Silver-haired bats don’t cluster in caves the way many Connecticut bats do. They roost alone or in small groups under loose bark or inside cracks in dead and dying trees, which keeps them easy to miss even where they’re genuinely present. The coastal forest fringing Hammonasset, Bluff Point, and Barn Island offers exactly that kind of scattered tree cover.
Records concentrate in September and October, more than half of the state’s 14 total sightings, a pattern that fits one of the most migratory bats in North America passing through Connecticut on its way south rather than settling in for the season. NatureServe ranks the species S3, vulnerable, in Connecticut, a step below its more secure global status.
