5 thoughts on “Grey Imperial-pigeon (Ducula pickeringii)”
The distribution as shown in the map for the Sulu archipelago is greatly exaggerated. There have never been any surveys of most of those islands, and most of the rest not since Mearns was there. According to Global forestwatch there has been significant forest cover loss since 2000 on some islands that still had forest eg Capual. On the other hand there seems to be a good population on Cagayancillo with many on Calusa. I think it is still data deficient in the Philippines in terms of breeding range.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 25 April 2025. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List category on this page on 25 April 2025, when discussions will re-open.
We thank D. Allen for their comment. A change to the range map will be considered, with islands with unconfirmed records changed to ‘possibly extant’ where appropriate. While this will revise the range map, it does not change the inference of this species’ extinction risk.
Based on available information, our preliminary proposal for the 2025 Red List would be to adopt the proposed classification outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 4 May 2025, after which the recommended categorisations will be put forward to IUCN.
The final 2025 Red List categories will be published on the BirdLife and IUCN websites in October 2025, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Grey Imperial-pigeon is recommended to be listed as Near Threatened, approaching thresholds under Criterion B2ab(ii,iii).
