Birds appeared to migrate in the same mean direction in spring and autumn through the Italian and Balkan Peninsulas. During spring, movements took place on a broad front from March until mid- May with a peak in mid-April; in autumn, birds migrated through Greece on a narrower front from early August to early October, with most of individuals passing through Greece in mid-September. Finally, philopatry rates were higher for adults, while juvenile birds dispersed more often and at longer distances, up to 974 km away. Our results on migration patterns generally agree with those in other studies, but we found some evidence of long-distance premigratory movements towards mainland Greece that could also shape the narrower front migration in autumn. In addition, long distance dispersal movements of juveniles in southeastern Europe, where Lesser Kestrel populations show a fragmented distribution, could facilitate gene flow between populations, thus avoiding the negative effects of mating with genetically similar individuals.</p></abstract>
