Debrona cervina

Behaviour: 

The stationary call of D. cervina is acoustically identical to the one produced while flying and consists of a long, uninterrupted series of syllables produced every 0.9–2.0 s; mean syllable duration is 0.26 s (SD=0.0342, n=25); the peak frequency of the call is 5.9–6.4 kHz, with a strong harmonic at 11.7–12.3 kHz (Figs. 54D–F). The call is very loud and audible from a distance of at least 100 m. [1]
