Population justification: The species is described as fairly common and easily overlooked (Whittaker 2002). In Bolivia, densities of 1 pair/20-67 ha were observed (Whittaker 2002), which roughly equates to 3-10 mature individuals/km². Even under the conservative assumption that only 25% of forests within the range are occupied at this density (i.e., c. 400,000 km²; Global Forest Watch 2023), the global population is presumed to be large, likely numbering over 1,000,000 mature individuals.
The species' stronghold appears to be in the Amazon, and it is rarely observed in the Atlantic Forest where the population is likely to be comparatively small (Fjeldsa et al. 2020, eBird 2023).

Trend justification: The population trend has not been investigated, but the species is described as becoming rarer particularly in the Atlantic Forest part of the range, likely as a consequence of forest destruction (Fjeldsa et al. 2020).
Over three generations (19.5 years), 16% of tree cover is lost within the range (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). This value however does not account for habitat degradation and fragmentation, which are likely impacting this strictly forest-dependent species. It is therefore tentatively assumed that population declines exceed the rate of tree cover loss by half, amounting to 24% over three generations. Accounting for uncertainties, population declines are therefore here placed in the band 20-29% over three generations. Notably, the rate of population decline may vary across the range, given that habitat loss and degradation appear more severe in the Atlantic Forest than in the Amazon Basin (B. Phalan in litt. 2023).
