Population justification: The global population size has not been quantified, but it is described as very scarce or rare (Clement 1999, Allen 2020). It is known from only a few records from Mount Apo and Mount Kitanglad, Mindanao, however its range is highly inaccessible; the elevations at which it occurs are rarely accessed by birdwatchers and there have been few expeditions that have sampled above the treeline.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. Although climate change has been identified as a potential threat, it remains unknown whether this is affecting or likely to affect the species.
