Birds Described In 1849
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parakeets
A parakeet is any one of many small- to medium-sized species of parrot, in multiple genera, that generally has long tail feathers. Etymology and naming The name ''parakeet'' is derived from the French word ''perroquet'', which is reflected in some older spellings that are still sometimes encountered, including paroquet or paraquet. However, in modern French, ''perruche'' is used to refer to parakeets and similar-sized parrots. In American English, the word ''parakeet'' usually refers to the budgerigar, which is one species of parakeet. Summary Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. The Australian budgerigar, also known as "budgie", ''Melopsittacus undulatus'', is probably the most common parakeet. It was first described by zoologists in 1891. It is the most popular species of parakeet kept as a pet in North America and Europe. The term "grass parakeet" (or ''grasskeet'') ref ...

Endemic Birds Of Sri Lanka
Sri Lanka is home to 34 Endemism, endemic bird species. The 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 over the years. This is largely due to "Taxonomy (biology), close taxonomic revisions". The number of endemic species has fluctuated from 20 to 47. Since 1977 the number has settled at around 21. The figure was increased to 23 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, within some Sri Lankan circles considere ...

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 ...

Psittacula
''Psittacula'', also known as Afro-Asian ring-necked parrots, is a genus of parrots from Africa and Southeast Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of parrot which has the majority of its species in continental Asia. Of all the extant species only ''Psittacula calthropae'', ''Psittacula caniceps'' and ''Psittacula echo'' do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, ''Psittacula krameri'', is one of the most widely distributed of all parrots. The other two Asian genera, ''Loriculus'' and ''Psittinus'' are represented by only two species each, which occur in the mainland part of Asia. The majority of the ''Loriculus'' species occur on islands. Moreover, since ''Loriculus'' is spread across both sides of the Wallace Line it can be considered more Australasian than Asian. These p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banknotes Of The Sri Lankan Rupee
The banknotes of the Sri Lanka rupee are part of the physical form of Sri Lanka's currency. The issuance of the rupee banknotes began in 1895.

These were followed by 10 rupee notes in 1894, 1000 rupee notes in 1899, 50 rupee notes in 1914, 1 and 2 rupee notes in 1917 and 100 and 500 rupee notes in 1926. In 1942, emergency issues for 5, 10, 25 and 50 cents were introduced and issued until 1949. In 1951, the Central Bank of Ceylon took over the issuance of paper money, introducing 1 and 10 rupee notes. These were followed in 1952 by 2, 5, 50 and 100 rupee notes.

He set about updating the museum's catalogues, publishing a ''Catalogue of the Birds of the Asiatic Society'' in 1849. He was prevented from doing much fieldwork himself, but received and described bird specimens from Allan Octavian Hume, A.O. Hume, Samuel Tickell, Robert Swinhoe among others.

Sri Lankan Rupee
The Sri Lankan rupee (, ; Currency symbol, symbol: ₨ in English, රු in Sinhala, ௹ in Tamil; ISO 4217, ISO code: LKR), known until 1972 as the Ceylon rupee, is the currency of Sri Lanka. It is subdivided into 100 cent (currency), cents (, ), but cents are rarely seen in circulation due to their low value. It is issued by the Central Bank of Sri Lanka. The abbreviation ''Re'' (singular) and ''Rs'' (plural) is generally used, the World Bank suggests SL Rs as a fully disambiguating abbreviation for distinction from other currencies named "rupee".

Sinhala Language
Sinhala ( ; Sinhala: , , ), sometimes called Sinhalese ( ), is an 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. It is also the first language of about 2 million other Sri Lankans, as of 2001. It is written in the Sinhalese script, a Brahmic script closely related to the Grantha script of South India. The language has two main varieties, written and spoken, and is a notable example of the linguistic phenomenon known as diglossia. 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 Buddhist literature. Early forms of the Sinhalese language are attested to as early as the 3rd century BCE. The language of these inscriptions, still retaining long vowels and aspirated consonants, is a Prakrit similar to Magadhi, a regional associate of the Middle-Indian Prakrits that had been ...
