Green-tailed Bristlebill
The green-tailed bristlebill (''Bleda eximius'') is a species of songbird in the bulbul family, Pycnonotidae. It is found in West Africa from Sierra Leone to Ghana. Its natural habitat is tropical moist lowland forests. It is threatened by habitat loss. The green-tailed bristlebill was originally described in the genus ''Trichophorus ''Criniger'' is a genus of songbirds in the bulbul family, Pycnonotidae. The species of ''Criniger'' are found in western and central Africa. Taxonomy The genus ''Criniger'' was introduced in 1820 by the Dutch zoologist Coenraad Jacob Temminck, ...'' (a synonym for ''Criniger''). Formerly, some authorities considered the yellow-lored bristlebill as conspecific with the green-tailed bristlebill.

Gustav Hartlaub
Karel Johan Gustav Hartlaub (8 November 1814 – 29 November 1900) was a German physician and ornithologist. Hartlaub was born in Bremen, and studied at Bonn and Berlin before graduating in medicine at Göttingen. In 1840, he began to study and collect exotic birds, which he donated to the Bremen Natural History Museum. He described some of these species for the first time. In 1852, he set up a new journal with Jean Cabanis, the ''Journal für Ornithologie''. He wrote with Otto Finsch, ''Beitrag zur Fauna Centralpolynesiens: Ornithologie der Viti-, Samoa und Tonga- Inseln''. Halle, H. Schmidt. This 1867 work which has handcoloured lithographs was based on bird specimens collected by Eduard Heinrich Graeffe for Museum Godeffroy. A number of birds were named for him, including Hartlaub's Bustard, Hartlaub's Turaco, Hartlaub's Duck, and Hartlaub's Gull Hartlaub's gull (''Chroicocephalus hartlaubii''), also known as the king gull, it is a small gull.

Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Songbirds form one of the two major lineages of extant perching birds (~4000 species), the other being the Tyranni (~1000 species), which are most diverse in the Neotropics and absent from many parts of the world. The Tyranni have a simpler syrinx musculature, and while their vocalizations are often just as complex and striking as thos ...

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
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] |
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 ...

Habitat Loss
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 ...

Trichophorus
''Criniger'' is a genus of songbirds in the bulbul family, Pycnonotidae. The species of ''Criniger'' are found in western and central Africa. Taxonomy The genus ''Criniger'' was introduced in 1820 by the Dutch zoologist Coenraad Jacob Temminck, the name ''Criniger'' is Latin for "long-haired" (from ''crinis'', meaning "hair" and ''gerere'', meaning "to carry"). A year later Temminck designated the type species as the western bearded greenbul. Species The genus contains five species: * Western bearded greenbul (''Criniger barbatus'') *Eastern bearded greenbul (''Criniger chloronotus'') * Red-tailed greenbul (''Criniger calurus'') * White-bearded greenbul (''Criniger ndussumensis'') * Yellow-bearded greenbul (''Criniger olivaceus'') Former species Formerly, some authorities also considered the following species (or subspecies) as species within the genus ''Criniger'': * Striated bulbul (as ''Tricophorus striatus'' or ''Criniger striatus'') * Streak-eared bulbul (as ''Criniger ...

Bleda (bird)
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 exi ...
