Indian population. When in water it can be recognized from a long distance by the white tertials that form a stripe on the side, and in flight it is distinguished by the green speculum with a broad white band at the base. This species and the eastern spot-billed duck (''A. zonorhyncha'') were formerly considered conspecific, together called the spot-billed duck (''A. poecilorhyncha''). Taxonomy The Indian spot-billed duck was described by the naturalist Johann Reinhold Forster in 1781 under its current binomial name ''Anas poecilorhyncha''. The name of the genus ''Anas'' is the Latin word for a duck. The specific epithet ''poecilorhyncha'' combines the classical Greek words ''poikilos'' meaning "pied" or "spotted ...

Gadwall
The gadwall (''Mareca strepera'') is a common and widespread dabbling duck in the family Anatidae. Taxonomy The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus '' Mareca''. There are two subspecies: * ''M. s. strepera'', the common gadwall, described by Linnaeus, is the nominate subspecies. * ''M. s. couesi'', Coues's gadwall, extinct 1874, was formerly found only on Teraina, a coral atoll in the Pacific Ocean. The specific name ''strepera'' is Late Latin for "noisy". The etymology of the word ''gadwall'' is not known, but the name has been in use since 1666. Description The gadwall is long with a wingspan. The male is slightly larger than the female, weighing on average against her . The breeding male is patterned grey, with a ...

Tufted Duck
The tufted duck or tufted pochard (''Aythya fuligula'') is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and ''Latin'' ''fuligo'' "soot" and ''gula'' "throat". Description The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks. In particular, some have white around the bill base which resembles the scaup species, although the white is never as extensive as in those ducks. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo". The onl ...

Common Pochard
The common pochard (; ''Aythya ferina'') is a medium-sized diving duck. The scientific name is derived from Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ''ferina'', "wild game", from ''ferus'', "wild". Description The adult male has a long dark bill with a grey band, a red head and neck, a black breast, red eyes and a grey back. The adult female has a brown head and body and a narrower grey bill-band. The triangular head shape is distinctive. Pochards are superficially similar to the closely related North American redhead and canvasback. Females give hoarse growls. Males have whistles cut off by a final nasal note ''aaoo-oo-haa''. Distribution and habitat Their breeding habitat consists of marshes and lakes with a metre or more water depth. Pochards breed in much of temperate and northern Europe and across the Palearctic. They are migratory, and spend winter in the south and west of Europe. In the Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
