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 6% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests, the species is sometimes also found in secondary forest and plantations (Farnsworth and Lebbin 2020); consequently, population declines may roughly be equivalent to the rate of tree cover loss. Tentatively, population declines are here placed in the band 1-9% over ten years.
