Calling song ( Fig. 7 View FIGURE 7 ). The calling song consists of echemes with an average duration of 0.33±0.06 s (0.25–0.48 s) and made up of an average 63±12 discrete syllables (48–91 syllables). On rare occasions, the echeme can be longer in duration of up to 0.72 s made up of 138 discrete syllables. Within each echeme, the average syllable duration is 0.5±0.1 ms (0.4–0.8 ms), the average down time between consecutive syllables is 4.8±0.1 ms (4.4–8.0 ms) and the average syllable period is 5.3±0.1 ms (5.2–5.5 ms). The call spectrum has a peak frequency of 29.72±0.88 kHz (28.29–31.58 kHz), and the spectral entropy is 0.68±0.03 (0.64–0.74). The frequency spectrum is broad-band and is symmetrical.
