Report a Bat Sighting – Help biologists learn about bat populations & get a free t-shirt! 

What is this data used for? Bat biologists and land managers use bat sightings as a means of learning more about bat biology and bat resource use. Bat populations are declining in regions of North America (see the Threats to Bats on CBC's website) and biologists need to learn more about bat roosting requirements if they want to conserve these populations. CBC is a novel attempt to gain that understanding because it sets the groundwork. It lets biologists know where bats are, and, for many years, that has been a struggle for biologists. If we are lucky, climbers may find large colonies of bats that biologists can study and monitor to understand how bats survive, reproduce, and hibernate in cracks.
