Endemic Birds Of Sri Lanka
Sri Lanka is home to 34 endemic bird species. The total number of bird species recorded in the island is 492 of which 219 are breeding residents. BirdLife International recognize Sri Lanka as one of the world's Endemic Bird Areas (EBAs). The number of endemic species has changed many times over the years. This is largely due to " close taxonomic revisions". The number of endemic species has fluctuated from a minimum 20 to a maximum 47. From 1977 the number settled at around 21. The figure was increased to 23 with the addition of two species in 1990. Many authorities have accepted this figure since then. Wijesinghe published ''A checklist of the birds of Sri Lanka'' in 1994 which considered the addition of three more species, but this move did not receive widespread recognition because its rationale was not in keeping with rigorous taxonomic practice. Subsequent publications on the avifauna of Sri Lanka and the South Asia region have not listed these three as endemics. However, wi ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka Wood Pigeon
The Sri Lanka wood pigeon (''Columba torringtoniae'') is a pigeon which is an endemic resident breeding bird in the mountains of Sri Lanka. This species nests in damp evergreen woodlands in the central highlands, building a stick nest in a tree and laying a single white egg. Its flight is quick, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. Most of its food is vegetable. Normally silent it utters an owl-like ''hoo'' call in the breeding season. The Sri Lanka wood pigeon is 36 cm in length. Its upperparts and tail are dark grey, and the head and underparts are lilac, becoming paler on the belly. There is a black-and-white chessboard pattern on the nape. This pigeon can be quite easily seen in the woods of the Horton Plains National Park. In culture In Sri Lanka, this bird is known as ''Manila Goya'' - මානිලගොයා in Sinhala Language. This wood-pigeon in a 25c Sri Lanka Sri Lanka ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbiformes
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka Junglefowl
The Sri Lankan junglefowl (''Gallus lafayettii'' sometimes spelled ''Gallus lafayetii''), also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order which is endemic (ecology), endemic to Sri Lanka, where it is the national bird. It is closely related to the red junglefowl (''G. gallus''), the wild junglefowl from which the chicken was domesticated. However, a whole-genome molecular study rather show that Sri Lankan junglefowl and grey junglefowl are genetically sister species than with the red junglefowl. Sri Lankan junglefowl and red junglefowl diverged about 2.8 million years ago, whereas time of divergence between the Sri Lankan junglefowl and grey junglefowl was 1.8 million years ago. Evidence of introgressive hybridization from Sri Lanka junglefowl has also been established in Domestic Chicken, domestic chicken. The specific name (zoology), specific name of the Sri Lankan junglefowl commemorates the French aristocrat Gilbert du M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phasianidae
The Phasianidae are a family (biology), family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, Turkey bird, turkeys, Old World quail, and peafowl. The family includes many of the most popular Game (hunting), gamebirds. The family is a large one and includes 185 species divided into 54 genera. It was formerly broken up into two subfamily (biology), subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyly, paraphyletic and polyphyly, polyphyletic, respectively, and more recent evidence supports breaking it up into two subfamilies: Rollulinae and Phasianinae, with the latter containing multiple Tribe (biology), tribes within two Clade, clades. The New World quail (Odontophoridae) and guineafowl (Numididae) were formerly sometimes included in this family, but are now typically placed in families of their own; conversely, grouse and turkey (bird), turkeys, formerly often treated as distinct families ...

Sri Lanka Spurfowl
The Sri Lanka spurfowl (''Galloperdix bicalcarata'') is a member of the pheasant family which is endemic to the dense rainforests of Sri Lanka. In Sri Lanka, this bird is known as - in Sinhala. It is a very secretive bird, and despite its size is difficult to see as it slips through dense undergrowth. Often the only indication of its presence is its distinctive ringing call, consisting of series of three-syllabled whistles. Kitulgala and Sinharaja are sites where there is a chance of seeing this bird. This spurfowl is one of three species of bird in the genus ''Galloperdix''. It is a ground nesting bird, which lays 2-5 eggs in a scrape. Sri Lanka spurfowl is ~ 37 cm long bird. Both sexes have brown upperparts, wings and tail. The males exhibit vivid crimson red legs and bare facial skin and striking black and white dorsal plumage that extends to its head. There is also extensive white ocellation on the sepia wings and upperback. The legs of both sexes have multiple m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galliformes
Galliformes is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds. The order contains about 290 species, inhabiting every continent except Antarctica, and divided into five families: Phasianidae (including chicken, quail, partridges, pheasants, turkeys, peafowl (peacocks) and grouse), Odontophoridae (New World quail), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and brush-turkeys). They adapt to most environments except for innermost deserts and perpetual ice. Many gallinaceous species are skilled runners and escape predators by running rather than flying. Males of most species are more colorful than the females, with often elaborate courtship behaviors t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
