Cyanomitra Olivacea
The olive sunbird (''Cyanomitra olivacea'') is a species of sunbird found in a large part of Africa south of the Sahel. It prefers forested regions, and is absent from drier, more open regions such as the Horn of Africa and most of south-central and south-western Africa. It is sometimes placed in the genus ''Nectarinia''. The western subspecies (roughly west of the East African Rift) are sometimes split as the western olive sunbird, ''Cyanomitra obscura'', in which case ''Cyanomitra olivacea'' becomes the eastern olive sunbird References Further reading * External links * Olive sunbird Species text in The Atlas of Southern African Birds Cyanomitra Birds of the Gulf of Guinea Birds of Sub-Saharan Africa Birds described in 1840 Taxonomy articles created by Polbot {{Nectariniidae-stub ...

Andrew Smith (zoologist)
Sir Andrew Smith (3 December 1797 – 11 August 1872) was a British surgery, surgeon, explorer, ethnologist and zoology, zoologist. He is considered the father of zoology in South Africa having described many species across a wide range of groups in his major work, ''Illustrations of the Zoology of South Africa''. Smith was born in Hawick, Roxburghshire. He qualified in medicine at the University of Edinburgh obtaining an Doctor of Medicine, M.D. degree in 1819, having joined the Army Medical Services in 1816. South Africa 1820–1837 In 1820 he was ordered to the Cape Colony and was sent to Grahamstown to supervise the medical care of European soldiers and soldiers of the Cape Corps. He was appointed the Albany district surgeon in 1822 and started the first free dispensary for indigent patients in South Africa. He led a scientific expedition into the interior and was able to indulge in his interests of natural history and anthropology. On several occasions, he was sent by gov ...

Sunbird
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 152 species in 16 genera. Their family name is from most sunbirds feeding largely on nectar, but they will also catch 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Sahel
The Sahel region (; ), or Sahelian acacia savanna, is a Biogeography, biogeographical region in Africa. It is the Ecotone, transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a Semi-arid climate#Hot semi-arid climates, hot semi-arid climate and stretches across the tropics, southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea. Although geographically located in the tropics, the Sahel does not have a tropical climate. Especially in the western Sahel, there are droughts in the Sahel, frequent shortages of food and water due to its very high Corruption Perceptions Index, government corruption and the semi-arid climate. This is exacerbated by very high list of countries by birth rate, birthrates across the region, resulting in a rapid increase in population.

Horn Of Africa
The Horn of Africa (HoA), also known as the Somali Peninsula, is a large peninsula and geopolitical region in East Africa.Robert Stock, ''Africa South of the Sahara, Second Edition: A Geographical Interpretation'', (The Guilford Press; 2004), p. 26 Located on the easternmost part of the African mainland, it is the fourth largest peninsula in the world. It is composed of Somaliland, Somalia, Djibouti, Ethiopia, and Eritrea. Although not common, broader definitions include parts or all of Kenya and Sudan.John I. Saeed, ''Somali'' – Volume 10 of London Oriental and African language library, (J. Benjamins: 1999), p. 250.Sandra Fullerton Joireman, ''Institutional Change in the Horn of Africa'', (Universal-Publishers: 1997), p.1: "The Horn of Africa encompasses the countries of Ethiopia, Eritrea, Djibouti, and Somalia. These countries share similar peoples, languages, and geographical endowments." It has been described as a region of geopolitical and strategic importance, since it ...

East African Rift
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African plate is in the process of splitting into two tectonic plates, called the Somali plate and the Nubian plate, at a rate of per year. The rift system consists of three microplates, the Victoria microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Many of the African Great Lakes lie within the Rift Valley. Extent A series of distinct rift basins, the East A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanomitra
''Cyanomitra'' is a genus of African sunbirds. Its members are sometimes included in ''Nectarinia''. 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 most of the time. Taxonomy The genus ''Cyanomitra'' was introduced in 1853 by the German naturalist Ludwig Reichenbach. The name combines the Ancient Greek ''kuanos'' meaning "dark-blue" with ''mitra'' meaning "head-band". The type species was designated by George Robert Gray in 1855 as ''Certhia cyanocephala'' Shaw. This taxon is now considered to be a subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphol ...
