Birds Of Thailand
The birds of Thailand included 1093 species as of 2022. Of them, 7 have been introduced by humans, and eight have been extirpated. The birds of Thailand are mainly typical of the Indomalayan realm, with affinities to the Indian subcontinent to the west, and, particularly in Southern Thailand, with the Sundaic fauna to the southeast. The northern mountains are outliers of the Tibetan Plateau, with many species of montane birds, and in winter the avifauna is augmented by migrants from the eastern Palearctic and Himalayas. That Thailand's habitats are contiguous with those of neighbouring countries explains the low number of endemic species. In 1991, it was estimated that 159 resident and 23 migratory species were endangered or vulnerable due to forest clearance, illegal logging, hunting and habitat degradation, especially in the lowlands. The species most affected are large water birds whose wetland habitat has been largely lost to agriculture, and forest species, as deforestati ...

Anseriformes
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

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, pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knob-billed Duck
The knob-billed duck (''Sarkidiornis melanotos''), or African comb duck, is a duck found in tropical wetlands in Sub-Saharan Africa, Madagascar and the Indian Subcontinent from northern India to Laos and extreme southern China. Most taxonomic authorities split this species and the comb duck from each other. The supposed extinct "Mauritian comb duck" is based on misidentified remains of the Mauritius sheldgoose (''Alopochen mauritiana''); this was realized as early as 1897, but the mistaken identity can still occasionally be found in recent sources. 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 . biodiver ...

Lesser White-fronted Goose
The lesser white-fronted goose (''Anser erythropus'') is a goose closely related to the larger white-fronted goose (''A. albifrons''). It breeds in the northernmost Palearctic, but it is a scarce breeder in Europe. There is a re-introduction scheme in Fennoscandia. The scientific name comes from ''anser'', the Latin for "goose", and ''erythropus'', "red-footed", derived from the old Greek ''eruthros'' "red" and ''pous'' "foot". The lesser white-fronted goose winters further south in Europe and is a rare winter vagrant to Great Britain and India. Individual birds formerly appeared regularly at WWT Slimbridge in Gloucestershire, England, where they inspired Sir Peter Scott to set up The Wildfowl and Wetlands Trust—modern records, however, are far less frequent, a consequence of the species' decline on its European breeding grounds. An attractive species, it is also widely kept in wildfowl collections and, as a result, escapes do occur; individuals seen in summer, or in the company ...

Greater White-fronted Goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose related to the smaller lesser white-fronted goose (''A. erythropus''). It is named for the patch of white feathers bordering the base of its bill, in fact ''albifrons ''comes from the Latin ''albus'' "white" and ''frons "''forehead". In Europe it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. Description Greater white-fronted geese are in length, have a wingspan, and weigh . They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swan Goose
The swan goose (''Anser cygnoides'') is a large goose with a natural breeding range in inland Mongolia, northernmost China, and the Russian Far East. It is migratory and winters mainly in central and eastern China. Vagrant birds are encountered in Japan and Korea (where it used to winter in numbers when it was more common), and more rarely in Kazakhstan, Laos, coastal Siberia, Taiwan, Thailand and Uzbekistan. While uncommon in the wild, this species has been domesticated. Introduced and feral populations of its domestic breeds occur in many places outside its natural range. The wild form is also kept in collections, and escapes are not unusual amongst feral flocks of other ''Anser'' and ''Branta'' geese. Description The swan goose is large and long-necked for its genus, wild birds being long (the longest ''Anser'' goose) and weighing or more (the second-heaviest ''Anser'', after the greylag goose, ''A. anser''). The sexes are similar, although the male is larger, with a prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graylag 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 rear ...

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 w ...

Lesser Whistling-duck
The lesser whistling duck (''Dendrocygna javanica''), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump. Description This chestnut brown duck is confusable only with the fulvous whistling duck (''D. bicolor'') but has chestnut upper-tail coverts unlike the creamy white in the latter. The ring around the eye is orange to yellow. When flying straight, their head is held below the level of the body as in other ''Dendrocygna'' species. The crown appears dark and ...

Cotton Pgymy Goose I2- Kolkata IMG 4808
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back t ...

Swan
Swans are birds of the family (biology), family Anatidae within the genus ''Cygnus''. The swans' closest relatives include the goose, geese and ducks. Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe (biology), tribe Cygnini. Sometimes, they are considered a distinct subfamily, Cygninae. There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life, although "divorce" sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another. The number of bird egg, eggs in each :wikt:clutch, clutch ranges from three to eight. Etymology and terminology The English word ''swan'', akin to the German language, German , Dutch language, Dutch and Swedish language, Swedish , is derived from Indo-European root ' ('to sound, to sing'). Young swans are kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
