Beobachtungsdetails

Adult, present the whole time. Difficult to pick out among the Herring Gulls but very limited black in wingtips conspicuous even at rest, only faint head streaking, proportionally large head and bill, thick neck, photos added. Two photos of it standing on the ice are actually from the following day when it was seen closer at Barton Cove.
