: The experiment involved the playback of an individual who was present in the group for the entire duration of the experiment. To avoid any potential effects of the playbacks on the caller individual, we kept our sample size to a minimum. We did not observe any significant changes in the caller individual's behaviour during and after the experiment. The experiment and observational data collection protocols were approved by Ezemvelo KZN Wildlife, South Africa and the Ethics Commission of the University of Neuchâtel (permit number 28/2018).
