Merops Philippinus
The blue-tailed bee-eater (''Merops philippinus'') is a near passerine bird in the bee-eater family Meropidae. It is widely distributed across South and Southeast Asia where many populations are strongly migratory, and seen seasonally in many parts but breeding colonially in small areas across their range, mostly in river valleys, where they nest by tunneling into loamy sand banks. They are seen mostly in open habitats close to water. Description This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green; its face has a narrow blue patch with a black eye stripe, and a yellow and brown throat; the tail is blue and the beak is black. The three outer toes are united around their bases. It can reach a length of 23–26 cm, including the two elongated central tail feathers which can be just two inches more than the remaining ten feathers. Sexes are alike. This species is usually found near water and like other bee-eaters it predominantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yala National Park
Yala (යාල) National Park is the most visited and second largest national park in Sri Lanka, bordering the Indian Ocean. The park consists of five blocks, two of which are now open to the public, and also adjoining parks. The blocks have individual names such as, Ruhuna National Park (Block 1), and Kumana National Park or 'Yala East' for the adjoining area. It is situated in the southeast region of the country, and lies in Southern Province and Uva Province. The park covers and is located about from Colombo. Yala was designated as a wildlife sanctuary in 1900, and, along with Wilpattu was one of the first two national parks in Sri Lanka, having been designated in 1938. The park is best known for its variety of wild animals. It is important for the conservation of Sri Lankan elephants, Sri Lankan leopards and aquatic birds. There are six national parks and three wildlife sanctuaries in the vicinity of Yala. Among the largest is Lunugamvehera National Park. The park is situ ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of South China
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. Birds ...

Meropidae
The bee-eaters are a group of non-passerine birds in the family Meropidae, containing three genera and thirty species. Most species are found in Africa and Asia, with a few in southern Europe, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All have long down-turned bills and medium to long wings, which may be pointed or round. Male and female plumages are usually similar. As their name suggests, bee-eaters predominantly eat flying insects, especially bees and wasps, which are caught on the wing from an open perch. The insect's stinger is removed by repeatedly hitting and rubbing the insect on a hard surface. During this process, pressure is applied to the insect's body, thereby discharging most of the venom. Most bee-eaters are gregarious. They form colonies, nesting in burrows tunnelled into vertical sandy banks, often at the side of a river or in flat ground. As they mostly live in col ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Powai Lake
Powai Lake (Pronunciation: əʋəiː is an artificial lake, situated in Mumbai, in the Powai valley, where a Powai village with a cluster of huts existed. The city suburb called Powai shares its name with the lake. Indian Institute of Technology Bombay, one of the premier institutions of science and technology in India, is located to the east of the lake. Another famous institution, the National Institute of Industrial Engineering (NITIE), is also located close to the lake. Housing complexes and plush hotels are developed all around the lake periphery. Population around the lake has thus substantially increased over the years. When it was built, the lake had an area of about and the depth varied from about (at the periphery) to at its deepest. The Powai Lake has gone through many stages of water quality degradation. The lake water which used to supply drinking water for Mumbai has been declared unfit to drink. The lake remains a tourist attraction. History Before the lake ...
