Echolocation calls of Pteronotus davyi (Chiroptera, Mormoopidae) from Panama

We studied echolocation signals broadcast by free-flying naked-backed bats (Pteronotus davyi) from Panama. Calls consisted of a segment of constant frequency, followed by a downward frequency modulated sweep, and ended with a short segment of quasi-constant frequency. Up to three harmonics were dete...

description We studied echolocation signals broadcast by free-flying naked-backed bats (Pteronotus davyi) from Panama. Calls consisted of a segment of constant frequency, followed by a downward frequency modulated sweep, and ended with a short segment of quasi-constant frequency.
