Abstract: Lay Summary Bird parents that share incubation coordinate their shifts to never leave the eggs alone for too long. In the wild zebra finch, parents produce vocal duets each time they meet at the nest. We measured the acoustic structure of these duets and showed that birds call differently before leaving or staying in the nest. Thus, bird parents may communicate to organize parental care.
