Crow Business Solutions MENA
A crow is a bird of the genus '' Corvus'', or more broadly a synonym for all of ''Corvus''. Crows are generally black in colour. The word "crow" is used as part of the common name of many species. The related term "raven" is not pinned scientifically to any certain trait, but is rather a general grouping for larger ''Corvus spp.'' Species * ''Corvus albus'' – pied crow (Central African coasts to southern Africa) * ''Corvus bennetti'' – little crow (Australia) * ''Corvus brachyrhynchos'' – American crow (United States, southern Canada, northern Mexico) * ''Corvus capensis'' – Cape crow or Cape rook (Eastern and southern Africa) * ''Corvus cornix'' – hooded crow (Northern and Eastern Europe and Northern Africa and Middle East) * ''Corvus corone'' – carrion crow (Europe and eastern Asia) *''Corvus culminatus'' – Indian jungle crow (South Asia) * ''Corvus edithae'' – Somali crow or dwarf raven (eastern Africa) * ''Corvus enca'' – slender-billed crow (Malaysi ...

Corvus Corone -near Canford Cliffs, Poole, England-8
''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 rooks. The species commonly encountered in Europe are the carrion crow, the hooded crow, the common raven and the 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 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 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, but also tool construction. Crows are now considered to be among the world's most intelligent animals with an encephalization quotie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

House Crow
The house crow (''Corvus splendens''), also known as the Indian, greynecked, Ceylon or Colombo crow, is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping. It is between the jackdaw and the carrion crow in size ( in length) but is slimmer than either. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in colour. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of colour in areas of the plumage. Taxonomy The nominate race ''C. s. splendens'' is found in Pakistan, India, Nepal and Bangladesh and has a grey neck collar. The subspecies ''C. s. zugmayeri'' is found in the dry parts of South Asia and Iran and has a very pale neck collar. The subspecies ''C. s. protegatus'' is found in southern India, the Maldives (sometimes separated as ''maledivicus'') and Sri Lanka ...

Sinaloa Crow
The Sinaloa crow (''Corvus sinaloae'') is a crow native to western Mexico. Description Visually, it is nearly identical to and the same length (34–38 cm) as the Tamaulipas crow (''Corvus imparatus''). It has the same purple-glossed, silky, black plumage with a black bill, legs, and feet. The two species differ markedly in voice. Distribution and habitat It occurs on the Pacific slope from southern Sonora south to Manzanillo. The crow inhabits coastal regions where it forages on the seashore, semi-desert, open woodlands, river banks and hills up to 300 metres or more. It is very common around coastal towns and villages. Diet Food is taken both on the ground and in trees. On the seashore it can be found turning over objects to find its food and it will take a wide range of invertebrates such as small shellfish, crabs, and insects. Fruits of many types are also taken and eggs and nestlings are also on the menu when opportunity arises. Breeding Often, this bird will nest in a th ...

Palm Crow
The palm crow (''Corvus palmarum'') is a relatively small corvid that occurs on the Caribbean island of Hispaniola (Haiti and the Dominican Republic) and Cuba, where it was formerly very frequent, but is now reduced in population. Taxonomy The Cuban subspecies is slightly smaller, and is usually separated as a subspecies (''Corvus palmarum minutus''); the Hispaniolan subspecies' trinomial is ''Corvus palmarum palmarum'' (the nominate subspecies). Both subspecies are usually now given the respective common names of Hispaniolan palm crow and Cuban palm crow to distinguish them. Despite being sympatric with the white-necked crow (''Corvus leucognaphalus'') on Hispaniola, it appears to be more closely related to the fish crow (''C. ossifragus'') of the East Coast of the United States, as well as two smaller species, the Tamaulipas crow (''C. imparatus'') and Sinaloan crow (''C. sinaloae'') of Mexico, than the white-necked crow, which is more related to the Cuban crow (''Corvu ...

Fish Crow
The fish crow (''Corvus ossifragus'') is a species of crow associated with wetland habitats in the eastern and southeastern United States. Taxonomy and etymology The fish crow was given its binomial name by the Scottish ornithologist Alexander Wilson in 1812, in the fifth volume of his ''American Ornithology''. The binomial is from Latin; ''Corvus'' means "raven", while ''ossifragus'' means "bone-breaker". It is derived from ''os'' or ''ossis'', meaning "bone", and ''frangere'', meaning "to break". The English-language common name ''fish crow'' also derives from Wilson, who ascribed the name to the crow's aquatic diet, as described to him by local fishermen. He distinguished the fish crow from John Bartram's ''great seaside crow'' by the former's diminutive size when compared to the American crow. The fish crow's taxonomic relation to other species of the ''Corvus'' genus is still poorly understood, but DNA sequencing indicates that it is most closely related to the palm cro ...

Torresian Crow
The Torresian crow (''Corvus orru''), also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises. The base of the feathers on the head and neck are white. The Torresian crow is slightly larger with a more robust bill than the morphologically similar little crow. Taxonomy The Torresian crow was described by the French ornithologist Charles Lucien Bonaparte in 1850. The origin of the specific epithet ''orru'' is not known but may be derived from a Papuan name. There are three subspecies: * ''C. o. latirostris'' Meyer, AB, 1884 – east Lesser Sunda Islands * ''C. o. orru'' Bonaparte, 1850 – Maluku Islands, New Guinea, D'Entrecasteaux Islands. and Louisiade Archipelago * ''C. o. cecilae'' Mathews, 1912 – west, central and northern Australia The Bismarck crow (''Corvus insulari ...

Cuban Crow
The Cuban crow (''Corvus nasicus'') is one of four species of crow that occur on islands in the Caribbean. It is closely related to the white-necked crow (''C. leucognaphalus'') and Jamaican crow (''C. jamaicensis''), with which it shares similar features. The fourth Caribbean crow, the palm crow (''C. palmarum''), is a later arrival in evolutionary terms, and shows characteristics more akin to North American species, such as the fish crow (''C. ossifragus''), which it is probably closely related to. Distribution and habitat It can be found quite commonly over most of the large island of Cuba and on the nearby Isla de la Juventud (as well as the Turks and Caicos islands) in woodland and areas that have been cleared for agriculture. It is frequently found around farms and villages where it seems to have adapted quite well to living in relatively close contact with human settlements.

New Caledonian Crow
The New Caledonian crow (''Corvus moneduloides'') is a medium-sized member of the family Corvidae, native to New Caledonia. The bird is often referred to as the 'qua-qua' due to its distinctive call. It eats a wide range of food, including many types of invertebrates, eggs, nestlings, small mammals, snails, nuts and seeds. The New Caledonian crow sometimes captures grubs in nooks or crevices by poking a twig at the grub to agitate it into biting the twig, which the crow then withdraws with the grub still attached. This method of feeding indicates the New Caledonian crow is capable of tool use. They are also able to make hooks. This species is also capable of solving a number of sophisticated cognitive tests which suggest that it is particularly intelligent. As a result of these findings, the New Caledonian crow has become a model species for scientists trying to understand the impact of tool use and manufacture on the evolution of intelligence.

Large-billed Crow
The large-billed crow (''Corvus macrorhynchos''), formerly referred to widely as the jungle crow, is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill, which is the source of its scientific name ''macrorhynchos'' (Ancient Greek for "large beak") and it is sometimes known by the common name thick-billed crow. It can also be mistaken for a common raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827. The eastern jungle crow and Indian jungle crow were once considered conspecific and together called the jungle crow. Subspecies It has nine subspecies, and some of them are distinctive vocally, Morphology (biology), morphologically and Genetics, genetically, leading to treatments that raise some of them into species status.Madge, S.
