Montana tianshanica
Behaviour:
The calling song of M. tianshanica differs from that of all other Montana species. It consists of relatively short, polysyllabic (ca. 3–9 macrosyllables) echemes (syllable repetition rate ca. 25 Hz) separated from each other by intervals of about the same duration (Fig. 7I). Regularly some echemes contain microsyllables at the beginning and only few macrosyllables. [1]
