Appearance:

Bulky, golden-brown heron with thick neck and short legs. Largely unmistakable but skulky behaviour makes it difficult to observe, as it generally forages hidden in reed-beds. Plumage mottled above, with coarse stripes below. Primaries and most secondaries with dark barring, in contrast to paler coverts. May recall Eagle Owl in flight with broad, rounded wings and retracted neck, but wings are bowed and legs trail behind tail. Crown and moustache stripe black in adult and brown in immature birds. Betrays its presence by it's far reaching song.

Sound:

Flight call a deep croaking "graat". Song unmistakable and far reaching (up to 5 km). Pitch very deep, with timbre similar to blowing on a big empty bottle. At close range an "inbreath" is also audible (1-3 dampened, higher pitched introductory notes).

Song (note; recording not audible on small mobile devices):

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.
