Socotra Buzzard Buteo socotraensis is recognised as a valid species following Porter and Kirwan (2010).
Porter and Kirwan (2010) recommended that the species be listed as Vulnerable under criterion D1 on the basis that the population is estimated to number fewer than 1,000 mature individuals. Surveys carried out between 1999 and 2008 suggest that there is a population of fewer than 250 pairs (Porter and Suleiman in prep., cited in Porter and Kirwan 2010), equating to perhaps fewer than 500 mature individuals. It is known that nestlings of this species are sometimes mistakenly taken for the falconry trade; however, there is no evidence of a decline in the population (Porter and Kirwan 2010) and insufficient data on this and any other potential threats to infer a decline, so the population is suspected to be stable pending further studies.
Comments are invited on this proposed listing, along with any additional information on the species.
