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 5,000 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 (~4,000 species), the other being the Tyranni (~1,000 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 ... [...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 166 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 Persian 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.

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 Dorylus, 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 beak, bills. The upperparts are mainly green-brown while the underparts are yellow. The birds have whistling bird song, 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: Former species Formerly, some authorities also considered the ...

Honeyguide Greenbul
The honeyguide greenbul (''Baeopogon indicator'') is a species of songbird in the bulbul family, Pycnonotidae. It is widespread throughout the African tropical rainforest. Taxonomy and systematics The honeyguide greenbul was originally described in the genus ''Criniger'' and was later re-classified to the genus ''Baeopogon''. Alternate names for the honeyguide greenbul include the honeyguide bulbul and white-tailed greenbul. The latter name is also used as an alternate name by Sjöstedt's greenbul and the swamp palm bulbul. Subspecies Two subspecies of the honeyguide greenbul are recognized: * Upper Guinea honeyguide greenbul (''B. i. leucurus'') - ( Cassin, 1855): Originally described as a separate species in the genus ''Trichophorus'' (a synonym for ''Criniger ''Criniger'' is a genus of songbirds in the bulbul family, Pycnonotidae.

Swamp Palm Bulbul
The swamp palm bulbul (''Thescelocichla leucopleura''), is a species of songbird in the bulbul family, Pycnonotidae. It is monotypic within the genus ''Thescelocichla''. Taxonomy and systematics The swamp palm bulbul was originally described in the genus ''Phyllastrephus''. Alternative names for the swamp palm bulbul include the swamp bulbul, swamp greenbul, swamp palm greenbul, white-tailed greenbul and white-tailed palm greenbul. The alternate name 'white-tailed greenbul' is also used by the honeyguide greenbul and Sjöstedt's greenbul.

Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Baeopogon
''Baeopogon'' is a genus of passerine birds in the bulbul family, Pycnonotidae. Taxonomy The genus ''Baeopogon'' was introduced in 1860 by the German ornithologist Ferdinand Heine with the honeyguide greenbul as the type species. The name combines the Ancient Greek ''baios'' ( βαιός) meaning "small" or "little" with ''pōgōn'' meaning "beard". The genus contains two species: * Honeyguide greenbul (''Baeopogon indicator'') * Sjöstedt's greenbul Sjöstedt's greenbul (''Baeopogon clamans'') is a species of songbird in the bulbul family, Pycnonotidae.

Birds Of Central Africa
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 furth ...
