Life History, Abundance, Activity, and Special Behaviors
Males call far from water in bushes and small trees. The call consists of a rarely heard initial sound – a slow coarse creaking – and a series of slow, rather low-pitched screams with a strange acoustic quality (similar to some forest Leptopelis). The elements have a duration of 0.1 sec and consist of a large number of harmonics, about 333 cps apart, with the harmonics having a complicated pattern of intensity maxima.
