Red-tailed Leaflove
The red-tailed leaflove (''Phyllastrephus scandens'') is a species of leaflove in the bulbul family, Pycnonotidae. It is found in western and central Africa. Taxonomy and systematics Although originally described in the genus ''Phyllastrephus'', the red-tailed leaflove was briefly transferred to the former genus ''Pyrrhurus'' (now subsumed into ''Phyllastrephus'') during the period 2009-2010 by the IOC. Some other authorities continue to classify the red-tailed leaflove in the genus ''Pyrrhurus''. Alternate names for the red-tailed leaflove include the African leaflove, common leaflove, leaflove and plain leaflove. Subspecies Two subspecies are recognized: * Uele leaflove (''P. s. scandens'') - Swainson, 1837: Found from Gambia and Senegal to northern Cameroon * Gabon leaflove (''P. s. orientalis'') - ( Hartlaub, 1883): Originally described as a separate species in the genus ''Xenocichla'' (a synonym for ''Bleda''). Found from northern Cameroon to southern Sudan, central Uganda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1837
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 ...

Phyllastrephus
''Phyllastrephus'' is a songbird genus in the bulbul family Pycnonotidae. Most of the species in the genus are typical greenbuls, though two are brownbuls, and one is a leaflove. Taxonomy and systematics The genus ''Phyllastrephus'' was introduced by the English naturalist William John Swainson in 1832 with ''Le Jaboteur'' ( Levaillant), now the terrestrial brownbul, as the type species. The genus name combines the Ancient Greek ''phullon '' meaning "leaf" with ''strephō'' meaning "to toss" or "to turn". Species The genus contains the following 20 species: * Lowland tiny greenbul (''Phyllastrephus debilis'') * Montane tiny greenbul (''Phyllastrephus albigula'') * White-throated greenbul (''Phyllastrephus albigularis'') * Xavier's greenbul (''Phyllastrephus xavieri'') * Icterine greenbul (''Phyllastrephus icterinus'') * Terrestrial brownbul (''Phyllastrephus terrestris'') * Cameroon olive greenbul (''Phyllastrephus poensis'') * Northern brownbul (''Phyllastrephus strepi ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

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 ...

Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification, Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification, Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the c ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenocichla
The bristlebills are a genus ''Bleda'' of passerine birds in the bulbul family Pycnonotidae. They are found in the forest understorey of western and central Africa. They forage for insects at or near ground-level, often near water. They will follow driver ant swarms to catch prey items fleeing from the ants and they frequently join mixed-species feeding flocks. They are 18–23 cm long with fairly long, stout bills. The upperparts are mainly green-brown while the underparts are yellow. The birds have whistling songs. The nest is made of leaves or sticks and built in a shrub or small tree. Two eggs are laid. Taxonomy The genus ''Bleda'' was introduced in 1857 by the French naturalist Charles Lucien Bonaparte with the red-tailed bristlebill as the type species. The genus was named after Bleda, elder brother of Attila and joint ruler of the Huns. Species The genus contains five species: * Red-tailed bristlebill (''Bleda syndactylus'') * Green-tailed bristlebill (''Bleda e ...
