Mid-sized bushshrike that is completely black with pale blue-gray eyes. Found in the undergrowth of humid forest at moderate elevations. A skilled skulker that is most often detected by voice. The most distinctive vocalization is a series of four bell-like whistles; also gives low scolding notes. Very similar to Albertine Boubou, but prefers lower-elevation forest and has a pale eye.
