The song was emitted in isolated syllables. Each syllable started with a short “buzz”, which is visible on the oscillogram as a dense impulse sequence (~200 ms) (Fig. 3). A long break of several seconds was followed by a sequence of clicks that started off slowly (at the beginning, the single clicks could be distinguished by the naked ear) and accelerated towards the end. The rhythm of these clicks was similar to that produced by a ping-pong ball falling to the floor. The second part of the syllable is visible on the oscillogram as a sequence of impulses condensing towards the end (~2000 ms) (Fig. 3).
