Population justification: There were thought to be some 7,000 birds in the Banggai Islands, mostly on Peleng, and as many as 38,000 (22,500-54,000) individuals on Taliabu, but these populations are suspected to be undergoing rapid declines, thus its total population is conservatively placed in the band for 10,000-19,999 mature individuals. This equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.

Trend justification: This species is known to be suffering extensive habitat loss and degradation and intensive hunting pressure (Rheindt 2010). Furthermore, there is evidence of declines on Taliabu, Peleng and associated islets, including a substantial fall in encounter rates on Taliabu (Rheindt 2010) compared with work conducted in 1991 (Davidson et al. 1991). Its population is thus suspected to be undergoing at least a rapid decline.
