By Mrs. Wojciechowski Big Brown Bats like to live alone. They hibernate at the entrance to caves in the winter. If they cannot find a cave, they will hibernate in mines, hollow trees, and in the empty spaces in cliffs. Big Brown Bats are found all over the United States and Mexico. These are the kind of bats you might find in your attic.
Many bats have unique faces and ears.
Some people think that bats are ugly. Actually, bats have adapted to their environment. Their appearance helps them with their echolocation. The shape of the bats nose and mouth helps them to communicate. They close their mouths and produce sounds like a hum.
