Greater wing-coverts and remiges ochraceous orange with well-spaced fuscous bars and only a few darker mottles between bars; upper side of rectrices similar, ochraceous tawny with five exposed fuscous bars, each 5 – 8 mm wide, and with a few dusky mottles or stipples within the broader ochraceous zones. The entire extent of the underparts, including wing linings, yellow-ocher with whitish basal parts of the feathers, and small, roundish subterminal spots on most feathers of the breast and belly; tarsi with yellow-ocher feathers all the way to the base of the toes. Irides dark brown, bill pale horn, feet pinkish drab with pale grey talons.
