Population justification: The global population is suspected to number 5,000,000-49,999,999 mature individuals (Partners in Flight 2022).

Trend justification: The population trend has not been investigated. The only threat known to this forest-dependent species is the loss and degradation of its habitat. Tree cover loss within the range is low (4% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely similarly low; they are here tentatively placed in the band 1-9% over three generations.
