The complete county distribution, spread across 11 Oregon counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Pallid bats hunt in a way almost no other Oregon bat does: they drop to the ground to grab scorpions, crickets, and other large ground-dwelling prey, using huge ears to pick up the faint rustle of movement rather than echolocation alone. Records near the Deschutes and Willamette National Forests trace the drier, open terrain this species favors over dense, wet forest.

Records cluster from June through August, led by August, tracking peak summer foraging and maternity-roost activity. NatureServe ranks the species S2, imperiled, in Oregon, notably more precarious here than its secure global status, and the record leans heavily on GBIF specimen data over photographs, a fair reflection of a bat that’s active well after dark.
