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 most recent estimate for the European population is 43,000-44,000 mature individuals (BirdLife International 2015). The global population is 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. The European breeding population has increased substantially over the last three generations (39 years, based on a generation length estimated by BirdLife to be 13 years) (BirdLife International 2015). Since 2000, numbers have remained stable overall, with continued increases in some western and central Mediterranean countries, declines in a few eastern Mediterranean countries, and fluctuations in Spain, which holds c. 90% of the European population.
