The highest densities of Kentucky Warblers are found in the Lower Hudson River Valley. There are scattered populations in the Coastal Lowlands and even more scattered locations in central and western New York in the Delaware, Susquehanna, and Allegheny River valleys.

Global Distribution [-]
Breeding: Kentucky Warblers are found during the breeding season from southeastern Nebraska, east across central Iowa, southwestern Wisconsin, northeastern Illinois, central Indiana, north-central Ohio, southern Pennsylvania, northern New Jersey, and southeastern New York, to southwestern Connecticut, south to Texas, the Gulf Coast to northwestern Florida, central Georgia, and South Carolina, and west to eastern Kansas and central Oklahoma (AOU 1983 cited in NatureServe 2005). Non-breeding: During the non-breeding season Kentucky Warblers are typically found in tropical zones of southern Veracruz and Oaxaca, through Chiapas, the base of the Yucatan Peninsula, primarily on the Caribbean slope of northern Central America, throughout Costa Rica and Panama, and into northern Colombia and northwestern Venezuela (AOU 1983 cited in NatureServe 2005, McDonald 1998 cited in NatureServe 2005). They are uncommon transients through the West Indies; some may overwinter on eastern and southern West Indies islands (McDonald 1998 cited in NatureServe 2005).
