| Abstract: | Cardioderma cor responded with head movements and flight toward speakers broadcasting calls of frogs and crickets which contained only sonic frequencies. Prey were presented such that their movements initially generated sounds, but then the prey moved onto the water layer of the glass sheet and sounds were eliminated. The bats emitted echolocation signals while hunting in this situation. The results demonstrate the importance of passive hearing for prey localization in this bat, and further suggest that when prey-generated sounds and echolocation signals offer conflicting information the bat’s behavior is guided by the former. |
