Appearance:

Summer plumage: Warm, rufous brown below like Knot, but much smaller. Bill curved and much longer, and appearance more long-legged. Winter and juvenile plumage grey above and pale below. Differs from Dunlin in slightly longer legs and bill, more pronounced supercilium, no black patches on belly (some rufous summer feathers may show when moulting) and more upright stance. Juveniles with buff-pinkish tone to breast, and scaly upperparts. Always distinct in all plumages when flying, due to bright white and crescent-shaped rump-patch.

Sound:

Flight call a soft, ringing and rolling "krrrrrt, with variations. Lacks the hoarse, nasal quality of similar call by Dunlin.

Appearance:

All 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.
