Fairly small buffy-chestnut bird with dark grayish wings. The pale buffy eyering and eyebrow and bright rusty tail stand out. Sexes similar. Occurs from Panama to western Ecuador, in the understory and middle levels of foothill forest up to around 1,200 m. Usually seen singly or in pairs, following a mixed-species flock. Like other foliage-gleaners, often hitches along branches and probes into clusters of dead leaves. In range perhaps most similar to Scaly-throated Foliage-gleaner, but Slaty-winged is brighter buffy on the face and neck and has darker wings.
