An active small flycatcher of open woodlands and scrub. It is most similar to Eastern Wood-Pewee and migrant flycatchers of the genus Empidonax; best distinguished from these species by the bold white crescent behind the eye. Often flicks tail upwards once after landing. Its song is “Tswee-ooooooo,” with the first part explosive and the second a lazy descending whistle. On the Bahamas, the song often has two or three quick notes added afterwards. Call is a sharp “peep-peep-peep.”
