Ashy-headed Laughingthrush (Garrulax Cinereifrons)
The ashy-headed laughingthrush (''Argya cinereifrons'') is a member of the family Leiothrichidae. The laughingthrushes are a large family of Old World passerine birds characterised by soft fluffy plumage. These are birds of tropical areas, with the greatest variety in southeast Asia. Taxonomy The ashy-headed laughingthrush was formerly placed in the genus ''Garrulax'' but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus ''Argya''. Description The ashy-headed laughingthrush is a rangy bird, 23 centimetre (9 in) in length with a long floppy tail. It is rufous brown above and deep buff below, with a grey head and white throat. Like other babblers, these are noisy birds, and the characteristic laughing calls are often the best indication that they are present, since they are often difficult to see in their preferred habitat. Distribution and habitat The ashy-headed laughingthrush is a resident breeding bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinharaja Forest Reserve
Sinharaja Forest Reserve is a forest reserve and a biodiversity hotspot in Sri Lanka. It is of international significance and has been designated a Biosphere Reserve and World Heritage Site by UNESCO. According to International Union for Conservation of Nature (IUCN), Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. 50% of Sri Lankan's endemics species of animals (especially butterfly, amphibians, birds, snakes and fish species). It is home to 95% endemic birds. The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1988. Because of the dense vegetation, wildlife is not as easily seen as at dry-zone national parks such as Yala. There are about 3 elephants, and 15 or so leopards. The most common l ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1847
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

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 ...

Rupee
Rupee is the common name for the currencies of India, Mauritius, Nepal, Pakistan, Seychelles, and Sri Lanka, and of former currencies of Afghanistan, Bahrain, Kuwait, Oman, the United Arab Emirates (as the Gulf rupee), British East Africa, Burma, German East Africa (as Rupie/Rupien), and Tibet. In Indonesia and the Maldives, the unit of currency is known as ''rupiah'' and ''rufiyaa'' respectively, cognates of the word rupee. The Indian rupees () and Pakistani rupees () are subdivided into one hundred paise (singular ''paisa'') or pice. The Nepalese rupee (रू) subdivides into one hundred paisa (singular and plural) or four sukaas. The Mauritian, Seychellois, and Sri Lankan rupees subdivide into 100 cents. Etymology The Hindustani word ''rupyā'' is derived from the Sanskrit word ''rūpya'' (), which means "wrought silver, a coin of silver", in origin an adjective meaning "shapely", with a more specific meaning of "stamped, impressed", whence "coin". It is derived f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinhala Language
Sinhala ( ; , ''siṁhala'', ), sometimes called Sinhalese (), is an Indo-Aryan languages, Indo-Aryan language primarily spoken by the Sinhalese people of Sri Lanka, who make up the largest ethnic group on the island, numbering about 16 million. Sinhala is also spoken as the first language by other ethnic groups in Sri Lanka, totalling about 2 million people as of 2001. It is written using the Sinhala script, which is a Brahmic scripts, Brahmic script closely related to the Grantha script of South India. Sinhala is one of the official and national languages of Sri Lanka. Along with Pali, it played a major role in the development of Theravada, Theravada Buddhist literature. The early form of the Sinhala language, is attested as early as the 3rd century BCE. The language of these inscriptions with long vowels and aspirated consonants is a Prakrit similar to Magadhi, a regional associate of the Middle Indian Prakrits that has been used during the time of the Buddha.

Old World Babbler
The Old World babblers or Timaliidae are a family of mostly Old World passerine birds. They are rather diverse in size and coloration, but are characterised by soft fluffy plumage. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The timaliids are one of two unrelated groups of birds known as babblers, the other being the Australasian babblers of the family Pomatostomidae (also known as pseudo-babblers). Morphological diversity is rather high; most species resemble "warblers", jays or thrushes. This group is among those Old World bird families with the highest number of species still being discovered. Characteristics Timaliids are small to medium birds. They have strong legs, and many are quite terrestrial. They typically have generalised bills, similar to those of a thrush or warbler, except for the scimitar babblers which, as their name implies, have strongly decurved bills. Most have predominantly brown plumage, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Kitulgala
Kitulgala is a small town in the west of Sri Lanka. The Academy Award-winning ''The Bridge on the River Kwai'' was filmed on the Kelani River near Kitulgala, although nothing remains now except the concrete foundations for the bridge. Kitulgala is also a base for white-water rafting, which starts a few kilometres upstream and also popular as a location for adventure based training programs. Features The Kelani river is wide at Kitulgala, but it is shallow apart from a deep channel near the opposite bank, so in the drier months it provides a safe and attractive place to swim, wash and play. The river can be crossed by walking out across the shallows and crossing the deep channel in a dugout canoe, which is stabilised with an outrigger. Sri Lanka's most recently discovered bird, the Serendib scops owl was originally heard calling by Deepal Warakagoda in these forests. The hills above the rubber plantations also have mountain hawk eagle, crested treeswift and Layard's parakeet. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laughingthrush
The laughingthrushes are a family, Leiothrichidae, of Old World passerine birds. They are diverse in size and coloration. These are birds of tropical areas, with the greatest variety in Southeast Asia and the Indian subcontinent. The entire family used to be included in the Old World babbler family Timaliidae. Characteristics They are small to medium-sized birds. They have strong legs, and many are quite terrestrial. They typically have generalised bills, similar to those of a thrush. Most have predominantly brown plumage, with minimal difference between the sexes, but many more brightly coloured species also exist. This group is not strongly migratory, and most species have short rounded wings, and a weak flight. They live in lightly wooded or scrubland environments, ranging from swamp to near-desert. They are primarily insectivorous, although many will also take berries, and the larger species will even eat small lizards and other vertebrates. Taxonomy The family Leioth ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...
