Population justification: The species is described as 'rare' (Stotz et al. 1996), and Partners in Flight (2022) suspect the population to number less than 50,000 mature individuals. However, based on observational records (see eBird 2022), this may be a considerable underestimate. Tentatively, the population is here placed in the band 50,000-99,999 mature individuals, though an accurate quantification of the population is urgently required.

Trend justification: The population trend has not been investigated, but due to its dependence on primary forests the species may be negatively affected by forest loss and degradation. Tree cover within the known range is lost at a rate of 3% over three generations (10.3 years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Despite its strict habitat requirements, population declines are unlikely to considerably exceed the rate of tree cover loss; they are here tentatively placed in the band 1-19% over three generations.
