Assessment status criteria
D
Assessment rationale/justification
The UAE is situated on the edge of the species range, and occurrence and numbers may be somewhat variable as a result. Nevertheless, counts of this species on pelagic bird trips suggest that the non-breeding visiting population of this species may be very small (100-600 mature individuals). This qualifies the species for listing as Endangered under criterion D.

Threats listed in assessment
Seabirds, including this species, were formerly exploited for food and medicinal use (at a subsistence level [Al-Saghier et al. 2000]) on the Halaaniyaat islands (Gallagher 1985) and Socotra (Al-Saghier et al. 2000, Porter et al. in prep.), but this practice appears to be discontinued due to the availability of cheap poultry and the danger of climbing the cliffs (Taleb 2002). Non-native predators (e.g. rats Rattus spp. and Feral Cats Felis catus) are probably a limiting factor on the species' breeding population size (Al-Saghier et al. 2000), although their impact on the Socotran subpopulation may have stabilised long ago, given the long period (over 2,000 years) of coexistence. Mortality and ecosystem degradation resulting from marine oil spills are potential threats.
