Population justification: The global population size has not been quantified, but the species is described as 'fairly common' (Stotz et al. 1996). Given the number of records within its large range (per eBird 2021) it is unlikely that the population numbers below 10,000 mature individuals.

Trend justification: The population trend was reported to be stable, as the species's preference for dense forest edge and secondary growth may buffer the impact of tree cover loss (Carter 2020). However, tree cover loss has been accelerating since 2016, to a rate equivalent to 10% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Moreover, the species may be subject to trapping pressure (A. Lees in litt. 2011). Therefore, while the population may have been stable until recently, it is feared that the population is now starting to decline slowly, at a rate not exceeding 10% over three generations.
