Dryoscopus
''Dryoscopus'' is a genus of bird in the Malaconotidae or bushshrike family. Its members are known as puffbacks. The six species, all of fairly uniform appearance and habits, are native to various parts of sub-Saharan Africa. The name ''Dryoscopus'' is a compound Greek word: ''drus'' from the Greek word for "tree" and ''skopos'', meaning "watcher or lookout". Structure and habits Puffbacks are small, active bushshrikes that show a superficial resemblance to boubous. They however display only rudimentary duetting, have red or reddish irides, are smaller and compact with bouncy flight, and display sexual dimorphism. Characteristically, the long, loose and pale feathers of the male bird's back and rump are puffed out conspicuously during display. At the same time he may fly about, calling loudly. Comparable habits are found in some related genera (cf. '' Bocagia'', ''Bias'', '' Lanioturdus'', ''Batis'' and '' Dyaphorophyia''). They move about in pairs in the upper strata of tree ...

Black-backed Puffback
The black-backed puffback (''Dryoscopus cubla'') is a species of passerine bird in the family Malaconotidae. They are common to fairly common sedentary bushshrikes in various wooded habitats in Africa south of the equator. They restlessly move about singly, in pairs or family groups, and generally frequent tree canopies. Like others of its genus, the males puff out the loose rump and lower back feathers in display, to assume a remarkable ball-like appearance. They draw attention to themselves by their varied repertoire of whistling, clicking and rasping sounds. Their specific name ''cubla'', originated with Francois Levaillant, who derived it from a native southern African name, where the "c" is an onomatopoeic click sound. None of the other five puffback species occur in southern Africa. Description They measure about 17 cm in length, and the sexes are similar though easily distinguishable. Adult males have the upperparts deep blue-black with a slight luster. The black c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Puffback
The northern puffback (''Dryoscopus gambensis'') is a species of bird in the family Malaconotidae. It is found in northern sub-Saharan Africa. It forms a superspecies with the black-backed puffback, which replaces it in eastern equatorial and southern Africa. Habitat Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and moist savanna. Races There are five accepted races: * ''D. g. gambensis'' (M. H. C. Lichtenstein, 1823) – Senegambia to coastal Gabon * ''D. g. congicus'' Sharpe, 1901 – lower catchment of Congo River * ''D. g. malzacii'' (Heuglin, 1870) – eastern Cameroon to northwestern Tanzania * ''D. g. erythreae'' Neumann, 1899 – Eritrea to South Sudan * ''D. g. erwini'' Sassi, 1923 – Itombwe in eastern DRC Gallery File:Dryoscopus gambensis (Malaconotidae) (Northern Puffback) - (male), Mole National Park, Ghana, crop.jpg, Male ''D. g. gambensis'' at Mole National Park, Ghana File:Northern Puffback ...

Pink-footed Puffback
The pink-footed puffback (''Dryoscopus angolensis'') is a species of bird in the family Malaconotidae. It is found in western Central Africa as well as in the Albertine Rift montane forests and northern adjacent areas of Kenya, Uganda and the eastern Congo Basin. Its natural habitat is subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucia ...s.

Pringle's Puffback
Pringle's puffback (''Dryoscopus pringlii'') is a species of bird in the family Malaconotidae. It is found in southern Ethiopia, Kenya, Somalia, and northern Tanzania. Its natural habitat is dry 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 ....

Sabine's Puffback
Sabine's puffback ( ; ''Dryoscopus sabini''), also known as the large-billed puffback, is a species of bird in the family Malaconotidae. It is native to the African tropical rainforest (western and sparsely throughout Central Africa). Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps. Its common name and Latin binomial commemorate lawyer and naturalist Joseph Sabine Joseph Sabine FRS ( ; 6 June 1770 – 24 January 1837) was an English lawyer, naturalist and writer on horticulture.

Indigenous (ecology)
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific nam ...
