Abstract

Dispersers should express different foraging or social behaviors than nondispersers to thrive in unfamiliar habitats. In pied flycatchers (Ficedula hypoleuca), “naive” dispersers (immigrants) had a more generalist diet and higher feeding rates compared with philopatric birds, but we found no difference in level of aggression. Males with more generalist diet fledged more young. This suggests that learning or early imprinting affects individual food and settlement choices and that dispersers adopt different life-history strategies.
