    We investigated population genetic structure and gene flow patterns in a polytypic passerine, the reed warbler which shows a migratory divide in central Europe. Using 10 polymorphic microsatellite loci and extensive sampling we found low but significant overall genetic differentiation. Hierarchical F-statistics and barrier analyses showed low but significant genetic differentiation of Iberian populations, and also slight genetic differences across the migratory divide and between subspecies. Three individual-based Bayesian methods, however, inferred a single genetic unit. Our study thus found low levels of genetic differentiation among reed warbler populations but this genetic differentiation was not pronounced enough to detect a clear population structure. This result indicates high levels of gene flow and suggests a possibly recent divergence of European populations after a rapid range expansion.
