New England bats are the only true flying mammals, using precision echolocation to hunt insects in total darkness. Species such as the little brown bat, big brown bat, and red bat play a critical ecological role, consuming hundreds to thousands of insects per night. Active from April through October, most hibernate locally through winter, while some migrate.
During maternity season, mid-May through mid-August, colonies raise young in warm roosts, often in attics or barns. White-nose Syndrome has caused severe regional declines, making proper timing and professional exclusion essential when conflicts occur. Understanding seasonal biology is key to protecting both structures and bat populations
