Résumé :	According to a recent ICBP International Newsletter, Audouin’s gull, Larus audouinii Payraudeau 18 26, is the Mediterranean’s most important bird. It is the Mediterranean’s only endemic breeding seabird. In 1977 Hans H. Witt estimated the world population size to be between 600–800 pairs. IUCN/WWF, in 1978, initiated a programme to promote the conservation of Audouin’s gull throughout its range. Largely as a result of the more detailed surveys which insued, current estimates suggest that there are at least 4,000 pairs in the breeding population. As part of this project a three year study of the factors affecting the reproductive output of this rare gull species has been undertaken at, what is numerically, the most important breeding site. In this paper the breeding success or failure of Audouin’s gull is discussed and the factors which influence reproductive success are described. A management plan is also suggested which would safeguard and perhaps improve the productivity at the colony in future seasons.
