description
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 3 B). 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 3 C). 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 3 C). 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 3 D). 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 3 E). 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.
distribution
Distribution. P. zigana is endemic to Anatolia. It was recorded only from Giresun and Trabzon provinces of Turkey (Figure 3 A) (Ünal 2013). Song recording. Male specimens collected from Turkey, Giresun, Tamdere, 40 ° 30.24 ’ N, 038 ° 21.09 ’ E, 1692 m, 17. VIII. 2015 (by D. Şirin, M. S. Taylan & A. Mol) and calling song recorded from two males at 31 ° C in the field and 25 – 26 ° C in the laboratory (by D. Şirin & M. S. Taylan).
