Bwindi Impenetrable Forest
The Bwindi Impenetrable Forest is a large primeval forest located in south-western Uganda in the Kanungu District. The Bwindi forest is on the edge of the Albertine Rift, the western branch of the East African Rift, at elevations ranging from . The forest contains around 160 species of trees and over 100 species of ferns. Origin of name The name Bwindi is derived from the Runyakitara word ''Mubwindi'' and means "a place full of darkness". This name comes from the extensive stands of bamboo interspersed amongst the larger forest hardwoods. The bamboo and thick ground cover of ferns, vines, and other plant growth severely hinder direct access on foot. Also known as the "Place of Darkness", the forest is on the edge of the western arm of the Great Rift Valley, only a few kilometers from the Democratic Republic of the Congo (DRC) border and about north of the Virunga Mountains. Wildlife The forest is one of the most biologically diverse areas on Earth. Half of the world's p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Birds Of Sub-Saharan 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 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 swim ...

Cinnyris
''Cinnyris'' is a genus of sunbirds. Its members are sometimes included in ''Nectarinia''. They are generally known as double-collared sunbirds because the fringe of their bib usually includes a band of contrastingly coloured feathers. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed. Taxonomy The genus was introduced by the French naturalist Georges Cuvier in 1816. The type species was designated as "''Certhia splendida'' Shaw" by George Robert Gray in 1855. This taxon is a junior synonym of ''Certhia coccinigaster'' described by John Latham in 1801. This is now the splendid sunbird. The name ''Cinnyris'' is from the Ancient Greek κιννυρις (''kinnyris''), an unknown small bird mentioned by Hesychius of Alexandria Hesyc ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalu ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Olive-bellied Sunbird
The olive-bellied sunbird (''Cinnyris chloropygius'') is a species of bird in the family Nectariniidae. It is widely spread across African tropical rainforest. Description The olive-bellied sunbird is a small species, and very similar to the tiny sunbird (''Cinnyris minullus'') in appearance. The adult male has a metallic green head, back and throat, dark brown wings, a metallic blue rump and a black tail with a purplish-blue sheen. It has a narrow blue breast band above a wider scarlet breast patch, lemon-yellow and an olive belly. It differs from the slightly smaller tiny sunbird in having a larger beak and no blue bars among the red breast plumage. The adult female has an olive-brown head and upper parts, dark brown wings and dark brown tail. The underparts are olive washed with yellow, and are yellower and less streaked than the tiny sunbird. Ecology The olive-bellied sunbird moves about singly or in pairs, or sometimes in groups of about six birds. It forages in the lowe ...

Oriole Finch
The oriole finch (''Linurgus olivaceus'') is a small passerine bird in the finch family. It is found in Africa and is native to Burundi, Cameroon, Democratic Republic of the Congo, Equatorial Guinea, Kenya, Malawi, Nigeria, Rwanda, South Sudan, Tanzania and Uganda. It lives in subtropical or tropical moist evergreen montane forests. The male has a black head, a yellow body, black flight feathers and a stout bright yellow-orange conical bill. The female is a dull greenish-olive but has black flight feathers and a yellow bill. The oriole finch was formally described in 1843 by the British zoologist Louis Fraser under the binomial name ''Coccothraustes olivaceus''. It is now the only species placed in the genus ''Linurgus'' that was introduced by Ludwig Reichenbach in 1850. The exact relationship of this species to other finches is unclear. In their phylogenetic analysis published in 2012, Zuccon and colleagues found that the oriole finch was sister to the genus ''Serinus''. Th ...

Zosterops
''Zosterops'' (meaning "eye-girdle") is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical, Indomalayan, and Australasian realms. Typical white-eyes have a length of between . Their most characteristic feature is a conspicuous white feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The ''Zosterops'' 'griseotinctus''group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which maybe as close as apart. Systematics The genus ''Zosterops'' was introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The name combines the Ancient Greek words ''zōstēros'' "belt" or "girdle" and ''ōpos'' "eye". The type species was designated as the Malagasy white-e ...
