Reporting your
bat observations

You can help by acting as our eyes and ears by sharing your observations of bats and your knowledge of bat roost site locations with Colorado Bat Watch.  

Help us find out where bats are roosting

Bat roost sites are where bats live. Roost sites are critically important in the daily lives of bats. They provide shelter and protection from predators when bats are not active. In spring and summer, a roost offers a safe place for female bats to give birth and rear young. If disturbed at this sensitive time, female bats may abandon the roost and their young. To survive winter, hibernating bat species need roost sites with stable temperatures and high humidity, such as caves, mines, and rock crevices. Monitoring and protecting bats at roost sites can help conserve bat populations. 

We are particularly interested in observations of bats roosting in trees, talus, bat houses, barns, attics, outbuildings, bridges, and other structures. If a bat is not flying, then it is roosting. If you see a bat flying, it might mean a roost is nearby.
