Justification of Red List category

This species is precautionarily maintained as Vulnerable. Existing demographic studies of populations in France and Malta indicate a population decline, caused by low breeding success due to predation by introduced mammals and low adult survival owing to fisheries bycatch and predation. However, some more recent studies have shown population increases and there may be large as yet undiscovered colonies in the Eastern Mediterranean or the Black Sea. If further study and monitoring provide evidence of large stable or increasing populations, the species may warrant downlisting in the future.
