Population justification: The population size has not been quantified, but the species is described as uncommon to fairly common (Schulenberg and Sedgwick 2020) and records are frequent and continuous throughout its small range (eBird 2022). Given its small range the population is however unlikely to be large, and an accurate quantification is urgently required.

Trend justification: The population trend has not been investigated, but the species is suspected to decline due to forest loss. Tree cover within the range is lost at a rate of 6% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Despite some tolerance of edge and secondary habitat, it requires the presence of tall mature forest (Schulenberg and Sedgwick 2020, J. Barrio in litt. 2023). As population declines may therefore be steeper than the rate of tree cover loss suggests, they are here placed in the band 10-19% over ten years.
