Audiogram of three Common vampire bats (Desmodus rotundus). Note the close agreement between the individual bats. The arrow originating at 80 dB at 250 Hz indicates that no response could be elicited at that frequency at 80 dB from any of the bats. The gray bars indicate the dominant harmonics in their echolocation call (Greenhall, Joermann, and Schmidt, 1983).
