Description of song . Four records from two males were examined. The calling song has a complex signal structure and its durations vary between 21.87– 28.24 s (24.65 ± 2.12). Oscillographic analyses show that the male calling consists of three different sections (I, II and III) ( Figure 3B ). The Section I has a crescendo structure and its duration varies between 13.15– 19.45 s (16.14 ± 1.58) and consists of 16–17 syllable series, which include two different syllable groups ( Figure 3C ). First syllable group duration varies between 158–189 ms (172 ± 6.12) and includes approximately 7 syllables (first syllable is the loudest one and its duration varies between 27–34 ms (31± 1.75), whereas the other syllables duration varies between 19–22 ms (21.08 ± 0.15)). The second syllable group duration varies between 716–908 ms (826 ± 12.12) and includes 16–18 syllables, and the syllable period duration varies between 39–51 ms (46.25 ± 1.77) ( Figure 3C ). The Section II consists of a series of regular syllables and its duration varies between 3.3– 3.8 s (3.46 ± 0.08). This section includes 79–84 (82.15 ± 0.68) syllables without intervals. The syllables period duration varies between 29–42 ms (36.38 ± 2.18). Each syllable includes two elements (quieter and louder) ( Figure 3D ). First element of a syllable is a quieter part and its duration varies between 4 and 9 ms (5.77 ± 1.19). The first element of syllable is followed by a louder part with an interval of 24–36 ms (28.47 ± 1.98). The Section III involves isolated regular syllables with an interval 453–756 ms (576 ± 21.02). This section includes 8–10 (9.05 ± 0.26) syllables and syllable period duration varies between 55–76 ms (62.28 ± 2.26) ( Figure 3E ). The syllables include two elements. First element of a syllable is a louder part and its duration varies between 30–40 ms (33 ms ± 1.89). The second element of a syllable is a quieter part and its duration varies between 22–29 ms (24 ms ± 1.27) and approximately includes two distinct pulses.
