Formerly treated as part of the Sibilant Sirystes complex, this species was split based on vocal and range differences. Its bright white rump is striking in flight and helps distinguish it from similar tyrant flycatchers. It often sings clear, sibilant whistles from high exposed perches at dawn and dusk.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats with quick sallies from high perches
Social Behavior
Usually seen singly or in pairs, maintaining territories within suitable forest patches. Nests are likely open cups placed high in trees on horizontal branches. Pairs vocalize frequently at dawn to advertise territory.

A series of clear, sibilant whistled notes, often rising and slightly drawn out, delivered from exposed canopy perches. Calls include sharp, penetrating whistles given repeatedly at dawn and dusk.
