Great Skua (Stercorarius skua)
Red-billed Chough (Pyrrhocorax pyrrhocorax)
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".

CCAll black plumage, red legs and long, curved, red bill. Bill of juveniles yellowish-brown and shorter. Though never as pure yellow as in Alpine Chough, and more curved. Easily confused with Alpine Chough at a distance where both species occur, but note broader, more fingered wings, shorter and squarer tail with broader base and different calls. Flight extremely acrobatic.
Sound:Call: A rapidly descending "keeaaaw", sometimes resembling a coarse jackdaw. At other times a more mewing sound, with similar coarseness, or a sharper, descending "kieew". Easily distinguished from the thin, trilling, whistling sounds of Alpine Chough.
