Spectrographic description Measured calls (N=23) were 32.1-57.5 (43.7) mS in duration and in the 5.8-10 (6.6-9.0) kHz frequency range. The frequency track was double-banded (rarely single-banded) and rising and often with an upward bend in the middle and a slight downward hook at the end. Most calls showed a fine modulation, particularly in the second half of the call, with a spacing of 3.2-6.6 (5.4) mS between humps.
