Rather large headed and overall greenish flycatcher of humid tropical and subtropical forest; infrequently encountered. Inconspicuous, usually perching rather upright and quietly at mid-levels in the forest interior, rarely at edges; does not flick its wings or tail. Plumage relatively distinctive, with a contrasting, complete whitish eyering set in a pale grayish face. Lacks any distinct pale wingbars. Call is a high, shrill, insect-like note that does not draw attention.
