Males call sporadically. Three neighbors were studied while they called 10 m apart from one another (Haddad and Pombal Jr 1995) and advertised at intervals of 9.90+/- 1.27 sec at a temperature of 22 celcius. Calls were 2.0 sec long and had 28-35 notes per call at a rate of 14.5/s. Note duration was .04-.05 sec. Each note was a rising frequency modulated whistle with a dominant frequency range of 4.0-5.5 Khz.
