Its breeds in Canada from Nova Scotia to the Northwest Territories, and in the United States in northern New England and the Upper Midwest. It winters in the West Indies. In Minnesota it breeds in Arrowhead region. It is an uncommon migrant in most of the state in May and from early August through October. It is rare in the west.

The Minnesota Ornithologists’ Union All Seasons Species Occurrence Map

In 2011 all of the wood warblers were reclassified resulting in new genus names for almost all of them. The genus Dendroica, with 29 members, was merged with the genus Setophaga, with just 3 members. All of the former Dendroica species have been renamed to Setophaga.

Cape May Warbler, formerly Dendroica tigrina, is now Setophaga tigrina.
