| Résumé : | Divorce between seasons is a common phenomenon in seabirds, whereas within-season mate change is rarely observed. We report four cases of within-season mate change in renesting Common Terns Sterna hirundo during a year of heavy predation by a Long-eared Owl Asio otus, when we found more deserted clutches, lower hatching success as well as more disappeared chicks compared to other years. Within-season nest-site fidelity also decreased under predation pressure. |
