Abstract
Theoretical models indicate that the evolution of biparental care depends on how parents behaviorally negotiate their level of care in response to those of their partner and whether sexes and individuals consistently vary in their response (compensatory response). While compensatory response has been widely investigated empirically, its repeatability has rarely been assessed. In this study, we used a reaction norm approach to investigate the repeatability of the compensatory offspring provisioning of a parent after temporary removal of its partner in the pied flycatcher (Ficedula hypoleuca) across different breeding seasons and partners. We found that only females partially compensated for the short-term removal of the partner and their response was significantly repeatable across years while breeding with different partners. This study highlights the importance of considering among individual differences in negotiation rules to better understand the role of negotiation mechanisms in the evolution of parental care strategies.
