识别特征
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.
分类信息
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.

Sumatran Wren-Babbler
Napothera albostriata
With its long curved bill, this uncommon Sumatran mountain forest endemic is unique within its limited range. Forages alone or in pairs, often in dense undergrowth where it can be difficult to see; listen for its song, a well-spaced series of even, clipped whistles that sound like they should be coming from a small owl. If lucky enough to catch a glimpse, look for a streaky dark brown body, very short tail, and bright white throat.
Madagascar Pratincole
Glareola ocularis
Dark, long-winged, elegant bird that is halfway between a tern and a shorebird in shape. Nests along rocky rivers and coastlines, and sometimes sits in open fields. Spends much of its time feeding on aerial insects on the wing, and can be seen flying almost anywhere, often in small flocks. Pratincoles have a distinctive shape, and Madagascar Pratincole is darker than all other pratincoles within its range.
Swamp Greenbul
Thescelocichla leucopleura
A loud, boisterous greenbul that is dark gray-green above and pale below. The back, head, and cheeks are all brownish, but feathers on the head have white centers that give them a distinctly grizzled appearance. The underparts grow plainer and whiter toward the tail, which is long and brown with bright white outer feather tips. Most often found near wet, swampy forest, particularly in areas with Raphia palms. Swamp Greenbul flocks are often located by their cacophonous calls, which consist of a series of notes and cackles that are reminiscent of a recorded human conversation being played too quickly.
