It ranges from eastern Colombia to northern Bolivia and the southwestern Brazilian Amazon. In moist lowland forest it forages mainly in the canopy and sometimes joins mixed-species flocks.
It is about 16 cm long. The grey head has a black mask bordered below by white and black malar stripes. The upperparts are olive, the underparts grey, the undertail yellow, and the base of the lower mandible pale.
It lives in moist lowland forest at about 200–1,000 m, usually below 750 m, and is mainly seen in the canopy. It also visits forest edges and sometimes forages in mixed flocks. Insects are reported, but detailed diet information is limited.
