Golden-winged Warbler

Golden-winged Warbler

The Golden-winged Warbler is one of North America's most rapidly declining songbirds. Genetic swamping, or hybridization, with the closely-related Blue-winged Warbler in areas where the species' breeding ranges overlap (such as southern Ontario) is thought to be the biggest threat to the Golden-winged Warbler. We strongly suspect that the key to recovery lies in core areas such as Manitoba and south of Ontario's southern shield, where Golden-winged Warbler populations persist.

Bird Studies Canada is addressing priority research questions to direct Golden-winged Warbler conservation. We're working to determine the full extent of the species' range; identifying additional key areas for conservation; assessing the severity of threats such as habitat fragmentation, hybridization, and cowbird parasitism; and developing a better understanding of habitat needs.

Our work in Manitoba revealed a much larger Golden-winged Warbler population there than previously estimated, and demonstrated the importance of focusing conservation efforts and dollars in the province.
