Somali Crow
The Somali crow, or dwarf raven (''Corvus edithae''), is approximately the size (44β46 cm in length) of the carrion crow, ''Corvus corone'' but with a longer bill and a somewhat more brownish cast to the feathers, especially when worn. Distribution and Species This species occurs principally in Somalia, Djibouti, the Ogaden and the Northern Frontier District in the Horn of Africa, and can be distinguished from the larger brown-necked raven ''C. ruficollis'' by its call, appearance and differences in its behaviour. It was formerly considered a subspecies of the larger brown-necked raven (''C. ruficollis''), but is now considered to be a distinct species. This crow is thought to be closer to the pied crow ''C. albus'' by some authorities, especially in its behaviour, than to the brown-necked raven. Hybrid birds between the pied crow and the Somali crow appear to reinforce this close relationship where the two species meet. The nest is a ravenlike bulky structure set in eit ...

Carrion Crow
The carrion crow (''Corvus corone'') is a passerine bird of the family Corvidae and the genus ''Corvus'' which is native to western Europe and the eastern Palearctic. Taxonomy and systematics The carrion crow was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', and it still bears its original name of ''Corvus corone''. The binomial name is derived from the Latin , "raven", and Greek , "crow". The hooded crow, formerly regarded as a subspecies, has been split off as a separate species, and there is some discussion whether the eastern carrion crow (''C. c. orientalis'') is distinct enough to warrant specific status; the two taxa are well separated, and it has been proposed they could have evolved independently in the wetter, maritime regions at the opposite ends of the Eurasian landmass.Madge, Steve & Burn, Hilary (1994): ''Crows and jays: a guide to the crows, jays and magpies of the world''.

The country is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the north, the Indian Ocean to the east, and Kenya to the southwest. Somalia has the longest coastline on Africa's mainland. Its terrain consists mainly of plateaus, plains, and highlands. Hot conditions prevail year-round, with periodic monsoon winds and irregular rainfall. Somalia has an estimated population of around million, of which over 2 million live in the capital and largest city Mogadishu, and has been described as Africa's most culturally homogeneous country. Around 85% of its residents are ethnic Somalis, who have historically inhabited the country's north. Ethnic minorities are ...

Djibouti
Djibouti, ar, Ψ¬ΩΨ¨ΩΨͺΩ ', french: link=no, Djibouti, so, Jabuuti officially the Republic of Djibouti, is a country in the Horn of Africa, bordered by Somalia to the south, Ethiopia to the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden to the east. The country has an area of . In antiquity, the territory, together with Ethiopia, Eritrea and Somaliland, was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French, and its railroad to Dire Dawa (and later Addis Ababa) allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was renamed the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the ''Rep ...

Ogaden
Ogaden (pronounced and often spelled ''OgadΔn''; so, Ogaadeen, am, ααα΄/ααα΄α) is one of the historical names given to the modern Somali Region, the territory comprising the eastern portion of Ethiopia formerly part of the Hararghe province. The other two names are the Haud and Reserved area. Etymology The origin of the term ''Ogaden'' is unknown, however it is usually attributed to the Somali clan of the same name, originally referring only to their land, and eventually expanding to encompass most parts of the modern Somali Region of Ethiopia. During the new region's founding conference, which was held in Dire Dawa in 1992, the naming of the region became a divisive issue, because almost 30 Somali clans live in the Somali Region of Ethiopia. The ONLF sought to name the region βOgadeniaβ, whilst the non-Ogadeni Somali clans who live in the same region opposed this move. As noted by Abdul Majid Hussein, the naming of the region where there are several Somal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Eastern Province (Kenya)
The North Eastern Province ( so, Gobolka Woqooyi Bari, πππππππ ππππππ ππππ) is one of the former provinces in Kenya. It has a land area of 127,358.5 km2, with its capital at Garissa. Previously known as the Northern Frontier District (NFD), the North Eastern Province territory was carved out of the present-day southern Somalia during the colonial period. However, during negotiations for Kenya's independence, Britain granted administration of the NFD to Kenyan nationalists despite an informal plebiscite showing the overwhelming desire of the region's population to join the newly formed Somali Republic. It is, and has historically been, mostly inhabited by ethnic Somalis.Rhoda E. Howard, ''Human Rights in Commonwealth Africa'', (Rowman & Littlefield Publishers, Inc.: 1986), p.95 History The Northern Frontier District came into being in 1925, when it was carved out of the present-day southern Somalia.

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 Ethiopia, Eritrea, Somalia and Djibouti; broader definitions also include parts or all of Kenya, Sudan, South Sudan, and Uganda. The term Greater Horn Region (GHR) can additionally include Burundi, Rwanda, and Tanzania. It lies along the southern boundary of the Red Sea and extends hundreds of kilometres into the Guardafui Channel, Gulf of Aden, and Indian Ocean and shares a maritime border with the Arabian Peninsula of Western Asia. Names This peninsula has been known by various names. Ancient Greeks and Romans referred to it as Regio Aromatica or Regio Cinnamonifora due to the aromatic plants or as Regio I ...

Brown-necked Raven
The brown-necked raven (''Corvus ruficollis'') is a larger bird (52β56 cm in length) than the carrion crow though not as large as the common raven. It has similar proportions to the common raven but the bill is not so large or deep and the wings tend to be a little more pointed in profile. The head and throat are a distinct brownish-black giving the bird its English name, while the rest of the plumage is black glossed with purple, blue or purplish-blue. Like the common raven, thick-billed raven and white-necked raven, it is one of the larger raven species. The feathers of this species often fade quite quickly to a brownish black (even the truly black feathers) and the bird can look distinctly brown by the time it moults. The feet, legs and bill are black. The dwarf raven was formerly considered a subspecies (''Corvus ruficollis edithae'') but this bird now appears to be closer to the pied crow (''C. albus'') than this species. Distribution and habitat This species has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pied Crow
The pied crow (''Corvus albus'') is a widely distributed African bird species in the crow genus. Structurally, the pied crow is better thought of as a small crow-sized raven, especially as it can hybridise with the Somali crow (dwarf raven) where their ranges meet in the Horn of Africa. Its behaviour, though, is more typical of the Eurasian carrion crows, and it may be a modern link (along with the Somali crow) between the Eurasian crows and the common raven. Description It is approximately the size of the European carrion crow or a little larger (46β50 cm in length) but has a proportionately larger bill, slightly longer tail and wings, and longer legs. As its name suggests, its glossy black head and neck are interrupted by a large area of white feathering from the shoulders down to the lower breast. The tail, bill and wings are black too. The eyes are dark brown. The white plumage of immature birds is often mixed with black. It resembles the white-necked and thick-billed ...

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvus
''Corvus'' is a widely distributed genus of medium-sized to large birds in the family Corvidae. It includes species commonly known as crows, ravens and Rook (bird), rooks. The species commonly encountered in Europe are the carrion crow, the hooded crow, the common raven and the rook (bird), rook; those discovered later were named "crow" or "raven" chiefly on the basis of their size, crows generally being smaller. The genus name is Latin for "crow". The List of Corvus species, 45 or so members of this genus occur on all temperate continents except South America, and several islands. The ''Corvus'' genus makes up a third of the species in the family Corvidae. The members appear to have evolved in Asia from the corvid stock, which had evolved in Australia. The collective noun, collective name for a group of crows is a "flock" or a "murder". Recent research has found some crow species capable of not only Tool use by animals, tool use, but also tool construction. Crows are now consi ...
