Distribution

According to reviews [7,43,63], Swainson's warbler breeds in the southeastern United States and winters on Caribbean Islands and portions of the Yucatan Peninsula. Swainson's warbler's breeding range extends along the Gulf Coast from northwestern Florida to eastern Texas, north through eastern Oklahoma, and east through southern Missouri, southern Illinois, and parts of Tennessee, Kentucky, Virginia, and West Virginia to the coast of North Carolina. Although rare, Swainson's warbler also breeds in Maryland and Delaware. Swainson's warblers migrate through southern Florida or along the Gulf Coast to wintering grounds on the Yucatan Peninsula including northern Guatemala, Belize, and the Mexican states of Quintana Roo and Campeche. Swainson's warblers also overwinter in Cuba, Jamaica, the Bahamas and other Caribbean islands [7,43,63]. A map of Swainson's warbler's range can be found at NatureServe.

The following lists are speculative and are based on Swainson's warbler's distribution information and the habitat characteristics and species composition of communities Swainson's warblers are known to occupy during migration and breeding. There is not conclusive evidence that Swainson's warblers occur in all the habitat types listed, and some community types may have been omitted. Swainson's warblers are observed rarely in some of the communities listed and more often in others. See the Preferred Habitat section for more detail.
