A large, sturdy olive-gray and yellow bushshrike with a distinctive black chest band that arcs up to the bill base, forming a broad necklace. In flight the dark tail has striking yellow tips. The juvenile is dull and lacks the chest band. Pairs are bold in shrubby and open country, where they forage low in bushes or grass clumps, hopping on open ground or running between clumps looking for invertebrates. The species has a varied and complex repertoire of songs and calls, the most characteristic of which is a duetted onomatopoeic “bok-mak-ie-rie,” often delivered from a conspicuous perch.
