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".

Appearance:

Huge bird of prey with almost white head, neck and ruff. Body buff and wing-coverts pale buff in marked contrast to dark flight-feathers (opposite of Black Vulture). Silhouette typical with small head and short tail. Wings with S-shaped trailing edge, and very long and widely separated primaries. Soars with wings raised in shallow V. Glides on bowed wings, with slightly folded and depressed primaries.

Sound:

Quite vocal for a vulture, but generally silent in flight. Various shrieking high notes, hissing, and harsh cackling sounds.
