Résumé :	In this paper we describe the status of the Lesser Black-backed Gulls Larus fuscus breeding in the Horsvaer archipelago, an important colony in northwest Norway, from which at least 14 colour-marked individuals have been sighted in Britain. The birds' plumage, long wings and general appearance match the characters of 'Baltic Gull' L. f. fuscus; the migration patterns and moult strategy of the 'Horsvaer gulls' are also consistent with nominate fuscus from the core parts of the breeding range. In our opinion, the Lesser Black-backed Gulls from the Horsvaer colonies are best treated as pure L. f. fuscus.
