The cunning of rooks, crows, and magpies is very marked at nesting-time; and the keeper who would shoot them by hiding and waiting within shot of their nests may wait for hours in vain if the birds have seen him approach--as they seldom fail to do. The birds are cunning enough to watch from the top of a tall, distant tree, until they see the enemy go away, when they will return at once to the nest in full confidence. But they may be tricked quite easily. Let two men with a gun go together to stand below a rook's nest. Away go the nesting birds. Then let one of the men take his departure, with or without the gun, while the other waits. The birds will return promptly, as though they imagined both men had gone. The keeper has small sympathy with the crow tribe, and takes every opportunity to reduce their numbers. Sometimes he will carry a ferret to an open spot, over which crows or others are likely to fly, peg the ferret down, and himself lie in wait with a gun. No rook, crow, magpie or jay can resist the temptation to mob the ferret. So the keeper takes advantage of the widespread bird-hatred of the weasel tribe. He traces a lost and wandering ferret by the wild clamouring of the jays that have caught sight of the bloodthirsty creature, or by hints from other birds, great and small. * * * * * The Crow as Terrorist Carrion crows hold mysterious sway over rooks; a single pair of crows will drive a great crowd of rooks from a rookery. Yet a crow, when compared to a rook, does not seem to be much more powerful or armed with a much more formidable beak. A casual observer would find little difference between a rook and a crow in the hand. If a pair of crows were pitted in a duel against a pair of rooks, the balance of power would make the odds slightly in the crows' favour no doubt. But one imagines the rooks would still have a sporting chance. Probably crows have a black enough reputation among other birds to inspire a general fear. And rooks are cowards. It is a common sight to see them put to shameful flight by peewits or missel-thrushes when they have ventured near the others' nesting-places. Yet a rook could kill a missel-thrush or peewit if it had the pluck to fight. The gamekeeper knows that the hissing and spitting of a sitting partridge will cause a rook to approach her very cautiously. A jackdaw, one would say, has ten times the spirit of a rook. * * * * * Imperial Rooks
