A forest species. Although difficult to find, its characteristic voice was heard in several places. Such aural records are included in the distribution map. Known from Côte d’Ivoire and Ghana.

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.
