Despite an extensive literature on the role of acoustic cues in mate choice little is known about the specific vocal traits that female mammals prefer. We used resynthesis techniques and playback experiments to examine the behavioural responses of oestrous female koalas, Phascolarctos cinereus, to male bellows in which a specific acoustic cue to body size, the formants, were modified to simulate callers of different body size. Oestrous females looked longer towards, and spent more time in close… Expand
