Appearance:

Male with shiny black upperparts and pure white underparts. Female grey-brown with pale underparts. Both sexes with broad white edges to tertials and greater coverts, forming a broad white patch (largest in males). Fairly compact body compared to Spotted Flycatcher, with shorter tail and bill. Easily confused with Collared- and Semicollared Flycatcher where these occur. Both sexes differs from Semicollared in no white edges to end of tail and less white at base. Distinguished from Collared in white patch beneath alula being narrow and not reaching edge of wing (both sexes), white base of tail (black in Collared males) and no collar (males).

Sound:

Alarm call a sharp, energetic "wit", often in combination with a short "tic"; "whit-tic". Song a pleasant, tuneful, simple but varied phrase. Typically starts with disyllabic notes being repeated 3-5 times, diminishing in pitch and intensity like an echo of the first two syllables. Occasionally throws in a quick diagnostic ascending scale excercise. Clear notes and well defined pauses between phrases.

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.
