Population justification: The global population is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2022); thus it is here placed in the band 20,000-49,999 mature individuals.

Trend justification: The population trend has not been investigated. Within the range, tree cover is lost at a rate of 11% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The species occurs in a variety of habitats, including forest, edge, as well as shrubby and open woodland (Joseph 2020); consequently, population declines may be slower than the current rate of tree cover loss suggests. Tentatively, population declines are here placed in the band 1-9% over ten years.
