Larus fuscus fuscus 2cy, June 14 2014, Tara dump - Tampere, Finland. Images: Hannu Koskinen. 2cy in June from the "slow moulting" group. This group contains birds photographed in Finland, of which at least several birds recall nominate fuscus in many respects, except for (some) juvenile primaries. In this way they are different from 'typical 2CY fuscus birds', which return in Europe with replaced, 2nd gen primaries in spring. Bird below: similar to advanced 2CY western intermedius, but probably slow moulting fuscus. All coverts and tertials were replaced in winter and all rectrices and secondaries as well. Primaries are still juvenile. White head and underparts. Complete moult not started yet, P1 old. Few coverts (especially central MC) now replaced for 3rd gen, blackish like in nominate fuscus.
