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 (BirdLife International 2001).  However, encounter rates reported by Rheindt (2010) were far lower than those found in the early 1990s (Davidson et al. 1991). Hence these populations are suspected to be undergoing rapid declines. Conservatively, the total population is now placed in the band 10,000-19,999 mature individuals, assumed from a total population of between 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). There has been forest loss and degradation throughout virtually the whole range, but in small patches, such that the overall percentage forest cover lost is estimated at 12% between 2001-2019 (Global Forest Watch 2021), equivalent to almost 13% over three generations. The pervasive nature of the habitat conversion in lowland areas does however facilitate hunting and egg-collecting across almost the entire range of the species. Rheindt (2010) reported a substantial fall in encounter rates on Taliabu when compared with fieldwork carried out in 1991 (Davidson et al. 1991), and reported declines on Peleng and associated islets. Its population is thus suspected to be undergoing a rapid decline.
