Little Auk (Alle alle)
Common Tern (Sterna hirundo)
Small and compact auk. Bill short and blunt, tail and wings short. Scapular feathers with characteristic white brims. Differs from young Puffin by white "thighs", white throat and only faint neck collar (in winter). Often difficult to spot when swimming in waves, and more often seen when flying. Take-off from water surface easy and direct. Flight less constricted than larger auks, and changes direction frequently and with ease.
Sound:Voice higher pitched than other auks (except Black Guillemot). Trilling, rolling and chattering laughter "kreeee he he he he", or shorter, softer utterances; "ke ke" or "hup hup".

Differs 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.
