Cover Story: Effective conservation strategies rely on knowledge of social drivers of animal behaviour. Koalas are generally solitary, and yet their social arrangement is clear. Previous research suggests that koalas can perceive the body size attributes of the males via their vocalisations (i.e., bellows). We tested the behavioural responses of 20 free-ranging koalas to bellow recordings collected from small (< 6 kg) and large (> 8.5 kg) adult male koalas. We report evidence of intra-male competition, with adult males approaching bellow playbacks, particularly those from small-sized males. In contrast, juvenile males were averse to the playbacks. No patterns in the response of females were detected. Our results provide the strongest evidence to date that bellows are primarily a means by which males occupy and control space during breeding season. View this paper
