Identificación

The white-browed foliage-gleaner is 15 to 16 cm (5.9 to 6.3 in) long. It is a medium-sized furnariid with a wedge-shaped bill. The sexes have the same plumage. Adults have a wide buff-white supercilium, a dark brown band behind the eye, and an indistinct brown "moustache" on an otherwise lightly flecked and streaked, light buff, face. Their crown is brown with black-edged white feathers at the center of the back, and they have a narrow pale buff collar that extends onto the side of their neck. Their back is rich medium brown, their rump a slightly paler brown, and their uppertail coverts rufous. Their tail is rufous with bare shafts at the very end of the feathers. Their wings are rich medium brown with darker brown primary coverts. Their throat is creamy whitish, their breast light brown with wide but blurry pale buff streaks, their belly unstreaked light brown, and their flanks and undertail coverts slightly darker brown with a rufescent tinge. Their iris is dark brown, their bill pale horn with some pale gray, and their legs and feet brownish cream to cream-tinged olive.

Taxonomía

The white-browed foliage-gleaner was previously included in genus Philydor but a 2011 paper made it plain that it did not belong there. The same paper found the ochre-breasted foliage-gleaner (A. lichtensteini) and the white-browed to be sister species.<p>The white-browed foliage gleaner is monotypic.

Comportamiento

The white-browed foliage-gleaner is a year-round resident throughout its range.<p>The white-browed foliage-gleaner feeds on adult and larval arthropods. It usually forages as part of mixed-species feeding flocks, and usually in the forest's understory though it will feed as high as the subcanopy. It acrobatically gleans, probes, and pecks for its prey in dead leaves, debris, and branches. It occasionally will sally a short distance from a perch to capture prey.<p>Nothing is known about the white-browed foliage-gleaner's breeding biology.<p>The white-browed foliage-gleaner's song is "a short, accelerated, ascending and descending series of very/ext. high 'seep' notes". Its call is an "extr. high, thin 'steep tseep seepseep -' ".
