Population justification: The population size of this species has not been formally estimated. It is described as 'scarce' by Lambert (1994) and 'uncommon' by Eaton et al. (2021) but is an elusive species that is easily overlooked (Bashari 2011, Mittermeier et al. 2013). Nonetheless, with only 1,200 km² of forest within its range (per Global Forest Watch 2023), and suggestion that it is uncommon, it is possible that its population size is relatively small. Precautionarily, the population size is therefore placed in the bracket of 2,500-10,000 mature individuals, but this requires confirmation.

Trend justification: This species is believed to be strictly dependent on lowland forest (Eaton et al. 2021). In the three generations (c.12 years; Bird et al. 2020) to 2022, forest cover in this species' mapped range reduced by 15% (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). Although it is at least somewhat tolerant of degradation, most habitat losses on Obi have amounted to total clearance to make way for mines and large-scale plantations. As a frugivore, that appears to be at least partially nomadic, it may depend on a network of feeding sites that vary spatially and temporally, making it especially vulnerable to habitat losses. Moreover, as a large-bodied species, it may be subject to some hunting pressure, although this species is elusive and other large-bodied species (e.g. other pigeons) on Obi are relatively common; hence hunting is considered only a minor threat. Overall the species is suspected to have declined by 15-25% over the past three generations, and the same rate is precautionarily suspected to occur in the future, with no mitigation of threats apparent and none of Obi's lowland forests protected (UNEP-WCMC and IUCN 2023).
