Sao Tome Scops-owl (Otus hartlaubi): Revise global status?

This discussion was first published as part of the 2021 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2022 Red List update this post remains open and the date of posting has been updated.

    The status of this species was recently discussed, there is no new data to justify the proposed change, and therefore criteria D1 should still apply. On the other hand, I also see no justification that this species is restricted to a single location while the Sao Tome Oriole is considered to occur in 11-100 locations. Both of these species are restricted to forest and are subjected to similar threats, so I suggest that the VU status is maintained (for both).

    It would be useful to provide more detail (including references) on how population estimates, AOO and EOO were obtained for this species (and please see comment on the forum discussing the proposed status change for the Sao Tome oriole).

    A project is planned to start soon, aiming to assess the diet of introduced mammals in Sao Tome, which hopefully will finally clarify the role that these might be posing as predators of endemic species, like the Sao Tome scops-owl.

    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.

    I would greatly appreciated if you could provide a thorough reply to my previous comments.
    It is baffling that this proposed changed is not based on any new data, considering that the status of relevant São Tomé endemics was reviewed recently to ensure coherent application of criteria, which is now at risk by these ad hoc changes.

    Recommended categorisations to be put forward to IUCN

    Based on available information, our proposal for the 2021 Red List is to pend the decision on this species and keep the discussion open until 2022, while leaving the current Red List category unchanged in the 2021 update.

    Many thanks for everyone who contributed to the 2021 GTB Forum process. 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.
