Relatively short distance migrant, which arrives on breeding grounds early, mid-Mar, and departs by mid-Aug. Mostly moves across interior W half of USA, and also fairly common to uncommon across inland Mexico. Most non-breeders spend all year in wintering range. Rarely winters S to N South America.   (del Hoyo J, Elliott A, Sargatal J (eds), 1996)
