Abstract

Vocal communication is an emblematic feature of group-living animals, used to share information and strengthen social bonds. Vocalizations are also used to coordinate group-level behaviours in many taxa, but little is known of the factors that may influence vocal behaviour during cooperative acts. Allied male Indo-Pacific bottlenose dolphins (Tursiops aduncus) use the ‘pop’ vocalization as a coercive signal when working together to herd single oestrous females. Using long-term association and acoustic data, we examined the influence o
