Introduction

The Chestnut-winged Foliage-gleaner is arguably the most distinctively plumaged of the Amazonian Philydor species, especially due to its bright rufous wings and tail contrasting strongly with the grayish-brown back and crown, with a well-marked buffy loral region and throat, and a dull brownish breast, becoming paler posteriorly. This foliage-gleaner is principally distributed across southern Amazonia, although its range extends north to southeast Colombia, and there is also an apparently isolated population in southern Venezuela. Throughout, it inhabits lowland evergreen forest, especially on terra firme, although the species appears to range more consistently into seasonally flooded areas in the north of its range. Behavior seems typical of the genus as a whole, with the Chestnut-winged Foliage-gleaner being usually encountered in pairs within mixed-species foraging flocks.

Field Identification

17–19 cm; 28–36 g. Slightly larger-billed than congeners and with more contrast between wings and back. Has indistinct tawny supercilium from near bill base, where almost orange-buff, to behind eye, becoming narrower and duller posteriorly; broad but indistinct eye-ring buffy, postocular area dark grey; auriculars dull brownish, bordered below by indistinct darker streak that extends forwards to brownish lores; crown dull brownish-grey with buff shaft streaks, fading posteriorly; back and rump dull greyish-brown, uppertail-coverts slightly paler; wing-coverts rufous with blackish shaft streaks, remiges slightly darker with dark fuscous tips, contrastingly darker chestnut primary coverts; tail slightly rounded, shafts slightly stiffened basally, rather rounded tips, dark rufous; throat and malar area ochraceous yellow; breast light dull brownish with vague ochraceous tawny streaking that fades posteriorly, belly slightly paler, flanks and undertail-coverts dull, light greyish-brown; iris brown to dark brown; upper mandible dark brown to brownish, lower mandible paler, greenish-horn to yellowish-green; tarsus and toes yellowish-green to light greenish-olive. Sexes alike. Juvenile is slightly paler and duller throughout, throat darker, breast lacking or almost lacking streaks. Race diluviale was described as having browner, less greyish, upperparts, especially on rump and uppertail-coverts, much more buffy breast, browner (less greyish) sides, flanks and undertail-coverts.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Sister to P. rufum; some genetic studies (1, 2) suggest that the two are sister to genus Ancistrops. Race diluviale may represent E extreme of clinal variation of nominate; more thorough analysis required. Species name often spelt erythropterus, but must agree with neuter gender of genus. Two subspecies tentatively recognized.

Subspecies

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Tropical lowland evergreen forest and flooded forest; mostly terra firme and transitional forest, also várzea forest (possibly primarily so in N portions of range). Mostly below 500 m, locally to 1200 m.

Movement

Resident.

Diet and Foraging

Arthropods. Usually in pairs, almost always in mixed-species flocks, from mid-storey to canopy. Acrobatically gleans and pulls food items from live and dead leaves, sometimes twigs, usually towards ends of branches in outer shell of tree’s foliage.

Sounds and Vocal Behavior

Song a fast, buzzy, slightly accelerating, quavering or slightly descending trill, duration 2–3 seconds; call undescribed.

Breeding

No information.
Not globally threatened. Uncommon to fairly common. Density estimated at 4–5/km2 in transitional forest in SE Peru. Occurs in several protected areas, including Amacayacu National Park, in Colombia, and Manu National Park and Biosphere Reserve and Tambopata-Candamo Reserved Zone, in Peru.
