Fig. 1

The responses of fallow bucks to natural groans and modified groans with lowered f o . Pairs of points joined by lines represent the response of an individual buck. Bucks responded to by looking toward the speaker faster (a) and for longer (b) in response to f o lowered groans than to natural groans. There was no consistent difference in response in either the latency to move (c), or the distance moved (d) between groan types (see Results for statistics)
