A quite small flycatcher that is a fairly rare inhabitant of the canopy and borders of humid forests, where it typically perches in an upright position on exposed branches. Sometimes follows mixed-species flocks. Note the broad white eyebrow contrasting with the black crown (without yellow) and a prominent mask. Mostly olive-brown above and yellow below. Resembles Social Flycatcher, but is smaller and lacks the red crown patch and white throat. The song is a harsh “djew-djew” repeated energetically.
