Fig. 4

The responses of fallow bucks to natural groans and modified groans with shortened durations. Pairs of points joined by lines represent the response of an individual buck. Bucks were slower to look towards the speaker (a), looked for less time (b) and were more likely to approach the speaker (b) in response to groans with shortened durations than to natural groans. There was no consistent difference in response in the latency to begin moving (c) (see Results for statistics)
