The fork-tailed flycatcher (Tyrannus savana) is a passerine bird of the tyrant flycatcher family, and is the member of a genus typically referred to as kingbirds. Named for their distinguishingly long, forked tail, fork-tailed flycatchers are seen in lightly forested or grassland areas, from southern Mexico, to south past Argentina. They are most frequently observed sitting on conspicuous perches waiting for flying arthropods to fly past, they then sally out, eat their prey, and return to their perches. Northern populations near southern Mexico tend to be permanent residents, while fork-tailed flycatchers that live further south are migrants with a reputation to wander as far north as the Eastern Seaboard of the United States.
