Behaviour

References to song. Ragge & Reynolds (1998): recordings from Western Europe; Vedenina & Bukhvalova (2001): recordings from several localities in the Ukraine, Rostov Oblast, Volgograd Oblast, and the South Urals; 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. Male calling song consists of short echemes lasting 500–850 ms. Usually male produce from 2–3 to 10– 12 echemes with a period of 2–3 s (Fig. 86). Inner structure of an echeme is indistinct, there are several gaps only at its beginning (Figs. 87–90). Comparative notes. Our recordings of the calling song are similar to these from Europe and the South Urals. Ragge & Reynolds (1998) believe that distribution of this species in Central Asia needs to be confirmed by song studies. Our data indicate that this species actually occurs in this region.
