Female geladas draw the attention of males to their sexual state both by visual and vocal signals. In addition to visual cues our studies demonstrate that gelada females in oestrus use calls which are not uttered normally by anoestrous, pregnant or lactating females. A special call of the female indicates the climax of the copulation. Furthermore, individual recognition and the special meaning of these calls is indicated by playback experiments.
