  1. No new information on this species have been provided from within the IUCN SSC Pigeon and Dove Specialist Group network and we are therefore supportive towards the proposed reassessment and changes in Red List status.

  2. Red List Team (BirdLife International) says:

    Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed. We will analyse and interpret the new information and post a preliminary decision on this species’s Red List status on this page in early July.

    Thank you once again,
    BirdLife Red List Team

    Preliminary proposal

    Based on available information, our preliminary proposal for the 2021 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.

    There is now a period for further comments until the final deadline in mid-July, after which the recommended categorisations will be put forward to IUCN.

    The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.

    The following comment has been received from Guy Dutson by email:

    • evidence for recent increase = anecdotal records from birding tours (which is generally the only fieldwork on Makira) and my personal more detailed observations (the most recent of which were published in Mittermeier et al)
    • evidence for total population size = I support the precautionary conclusion of <11,000 mature individuals, moderated by a low risk tolerance
    • surely >1000 on Makira based on the suite of records presented
    • a continuing decline based on the rate of commercial logging, possibly >30% over 20 years
    • Note that remote sensing isn’t usually accurate at detecting logging
    • Although the species is ‘tolerant’ of forest degradation, this tolerance is biased by the increased detectability in degraded forest, and this is based on moderate degradation whereas some recent logging is causing severe degradation
    • Need better data on logging on Makira – I think that a decline of >30% over 20 years is plausible based on logging

    Recommended categorisation to be put forward to IUCN

    The final categorisation for this species has not changed. Chestnut-bellied Imperial-pigeon is recommended to be listed as Near Threatened, approaching the threshold for listing as threatened under Criterion C2a(i).

    Many thanks for everyone who contributed to the 2021 GTB Forum process. The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.
