How can I listen to bats?
To listen to bats you need to use a bat detector. This device take the high pitched echolocation cries of bats and lowers their frequency so that we can hear them. Bat detectors are available through Bat Conservation International (www.batcon.org) and other companies and organizations. You might ask your science teacher to see if your school has one.
