Larus fuscus graellsii/intermedius adult, June-July 2006-2008, Hortavær, Nordland, Norway. Picture: Morten Helberg.

Pale-mantled adults in Hortavær, Nordland. This Archipelago contains a pure population of dark fuscus birds, but sometimes a pale-mantled bird is seen here as well. Maybe there has been one breeding attempt of mixed fuscus type x pale-mantled bird.

More information about migration strategies in Norwegian fuscus and the ringing programme in the three northern counties of Norway: Nordland, Troms and Finnmark, can be found here: The summary for juveniles can be found in the fuscus 1cy October section, the summary for adults can be found in the fuscus adult October section.
Morten Helberg, Geir Systad, Ingve Birkeland, Nils Lorentzen & Jan Bustnes published an article about this research in Ardea 97, 2009, titled: Migration patterns of adult and juvenile Lesser Black-backed Gulls Larus fuscus from northern Norway. The complete PDF can be found HERE.
