Avocet (Recurvirostra avosetta)
Great Skua (Stercorarius skua)
An elegant, long-legged, black and white wader with a long, upcurved bill. Plumage mainly white, with black wing-tips, coverts, crown and hind-neck. Pretty unmistakable. Confusion with Crab Plover or Juvenile Shelduck possible at very long range. Flight pattern even and mostly without glides.
Sound:Not very vocal away from breeding ground. Most common contact call a soft, short "kluitt" reminiscent of Ringed Plover, but harder and less varied. Also sometimes followed by repeated chattering: "kluitt-trt-trt-trt-trt-trt-trt".

CCLarge 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".
