Secretarybird Sagittarius serpentarius is listed as Least Concern on the basis that it is not considered to approach the thresholds for Vulnerable under any of the IUCN criteria.
BirdLife International is aware of discussions on the African Raptors, African Birding and Tanzania Bird Atlas listserver groups since at least early 2010 in which views have been expressed that this species is possibly in rapid decline, at least in some parts of its range. In light of these comments, information on this species is requested to help in the assessment of its threat status.
Up-to-date estimates of population sizes at the national, regional or global level would be very useful; however, information on the likely rate of decline at any of these scales is regarded as particularly important, and details of likely threats and their impacts will also assist in the evaluation of this species’s status. To qualify as threatened under the A criterion, a decline in this species’s population must be observed, estimated, inferred or suspected in the past, future, or both, at a rate of at least 30% over 38 years (estimate of three generations) for Vulnerable and at least 50% over 38 years for Endangered. A rate of decline approaching 30% over 38 years would make the species eligible for uplisting to Near Threatened.
