D. Chobanov & S. Kaya , 1 male recorded . The male produced short echemes with a duration of 0.54± 0.1 s (n=12; range 0.4– 0.6 s ; Fig. 8 ). The intervals between the echemes had a duration of 3.7± 2.5 s (range 1.8– 9.5 s , n=11). An echeme contained on average 27 syllables (SRR 50.6 Hz; T =24ºC). The syllables had a mean duration of 2.5 ms and contained 1–2 impulses. The spectrum of the song had its peak between 20 and 30 kHz ( Fig. 9 ).
