Function of Duetting in Birds Antiphonal signaling, or duetting behavior, exists across many species of birds and other animals (Dowling 2015). Duets are a form of acoustic signaling in which a pair of individuals participates in making the signal rather than the more common acoustic signal where only one animal participates in being the sender. The costs associated with producing a duet are likely higher than the costs associated with individual acoustical signals. This is because duets likely require more practice, coordination, and attentiveness by participants (Dahlin, 2012). Acoustic signaling is important for many behaviors in animals such as in mating and defense. Understanding the function of duetting will further our understanding of acoustic signaling in general, allowing us to understand more about animal adaptation and behavior.
Multiple hypotheses have been suggested to explain the function of duetting in birds. One hypothesis for duetting is the joint territory defense hypothesis which suggests that birds use duets so that the pair can defend their territory against rivals of the same species. Another hypothesis is mate-guarding in which a member of the pair duets in order to keep same-sex rivals away from their mate. A third hypothesis is the acoustic contact hypothesis. This hypothesizes that birds use duets to remain aware of their mating partners in areas where visual contact might not be feasible, for example in a habitat that is very dense (Mennill,…
