Slaty-winged Foliage-gleaner

The slaty-winged foliage-gleaner (Neophilydor fuscipenne) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Colombia, Ecuador, and Panama. == Taxonomy and systematics == The slaty-winged foliage-gleaner was formally described in 1866 by the English naturalist Osbert Salvin based on a specimen collected in the province of Veraguas in the Republic of Panama. He placed the species in the genus Philydor and coined the binomial name Philydor fuscipennis. The specific epithet combines the Latin fuscus meaning "dusky" or "dark" with -pennis meaning "-winged". Studies published in 2011 and 2023 defined and resolved the polyphyly of the genus Philydor and proposed a new genus Neophilydor for the slaty-winged foliage-gleaner and rufous-rumped foliage-gleaner (N. erythrocercum). In 2024 the South American Classification Committee of the American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy adopted the new genus. However, as of December 2024 BirdLife International's Handbook of the Birds of the World retains the two species in genus Philodor. Two subspecies are recognized: N. f. fuscipenne (Salvin, 1866) N. f. erythronotum (Sclater, PL & Salvin, 1873) The species has a complicated taxonomic history. Since about 1990 it has been assigned the two subspecies…
