Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022).

Trend justification: Due to its dependence on forests, the species is in decline as its habitat is logged and degraded. Tree cover within the range is lost at a rate of 13% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is also found in tall secondary forest and plantations (Horton 2020), it is suspected that population declines are roughly equivalent to the rate of tree cover loss; they are here tentatively placed in the band 10-19% over three generations.
