Population justification: The global population size has not been quantified, but density descriptions range from locally uncommon to fairly common (Stotz et al. 1996, Clock 2020, Silveira et al. 2023).

Trend justification: A slow population decline is suspected owing to habitat loss and fragmentation. Tree cover within the range is lost at a rate of 6% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is restricted to forests and mature secondary growth, it shows some tolerance of habitat disturbance (Silveira et al. 2023). Population declines are therefore likely slow and localised; they are here tentatively placed in the band 1-9% over ten years.
