THE ROOK. (Corvus frugilegus.)
The cawing of these birds, on the tops of high trees near gentlemen’s houses, and in the middle of cities, is not very pleasing; yet old habits, to which we are reconciled, have as much influence upon us as if they were productive of amusement. Hence it has been seldom attempted to destroy a rookery; although the noise and other inconveniences that accompany these birds render their vicinity often troublesome. They feed entirely on corn and insects, and are little bigger than the common crows. In Suffolk, and in some parts of Norfolk, the farmers find it their interest to encourage the breed of Rooks, as the only means of freeing their grounds from the grub, which produces the cockchafer, and which in this state destroys the roots of corn and grass to such a degree, that instances have been known where the turf of pasture land might be turned up with the foot. The farmers in a northern county, a good many years ago, waged a war of extermination against the Rooks, but the very next year the crops were so completely cut up by grubs, that the same proprietors were at considerable expense in getting Rooks back again. Young Rooks are good eating, but should be skinned before they are dressed. The colour is black, but brighter than that of the crow, which the Rook resembles in shape. The female lays the same number of eggs; and the male shares with her the trouble of fetching sticks, and interweaving them to make the nest, an operation which is attended with a great deal of fighting and disputing with the other Rooks.
New comers are often severely beaten by the old inhabitants, and are even frequently driven quite away; of this an instance occurred near Newcastle, in the year 1783. A pair of Rooks, after an unsuccessful attempt to establish themselves in a rookery at no great distance from the Exchange, were compelled to abandon the attempt, and take refuge on the spire of that building; and, though constantly interrupted by other Rooks, they built their nest on the top of the vane, and reared their young ones, undisturbed by the noise of the populace below. The nest and its inhabitants were of course turned about by every change of the wind! They returned and built their nest every year on the same place, till 1793, soon after which year the spire was taken down. A small copperplate was engraved, of the size of a watchpaper, with a representation of the spire and the nest; and so much pleased were the inhabitants and other persons with it, that as many copies were sold as produced to the engraver a profit of ten pounds. The woodcut by Bewick, in the title-page to his Select Fable gives, a view of the old Exchange, with the Rook’s nest on the vane.
It is amusing to see Rooks coming at sunset as thick as a cloud hovering over a grove, and, after several eddies described in the air, and incessant cawings, each repairing to its own nest, and settling in a few minutes to rest, till the dawn calls them up again to their pasture in the neighbouring fields.
Dr. Darwin has remarked, that an instinctive feeling of danger from mankind is much more apparent in Rooks than in most other birds. Any one who has in the least observed them will see that they evidently distinguish that the danger is greater when a man is armed with a gun, than when he has no weapon with him. In the spring of the year, if a person happened to walk under a rookery with a gun in his hand, the inhabitants of the trees rise on their wings, and scream to the unfledged young to shrink into their nests from the sight of the enemy. The country people observing this circumstance so uniformly to occur, assert that Rooks can smell gunpowder.
