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.

Appearance:

Medium sized eagle with long, evenly broad wings and relatively short tail. Easily confused with Lesser Spotted Eagle, Clanga pomarina. Flight feathers usually paler than the dark coverts, and head and body same colour as wings. Only diffuse pale patch at base of primaries on upper wing (marked in C. pomarina). Pale base of primaries shows as "comma", but usually lacks pale base of under primary coverts, contrary to C. pomarina. Broader wings than C. pomarina, and the squarish wing-shape, short neck and tail recalls White-tailed Eagle (H. albicilla). U-shaped white patch at base of tail. Immature birds even darker than adults, and show white spots along upper wing coverts in two narrow bands. Very long "fingers" overall, and elongated 7th primary. Soars and glides on horizontal wings with drooping hand (as C. pomarina). Bill obviously heavier than C. pomarina, and yellow base and gular region stands out. Round nostrils.

Sound:

Vocal at breeding ground, and when courting. Short, barking, high-pitched whistles, not unlike a small dog. Slightly lower pitched than C. pomarina and with a fuller tone, but very similar.
