Carnivore The weasel has a tiny face, sharp teeth and claws, and a tail with black fur at the tip. In winter it is white and in summer it is brown. It hunts for rabbits, rats, birds, frogs, ground squirrels and pika ( a small rodent that lives in the mountains) . It eats hundreds of meadow mice. Weasels that live in the north also feed on Arctic hare and lemming.The weasel may be small but it is a good fighter and moves in a flash. It is a silent hunter and can approach without a sound, then rush upon its prey.
