B. Çıplak , S. Kaya & D. Cho-banov, 2 males recorded . The males produced short echemes with a duration of 0.72± 0.1 s (n=24; range 0.6– 1.0 s ; Fig. 8 ). The intervals between the echemes had a duration of 2.5± 3.6 s (range 0.8– 14.6 s , n=11). An echeme contained on average 36 syllables (SRR 50.4 Hz; T =23ºC). The syllables had a mean duration of 4.8 ms and contained 2 impulses.
