'Western' Herring Gull
Larus argentatus argenteus

Unless individual birds have been definitively identified as 'Scandinavian' or other races within the Herring Gull complex (based on plumage and/or location), I have defaulted to lumping them all here. If you find an image that you believe should be re-assigned, I'd be very grateful to learn of your thoughts. Thanks!
