Eastern red bats don’t roost in caves or buildings like most Connecticut bats. They hang alone in leaf clusters at the edge of tree canopy, wrapped in a furred tail membrane that makes them look like a dead leaf to a passing predator, which is why records near Hammonasset, Bluff Point, and Barn Island likely trace daytime roosts in coastal forest foliage rather than any built structure.
Records carry three bumps, May, July, and August, rather than one clean peak, tracking spring arrival and summer roosting before this species migrates south for winter instead of hibernating locally. NatureServe ranks the species S3, vulnerable, in Connecticut, notably more precarious than several of the state’s other bats, in part because it migrates instead of overwintering in protected hibernacula.
