We describe 12 microsatellite loci from the Golden-winged Warbler (Vermivora chrysoptera), a bird species of conservation concern owing to competition and hybridization with the Blue-winged Warbler V. pinus). Directional mitochondral DNA introgression from V. pinus into V. chrysoptera has been reported within the hybrid zone. Frequent hybrid phenotypes suggest that nuclear introgression is also prevalent, although this has not been demonstrated conclusively with molecular markers. These microsatellites will foster explorations of the genetic interactions between these avian congeners, and amplification tests suggest that they have high cross-species utility for closely allied bird genera and families.
