Résumé :	The Audouin Gull Larus audouinii breeds since 1990 at Aspretto in the Gulf of Ajaccio (Corsica). From 2000 to 2009, 293 nestlings were ringed (colour marks with letters). The sightings and controls in Corsica and abroad of marked birds allowed to study their migration, dispersal, survival and philopatry. Moreover the controls at the Corsican colony of birds ringed mostly in Italy but also in Spain showed the exchanges between West Mediterranean colonies. We also estimated the age at first reproduction, the breeding success in relation to age and the sex ratio of breeding birds born in Corsica.
