Population justification: No population density estimates are available, but the population size is suspected to be greater than 10,000 mature individuals (Buchanan et al. 2008; Davis et al. 2018). The species has been recorded frequently during surveys on New Britain, although the frequent records in hill forests may have resulted from the species's tendency to fly large distances, and may obscure a dependency on coastal and riparian habitats (Davis et al. 2018).
The species has a large range, with an estimated 39,000 km2 of tree cover with at least 50% canopy cover within its range in 2010, although this figure is likely to include oil palm plantations (Global Forest Watch 2021). Based on the first quartile and median recorded densities of congeners (14.5 and 38 individuals/km2, respectively), the area of tree cover stated above, and assuming that 10-25% of available tree cover is occupied, the population size is tentatively suspected to fall in the range 57,000 - 373,000 individuals, roughly equating to 38,000 - 249,000 mature individuals.
The subpopulation structure is not known, but the species has a fairly high dispersal ability, and occurs on a large number of islands. The number of subpopulations is suspected to fall within the range 2-20.
Trend justification: Over 19 years from 2000 to 2019, approximately 9.6% of tree cover with at least 50% canopy cover was lost from across the species's range (Global Forest Watch 2021). Extrapolating over 21 years (three generations), an estimated 11% of tree cover was lost from the species's range, and 12% is suspected to be lost over the next three generations. However, the estimated rate of tree cover loss was higher over the past few years, particularly in 2015 (Global Forest Watch 2021). Based on the rate of tree cover loss over the period 2014-2019 alone, it may be suspected that 20% of tree cover will be lost over the next three generations.
The impact of forest loss and degradation on the species is not known, and the species may experience declines as a result of forest degradation in addition to forest loss (Buchanan et al. 2008), although it has been recorded in high numbers in degraded forest (Davis et al. 2018). The population is therefore suspected to have undergone a reduction of 6-16% over the past three generations, and it is suspected to undergo a reduction of 7-25% over the next three generations.
