Slaty-winged Foliage-gleaner Philydor fuscipenne Scientific name definitions

The Slaty-winged Foliage-gleaner was formerly treated as a subspecies of the exclusively Amazonian ranging Rufous-rumped Foliage-gleaner (Philydor erythrocercum), and it seems probable that these two species are each other’s closest relatives. The present species ranges from central Panama to northern Colombia, and south over the Pacific slope to western Ecuador, where it ascends the foothills locally as high as about 1200 m. It inhabits lowland evergreen forest and taller second growth, where it joins mixed-species foraging flocks in the undergrowth and midstory. Two subspecies of the Slaty-winged Foliage-gleaner are generally recognized, which differ in overall depth of the underparts and tail color.

17 cm; 25–28 g. Rather dark Philydor. Nominate race has vague eyering pale rufescent ochre, conspicuous supercilium pale rufescent ochre, darkening posteriorly, postocular band dull dark brownish, auriculars and band below eye dull dark brownish with dull rusty flammulations, lores grizzled fuscous and buff; crown dark brown with very faint dark rufescent shaft spotting, indistinct dark rusty-rufous collar extending to side of neck; back rich rufescent brown, becoming chestnut-rufous on rump and uppertail-coverts; wing-coverts dull brown, primary coverts dark slaty brown, remiges slaty grey-brown; tail rounded, shafts slightly stiffened basally, somewhat rounded tips, rufous-chestnut; throat orange-buff to tawny-orange or bright rusty; underparts similar, slightly deeper rufescent on central breast, progressively duller and slightly paler towards belly, side of upper breast browner, sides and flanks to undertail-coverts darker rufescent brown or chestnut-brown; iris brown; upper mandible grey to blackish, lower mandible grey to horn; tarsus and toes grey-green to greenish-yellow. Sexes alike. Juvenile is generally more rufous, with ochraceous underparts. Race erythronotum is paler and duller throughout, in Ecuador more ochraceous below.

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.

Tropical lowland evergreen forest, usually hilly, also tall second growth; mainly 500–1000 m, locally to 1200 m.

Resident.

Diet primarily Orthoptera, spiders and their eggs, and Coleoptera; Heteroptera and small lizards also recorded. Forages solitarily or in pairs, usually in mixed-species flocks, from undergrowth to lower mid-storey. Usually works along or climbs up branches; acrobatically gleans arthropods from dead leaves and epiphytes; probably a dead-leaf specialist.

Song a monotonic accelerating trill; contact call a sharp “chef”.

No information.

Not globally threatened. Fairly common to rare; uncommon to locally fairly common in Panama. Rare to locally fairly common in W Ecuador, and occurs in Río Palenque Science Centre; disjunct population in that country considered vulnerable because of extensive destruction of lowland forests.
