Population justification: The global population size has not been quantified, density descriptions range from uncommon to fairly common (Stotz et al. 1996, Zimmer and Isler 2020).

Trend justification: Tree cover loss is negligible within the range (1% over ten years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
