Southern Hill Myna
The southern hill myna (''Gracula indica'') is a member of the starling family. It is a resident of the forested regions of south India and Sri Lanka. This species moves around in flocks in the forest, and members of a flock keep in contact with a wide range of vocalizations. Etymology The French word for the bird ''mainate'' is probably derived from the Indo-Portuguese mainato, from the name of a songbird living near water, and is probably a metaphor since it refers to a man whose job is to wash the clothes of others. Description The southern hill myna has a shiny black plumage. It generally measures about twenty centimeters. It can live between 15 and 30 years. The legs are yellow, the beak is bright orange at the base and yellow at the tip. It has white spots on the primary remiges. Like other species of hill myna, the southern hill myna has yellow wattles on the head. Habitats and behavior The southern hill myna is present in southwestern India and Sri Lanka. It inhab ...

Biligiriranga Hills
The Biligirirangana Hills or Biligirirangan Hills (as referred to in biology and geology) is a hill range situated in south-western Karnataka, at its border with Tamil Nadu (Erode District) in South India. The area is called Biligiri Ranganatha Swamy Temple Wildlife Sanctuary or simply BRT Wildlife Sanctuary. It is a Protected area, protected reserve under the Wildlife Protection Act of 1972. Being close to the Eastern Ghats as well as the Western Ghats, the sanctuary has floral and faunal associations with both regions. The site was declared a tiger reserve in January 2011 by the Karnataka government, a few months after approval from India's National Tiger Conservation Authority. Location The hills are located at the north-west of the Western Ghats and the westernmost edge of the Eastern Ghats. Thus this area supports a diverse flora and fauna in view of the various habitat types present. A wildlife sanctuary of was created around the temple on 27 June 1974, and enlarged to o ...

Omnivore
An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivor ...

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 524 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. 34 species are confirmed as endemic (ecology), endemic. 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 north east monsoon from October to January). The wet zone, with two monsoons, is in the south western quarter of the island, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gracula
''Gracula'' is a genus of mynas, tropical members of the starling family of birds found in southern Asia and introduced to Florida in the United States. Taxonomy The genus ''Gracula'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is from Latin ''graculus'', an unknown bird sometimes identified as the western jackdaw. Of the seven species listed by Linnaeus, George Gray designated the common hill myna (''Gracula religiosa'') as the type species. Until recently only two species were recognised, ''G. religiosa'' and ''G. ptilogenys''. Previously, all ''Gracula'' were considered to belong to a very variable species commonly called the hill myna. Three additional subspecies of ''G. religiosa'' are increasingly being considered as distinct species. Formerly, the Sri Lanka hill myna was considered to be a subspecies of the common hill myna, but today all major authorities recognise them as separate. Compa ...

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 Species
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 ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Hill Myna
The common hill myna (''Gracula religiosa''), sometimes spelled "mynah" and formerly simply known as the hill myna or myna bird, is the myna most commonly seen in aviculture, where it is often simply referred to by the latter two names. It is a member of the starling family (Sturnidae), resident in hill regions of South Asia and Southeast Asia. The Sri Lanka hill myna, a former subspecies of ''G. religiosa'', is now generally accepted as a separate species ''G. ptilogenys''. The Enggano hill myna (''G. enganensis'') and Nias hill myna (''G. robusta'') are also widely accepted as specifically distinct, and many authors favor treating the southern hill myna (''G. indica'') from the Nilgiris and elsewhere in the Western Ghats of India as a separate species. The common hill myna is a popular talking bird. Its specific name '' religiosa'' may allude to the practice of teaching mynas to repeat prayers. Description This is a stocky jet-black myna, with bright orange-yellow patches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captivity
Captivity, or being held captive, is a state wherein humans or other animals are confined to a particular space and prevented from leaving or moving freely. An example in humans is imprisonment. Prisoners of war are usually held in captivity by a government hostile to their own. Animals are held in captivity in zoos, and often as pets and as livestock. Definition and scope Captivity is the state of being captive, of being imprisoned or confined. The word derives from the late Middle English ''captivitas'', and the Latin ''captivus'' and ''capere'', meaning to seize or take, which is also the root of the English word, "capture". In humans, captivity may include arrest and detention as a function of law enforcement and a civilian correctional system, detention of combatants in a time of war, as well as human trafficking, slave taking, and other forms of involuntary confinement, forced relocation, and servitude. In non-human animals, captivity may include confinement for the purpos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parrot
Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 genera comprising the order Psittaciformes (), found mostly in tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk ( IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia. Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...
