Some, like the red bat, stay in our area for the summer months. In comparison, silver-haired bats are only in the preserves for a day or two as a stop on their journey to more northern forests. Spring in the Preserves: Bats Bats can be found in every part of the Forest Preserves’ nearly 70,000 acres, although some like the tricolored bat are very rare. Even if you don’t see any bats on your visit, be happy they’re here. All our local bats eat insects: A single half- ounce little brown bat can eat half its body weight in insects each night.
