Regal Sunbird
The regal sunbird (''Cinnyris regius'') is a species of bird in the family Nectariniidae. It is native to the Albertine Rift montane forests. Description The regal sunbird is a small species. The adult male has head and upper parts an iridescent golden-green, dark wings and tail and a boldly-marked red and yellow breast and belly. The adult female has dull olive upper parts, with yellowish, faintly streaked underparts. The male is distinctive, but the female could be confused with the female Rockefeller's sunbird (''Cinnyris rockefelleri''), though this has a paler throat. The female Rwenzori double-collared sunbird (''Cinnyris stuhlmanni'') and the female northern double-collared sunbird (''Cinnyris reichenowi'') are also similar, but these have greener upper parts and yellower underparts; another similar species is the variable sunbird (''Cinnyris venustus''), but the regal can be recognised by the upper parts being more olive and the underparts a more uniform yellowish-olive. ...

Volcanoes National Park
Volcanoes National Park is a national park in northwestern Rwanda. It covers of rainforest and encompasses five of the eight volcanoes in the Virunga Mountains, namely Karisimbi, Bisoke, Muhabura, Gahinga and Sabyinyo. It borders Virunga National Park in the Democratic Republic of Congo and Mgahinga Gorilla National Park in Uganda. It is home to the mountain gorilla and the golden monkey, and was the base for the primatologist Dian Fossey. History The park was first gazetted in 1925, as a small area bounded by Karisimbi, Bisoke and Mikeno, intended to protect the gorillas from poachers. It was the very first National Park to be created in Africa. Subsequently, in 1929, the borders of the park were extended further into Rwanda and into the Belgian Congo, to form the Albert National Park, a huge area of 8090 km2, run by the Belgian colonial authorities who were in charge of both colonies. In 1958, 700 hectares of the park were cleared for a human settlement. Between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rwanda
Rwanda (; rw, u Rwanda ), officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of Central Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of a thousand hills", with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. Rwanda has a population of over 12.6 million living on of land, and is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the fifth most densely populated country in the world. One million people live in the capital and largest city Kigali. Hunter-gatherers settled the territory in the Stone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the '' Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, ... [...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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 s ... [...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 Mou ...

Rockefeller's Sunbird
Rockefeller's sunbird (''Cinnyris rockefelleri'') is a species of bird in the family Nectariniidae. Taxonomy This species is part of a larger radiation of sunbirds within the genus ''Cinnyris''. Like other members of this genus, it was formerly considered part of the genus ''Nectarinia''. Distribution and habitat This species is only known from the Albertine Rift in eastern Democratic Republic of the Congo, where it is found in montane forest between 2000-3300 m in elevation. Sight records of this species exist from Rwanda and Burundi, but these lack documentation and have yet to be confirmed. 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 dead, thereby .... References Rockefeller's sunbird Rockefeller's sunbird Rockefeller's sunbird Tax ...

Rwenzori Double-collared 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 sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Double-collared Sunbird
The northern double-collared sunbird (''Cinnyris reichenowi''), is a species of bird in the family Nectariniidae. It is found in Burundi, Cameroon, Central African Republic, Democratic Republic of the Congo, Equatorial Guinea, Kenya, Nigeria, Rwanda, South Sudan, and Uganda. Description The northern double-collared sunbird is a medium-sized species. The adult male's head and back is a metallic green that has a steely-blue sheen in some lights. The rump is greyish-brown, the uppertail coverts metallic purple and the tail black, glossed blue. The main flight feathers are dark brown. There is a narrow purple collar beneath the metallic green throat, above a scarlet breast and pale brown belly. There are pale yellow that are not always visible. The eye is black or dark brown, and the beak and legs are black. The adult female is more drab with upper parts dark olive green and a dark brown tail. The underparts are greyish-olive, the belly being tinged with yellow. The juvenile is simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Sunbird
The variable sunbird or yellow-bellied sunbird (''Cinnyris venustus''), formerly ''Nectarinia venusta'', is a sunbird. The sunbirds are a group of 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 most of the time. The variable sunbird is a fairly common resident breeder in equatorial Africa. Two eggs are laid in a suspended nest in a tree. This species is found in open woodland and cultivation. Variable sunbirds are small, only 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding. The adult male has a glossy green head, throat and nape, and a maroon breast band. In most subspecies In biological classification, subspecies is a rank below species, used for populations that li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...
