JACKDAW , or simply DAw (Old See also:

Low See also:German, Daha; Dutch, Kaauw), one of the smallest See also:species of the genus See also:Corvus (see See also:CROW), and a very well known inhabitant of See also:Europe, the C. monedula of ornithologists. In some of its habits it much resembles its congener the See also:rook, with which it constantly associates during a See also:great See also:part of the See also:year; but, while the rook only exceptionally places its See also:nest elsewhere than on the boughs of trees and open to the See also:sky, the daw almost invariably chooses holes, whether in rocks, hollow trees, See also:rabbit-burrows or buildings. Nearly every See also:church-See also:tower and See also:castle, ruined or not, is more or less numerously occupied by daws. Chimneys frequently give them the See also:accommodation they See also:desire, much to the annoyance of the householder, who finds the See also:funnel choked by the quantity of sticks brought together by the birds, since their See also:industry in See also:collecting materials for their nests is as marvellous as it often is futile. In some cases the stack of loose sticks piled up by daws in a See also:belfry or tower has been known to See also:form a structure 10 or 12 ft. in height, and hence this species may be accounted one of the greatest nest-builders in the See also:world. The See also:style of See also:architecture practised by the daw thus brings it more than the rook into contact with See also:man, and its familiarity is increased by the boldness of its disposition which, though tempered by discreet cunning, is hardly surpassed among birds. Its small See also:size, in comparison with most of its congeners, alone incapacitates it from inflicting the serious injuries of which some of them are often the authors, yet its pilferings are not to be denied, though on the whole its services to the agriculturist are great, for in the destruction of injurious See also:insects it is hardly inferior to the rook, and it has the useful See also:habit of See also:ridding See also:sheep, on whose backs it may be frequently seen perched, of some of their parasites. The daw displays the glossy See also:black plumage so characteristic of the true crows, varied only by the hoary See also:grey of the See also:ear-coverts, and of the nape and sides of the See also:neck, which is the See also:mark of the adult; but examples from the See also:east of Europe and western See also:Asia have these parts much lighter, passing into a silvery See also:white, and hence have been deemed by some authorities to constitute a distinct species (C. collaris, Drumm.). Further to the east-See also:ward occurs the C. dauuricus of See also:Pallas, which has not only the See also:collar broader and of a pure white, but much of the See also:lower parts of the See also:body white also. See also:Japan and See also:northern See also:China are inhabited also by a form resembling that of western Europe, but wanting the grey nape of the latter. This is the C. neglectus of See also:Professor See also:Schlegel, and is said by See also:Dresser, on the authority of Swinhoe, to interbreed frequently with C. dauuricus. These are all the birds that seem entitled to be considered daws, though Dr See also:Bowdler See also:Sharpe (See also:Cat.

B. Brit. Museum, iii. 24) associates with them (under the little-deserved See also:

separate generic distinction Coloeus) the See also:fish-crow of See also:North See also:America, which appears both in structure and in habits to be a true crow. (A.
