A recent study conducted by researchers at Lund University has shown that the calls of tawny owls influence the feeding behavior of young European robins during their southward migration. When exposed to the calls of tawny owls, the robins exhibited increased caution, resulting in reduced night-time activity and lower food intake. This adaptation, while aimed at avoiding predation, compromises their ability to build fat reserves necessary for the journey. The study highlights a clear trade-off between foraging for energy and avoiding predation. The findings suggest that longer stopovers due to decreased feeding can lead to late arrivals at wintering grounds, where competition for resources is fierce. Understanding these dynamics can help in planning protective environments for migratory birds, enhancing their chances of survival during migration.
