Song. The song is a loud echeme-sequence lasting 10–30 s (Figs. 31–32). Each echeme consists of two parts: about 7–10 short syllables are followed by 8–14 longer ones (Figs. 33–34). Echeme repetition period averages 650 ms in our recordings from Central Asia. Quite often, male produces a succession of low-amplitude syllables at the beginning or end of the song. Duration of this additional part can vary greatly.
Comparative notes. S. scalaris is a mesophilous species living in more or less dense grass. For this reason, the mountains of Central Asia represent an isolated part of its range, similarly to G. sibiricus. Nevertheless, the songs of males from the Central Tien Shan Mts. do not differ from the songs recorded in Europe, the Caucasus, and Siberia. [1]
