The northern waterthrush ( Parkesia noveboracensis ) is one of the larger New World warblers and one of the Nearctic-Neotropical migratory songbirds. It breeds in the northern part of North America in Canada and the northern United States including Alaska. This bird is migratory, wintering in Central America, the West Indies and Florida, as well as in Venezuela, Colombia, and Ecuador. It is a very rare vagrant to other South American countries and to western Europe.
