The Fork-tailed Flycatcher (Tyrannus savana) breeds from southeastern Mexico south to central Argentina and Uruguay (AOU Checklist of North American Birds, 1983). The nominate race, T. s. savana, which breeds in Argentina and Chile, is highly migratory and moves north during the austral winter (ffrench, 1991). It is casual in eastern North America to southern Canada primarily along the Atlantic coast with 14 records for Florida (Robertson et aI, per. com.). All but one specimen from North America are of the migratory nominate race, T. s. savana (AOU Checklist).
