Range DescriptionFormicivora erythronotos survives in a narrow coastal strip around the BaÃa da Ilha Grande in south Rio de Janeiro, Brazil. Although known from c.20 specimens collected in the 19th century, it was unrecorded for over 100 years until its rediscovery in 1987. It has been subsequently found at a further seven sites (Buzzetti 1998, E. MendonÃ§a and L. P. Gonzaga in litt. 2000). The main localities are ArirÃ³ (densities of 89 pairs/km2) and Vale do Mambucaba (156 pairs/km2) (MendonÃ§a and Gonzaga 1999b). Smaller numbers have also been recorded at BracuÃ, Frade, SÃ£o GonÃ§alo, Taquari and Barra Grande (Buzzetti 1998, MendonÃ§a and Gonzaga 1999b, E. MendonÃ§a and L. P. Gonzaga in litt. 2000).
