Population justification: The global population size has not been quantified, but the population on Buru is estimated as 382,000 individuals and the population in the proposed Lolobata Reserve in north-eastern Halmahera is estimated as 22,100 individuals (Gibbs et al. 2001). However these two areas represent only a small proportion of the species's global range so the total has been put in the band 500,000-999,000 individuals.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
