Little Grey Greenbul
The little grey greenbul (''Eurillas gracilis'') is a species of the bulbul family of passerine birds. It is widely distributed across the African tropical rainforest. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps. Taxonomy and systematics The little grey greenbul was originally described in the genus '' Andropadus'' and was re-classified to the genus ''Eurillas'' in 2010. Alternatively, some authorities classify the little greenbul in the genus ''Pycnonotus''. Alternate names for the little grey greenbul include the grey greenbul and little grey bulbul. Subspecies Three subspecies are recognized. Some authorities have also considered Ansorge's greenbul as a subspecies of the little grey greenbul: * Gold Coast little grey greenbul (''E. g. extrema'') - (Hartert, 1922): Found from Sierra Leone to south-western Nigeria * ''E. g. gracilis'' - Cabanis Cabanis is the surname of: *George Cabanis (1815-1892), American pol ...

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. Cabanis was born in Berlin to an old Huguenot family who had moved from France. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, returning in 1841 with a large natural history collection. He was assistant and later director of the Natural History Museum of Berlin (which was at the time the Berlin University Museum), taking over from Martin Lichtenstein. He founded the ''Journal für Ornithologie'' in 1853, editing it for the next forty-one years, when he was succeeded by his son-in-law Anton Reichenow. He died in Friedrichshagen. A number of birds are named after him, including Cabanis's bunting ''Emberiza cabanisi'', Cabanis's spinetail ''Synallaxis cabanisi'', Azure-rumped tanager The azure-rumped tanager or Cabanis's tanager (''Poecilostreptus cabanisi'') is a species of bird in the family Thraupidae.

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' ...

Birds Of The African Tropical Rainforest
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 ...

Eurillas
''Eurillas'' is a genus of greenbuls, passerine birds in the bulbul family Pycnonotidae. Taxonomy The genus ''Eurillas'' was introduced in 1899 by the American ornithologist Harry C. Oberholser with the little greenbul as the type species. The genus name combines the Ancient Greek ''eurus'' meaning "broad" or "wide" and ''illas'' meaning "thrush". This genus was formerly synonymized with the genus '' Andropadus''. A molecular phylogenetic study of the bulbul family published in 2007 found that ''Andropadus'' was polyphyletic. In the revision to the generic classification five species were moved from ''Andropadus'' to the resurrected genus ''Eurillas''. Species The genus contains five species: * Little greenbul (''Eurillas virens'') * Yellow-whiskered greenbul (''Eurillas latirostris'') * Plain greenbul (''Eurillas curvirostris'') * Little grey greenbul (''Eurillas gracilis'') * Ansorge's greenbul Ansorge's greenbul (''Eurillas ansorgei'') or Ansorge's bulbul, is a species ...

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ansorge's Greenbul
Ansorge's greenbul (''Eurillas ansorgei'') or Ansorge's bulbul, is a species of the bulbul family of passerine birds. It is found in western and central Africa. Its natural habitat is subtropical or tropical moist lowland forests. Taxonomy and systematics Ansorge's greenbul was originally described in the genus '' Andropadus'' and was re-classified to the genus ''Eurillas'' in 2010. Alternatively, some authorities classify Ansorge's greenbul in the genus ''Pycnonotus''. Some authorities have considered Ansorge's greenbul as a subspecies of the little grey greenbul.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...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.

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Forest
A forest is an area of land dominated by 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 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 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
