Convergent vocal strategies of males and females are consistent with a cooperative function of duetting in Australian magpie-larks
The relationship between the form and function of coordinated acoustic signals is poorly understood. The coordination of signals by male and female birds to produce duets could be a cooperative display or a consequence of conflict between the sexes. Australian magpie-larks (Grallina cyanoleuca) produce antiphonal duets that function primarily in cooperative territorial defence. I investigate the form of these duets to determine the individual singing strategies of males and females and relate...[Show more]
