Pycnonotus Cafer
The red-vented bulbul (''Pycnonotus cafer'') is a member of the bulbul family of passerines. It is a resident breeder across the Indian subcontinent, including Sri Lanka extending east to Burma and parts of Bhutan and Nepal. It has been introduced in many other parts of the world and has established itself in New Zealand, Argentina, Tonga and Fiji, as well as parts of Samoa, Australia, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species. Taxonomy and systematics In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-vented bulbul in his ''Ornithologie'' based on a specimen that he mistakenly believed had been collected from the Cape of Good Hope in South Africa. He used the French name ''Le merle hupé du Cap de Bonne Espérance'' and the Latin ''Merula Cristata Capitis Bonae Spei''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a spec ... [...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 ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Lantana Camara
''Lantana camara'' (common lantana) is a species of flowering plant within the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and more than in altitude. It has spread from its native range to around 50 countries, where it has become an invasive species. It first spread out of the Americas when it was brought to Europe by Dutch explorers and cultivated widely, soon spreading further into Asia and Oceania where it has established itself as a notorious weed, and in Goa it was introduced by the Portuguese. ''L. camara'' can outcompete native speci leading to a reduction in biodiversity. It can also cause problems if it invades agricultural areas as a result of its toxicity to livestock, as well as its ability to form dense thickets which, if left unchecked, can greatly reduce the Agricultural productivi ...

Leucism
Leucism () is a wide variety of conditions that result in the partial loss of pigmentation in an animal—causing white, pale, or patchy coloration of the skin, hair, feathers, scales, or cuticles, but not the eyes. It is occasionally spelled ''leukism''. Some genetic conditions that result in a "leucistic" appearance include piebaldism, Waardenburg syndrome, vitiligo, Chédiak–Higashi syndrome, flavism, isabellinism, xanthochromism, axanthism, amelanism, and Melanophilin mutations. Pale patches of skin, feathers, or fur (often referred to as "depigmentation") can also result from injury. Details ''Leucism'' is often used to describe the phenotype that results from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair, or feathers during development. This results in either the entire surface (if all pigment cells fail to develop) or patches of body surface (if only a subset are defective) having a lack of cells that can make pigment. ...

Pycnonotus Aurigaster
The sooty-headed bulbul (''Pycnonotus aurigaster'') is a species of songbird in the Bulbul family, Pycnonotidae. It is found in south-eastern Asia. Its natural habitat is subtropical or tropical moist lowland forests. Description A medium-sized songbird measuring between 18 and 21 centimetres in length with a short crest, the sooty-headed bulbul can be distinguished from the similar red-vented bulbul by its tan front, less extensive area of black on its head and gold-colored vent in certain subspecies. Its call is a series of whistled notes similar in tone to that of the red-whiskered bulbul, but delivered in a more hurried manner. Taxonomy and systematics The sooty-headed bulbul was originally described in the genus '' Turdus''. Alternate names for the sooty-headed bulbul include the golden-vented bulbul and several names used for other species (black-capped, red-vented, white-eared and yellow-vented bulbul). Subspecies Nine subspecies are recognized: * ''P. a. chrysorrhoid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pycnonotus Leucogenys
The Himalayan bulbul (''Pycnonotus leucogenys''), or white-cheeked bulbul, is a species of songbird in the bulbul family found in Central and South Asia.

Salt Range
The Salt Range ( pnb, ) is a mountain range in the north of Punjab province of Pakistan, deriving its name from its extensive deposits of rock salt. The range extends along the south of the Potohar Plateau and the north of the Jhelum River. The Salt Range contains the great mines of Khewra, Kalabagh and Warcha which yield vast supplies of salt. Coal of a medium quality is also found. In the Himalayan and Salt Range, rock containing fossil of marine life go back to the Ediacaran period (up to 570 million years ago), which shows these rocks have developed out of sea sediments, and that where we have the Himalayas now was once a sea. *Sakaser is the highest peak of Salt Range. *Namal Lake, Khabikki Lake and Uchhali Lake are lakes in the Salt Range. History An inscription found at Kura in the Salt Range records the building of a Buddhist monastery by a person named Rotta Siddhavriddhi during the reign of the Huna ruler Toramana.

Edward Blyth
Edward Blyth (23 December 1810 – 27 December 1873) was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. Blyth was born in London in 1810. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. 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 A.O. Hume, Samuel Tickell, Robert Swinhoe and others. He remained as curator until 1862, when ill-health forced his return to England. His ''Natural History of the Cranes'' was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbl ...
