The Nashville warbler (Leiothlypis ruficapilla) is a small songbird in the New World warbler family, Parulidae. It is found in North and Central America.
It breeds in parts of the northern and western United States and southern Canada, and migrates to winter in southern California and Texas, Mexico, and the north of Central America. In their breeding range, they prefer open mixed woods and bog habitats.
Nashville warblers forage by gleaning in the lower parts of trees and shrubs, frequently flicking their tails. In winter, they join together into loose flocks, and sometimes join mixed-species feeding flocks. These birds mainly eat insects, but will supplement this diet with berries and nectar in the winter.
