This large wren breeds in lowlands and foothills from sea level up to 800 m altitude in forest or open woodland, scrub, second growth and savanna. It mainly occurs on the Pacific side of the central mountain ranges. It has various amounts of rufous and black on the head and nape, a conspicuous black stripe through the red eye contrasting with white above and below, and a patterned back and white tail and wings. The rufous-backed wren forages actively in low vegetation for insects and other invertebrates.
