Pennsylvania’s records for the northern hoary bat cluster at Presque Isle State Park on Lake Erie, Pymatuning’s reservoir-edge woods, and the forested corridor along Delaware Water Gap, the kind of tree cover this solitary, tree-roosting bat favors over caves. Nearly all of the state’s handful of sightings come from iNaturalist rather than museum specimens, unusual for a bat that’s typically heard more than seen, and no Pennsylvania record has been logged between November and March. That gap fits a species known for migrating rather than overwintering in the state.
NatureServe rates it Apparently Secure in Pennsylvania even though it’s considered globally Vulnerable, a reminder that a healthy regional foothold doesn’t guarantee the species is doing well everywhere it roosts.
