CCAll white wingtips like Iceland Gull. The following characters applies to all ages: Told apart from Iceland Gull by angular head profile, proportionally shorter wings and long, heavy bill. Bill longer than half the length of head, and shows prominent hook. Primaries extends just about past tail in sitting birds, and the whole rear of the bird seem heavier. Eye smaller than in Iceland Gull, with a stern expression. Comparison with nearby Herring Gulls fruitful. Iceland Gull often smaller than Herring Gull, and less heavy, while Glaucous Gull usually larger. Impression reinforced by Iceland's agile maneuvering.
Sound:Like Herring Gull.
