The song of this species (0.25 s to 0.64 s total time) is composed by a series of four to six high pitched (6.3 to 7.8 kHz) and short (0.03 to 0.05 s) notes (n=23). The fight call is a series of very short notes emitted between 2 to 8 kHz during 0.23 s to 0.32 s (n=34). The drum, a sequence of pulses, is emitted during 3.5 to 7.2 s (n=42); the four sequences in the begining are composed by four pulses and the rest by three pulses.
