Adult is a powdery gray-blue overall with blue highlights on the wings and tail. The face and sides are tinged soft gray-brown. Varies considerably over range; birds in southern Southeast Asian portion of range are very gray, lacking bright colors. Sexes alike. Acrobatic, often hanging upside down on branches to probe for invertebrates and fruit hidden by foliage. Listen for its high-pitched paired whistles: “dwweeee-deeee.”

Attractive ground-dwelling bird. Slender and long-tailed, bright yellow below with paler throat and grayish-olive back; extremely variable. Tail is black with white outer feathers; often pumps tail up and down while walking on the ground. Young birds lack yellow color, but have distinctive head pattern. Often seen near water. Listen for high-pitched, piercing call note. Common breeder on Arctic tundra from Alaska to Russia; found in grassy and waterside habitats in Southeast Asian wintering grounds and in migration.

Small short-tailed antbird of understory of dense humid forest. Yellow with black streaking, belly usually a duller yellowish tan. Distinguished from Peruvian Warbling-Antbird by its brighter yellow plumage. Typically found in dense viny habitats along rivers or forest clearings; where bamboo is present, largely restricted to this habitat. Often in pairs, but only rarely joins mixed species flocks. Song almost identical to Peruvian Warbling-Antbird, but some calls differ; in areas of overlap, they are typically found in different habitats: Yellow-breasted found in bamboo and dense secondary growth, Peruvian found in tree fall gaps and along streams in more mature rainforest.
