Population justification: The global population is suspected to number 500,000-4,999,999 mature individuals (Partners in Flight 2022).

Trend justification: The population trend has not been investigated. Tree cover within the range is lost at a rate of 5% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is thought to be moderately sensitive to habitat degradation (Zimmer and Isler 2020). Population declines are therefore tentatively placed in the band 1-9% over ten years.
