Population justification: The estimate of 9,000-18,500 individuals (roughly equivalent to 6,000-12,000 mature individuals) is based upon survey data (Belmonte-Lopes unpublished data) which estimated 20-40 individuals/km2 over 460 km2 (10% of the Extent of Occurrence).

Trend justification: Few remaining habitat fragments occur within protected areas. Forest loss within the species's range has been estimated at c.3.7% over 3 generations (c.11 years) (Tracewski et al. 2016). Therefore, the rate of decline in this species is suspected to be <10% over 3 generations.
