Medium-sized, fairly long-tailed antshrike of lowland rainforest. Perches upright in the under and midstory of mature rainforest, bamboo, and occasionally forest edges. The male is slaty gray overall while the more distinctive female has a red-orange belly. Often joins mixed-species flocks, where it typically forages slightly higher in vegetation than the similar Dusky-throated Antshrike. Males are best separated from other plain gray antshrikes by more upright posture, slightly longer tail, cleaner gray throat, and voice. Listen for a short series of rising whistles that accelerate into a trill.
