One of our tree bat species. Not typically found in Maryland in summer. Usually migrates south for winter, but some may linger late into the season, entering torpor during cold weather. According to Maryland DNR, overwintering Silver-haired Bats may spend the winter "under loose bark, in rock crevices, in clumps of leaves, in woodpecker holes, in bird nests, sometimes open sheds, garages or outbuildings."
Calls are very similar to Big Brown Bat and should be reviewed by an expert to verify ID.
Insectivorous.
There are 15 records in the project database.
