Males of T. commodus produce a complex calling song that contains two types of chirps, as described previously (Leroy, 1966; Hill, Loftus-Hills & Gartside, 1972). For the purposes of the present study, the call of T. commodus at 23 °C is assumed to consist of one complex chirp of five high-amplitude pulses with a repetition frequency of 15 Hz, and 12 smaller pulses at 25 Hz followed by a simple chirp of 12 small pulses, also at 25 Hz. This sequence of two chirps is repeated for the duration of the call at a rate of 30min-1. The carrier frequency of the call is 3-8 kHz at 23°C (Hill, 1974).
