Birds Of Sri Lanka
Sri Lanka is a tropical island situated close to the southern tip of India. The bird life of Sri Lanka is very rich for its size and more than 500 species have been recorded. In addition to the many resident birds, a considerable number of bird migration, migratory species winter in the country to escape their northern breeding grounds. 35 species are confirmed as endemic (ecology), endemic, the latest addition being the Sri Lanka shama, which previously considered as a subspecies of the white-rumped shama. The other resident species are also found in the nearby Indian mainland, but over 80 have developed distinct Sri Lankan races. Some of these races are very different in their plumage characteristics from the related forms in India. 26 species are globally threatened. Bird distribution in Sri Lanka is largely determined by its climatic zones. The dry zone is largest of the three, covering more than half of the island, with a prolonged dry and hot period and only one monsoon (the ...

Sri Lanka
Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, also known historically as Ceylon, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, separated from the Indian subcontinent, Indian peninsula by the Gulf of Mannar and the Palk Strait. It shares a maritime border with the Maldives in the southwest and India in the northwest. Sri Jayawardenepura Kotte is the legislative capital of Sri Lanka, while the largest city, Colombo, is the administrative and judicial capital which is the nation's political, financial and cultural centre. Kandy is the second-largest urban area and also the capital of the last native kingdom of Sri Lanka. The most spoken language Sinhala language, Sinhala, is spoken by the majority of the population (approximately 17 million). Tamil language, Tamil is also spoken by approximately five million people, making it the second most-spoken language in Sri Lanka. Sri Lanka has a population of appr ...

Duck
Duck is the common name for numerous species of waterfowl in the family (biology), family Anatidae. Ducks are generally smaller and shorter-necked than swans and goose, geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch language, Dutch and German language, German 'to dive'. This word replaced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruddy Shelduck
The ruddy shelduck (''Tadorna ferruginea''), known in India as the Brahminy duck, is a bird species in 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 As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarkidiornis Melanotos - Royal Museum For Central Africa - DSC06799
''Sarkidiornis'' is a genus within the family Anatidae comprising two species that inhabit aquatic environments in tropical and subtropical regions of South America, Africa and southern Asia.. ''Sarkidiornis'' is sometimes considered a monotypic genus with its sole member the knob-billed duck (''S. melanotos''), a cosmopolitan species. Taxonomy This genus was first described in 1838 by Thomas Campbell Eyton. The type species, ''Anser melanotos'' (''S. melanotos''), was originally described in 1769 by Thomas Pennant, based on a bird collected in what is now Sri Lanka Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, also known historically as Ceylon, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, separated from the Indian subcontinent, .... Etymologically, the term Sarkidiornis is derived from Greek, where sarkidion means "little meat" or "caruncle", and ornis means "bird". This name refers to the fl ...

Knob-billed Duck
The knob-billed duck (''Sarkidiornis melanotos'') or African comb duck is a type of duck found along the tropical/sub-tropical wetlands and waterways of Sub-Saharan Africa and the island of Madagascar, as well as most of South Asia and mainland Indochina. Most taxonomic authorities classify the knob-billed duck and the comb duck separately. A misidentified species of extinct Mauritian comb duck was initially described from unrecognised remains of the Mauritius sheldgoose (''Alopochen mauritiana''); this was realised as early as 1897, but the printed case of mistaken identity can still, occasionally, be found in modern-day sources. Taxonomy and systematics Uncertainty surrounds the correct systematic placement of this species. Initially, it was placed in the dabbling duck subfamily Anatinae. Later, it was assigned to the "perching ducks", a paraphyletic assemblage of waterfowl most of which are intermediate between dabbling ducks and shelducks. As the "perching ducks" were split ...

Greylag Goose - St James's Park, London - Nov 2006
The greylag 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 often migrating southwards to spend the winter in warmer places, although many populations are resident, even in the north. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BCE. The genus name and specific epithet are from ''anser'', the Latin for "goose". In the USA, its name has been spelled "graylag". 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 eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 bar-headed goose is basal in the grey goose genus '' Anser''. The genus ''Anser'' has only one other member indigenous to the Indian region (greylag goose of the subspecies ''Anser anser rubrirostris'', which also winters in the region), and none to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus ''Eulabeia'' in 1852, though other authorities treat both ''Eulabeia'' and the genus ''Chen'' as synonyms 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 otherwise white h ...

Dendrocygna Javanica - Chiang Mai
The whistling ducks or tree ducks are a subfamily, Dendrocygninae, of the duck, goose and swan family of birds, Anatidae. In other taxonomic schemes, they are considered a separate family, Dendrocygnidae. Some taxonomists list only one genus, ''Dendrocygna'', which contains eight living species, and one undescribed extinct species from Aitutaki of the Cook Islands, but other taxonomists also list the white-backed duck (''Thalassornis leuconotus'') under the subfamily. Taxonomy and evolution Whistling ducks were first described by Carl Linnaeus in the 10th edition of ''Systema Naturae'' in 1758: the black-bellied whistling duck (then ''Anas autumnalis'') and the West Indian whistling duck (then ''Anas arborea''). In 1837, William Swainson named the genus ''Dendrocygna'' to distinguish whistling ducks from the other waterfowl. The type species was listed as the wandering whistling duck (''D. arcuata''), formerly named by Thomas Horsfield as ''Anas arcuata''. Whistling ...

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 covert feather, 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 ...

Fulvous Whistling Duck
The fulvous whistling duck or fulvous tree duck (''Dendrocygna bicolor'') is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields. The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents conti ...
