Nest reliefs in a cryptically incubating shorebird are quick, but vocal
Original language description
In species with biparental care, coordination of parental behaviour between pair members increases reproductive success. Coordination is difficult if opportunities to communicate are scarce, which might have led to the evolution of elaborate nest relief rituals in species facing a low predation risk. However, whether such conspicuous rituals also evolved in species that avoid predation by relying on crypsis remains unclear. Here, we used a continuous monitoring system to describe nest relief behaviour during incubation in an Arctic breeding shorebird with passive nest defence, the Semipalmated Sandpiper Calidris pusilla. We also explored whether behaviour of exchanging parents informs about parental coordination and predicts incubation effort. We found that incubating parents vocalized twice as much before the arrival of their partner than during other times of incubation. In at least 75 percent of exchanges, the incubating parent left the nest only after its partner had returned and initiated the ne
