The call of E. iaculator is a continuous train of short but distinctly separate syllables, with syl- lables produced at the rate of only 2/sec (at 26°C); mean syllable duration is 0.04264 (SD=0.13340, n=790), with the frequency peak at 11.7–14.6 kHz (Figs. 49I–L); each syllable consists on average of 11 impulses (SD=2.101, n=104). The call is loud and readily audible to the human ear from several meters.
Males usually start calling shortly after sunset from dense bushes, often very low to the ground (from a few centimeters to about 3 meters above the ground.) While calling, the male invariably hangs upside down on a thin branch and is relatively oblivious to disturbance. Calling males appear to be territorial and are spaced regularly by at least 10 m; the same tree or bush never has more than one calling male.
The population in the northeastern part of the Cheringoma Plateau is unusual in that the males often sing throughout the day, including noontime. This population, however, shows no statistically significant differences from the populations elsewhere in the Gorongosa region in either the parameters of the call or their morphological characters.
