Calling song

A series of short echemmes that repeat continuously, spaced by 0.24 ± 0.02 (0.221 –0.271) seconds. Each echeme lasts 0.173 ± 0.008 (0.15–0.18) seconds. The frequencies are distributed in a broad-range frequency, with F1 at 6.98 ± 0.16 (6.7–7.1), F2 at 9.32 ± 0.1 (9.2–9.5), and F3 at 9.8 ± 0.12 (9.7–10) kHz. Throughout the emission, F2 exhibits frequency modulation.

Stress call

Not recorded.
