Plain-winged Woodcreeper

The plain-winged woodcreeper or thrush-like woodcreeper (Dendrocincla turdina) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Paraguay. == Taxonomy and systematics == The plain-winged woodcreeper's taxonomy is unsettled. The International Ornithological Committee (IOC) and the Clements taxonomy assign it two subspecies, the nominate D. t. turdina (Lichtenstein, MHC, 1820) and D. t. taunayi (Pinto, 1939). BirdLife International's Handbook of the Birds of the World (HBW) treats it as monotypic and treats subspecies taunayi as a subspecies of the plain-brown woodcreeper (D. fuliginosa). Previously both subspecies were widely considered subspecies of the plain-brown woodcreeper. This article follows the two-subspecies model. == Description == The plain-winged woodcreeper is 19 to 21 cm (7.5 to 8.3 in) long and weighs 23 to 45 g (0.81 to 1.6 oz). The species is a medium-sized member of its genus, with a short straight bill. The sexes have the same plumage but females are significantly smaller than males. The nominate subspecies is mostly olive-brown. Its crown has faint buff streaks, its throat is pale buff, and its flight feathers, uppertail coverts, and most tail feathers are slightly rufescent. Its wing linings are ochraceous buff.…
