Prigogine's Sunbird
Prigogine's sunbird or Prigogine's double-collared sunbird (''Cinnyris prigoginei'') is a species of bird in the family Nectariniidae. Taxonomy It is sometimes considered a subspecies of the greater double-collared sunbird (''Cinnyris afer''). Alternatively, it has been considered related to other members of the greater double-collared sunbird species complex, including Stuhlmann's sunbird (''Cinnyris stuhlmanni'') and montane double-collared sunbird (''Cinnyris ludovicensis''), but it is now regarded as a full species. Distribution and habitat It is endemic to the Marungu highlands of Tanganyika Province, southeastern Democratic Republic of the Congo. Its natural habitat is montane forest. Conservation It is threatened by 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 dea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James David Macdonald (ornithologist)
James David Macdonald FLS FZS FIB (3 October 1908 – 17 September 2002) was a Scottish-Australian ornithologist and ornithological writer. A traditional museum ornithologist, he did much to build up the collections of African and Australian birds held by the British Museum, as well as popularising ornithology through his writings. Education and career Macdonald was born in the village of Foyers, from Inverness in Scotland.Dow (2003). He attended Foyers Public School from 1913 to 1924 before obtaining a bursary to complete his secondary education at the Inverness Royal Academy, from which he graduated Dux in Art in 1927. He studied natural science at the University of Aberdeen, graduating with a BSc in Forestry in 1930 and in Pure Science (botany and zoology) in 1932, following which he carried out research on decapod crustaceans with the Scottish Fisheries Board and the Plymouth Marine Laboratory. In 1935 Macdonald was appointed to a position at the British Natural H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
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. B ...

Nectariniidae
Sunbirds and spiderhunters make up the family Nectariniidae of passerine birds. They are small, slender passerines from the Old World, usually with downward-curved bills. Many are brightly coloured, often with iridescent feathers, particularly in the males. Many species also have especially long tail feathers. Their range extends through most of Africa to the Middle East, South Asia, South-east Asia and southern China, to Indonesia, New Guinea and northern Australia. Species diversity is highest in equatorial regions. There are 145 species in 16 genera. Most sunbirds feed largely on nectar, but will also eat insects and spiders, especially when feeding their young. Flowers that prevent access to their nectar because of their shape (for example, very long and narrow flowers) are simply punctured at the base near the nectaries, from which the birds sip the nectar. Fruit is also part of the diet of some species. Their flight is fast and direct, thanks to their short wings. The sun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Double-collared Sunbird
The greater double-collared sunbird (''Cinnyris afer'') (formerly placed in the genus ''Nectarinia''), is a small bird in the sunbird family. Distribution and habitat The sunbird breeds in southern South Africa. It is mainly resident, but partly migratory in the northeast of its range. It is common in gardens, fynbos, forest edges and coastal scrub. Description This sunbird is 14 cm long and exhibits a clear sexual dimorphism. The adult male has a glossy, metallic green head, throat upper breast and back. It has a broad brilliant red band across the chest, separated from the green breast by a narrow metallic blue band. The rest of the underparts are pale grey. When displaying, yellow feather tufts can be seen on the shoulders. The plumage on the female is pale grey, darker in the wings. As with other sunbirds the bill is long and decurved. The bill, legs and feet are black. The eye is dark brown. The male can be distinguished from the similar lesser double-collared sunb ...

Stuhlmann's Sunbird
The Rwenzori double-collared sunbird (''Cinnyris stuhlmanni''), also called Stuhlmann's sunbird or the Rwanda double-collared sunbird, is a species of bird in the family Nectariniidae. It is found in the Ruwenzori range of mountains in south central Africa. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It is sometimes considered to be a subspecies of the greater double-collared sunbird (''Cinnyris afer''). Some authors consider this bird to be part of a species complex with ''Cinnyris afer'', where it joins Ludwig's double-collared sunbird (''Cinnyris ludovicensis'') and Prigogine's double-collared sunbird (''Cinnyris prigoginei''). As with other closely related species, each inhabiting different locations, there are subtle similarities and differences between the local populations, and their taxonomic Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Double-collared Sunbird
Ludwig's double-collared sunbird (''Cinnyris ludovicensis'') or the montane double-collared sunbird, is a small passerine bird which breeds in forested mountains above in western Angola as well as the Nyika Plateau of northern Malawi and northeastern Zambia. This bird is sometimes considered to be con-specific with the greater double-collared sunbird (''Cinnyris afer''). It is sometimes placed in the genus ''Nectarinia''. Description The sunbird is a medium-size species. The adult male has a glossy, metallic green head, throat upper breast and back with a golden sheen. The upper-tail coverts are metallic blue and the tail black glossed with blue. The throat and upper breast are metallic green, the lower breast scarlet and the rest of the underparts are dark olive. When displaying, yellow feather tufts are visible on the shoulders. As with other sunbirds the bill is long and decurved. The eye is dark brown while the beak, legs and feet are black. The adult female has dark greyish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marungu Highlands
The Marungu highlands are in the Tanganyika Province of the Democratic Republic of the Congo, to the west of the southern half of Lake Tanganyika. Location The highlands are divided by the Mulobozi River, which flow into the lake just north of Moba port. The northern section reaches an altitude of while the larger southern part reaches . Mean annual rainfall is around , mostly falling between October and April. The soil is relatively low in nutrients. A sublacustrine swell extends from the Marungu plateau under the southern basin of Lake Tanganyika, subdividing it into the Albertville and Zongwe basins. The Zongwe trough holds the deepest part of the lake, at below the present lake level. Alluvial cones from the rivers that drain the Marungu Plateau are present at the foot of the Zongwe trough, and there are many V-shaped valleys below the lake level. These features indicate that during the Quaternary (2.588 million years ago to the present) the lake level varied greatly, ...

Tanganyika Province
Tanganyika is one of the 21 new provinces of the Democratic Republic of the Congo created in the 2015 repartitioning. Tanganyika, Haut-Katanga, Haut-Lomami and Lualaba provinces are the result of the splitting up of the former Katanga province. Tanganyika was formed from the Tanganyika district whose town of Kalemie was elevated to capital city of the new province. The new province's territory corresponds to the historic Nord-Katanga province that existed in the early period of post-colonial Democratic Republic of the Congo between 1962 and 1966. History Tanganyika province was the scene of a rebellion by the Luba-Katanga people against the independent state of Katanga. In 1961, it was reconquered by the Katanga state, only to be taken back by the Kinshasa government later that year. From July 11, 1962, to December 28, 1966, this area was known as the province of ''Nord-Katanga'', but the administration of the province was taken over in 1966 by the central government, and i ...

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] |
Albertine Rift Montane Forests
The Albertine Rift montane forests is a tropical moist broadleaf forest ecoregion in east-central Africa. The ecoregion covers the mountains of the northern Albertine Rift, and is home to distinct Afromontane forests with high biodiversity. Geography The high montane forests cover the western portions of Rwanda and Burundi, the eastern edge of the Democratic Republic of the Congo, and portions of western Uganda and Tanzania. This area occupies the parallel Albertine Rift Mountains that enclose the western branch of the East African Rift. The mountain ranges include the Lendu Plateau of Uganda (the forest is almost completely cleared from here), and the Virunga Mountains and Rwenzori Mountains of Rwanda, Uganda, and the Democratic Republic of the Congo. At the highest elevations of the Rwenzori and Virunga ranges (above 3000 meters), the forests transition to the Afroalpine Rwenzori–Virunga montane moorlands ecoregion, including the high peaks of Mount Stanley and Mount Karisi ...
