Population justification: The global population size has not been quantified, but the species is described as uncommon to fairly common throughout its range (del Hoyo et al. 2003, Zimmer et al. 2020).

Trend justification: The population trend has not been investigated. Tree cover within the range is lost at a rate of 4% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species occurs in a variety of edge, secondary and converted habitats (Zimmer et al. 2020). Consequently, the current rate of tree cover loss may not be affecting the population; in fact, the species may benefit from low rates of deforestation as it is opening up new habitats. In the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
