ROOK (O.E. Hr6c, Icel. Hr6kr,1 Swed. Mika, Du. Roek, Gael. Rocas)  , the See also:Corvus frugilegus of See also:ornithology, and through-out a See also:great See also:part of See also:Europe the commonest and best-known of the See also:crow-tribe, belonging to the Passerine See also:family Corvidae . Besides its pre-eminently gregarious habits, which did not See also:escape the See also:notice of See also:Virgil (Georg. i . 382)2 and are so unlike those of nearly every other member of the Corvidae, the See also:rook is at once distinguished from the See also:rest by commonly losing at an See also:early See also:age the feathers from its See also:face, leaving a See also:bare, scabrous and greyish-See also:white skin that is sufficiently visible at some distance . In the comparatively rare cases in which these feathers persist, the rook may be readily known from the See also:black See also:form of crow (q.v.) by the See also:rich See also:purple See also:gloss of its black plumage, especially on the See also:head and See also:neck, the feathers of which are soft and not pointed . In a See also:general way the See also:appearance and See also:manners of the rook are well known, and particularly its See also:habit of forming communities in the breeding-See also:season, which it possesses in a measure beyond that of any other See also:land See also:bird of the See also:northern hemisphere . Yet each of these communities, or rookeries, seems to have some See also:custom intrinsically its own . In a general way the least-known parts of the rook's mode of See also:life are facts See also:relating to its See also:migration and See also:geographical See also:distribution . Though the great See also:majority of rooks in See also:Britain are sedentary or only See also:change their See also:abode to a very limited extent, it is now certain that a very considerable number arrive in or towards autumn, not necessarily to abide, but merely to pass onward, like most other kinds of birds, to See also:winter farther southwards; and, at the same season or even a little earlier, it cannot be doubted that a large proportion of the See also:young of the See also:year migrate in the same direction . As a See also:species the rook on the See also:European See also:continent only resides during the whole year throughout the See also:middle See also:tract of its See also:ordinary range . Farther to the northward, as in See also:Sweden and northern See also:Russia, it is a See also:regular summer-immigrant, while farther to the southward, as in See also:southern See also:France, See also:Spain and most parts of See also:Italy, it is, on the contrary, a regular winter-immigrant . The same is found to be the See also:case in See also:Asia, where it extends eastward as far as the upper Irtish and the Ob . It breeds throughout See also:Turkestan, in the See also:cold See also:weather visiting See also:Afghanistan, Cashmere and the See also:Punjab, and See also:Sir See also:Oliver St See also:John found a rookery of considerable See also:size at Casbin in See also:Persia .

In See also:

Palestine and in See also:lower See also:Egypt it is only a winter-visitant, and H . B . Tristram noticed that it congregates in great See also:numbers about the See also:mosque of See also:Omar in See also:Jerusalem . The same writer (Proc . Zool . See also:Soc., 1864, p . 444; See also:Ibis, 1866, pp . 68, 69) considered the Palestine rook entitled to specific distinction as Corvus See also:Agricola . The rook of See also:China has also been described as a distinct species, C. pastinator (Proc . Zool . Soc., 1845, p . 1) from having the feathers of its face only partially See also:deciduous .
