Abstract:A medium sized Acrocephalus Warbler which initially could not be identified was captured in Bavaria in June 1995. The bird held a territory between two Great Reed Warbler males and responded to playback of Great Reed Warbler song. Using PCR with microsatellite primers sequence the bird could be identified as a Great Reed x Reed Warbler hybrid (Fig. 1). Based on mt DNA sequence analysis the hybrid's mother was a Great Reed Warbler (Fig. 2). With respect to the hybridization process the main difference between the parental species occur in body size (Great Reed Warbler being 2.7 times larger than Reed Warbler) and mating systems. Whether the hybrid resulted from an extra-pair copulation or a mixed pairing is unknown. External morphology of the hybrid was intermediate between the parental species (Tab). The bird sang a mixed song incorporating both parent species' songs (predominantly Great Reed Warbler) as well as intermediate songs into its own (Fig. 3).
