Since rabbits are prey animals, they are careful in open spaces. If they sense danger, they freeze and watch. Rabbit vision has a very wide field, including overhead scanning. Their enemies are foxes and dogs; also bears, raccoons, minks, weasels and snakes. Birds of prey sometimes take rabbits. People are also known to shoot rabbits, because they eat crops. Their escape method is to run for their burrow, where they are usually safe.
