Buff-vented Bulbul
The buff-vented bulbul (''Iole crypta'') is a species of songbird in the bulbul family, Pycnonotidae. It is found in south-eastern Myanmar, south-western Thailand, on the Malay Peninsula, Sumatra and nearby islands. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss. Taxonomy and systematics The former scientific name, ''Iole olivacea'' Blyth, 1844, has now been ruled as permanently invalid by the IOC. Some authorities have classified the buff-vented bulbul in the genera ''Hypsipetes'' and ''Microscelis''. Formerly, Charlotte's bulbul was considered as conspecific with the buff-vented bulbul until split by the IOC The International Olympic Committee (IOC; , CIO) is the international, non-governmental, sports governing body of the modern Olympic Games. Founded in 1894 by Pierre de Coubertin and Demetrios Vikelas, it is based in L ... in 2017. Alternate names for the buff-vented bulbul include the cr ...

Nopphitam District
Nopphitam (, ) is a district (''amphoe'') of Nakhon Si Thammarat province, southern Thailand. History The district was founded on 1 April 1995 by splitting off the four western ''tambons'' from Tha Sala district. On 15 May 2007, all 81 minor districts were upgraded to full districts. On 24 August, the upgrade became official. Geography Neighboring districts are (from the northeast clockwise): Sichon, Tha Sala, Phrom Khiri and Phipun of Nakhon Si Thammarat Province and Ban Na San and Kanchanadit of Surat Thani province. Nopphitam contains the northernmost part of the Khao Luang National Park, protecting a large part of the Nakhon Si Thammarat mountain range. Administration The district is divided into four sub-districts (''tambons''), which are further subdivided into 38 villages (''mubans''). There are no municipal (''thesaban'') areas, and four tambon administrative organization ''Tambon'' (, ) is a local governmental unit in Thailand. Below district (''amphoe'') an ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Harry C
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1918
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 ...

Iole (genus)
''Iole'' is a genus of songbirds in the bulbul family (biology), family, Pycnonotidae. They are native to tropical eastern Asia, from India to China and south through Southeast Asia to northern Indonesia. Taxonomy and systematics While some older sources merge this genus into ''Hypsipetes'', this is neither advisable nor technically correct. The two genera stand well apart, and to phylogenetically justify their merging, the entire "''Hypsipetes'' group" of bulbuls would need to be united in a single genus. That would include ''Hemixos'', ''Ixos'', ''Microscelis'' and ''Tricholestes'', and probably also ''Alophoixus'' and the monotypic ''Setornis''. The hook-billed bulbul may in fact be the closest living relative to the species in ''Iole'', but altogether the present genus may well be a quite basal (evolution), basal lineage of the traditional "''Hypsipetes'' group" of bulbuls, with no particularly close relatives among any of these other genera.Gregory (2000), Pasquet ''et al.'' ...

Microscelis
''Microscelis'' is a former genus of bulbuls described by George Robert Gray in 1840. The following species were classified within the genus ''Microscelis'' but are now assigned to ''Iole'', ''Hemixos'' or '' Hypsipetes'': * Olive bulbul (as ''Microscelis viridescens'') * Buff-vented bulbul (as ''Microscelis charlottae'') * Ashy bulbul (as ''Microscelis flavala'') * Brown-eared bulbul The brown-eared bulbul (''Hypsipetes amaurotis'') is a medium-sized bulbul native to eastern Asia. It is extremely common within the northern parts of its range and can be found from southern Sakhalin to the northern Philippines. Taxonomy and ...

Hypsipetes
__NOTOC__ ''Hypsipetes'' is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland. Most ''Hypsipetes'' bulbuls are dark greyish birds with orange or red bills and feet. The feathers on top of the head are slightly elongated and usually black, and can be erected to form a short and wispy crest. Taxonomy and systematics The genus ''Hypsipetes'' was introduced in 1831 by the Irish zoologist Nicholas Aylward Vigors with ''Hypsipetes psaroides'' as the type species. This taxon is now a subspecies of the black bulbul ''Hypsipetes leucocephalus psaroides''. The genus name combines the Ancient Greek ''hupsi'' meaning "high" with ''petēs'' meaning "-flyer". Species The genus contains 26 species: * Nicobar bulbul, ''Hypsipetes nicobariensis'' (formerly placed in ''Ixos'') * Philip ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...
