Deepal Warakagoda
Deepal Warakagoda (born 1965) is a prominent Sri Lankan ornithologist. His early working career was in electronics, but for many years he has studied birds and also works as a professional guide for birding tours of the island. He is mostly known for his records as the ornithologist who has seen the greatest amount of species in Sri Lanka. Deepal Warakagoda is also one of the major roles of the Ceylon birds club. He works hard to conserve natural sights and fauna in Sri Lanka and has his own career experience for over 25 years. Discoveries He discovered a new species of bird endemic to Sri Lanka, the Serendib Scops owl. His expertise in vocalizations had enabled him to realize that an owl he heard calling near Kitulgala rain forest was an unknown species, and he later saw this bird in January 2001 in the Sinharaja rain forest with assistance of a few. He surrounded the bird's habitat and took photographs while it was roosting under a thick bush. This new-found species of scops ...

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 List of cities in Sri Lanka, 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 people, 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.

Serendib Scops Owl
The Serendib scops owl (''Otus thilohoffmanni'') is the most recently discovered bird of Sri Lanka. It was originally located by its unfamiliar ''poo-ooo'' call in the Kitulgala rainforest by prominent Sri Lankan ornithologist Deepal Warakagoda. Six years later, it was finally seen by him on 23 January 2001 in Sinharaja, and formally described as a species new to science in 2004. Apart from Sinharaja and Kitulgala, it has also been found at Runakanda Reserve in Morapitiya and Eratna Gilimale. It is known as පඩුවන් බස්සා in Sinhala. It is the first new bird to be discovered in Sri Lanka since 1868, when the Sri Lanka whistling thrush—then Ceylon whistling thrush—(''Myophonus blighi'') was discovered. It is also the 24th (according to some authorities the 27th) endemic bird species for Sri Lanka. The habitat of the Serendib scops owl is in the southern rainforests of Sri Lanka. There is an altitudinal range from 30 to 50 metres. This owl has no c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithology
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ... [...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 ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of South Asia
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drongo
The drongos are a family, Dicruridae, of passerine birds of the Old World tropics. The 30 species in the family are placed in a single genus, ''Dicrurus''. Drongos are mostly black or dark grey, short-legged birds, with an upright stance when perched. They have forked tails and some have elaborate tail decorations. They feed on insects and small birds, which they catch in flight or on the ground. Some species are accomplished mimics and have a variety of alarm calls, to which other birds and animals often respond. They are known to utter hoax alarm calls that scare other animals off food, which the drongo then claims. Taxonomy The genus ''Dicrurus'' was introduced by French ornithologist Louis Pierre Vieillot for the drongos in 1816. The type species was subsequently designated as the balicassiao (''Dicrurus balicassius'') by English zoologist George Robert Gray in 1841. The name of the genus combines the Ancient Greek words ''dikros'' "forked" and ''oura'' "tail". "Dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
