Rufous-tailed Foliage-gleaner

The rufous-tailed foliage-gleaner is 16 to 17 cm (6.3 to 6.7 in) long and weighs 21 to 32 g (0.74 to 1.1 oz). It is a medium-sized furnariid with a wedge-shaped bill. The sexes have the same plumage. Adults of the nominate subspecies have a wide ochraceous buff eyering, a narrow buff-yellow supercilium, a dark olive line behind the eye, olive-brownish lores and ear coverts with yellowish buff flecks and streaks, and a buff-yellow malar area. Their crown is dark olive with faint paler spots and streaks toward the rear, their back and rump are dark olive with pale streaks on the upper back, and their uppertail coverts are dark olive with rufous tips. Their tail is rufous. Their wings are mostly dark olive-brown, with darker brown primary coverts. Their throat is buff-yellow with some irregular darker inclusions, their breast dull buff yellow with indistinct olivaceous streaks, their belly dull buff yellow with very faint streaks, and their flanks and undertail coverts slightly darker and more olivaceous. Their iris is brown, their maxilla blackish to grayish horn, their mandible paler greenish gray to olive-green, and their legs and feet yellowish brown to olive-green. Juveniles have a more apparent and ochraceous supercilium, browner (less olive) upperparts, and darker less yellowish underparts than adults. Subspecies A. r. …

The nominate subspecies of the rufous-tailed foliage-gleaner is found in southeastern Amazonian Brazil, southeastern Peru, and northern Bolivia. A. r. subflavescens is found in northeastern Ecuador and eastern Peru. A. r. flavipectus is found in southeastern Colombia, southern Venezuela, Guyana, Suriname, and northeastern Brazil. A. r. flavipectus might also occur in French Guiana, but the South American Classification Committee of the American Ornithological Society terms it hypothetical there because the records are not documented. The rufous-tailed foliage-gleaner inhabits tropical lowland evergreen and seasonally flooded forest. It primarily occurs in terra firme forest but also locally in tall várzea forest. In elevation it mostly occurs below 850 m (2,800 ft) but reaches 900 m (3,000 ft) in Brazil and 1,300 m (4,300 ft) in Venezuela.

The rufous-tailed foliage-gleaner feeds on a variety of arthropods including Orthoptera, Coleoptera, Heteroptera and spiders. It forages singly and in pairs, almost always as part of mixed-species feeding flocks. It forages from the forest's mid-storey to its canopy. It gleans its prey, especially from dead leaves but also from live foliage, epiphytes, vines, and moss.
