Oystercatcher (Haematopus ostralegus)
Common Tern (Sterna hirundo)
Unmistakable shorebird. Large wader with black and white plumage, striking orange-red, straight bill and red orbital ring. Legs pinkish in adults and grey in juveniles. Broad white wing-bars. Stocky build, with fairly short legs and broad chest. Flight pattern straight and level. Winter plumage with white half-collar on chin. Juveniles with browner tone to upperparts than adults, and black tip of bill.
Sound:Very vocal. Sharp, loud and far carrying, disyllabic or monosyllabic calls "ku-eek" or "kleek". Often works itself up into a crescendos of fast, piping calls, and then mellows out.

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.
