Revision of the range of the Rio de Janeiro Antbird Cercomacra brasiliana Hellmayr, 1905 (Aves: Passeriformes: Thamnophilidae)

Abstract

We present a review on the range of the endemic and near-threatened Rio de Janeiro Antbird Cercomacra brasiliana, based on new field records and extensive search in literature, museums and bird sound databases. Our records extend the species’ known range over 200 km westwards to the hinterlands of Minas Gerais state. Nevertheless, no records were done within federal or state reserves, and the conservation of the remaining forest fragments where the species was recorded is urgent.
