Audio 1 (AUDIO)

Smithsonian Tropical Research Institute

Caption

Courtship song of Centurio senex slowed down 10 times and therefore transformed from ultrasound into the range audible to humans. There are short echolocation calls, interrupted by several trill sequences, audible wing beats and finally a very loud scream. This last scream is the same call that is heard at the end of Video 1 without downward transformation.
