Population justification: This species is generally described as 'common' (Stotz et al. 1996) and locally common anywhere above 1,600 m in Serra dos Orgaos National Park and Tres Picos State Park, Rio de Janeiro State (A. Foster in litt. 2013). A preliminary estimate based on the area of the species's mapped range, recorded population density estimates of close relatives and the fact that only a proportion of the mapped range is likely to be occupied gives an estimated population size of 6,000 - 58,400 mature individuals.

Trend justification: Despite a lack of data on population trends, a slow to moderate decline is suspected owing to habitat degradation in parts of the species's range, as well as the effects of population isolation due to extreme fragmentation. Some local populations in Rio de Janeiro state appear to have been stable since c.2003 (A. Foster in litt. 2013), implying that the overall rate of decline is not rapid or moderately rapid. An analysis of deforestation from 2000 to 2012 found that forest within the species's range was lost at a rate equivalent to 3% over three generation lengths (Tracewski et al. 2016). The population is therefore suspected to have undergone a reduction of 1-19% across three generations and is assumed to decline at the same rate over the next three generations.
