The male calling song was presented by Ragge (1986) and is shown in g. 10 (two echemes). The calling song of a male is an echeme last- ing for about 1.0-1.5/s and constisting of about 20-22 syllables repeated at a rate of about 18-20/s ( g. 11). Each echeme begins quietly, rapidly increasing in intensity. The öscillographic analysis shows that the down- stroke hemisyllables have a characteristic pattern of gaps, which often become obscured towards the end of the echeme. The echemes are often produced singly and repeated at irregular intervals, as Ragge & Reynolds (1998) reported.
