The calling song, produced mainly in the evening and at night, consists of long sequences of disyllabic echemes repeated fairly regularly at the rate of about 2-3/s. Oscillographic analysis shows that opening hemisyllables are usually absent and that the closing hemisyllables usually last about 40-90 ms, the second of each pair often being a little longer, and sometimes louder, than the first. The duration of each echeme is about 130-180 ms and the interval between two echemes is about 140-250 ms. Microsyllables are usually absent.
