Common and noisy leader of mixed-species flocks in rainforest understory; almost never seen away from flocks. Note hunched posture and tendency to partially flare tail when perched. Adult male’s plumage entirely gray; female rich buff and rufous. Perches conspicuously in lower-to-middle strata, darting out to catch insects flushed by other members of the flock. Dusky-throated Antshrike behaves similarly and is often in the same flocks. Male Cinereous lacks black throat, and female Cinereous is more richly colored than Dusky-throated Antshrike. Calls of the two species are very different.
