Population justification: The global population size has not been quantified, but the species is described as generally scarce, although locally common in north-eastern New Guinea (del Hoyo et al. 1992).
Trend justification: There are no data on population trends; however, the species is thought to be in decline, owing to habitat loss, degradation and hunting.
