Identifying patterns of individual movements in spatial and temporal scales can provide valuableinsight into the structure of populations and the dynamics of communities and ecosystems. Especiallyfor migrating birds, that can face a variety of unfavorable conditions along their journey, resolvingmovements of individuals across their annual cycle is necessary in order to design better targetedconservation strategies. Here, we studied the movements of a small migratory falcon, the LesserKestrel (Falco naumanni), by genetically assigning feathers from individuals of unknown origin thatconcentrate in large roosts during the pre-migratory period. Our indings suggest that birds frommultiple breeding populations in the Central and Eastern Mediterranean region move towards two premigratorysites in theBalkans, some of them detouring greatly from their expected flyways, travelling more than500kmtoreachthesesitesandprepareforthepost-nuptialmigration.Byidentifyingtheoriginofindividualsusingthepre-migratorysites,notonlyweprovideabetterunderstandingofthepossibleimpactof localthreatsat these sites on multiple breedingpopulationsbutalsoinform thedesignofefectiveconservationactionsforthespecies.
