Eurycorypha lesnei
Behaviour:
The call of E. lesnei consists of short, 3-syllable echemes, the first two syllables being noticeably shorter than the 3rd one, produced every 2–6 s. Mean duration of the 3rd syllable is 0.01055 s (SD=0.00312, n=9); the call does not have a distinct frequency peak but most energy is within 11.7–22.8 kHz (Figs. 56A–C). The call is very faint but audible from a distance of a few meters. [1]
