Avocet (Recurvirostra avosetta)
Common Tern (Sterna hirundo)
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".

CCDiffers from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.
Sound:Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
