Detailed Description

Do you have what it takes to be a bat biologist? USGS bat researchers are counting Townsend’s big eared bats to monitor how their populations are doing. Watch the video to try your hand at a bat count and see how your skills compare to a USGS scientist! You don’t need sound to count the bats—but if you turn your sound on you’ll be able to hear the bats’ echolocation calls while you count! The calls, which sound like clicks, were picked up by an ultrasonic microphone near the roost.
