| Population justification: In the Jequitinhonha valley (the sole currently known population), at least four birds were found in a 100 ha area, but it was thought unlikely that this density could be extrapolated for the whole 5,000 ha partly fragmented patch of forest (R. Ribon in litt. 2006). The latest surveys of the Macarani / Bandeira area near Balbina (Sossego do Arrebol Forest) found just six individuals: five females and a single male (Fundação Biodiversitas in litt. 2010), with likely no more than 10-15 birds in total and none found in other forest fragments surveyed (R. Ribon in litt. 2011). It is therefore now suspected that there may be fewer than 50 birds remaining, and the population is placed in the band 1-49 mature individuals. | ||||
| Trend justification: Suspected based on rates of habitat loss and degradation. | ||||
