The calling song is an echeme-sequence composed of complex echemes (n = 2), and has a duration of 8.28–
), and the average interval between consecutive echemes is 20.8±2.4 ms (16.0–23.7 ms). At the start of each echeme, the first syllable is particularly long, having a duration of 12.8±2.5 ms (8.4–18.3 ms), and has the highest amplitude. The average interval between the first and second syllables is 9.0±3.8 ms (4.9–16.5 ms). The remaining part of the echeme consists of 16±3 (13–21) syllables and has an average duration of 0.16±
). These syllables show up as possibly rapid-decay pulses. The average syllable duration is distinctly shorter than the first syllable, i.e., 5.5±1.0 ms (3.4–7.1 ms), and the average interval between these consecutive syllables is 5.4±1.5 ms (2.3–7.5 ms). The call spectrum is broad-band, and has a peak frequency of 17.2±1.1 kHz (15.8–20.8 kHz).
