Styan's Bulbul
Styan's bulbul (''Pycnonotus taivanus'', ) is an endemic species of bulbul found in eastern and southern Taiwan. Though common in some areas, it has been listed as a species vulnerable to extinction. Its decline has been caused by habitat destruction Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... and hybridisation with the closely related Chinese or light-vented bulbul. The two species' ranges overlap in several areas, partly because birds of the latter species have been released for Buddhist ceremonies. The species has already become extinct in Yilan County (Taiwan). Taxonomy and systematics Alternate names for Styan's bulbul include the Formosan black-headed bulbul and Taiwan black-headed bulbul ( zh, 烏頭翁: meaning “black head bird”). The latter name is also used ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The IUCN Red List Of Threatened Species
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 sc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

IUCN
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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Frederick William Styan
Frederick William Styan (1858 – 15 September 1934) was an English tea merchant who spent many years in China. During his stay he obtained numerous specimens of fauna which were donated to the British Museum (Natural History). Several species such as Styan's bulbul are named after him. Styan was born in London to Thomas Styan (1819-1899) and Frances Sarah Lake (1823-1924). He worked as a clerk for Robert Anderson and Co. tea traders in Shanghai and Foochow from 1895 to 1903. His father was also a naturalist and collector of bird specimens which were bequeathed to his son. Along with J.D. La Touche and Charles Boughey Rickett they went on several expeditions to collect natural history specimens in China. Some were deposited in the museum in Shanghai while others were sent to the natural history museum in London. Styan maintained a personal collection of bird skins which he once displayed at the North China Insurance Company on Hankow Road in Shanghai. He also served as an honorary ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bulbul
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas. Taxonomy The family Pycnonotidae was introduced by the English zoologist George Robert Gray in 1840 as a subfamily Pycnonotinae of the thrush family Turdidae. The Arabic word ''bulbul'' (بلبل) is sometimes used to refer to the "nightingale" as well as the bulbul, but the English word ''bulbul'' refers to the birds discussed in this article.

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...

Yilan County, Taiwan
Yilan County, alternately spelled I-lan, is a County (Taiwan), county in northeastern Taiwan, Republic of China. Name The name ''Yilan'' derives from the Taiwanese indigenous peoples, indigenous Kavalan people. Other former names in reference to this area in the Yilan Plain include ''Kabalan'', ''Kavalan'', ''Kavaland'', ''kap-a-lan'', ''Yiland'' and ''Gilan''. Before 2009, the county's official name was transliterated as Ilan. History Early history Since early ages, many people have traveled from far places to Yilan. Taiwanese aborigines, Indigenous tribes that have settled in Yilan are Kavalan people and Atayal people. The Kavalan people came by the sea and lived by the river at Yilan Plain since around 1,000 years ago. They mostly speak the Austronesian languages. Their settlements consisted of small villages along rivers with around 40-50 communities scattered around the area with a total population of approximately 10,000 people. The Atayal people came by crossing ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

A Bird In East Taiwan
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Pycnonotus
''Pycnonotus'' is a genus of frugivorous passerine birds in the bulbul family Pycnonotidae. Taxonomy and systematics The genus ''Pycnonotus'' was introduced by the German zoologist Friedrich Boie in 1826 with the Cape bulbul as the type species. The name of the genus combines the Ancient Greek words ''puknos'' "thick" or "compact" and ''-nōtos'' "-backed". The genus contains the following 32 species: * Cream-vented bulbul (''Pycnonotus simplex'') * Olive-winged bulbul (''Pycnonotus plumosus'') * Asian red-eyed bulbul (''Pycnonotus brunneus'') * Straw-headed bulbul (''Pycnonotus zeylanicus'') * Cream-eyed bulbul (''Pycnonotus pseudosimplex'') * Ashy-fronted bulbul (''Pycnonotus cinereifrons'') * White-browed bulbul (''Pycnonotus luteolus'') * Ayeyarwady bulbul (''Pycnonotus blanfordi'') * Streak-eared bulbul (''Pycnonotus conradi'') * Stripe-throated bulbul (''Pycnonotus finlaysoni'') * Flavescent bulbul (''Pycnonotus flavescens'') * Aceh bulbul (''Pycnonotus snouckaerti' ...

Endemic Birds Of Taiwan
The island of Taiwan, which is located in southeast Asia at the junction of the East China Sea and South China Seas, is home to 30 endemic bird species. Endemic Bird Areas Birdlife International defines Endemic Bird Areas (EBAs) as places where the breeding ranges of two or more range-restricted species—those with breeding ranges of less than —overlap. In order to qualify, the whole of the breeding range of at least two range-restricted species must fall entirely within the EBA. The entire island of Taiwan has been designated as an Endemic Bird Area. In addition, Orchid Island (Lán Yǔ), km off the south-east coast of Taiwan has been designated as a secondary area, as two restricted-range species ( Taiwan green pigeon and elegant scops owl) occur there.
