Short loud raspy chirps produced irregularly with long gaps of silence during afternoon, evening and (rarely) night hours. During some automatic song registrations over the whole night no activity registered. Chirps consisting of 14±4 (range 9–24; n=37) echemes (echeme repetition rate 3.95 Hz; 2.2–5.2 Hz) each containing 7±1 (6–10) syllables produced at a rate of 45.5 Hz (33.3–55.6 Hz; Fig. 10; T = 20–24oC). Syllables with opening and closing hemisyllables, the latter (assumed closing hemisyllable) much stronger than the former. The spectrum of the song broad-banded with a maximum at about 9.8±1.6 kHz (n=2–3 per specimen; Fig. 11).
