References to song. Ragge & Reynolds (1998): recordings from Western Europe; Savitsky & Lekarev (2007): recordings from the Lower Volga Region and Western Kazakhstan (Janybek, ca. 5 km from the Russia border); Savitsky (2009): recordings from Western Kazakhstan (Janybek, ca. 5 km from the Russia border).
Song. The calling song is a single echeme lasting 5–7 s and consisting of about 60–70 syllables following each other with a period of 85–100 ms in our recordings (Figs. 7–8). Each echeme begins quietly and rapidly reaches maximum intensity. There are 4–5 gaps in last two thirds or one half of a syllable (Fig. 9).
Comparative notes. The calling songs of males from the Central Tien Shan Mts. are quite similar to the songs recorded from Europe and Western Kazakhstan. [1]
