Appearance:

White secondaries the most striking feature in all plumages. Generally heavy built with large bill, heavy head, thick neck and short tail. Male: black with white crescent below eye and partly orange bill. Female sooty black with variable light patches at lore and cheek. Flaps it's wings with a raised head when on water. Dives without jumping and with wings slightly open. Swimming birds may not always show white secondaries. Tends to form less dense flocks than Common Scoter, often with birds in single file.

Sound:

Seldom heard. Calls: Short accented "tup tup tup" and a shivering "gahhahahaha".

Appearance:

Large and heavy skua with broad wings and short tail. The white patches at base of primaries are more striking than in the other skuas, and are visible both on upper and underside of wings. Size comparable to Herring Gull, but build more compact. Seemingly black at a distance, but white wing-patches usually visible. Confusion with juvenile Pomarine Skua possible, but body is heavier (not just the chest), wings rounder, bill longer, neck thicker and tail shorter.

Sound:

Heard mostly at breeding ground. Short, and dry "kek", when agitated. Also a nasal, slightly mewing "kew".

Alarm call:
