The calling song of male G. integer consists of chirps with two or three sound pulses each (carrier frequency of approximately 4.2 kHz). Males call in trains of chirps, defined as bouts, comprising a period of calling with no pause greater than 100 ms (Fig. 1A) (Hedrick, 1988). A male’s calling bout length is heri- table, and females preferentially approach sources of calls with long bouts versus those with short bouts (Hedrick, 1986, 1988). By contrast to calling song, courtship song in G. integer consists of 4.2 kHz sound pulses interspersed with higher amplitude, higher frequency (13 kHz) single sound pulses (Fig. 1B).
