Feather patterns and the rather pale grey lower scapular do not fit the average Baltic Gull, yet the replaced P1-8 are indicative for fuscus. Note that it is not too dissimilar to the previous bird from Finland, although this individual shows more pronounced markings in the wing coverts. Possibly this is what some birds from mixed pairs intermedius x fuscus look like?
