Population justification: Based on extensive surveys across the range, it is estimated that the population numbers less than 2,500 mature individuals (ICMBio 2018). It is here placed in the band 1,000-2,499 mature individuals.
The species is restricted to isolated forest fragments and observational records are scattered across the range (ICMBio 2018, eBird 2022). The species has low dispersal abilities and has not been observed crossing large gaps between forests; it is therefore assumed that it forms several very small subpopulations, the largest of which does not exceed 250 mature individuals (ICMBio 2018).

Trend justification: The species is described as rare and confined to small subpopulations in disjunct patches of forest, which are isolated from each other due to the species' inability to cross gaps of open habitat between forests (IMCBio 2018). It is therefore inferred that the population is in decline on the basis of reductions in forest cover and increasing fragmentation between populations.
Within the range, 4% of tree cover is lost over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). As patches of suitable habitat are scattered and isolated, and as the species has only limited dispersal abilities (ICMBio 2018), population declines may exceed the rate of tree cover loss due to the additional impact of habitat fragmentation. Tentatively, population declines are here placed in the band 10-19% over ten years, but an accurate quantification of the trend is urgently required.
