A shrike-like bird of thickets in secondary forest and forest edge, often seen high above the ground. Has a bicolored appearance, being wholly white below and almost entirely iridescent black above except for a white rump, a red eye, and the female’s white lores. Similar to several bicolored shrikelike birds in the region, but note Red-eyed Puffback’s behavior as it perches laterally like a bushshrike, as well as its red eye, hoarse voice, and relatively small bill. Shy but vocal, giving sharp, well spaced “kyew! kyew! kyew!” calls, repeated “reuw, reuw, reuw” calls, and rising trilled calls preceded by quick chatters.
