Population justification: Gutiérrez and Guinart (2008) reported a global population of 21,161 pairs. However, more recent figures point to a total of 21,300-22,300 pairs, of which 21,080-21,310 pairs are in Europe. The global population is therefore estimated to number 63,900-66,900 individuals (G. Eken in litt. 1999, N. Baccetti in litt. 2008, D. Portolou in litt. 2010).
Trend justification: The population has expanded owing to increased availability of fisheries discards close to key breeding colonies. Current fishery practices are unsustainable and may result in collapse in the fishery in the future. This would induce population declines in Audouin's Gull.
