Steller's Eider (Polysticta stelleri)
Iceland Gull (Larus glaucoides)
Diagnostic, squarish head profile with flat crown, high bill base, steep forehead in all plumages. Male unmistakable with white and orange-buff underparts, white head with dark eye-patch, black collar and black back. Female mottled brown, but distinguished by head profile and blue wingbar with white edges. Identifiable at a distance by its habit of holding the tail raised clear of the water like a dabbling duck.
Sound:Male seldom heard. Display sound probably a clear whistle rising slightly and then falling in pitch, a bit like Golden Plover. Female more noisy with indistinct guttural sounds.

All white wingtips like Glaucous Gull. Told apart from latter by rounded head, longer wings and shorter, more slender bill. Bill shorter than half the length of head, and lacks prominent hook. Primaries extends well past tail in sitting birds, and the whole rear of the bird seem slimmer. Eye bigger than in Glaucous Gull, with a more "gentle" 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, but tone sharper.
