Fairly common, but easily overlooked, medium-sized woodcreeper of humid tropical forest; infrequently seen away from ant swarms. Found singly or in small groups, often with Ruddy and Northern Barred Woodcreepers at army ant swarms. Mainly perches upright on slender trunks fairly low to the ground, less often at middle levels; often rather sluggish. Combination of face pattern, contrasting rusty wings, and behavior is distinctive. Usually rather quiet; at times gives plaintive mew calls and a prolonged chipping rattled song.
