The effect of chorus organization on mate localization in the Painted Reed frog (Hyperolius marmoratus)

Summary Experiments with female Painted Reed frog (Hyperolius marmoratus) indicate that temporal separation of the calls of neighbouring males does not enhance their locatability. The ability of females to locate a sound source is not impaired when identical calls are broadcast simultaneously through two spatially separated loudspeakers (n=8). We suggest that call alternation may be important in the spatial distribution of males rather than in the ability of females to locate mates.
