Tag Archives: Rio de Janeiro Antbird
Rio de Janeiro Antbird Cercomacra brasiliana is listed as Near Threatened under criterion B1a+b(i,ii,iii,v) on the basis that it was known from fewer than 10 locations within a moderately small range, in which it was generally considered rare or uncommon, with numbers probably declining. Following on from improved knowledge of its distribution in areas where it had previously been overlooked (del Hoyo et al. 2003), the species’s Extent of Occurrence has been updated by BirdLife.
