Bats hang upside down when they are resting. Vampire bats include a few kinds of bats that feed on the blood of other animals. The common vampire bat lives in Central and South America. It preys mainly on cattle. It sometimes bites human beings, but such incidents are rare.
Vampire bats approach their prey on foot.
They scoop out a small piece of the victim's skin with their sharp teeth and then lick blood from the wound. The wound they give their victims heals quickly, but these bats may carry rabies. During the Middle Ages it was believed that witches could turn themselves into black cats. Thus when such a cat was seen, it was considered to be a witch in disguise. The lights from those fires can be seen on Oct 31 if you stand at the edge of those forests.
