Justification of Red List Category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
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.
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
