The Weasel is a good climber, and makes use of its skill in this accomplishment to prey upon birds, their eggs, and young. Rats and Mice are, perhaps, its staple food. Of these it makes great havoc, and is therefore a useful hanger-on to the farm-yard, notwithstanding its occasional depredations in the hen-roost. When it catches a Mouse or Rat, it gives it one bite on the back of the head, piercing the most vulnerable part of the brain, and killing instantly. Professor Thomas Bell says:--“I have observed that when a Weasel seizes a small animal, at the instant that the fatal bite is inflicted, it throws its long, lithe body over its prey, so as to secure it should the first bite fail, an accident, however, which I have never observed when a Mouse has been the victim. The power which the Weasel has of bending the head at right angles with the long and flexible, though powerful neck, gives it a great advantage in this mode of seizing and killing its smaller prey.” The first part eaten is usually the brain. The stories of the Weasel’s blood-sucking propensities are probably false, or at any rate grossly exaggerated. The Weasel will pursue its prey over fields, in trees, in subterranean burrows, or across water. Like many of the wild Cats, it kills far more than is necessary for its support, and in pursuance of its favourite occupation of slaughter shows an unequalled courage and pertinacity. Its power of keeping its presence of mind under very trying circumstances is well shown in the following anecdote related by Bell:--A gentleman, “while riding over his grounds, saw at a short distance from him a Kite pounce on some object on the ground, and rise with it in his talons. In a few moments, however, the Kite began to show signs of great uneasiness, rising rapidly in the air, or as quickly falling, and wheeling irregularly round, whilst it was evidently endeavouring to force some obnoxious thing from it with its feet. After a sharp but short contest, the Kite fell suddenly to the earth, not far from where Mr. Pindar was intently watching the manœuvre. He instantly rode up to the spot, when a Weasel ran away from the Kite, apparently unhurt, leaving the bird dead, with a hole eaten through the skin under the wing, and the large blood-vessels of the part cut through.” THE ERMINE.[171]
