Résumé :	Genetic analyses of the relationships among different forms of Lesser Black-backed Gull Larus fuscus, Herring Gull L. argentatus and Yellow-legged Gull L. cachinnans are beset with difficulties, associated with apparently low levels of genetic divergence, inbreeding, and the highly unstable nature of gull populations. This short review summarises and discusses a new attempt to tackle this problem (de Knijif et al. 2001). While the results do not solve the 'gull problem', they have provided much new evidence on the extent of genetic variation among different individuals of the same taxon, which will be crucial to any future consideration of gull taxonomy.
