Eastern red bats are genuinely scarce in New Hampshire’s record, just 10 sightings total, and NatureServe’s S3B breeding rank, vulnerable, sits below the species’ G3 global rank, itself already a globally vulnerable status tied to wind-turbine mortality and white-nose syndrome pressure on the broader bat community. This species roosts alone in foliage rather than in caves, which makes it harder to detect than colonial cave bats and likely helps explain the thin record here.
Nearly half the sightings, 4 of 10, land in September, consistent with the state’s other migratory bats passing through on their way south for the winter; the remaining records are scattered singly from May through November with no other clear pattern in a dataset this small.
