Silver-haired bats carry a NatureServe S2 imperiled rank in West Virginia despite a healthier G4 global rating, reflecting how thin the state’s documentation is for one of North America’s most migratory bats: just 17 records total, most of them (14) from iNaturalist rather than specimen surveys. This species roosts alone under bark or in tree cavities rather than in caves or buildings, which likely contributes to how sparsely it’s picked up compared to more colonial bats.
Records scatter across eight separate months with two modest bumps, February and June (4 each), too thin and spread out to describe a confident migratory pattern, though the October uptick hints at the fall passage documented more strongly for this species elsewhere along the Appalachians.
