The calling song, heard both during the dy and at night, consists of disyllabic echemes repeated at the rate of about 4-15/s (depending on temperature), often grouped into short sequences of 2-4 echemes (Fig. 317, 318) but sometimes in long sequences of indefinite duration (Fig. 319, 320). Oscillographic analysis shows that opening hemisyllables are often present (though always very quiet) and that the closing hemisyllables usually last about 10-50 ms. The duration of each echeme (excluding the first opening hemisyllable, when present) is about 45-100 ms and the intervals between the echemes (within a group or during long sequences) are usually about 60-130 ms. There are no microsyllables.
