Avian duets are formed when two birds coordinate their songs. Most research on the evolution and function of duetting has focused on species with highly coordinated duets, and less is known about the

The duets of birds have intrigued biologists for a long time, yet much remains unknown about the evolution of these striking collective displays. This is because previous studies on duet evolution hav
