Bioacoustics of Squamiana kurmana

Description of song . Four records from two males were examined. The calling song consists of a series of regular phrases ( Figure 18B ) with an interval of 2.17– 4.58 s (3.28 ± 0.52). Phrase durations vary between 3.35– 6.20 s (4.94 ± 1.26) and phrases consist of 23–43 (33.12 ± 5.25) syllables. The phrase begins with 1–3 low amplitude syllables (first one is the lowest) and reaches maximum intensity ( Figure 18C ). Syllables duration varies between 89 and 98 ms (91.76 ± 2.65) with an interval of 42–59 ms (51.14 ± 2.17). Oscillographic analyses show that each syllable contains two parts. First part of the syllable is relatively shorter and quieter than the second part of the syllable (except the first 1–2 syllables in the phrase) ( Figure 18D ). First part of the syllable lasts for 31–39 ms (34.24 ± 1.56) and is followed by a second part after an interval of 1–5 ms (3.42 ± 0.82). The second part of the syllable is much louder (except for the 1–2 syllables of the beginning) and is longer than the first part; its duration varies between 49–57 ms (52.48 ± 2.62).
