    I agree with bringing back this species to the Critically Endangered category. I personally did not support the downlisting of the species into the Endangered category for the reasons that are put forward now to uplist it again. A very small population, with threats from habitat degradation on the outer limits of its range. A survey to assess current distribution and densities to estimate the species trends is required. Annual monitoring transects along paths based on across the species range that had been set up in 1996-1997 for rangers operating in the Morne Seychellois National Park but also in other parts of its range (Rocamora 1997; initially conducted by ministry of Environment staff, now Seychelles National Park Authority only operates within MSNP) were stopped in 2002, and could be resumed. These were very simple but were sufficient to bring minimum information to have an insight about the trends of the species. More detailed monitoring recommended by Currie et al. 2004 was, to my knowledge, never implemented. From my personal experience the species appears more difficult to find and less abundant in the lower limits of its range (several territories have disappeared for example at Fairview, La Misère and Souvenir, and above Port Glaud, although the species continues to be present in undisturbed adjacent areas) probably due to cutting of large trees for housing development and road construction, disturbance from expanding residential areas with increasing numbers of invasive Common Mynas, a nest-site competitor that as a result probably penetrates deeper into adjacent secondary forests occupied by the Seychelles 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,

    Preliminary proposal

    Based on available information, our preliminary proposal for the 2021 Red List would be to list Seychelles Scops-Owl as Critically Endangered under Criteria B1ab(ii,iii,v); C2a(ii).

    With new information about the disappearance of some territories and ongoing habitat degradation, a continuing decline is inferred in the number of mature individuals, and in the AOO. As several territories are reported to have disappeared, it is assumed that several pairs have disappeared also, and the population size estimate has therefore been lowered to 240-274 mature individuals to reflect this.

    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.

    Recommended categorisation to be put forward to IUCN

    The final categorisation for this species has not changed. Seychelles Scops-Owl is recommended to be listed as Critically Endangered under Criteria B1ab(ii,iii,v); C2a(ii).

    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.
