1. Studies were conducted to assess the response of a seasonal cave-dwelling bat and its insect prey to natural and experimental changes in barometric pressure. 2. The Eastern Pipistrelle, Pipistrellus subflavus, tracks barometric pressure metabolically. 3. Eastern Pipistrelles potentially use pressure as a cue for predicting the relative abundance of aerial insect prey outside the roost. 4. Barometric pressure tracking affords these bats an opportunity to conserve limited energy and make appropriate foraging decisions. 5. Barometric pressure tracking is viewed as an alternative evolutionary strategy to torpor and may be a widespread phenomenon among insect-feeding bats that roost deep within caves.
