From: Intrasexual selection drives sensitivity to pitch, formants and duration in the competitive calls of fallow bucks

Fig. 2

The responses of fallow bucks to natural groans and modified groans with lowered formant frequencies. Pairs of points joined by lines represent the response of an individual buck. Bucks responded to by looking toward the speaker faster (a) in response to lowered formant frequency groans than to natural groans. There was no consistent difference in response in the latency to move (c), or the distance moved (d) between groan types. The difference in response to the duration of looking towards the speaker (b) was not significant (see Results for statistics)
