Buff-fronted Foliage-gleaner

The buff-fronted foliage-gleaner is 18 to 19 cm (7.1 to 7.5 in) long and weighs 25 to 36 g (0.88 to 1.3 oz). It is a largish furnariid. The sexes have the same plumage. Adults of the nominate subspecies D. r. rufa have an ochraceous forehead ("front") that continues into a wide supercilium, a dark brownish gray line behind the eye, dark brownish gray lores, and ochraceous ear coverts and malars. Their crown behind the forehead is dull brownish gray with almost invisible paler streaks. Their upper back is dull brownish gray becoming ochraceous brown on the lower back. Voice: The buff-fronted foliage gleaner's song appears to be similar in most areas of South America. There it is described as "a fast, accelerating series of staccato, metallic notes, 'whi-ki-ki-ki-ke-ke-ke-kuh-kuh', sometimes descending slightly at end". In Costa Rica it is described as a "squeaky 'woika-woika-woika...' ".
