Somali Pigeon
The Somali pigeon (''Columba oliviae'') or Somali stock dove is a species of bird in the family Columbidae. It is endemic to Somalia. Because there has hardly been any research on the species, the health of the population is uncertain; however, it is believed that the species is relatively rare. The IUCN Redlist identified a possible threat to the species from the speckled pigeon (''Columba guinea''). ''C. oliviae'' is found mostly on the ground, where it often forages, most frequently in rock along arid coasts. Taxonomy The Somali pigeon is placed in the ''Oenas'' sub-group within the genus ''Columba'' alongside the stock dove and yellow-eyed pigeon, based on their similar mauve heads and wing markings, but believed to be more closely related to the latter overall. Description ''C. oliviae'' is a mid-sized pigeon with pale grey coloration, a mauve cap, yellow eyes and an iridescent collar with bronze-green tones. It has a bluish-gray rump, dark wing edges and dark bands along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephenson Robert Clarke
Colonel Stephenson Robert Clarke (1 July 1862 – 3 November 1948) was a British Army officer, naturalist, horticulturist, and landowner. During his army posting in Africa, he collected many bird species, describing several including what is known as Clarke's weaver (''Ploceus golandi''), named after his brother Captain Goland Clarke. Clarke was born in Marylebone, London to Agnes Maria Bridger and Stephenson Clarke. He was educated at Winchester and spent some time in France where he learned French interacting with bird-catchers. After finishing school he went on a voyage to New Zealand where he collected his first bird specimens. He joined the Royal Sussex Light Infantry in 1880 and served in South Africa during which time he collected African birds. He commanded the regiment from 1906 to 1912. He was made CB in 1911. He also served in the family business of Stephenson Clarke and Company. He served as a Justice of the Peace for Sussex. Clarke described the species '' Lybius cha ...

Grains
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and milled for flour or pressed for oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains. Grains and cereal Grains and cereal are synonymous with caryopses, the fruits of the grass family. In agronomy and commerce, seeds or fruits from other plant families are called grains if they resemble caryopses. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Stephenson Robert Clarke
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1918
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Somalia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Africa
East Africa, Eastern Africa, or East of Africa, is the eastern subregion of the African continent. In the United Nations Statistics Division scheme of geographic regions, 10-11-(16*) territories make up Eastern Africa: Due to the historical Omani Empire and colonial territories of the British East Africa Protectorate and German East Africa, the term ''East Africa'' is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania, and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.Somaliland is not included in the United Nations geoscheme, as it is internationally recognized as a part of Somalia. *Tanzania, Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo and South Sudan are members of the East African Community.

List Of States With Limited Recognition
A number of polities have declared independence and sought diplomatic recognition from the international community as sovereign states, but have not been universally recognised as such. These entities often have ''de facto'' control of their territory. A number of such entities have existed in the past. There are two traditional theories used to indicate how a sovereign state comes into being. The declarative theory (codified in the 1933 Montevideo Convention) defines a state as a person in international law if it meets the following criteria: # a defined territory # a permanent population # a government, and # a capacity to enter into relations with other states. According to the declarative theory, an entity's statehood is independent of its recognition by other states. By contrast, the constitutive theory defines a state as a person of international law only if it is recognised as such by other states that are already a member of the international community.

Obverse
Obverse and its opposite, reverse, refer to the two flat faces of coins and some other two-sided objects, including paper money, flags, seals, medals, drawings, old master prints and other works of art, and printed fabrics. In this usage, ''obverse'' means the front face of the object and ''reverse'' means the back face. The obverse of a coin is commonly called ''heads'', because it often depicts the head of a prominent person, and the reverse ''tails''. In numismatics, the abbreviation ''obv.'' is used for ''obverse'',David Sear. ''Greek Imperial Coins and Their Values.'' Spink Books, 1982. p. xxxv. while ℞, )(Jonathan Edwards.

Somaliland Shilling
The Somaliland shilling ( so, Shillin Somaliland, ar, شلن صوماليلاندي; abbreviation: SLS; symbol: /-, sometimes prefixed Sl.Sh.) is the official currency of the Republic of Somaliland. Overview The shilling has been the currency of parts of Somalia since 1921, when the East African shilling was introduced to the former British Somaliland protectorate. Following the 1960 independence and unification of the former territories of British Somaliland and Italian Somaliland, their respective currencies, the East African shilling and somalo (which were equal in value) were replaced at par in 1962 by the Somali shilling. Names used for its denominations were cent (singular: centesimo; plural: centesimi) and سنت (plural: سنتيمات), along with shilling (singular: scellino; plural: scellini) and شلن. In September 1994, the Parliament of Somaliland endorsed President Egal’s plans to introduce a new currency to replace the Somali shilling. The Somaliland shil ...

African Continent
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the ÉPOQ database, created by Jacque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berries
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples are strawberries, raspberries, blueberries, blackberries, red currants, white currants and blackcurrants. In Britain, soft fruit is a horticultural term for such fruits. In common usage, the term "berry" differs from the scientific or botanical definition of a fruit produced from the ovary of a single flower in which the outer layer of the ovary wall develops into an edible fleshy portion (pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspberries, and blackberries, which are aggregate fruits and mulberries, which are mul ...
