Iceland Gull (Larus glaucoides)
Capercaillie (Tetrao urogallus)
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.

CCVery large and heavy bird with heavy bill and rounded tail with straight outer tail-feathers. Both sexes lack wing-bars. Males much bigger than females. Plumage mostly black with brown wings and yellowish bill. Females mottled brown with brick-red breast, throat and chin. Lower back greyish, contrasting with rufous, heavily barred, tail.
Sound:Display-sounds from male unmistakable. Four phased song: First a slow introductory, double-tapping phase which suddenly bursts into an accelerating crescendo followed by a distinct pop. Then closing with grinding and hissing sounds. Female calls with a deep nasal "kok kok".
