Migratory in USA, with marked post-breeding dispersal; winters along Gulf coast, in Florida, Caribbean, C America and N South America; some birds remain on Atlantic coast of USA, N to New Jersey; W birds winter in Mexico. Little known about movements of S populations of S America, but some evidence suggesting post- breeding dispersal; increasingly frequent records from Tristan da Cunha (S Atlantic) may indicate some true migration. Accidental to Canada, Alaska, Bermuda and Azores.   (del Hoyo J, Elliott A, Sargatal J (eds), 1992)
