The white-browed foliage-gleaner (Anabacerthia amaurotis) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is native to the Atlantic Forest. 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.
The white-browed foliage gleaner is monotypic. 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... Wikipedia →
