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. Tree cover loss is low within the range (2% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species also occurs in selectively logged forests (Brewer 2020); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
