In the calling song, two types of verses are observed, short and long ones. The short verses start with a few (2–3) long syllables, called macrosyllables, which contain a series of impulses, and are followed by a short series of microsyllables (for details see Heller 1988). The long verses consist of a sequence of three-syllabic echemes. The first two syllables of each echeme are shorter and softer than the last one. Typically, a long verse follows immediately after a short one ( Fig. 8 C).
