Chestnut-winged Foliage-gleaner

The chestnut-winged foliage-gleaner (Dendroma erythroptera) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. == Taxonomy and systematics == The chestnut-winged foliage-gleaner's taxonomy is unsettled. The International Ornithological Committee (IOC) and the Clements taxonomy follow the conclusions of a 2011 publication that moved the species from genus Philydor to Dendroma. BirdLife International's Handbook of the Birds of the World (HBW) retains it in Philydor. According to the IOC and Clements, the chestnut-winged foliage-gleaner shares genus Dendroma with the buff-fronted foliage-gleaner (D. rufa), and they and the chestnut-winged hookbill (Ancistrops strigilatus) are sister species. HBW retains the buff-fronted foliage-gleaner in genus Philydor with the chestnut-winged and several other foliage-gleaner species, and does not agree with the above sister species treatment. The three taxonomic systems agree with assigning two subspecies to the buff-fronted foliage-gleaner, here listed using genus Dendroma. (HBW retains the neuter spellings of the specific epithets instead of the feminine ones required by Dendroma.) They are the nominate subspecies D. e. erythroptera (Sclater, PL, 1856) and D. e. diluvialis (Griscom & Greenway Jr., 1937). == Description == The chestnut-winged foliage-gleaner is 17 to 19…
