Very small endemic songbird with tiny bill and disproportionately large head. Gray above and below, with rich rufous wings, tail, and lower flanks, white throat stippled in brown, and yellow eye. The throat may appear puffy white (without stippling), depending on the bird's posture. Inhabits shrubbery, brushy areas, and bamboo stands in higher montane forests. Gives simple, high-pitched, two-note calls.
