- (Uploaded by Plazi for the Bat Literature Project) Bats commonly use subterranean environments for hibernation; however, few studies have investigated bat use of rocky outcrops for overwintering. We searched rocky outcrops from 15 December to 15 March, 2018–2021, and found 333 bats in 179 winter roosts. Eptesicus fuscus (Big Brown Bat) was found most often, but Lasionycteris noctivagans (Silver-haired Bat), Perimyotis subflavus (Tricolored bat), Myotis lucifugus (Little Brown Myotis), and Myotis leibii (Eastern Small-footed Myotis) were also observed. Average winter temperatures of 8 roosts were similar to temperatures in randomly sampled rock features. Pseudogymnoascus destructans was not detected on any bats. Winter roosts of Eptesicus fuscus were higher above the ground, in areas with greater forest cover, and at lower elevations than random features. Bat use of rocky outcrops as hibernacula appears widespread, and we recommend further research into use of these habitats.
