Bats! The only flying mammals on earth, bats are fascinating yet largely misunderstood creatures. We find them strange because of their squashed faces, their ability to feed in the dark, and their nearly-transparent wings. Come learn from the Illinois Bat Conservation Program bat experts about the latest in acoustic monitoring and mist netting.

Explore why we need bats as predators, see how they care for their young, and find out how you can do to save our dwindling native bat populations.
