Many people must have been visited by a bat in their drawing  room or bedroom at one time or another, and if they have not been“to scared of it, they will have been fascinated by its swift, skilful flight and the rapid twists and turns with which it avoids all. obstacles, including objects like shoes and towels that are hurled at it. Now despite the old saying. bats are not blind. They have perfectly good eyes, but these are so tiny that they are not easily detected. Their eyes are certainly not good enough for them to perform some of the extraordinary flying, stunts in which they indulge. It was an italian naturalist called Spallanzani. in the eighteenth century who first started to investigate the flight of bats and by the unnecessarily cruel method of blinding several bats. he found that they could still fly about unhampered, avoiding obstacles as though they were uninjured. But how they managed to do this he could not guess.
