Taxonomy

This species was first discovered in 1979 at Murici in Alagoas, although there have been few sightings in that area since. In 2003 it was discovered at the Frei Caneca Private Reserve in Pernambuco. Due to its rarity it has been classified by BirdLife International as critically endangered. The current population is estimated to be between 50 and 249.

It is a member of the South American bird family Furnariidae, a group in which many species build elaborate clay nests, giving rise to the English name for the family of "ovenbirds".

Description

The Alagoas foliage-gleaner is 18 cm long and weighs 30–38 g with plain rufous-brown plumage. Sexes are similar. It inhabits interior upland forest at 400–550 m, and has been found singly, in pairs or small groups, and often join mixed-species flocks including lesser woodcreeper.

Habitat scarcity

The major threat to its existence is habitat destruction, and the clearance of Atlantic forest in Alagoas and Pernambuco has left few other sites likely to support populations of this species. A 2018 study citing bird extinction patterns and the lack of any confirmed sightings since 2011 recommended reclassifying the species as Extinct, and in 2019, the IUCN classified it as so.[2]

The binomial of this bird commemorates the Brazilian ornithologist Fernando da Costa Novaes.
