Isolation and characterization of polymorphic microsatellites isolated from the Spotless starling (Sturnus unicolor) and cross-species amplification in the European starling (Sturnus vulgaris)

Spotless and European starlings (Sturnus unicolor and Sturnus vulgaris) have attracted attention from researchers interested in sexual selection, evolution of parental care and reproductive strategies. Both species show high levels of intraspecific nest parasitism and extra-pair paternity, but research in this area is hampered by a lack of molecular markers specific for these species. Here, we describe a set of primers for nine microsatellite loci in spotless starlings, eight of which are highly polymorphic (7.37 alleles in average). These microsatellites are also polymorphic in European starlings (6.75 alleles in average).
