Listen to Bat Sounds

During an inspection, we found a maternity roost in this attic. You usually cannot hear a single bat, but in colonies this size in an enclosed space, you can hear bat noises in the attic. Like most mammals, bats have vocalizations to communicate. These vocalizations typically sound like squeaking or chittering sounds. You can hear these sounds at dusk or dawn when bats are most active. (Did you know bats are one of the few mammals that sing?)
