Description wikipedia

The Alagoas foliage-gleaner (Philydor novaesi) is an extinct passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It was endemic to Brazil. == Taxonomy and systematics == The Alagoas foliage-gleaner was first collected in 1979 at Murici in Alagoas and was formally described in 1983. Based on its morphology and observed behavior it was placed in genus Philydor. It and the very similar black-capped foliage-gleaner (P. atricapillus) are treated as a superspecies. The Alagoas foliage-gleaner's specific epithet commemorates the Brazilian ornithologist Fernando da Costa Novaes. == Observational history == The Alagoas foliage-gleaner was discovered in 1979 in Murici, Alagoas. Between then and 2009 at least five further sightings came from that site; one was of four individuals and the others of one each. In 2003 up to four were seen at a second site, the private preserve RPPN Frei Caneca in Pernambuco, about 50 km (31 mi) north of Murici. There was one undocumented sighting at a private preserve adjoining Frei Caneca in 2004. Sightings, some accompanied by photographs and sound recordings, continued at Frei Caneca until 2011. The last documented sighting of the species was there on September 13, 2011, when the bird was video recorded. The last apparent sighting was also at Frei Caneca, in April 2012, but it was not documented.
