Population justification: Any remaining extant population is likely to be extremely small, probably numbering far fewer than 250 mature individuals, and precautionarily assumed to form a single subpopulation.

Trend justification: An ongoing population decline is suspected to be occurring in line with habitat degradation and the conversion of forest to agricultural land throughout the species's range; barely any natural forest now remains on Sangihe.
