Jackdaw
Jackdaws are two species of bird in the genus ''Coloeus'' closely related to, but generally smaller than, crows and ravens ('' Corvus''). They have a blackish crown, wings, and tail, with the rest of their plumage paler.Madge & Burn (1994) 136–138. The word ''Coloeus'' is Neo-Latin, from the Ancient Greek for jackdaws: ' (). They come from Asia, Europe, Africa and Siberia (the one not in Asia?). Taxonomy While some authors consider ''Coloeus'' a subgenus of ''Corvus'', others have classified ''Coloeus'' as a distinct genus in the family Corvidae. Following '' Birds of South Asia: The Ripley Guide'', the International Ornithological Congress has also reassigned the two Jackdaw species from the genus ''Corvus'' to the genus ''Coloeus''. Species The eastern species is smaller than the western jackdaw, and in eastern adults, the pale areas of the plumage are almost white, whereas in the western bird, these areas are pale grey. The iris is pale in western jackdaw and dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Jackdaw
The western jackdaw (''Coloeus monedula''), also known as the Eurasian jackdaw, the European jackdaw, or simply the jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and western North Africa; it is mostly resident, although northern and eastern populations migrate south in the winter. Four subspecies are recognised, which differ mainly in the colouration of the plumage on the head and nape. Linnaeus first described it formally, giving it the name ''Corvus monedula''. The common name derives from the word ''jack'', denoting "small", and daw, a less common synonym for "jackdaw", and the native English name for the bird. Measuring in length, the western jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. Like its relatives, jackdaws are intelligent birds, and ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crow
A crow is a bird of the genus ''Corvus'', or more broadly, a synonym for all of ''Corvus''. The word "crow" is used as part of the common name of many species. The related term "raven" is not linked scientifically to any certain trait but is rather a general grouping for larger-sized species of ''Corvus''. The collective name for a group of crows is a "murder". Species * ''Corvus albus'' – Pied crow (Central African coasts to southern Africa) * ''Corvus bennetti'' – Little crow (bird), 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
''Corvus'' is a widely distributed genus of passerine birds ranging from medium-sized to large-sized in the family Corvidae. It includes species commonly known as crows, ravens, and rooks. The species commonly encountered in Europe are the carrion crow, hooded crow, common raven, and 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 "raven". The 46 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Coloeus Dauuricus
The Daurian jackdaw (''Coloeus dauuricus'') is a bird in the crow family, Corvidae, native to eastern Asia. It is closely related to the western jackdaw. The name derives from the Dauria region of eastern Russia. Description At about in length, the Daurian jackdaw is about the same size as or slightly smaller than the western jackdaw, with the same proportions and identical habits. The principal difference lies in the plumage; many but not all adults have large areas of creamy white on the lower parts extending up around the neck as a broad collar. The head, throat, wings, and tail are glossy black and the ear coverts are grizzled grey. Darker adults and young birds resemble western jackdaws, though Daurian jackdaws have black irises, unlike the distinctive grey-white irises of the Eurasian jackdaw. The only other pied corvid species inhabiting the same region is the Chinese collared crow (''Corvus torquatus''), but as this is a much larger bird (about the same size or slightly ...
