The breeding range extends from east-central Alaska and southern Mackenzie District east to southern Quebec and southwestern Newfoundland. In the contiguous United States it breeds from northeast California east to central Louisiana, central Tennessee, and the Atlantic Coast. The western blue-winged teal inhabits that part of the breeding range west of the Appalachian Mountains. The Atlantic blue-winged teal nests along the Atlantic Coast from New Brunswick to Pea Island, North Carolina.
