Bats are the only flying mammals in the world. They can't see very well. It was long believed, and still is in many places, that all bats are blind. “Blind as a bat” is often heard. Yet they have no trouble flying in the darkest nights and finding their way around very well. How can bats fly and see at night? They fly by radar. The bat's radar system works the same way as the one that ships and planes use. As a bat flies through the air, he makes a sound that is too high for our ears to hear. If the sounds hit things they come back. The bat's ears receive the messages. In this way they are able to tell the bat where the things are. Bats go out to look for food at night. In the daytime they hang in some dark places. Some people have the bats as bad animals. In fact they are useful animals.
