    If the species range map is to be believed, then the species did indeed go extinct on Mauke, while HBW also reported it, historically, from Aitutaki and Mangaia (fossil record). So, the chances of extirpation from an island the size of Atiu is not unrealistic – we don’t know what caused those extirpations. So, I would urge caution on that front – there is evidence that bullets 6 and/or 7 have happened in the past..

    Two populations have already disappeared in the past, on Mangaia and Mauke (see Thibault, J.-C. and Cibois, A. 2017. Birds of Eastern Polynesia. A biogeographic Atlas., Barcelona, Lynx Edicions). Although the remaining populations seem stable, no evaluation has been made recently. Both Atiu and Rarotonga are relatively small islands, and the trends are unknown regarding the wooded areas where the fruit doves live. So the main risks, like possible habitat loss, introduction of competitors or diseases, have not decreased for this species. Therefore I would not recommend a category change for this species.
