The buff-fronted foliage-gleaner (Dendroma rufa) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is native to the Neotropical realm. 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. Their rump and uppertail coverts are a slightly paler ochraceous brown. Their wings are mostly bright rufous with darker primary coverts. Their dull rufous-brown tail has pointed feather tips. Their throat and breast are glowing ochraceous that fades to the duller ochraceous of their belly, flanks, and undertail coverts. Their iris is grayish brown to dark brown to chestnut, their maxilla blackish to dark grayish, their mandible silvery gray to olive, and their legs and feet olive to grayish green. Juveniles have a narrower forehead band than adults, with a paler crown and darker and more rufescent underparts. Subspecies D. r. chapadensis has a deeper ochraceous forehead than the nominate, and a paler gray crown with a few ochraceous spots and richer colors on the back. D. r. boliviana has a paler and more olivaceous (not gray) crown than the nominate. D. r. riveti is smaller than the nominate, with a darker crown and back, a more rufous tail, and a brownish wash on the breast and belly. D. r. columbiana has a buff forehead band that is narrower and duller than the nominate's, with an olivaceous crown, a darker back, and a much paler belly. D. r. cuchiverus is similar to columbiana but with an ochraceous forehead like the nominate's. D. r. panerythra has a paler, more grayish crown and back than cuchiverus, with deeper and more uniform ochraceous underparts.
