Common Tern (Sterna hirundo)
Green Sandpiper (Tringa ochropus)
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.

CCA dark, often secretive, wader. Quite similar to Wood Sandpiper, but differs in dark underwings, only small white spots on back, defined border between speckled chest and white belly, broad dark markings on tail and a supercilium that does not reach behind eye. Leaves an overall much darker impression than Wood Sandpiper. Particularly in flight.
Sound:Totally different from Wood Sandpiper. Sharp, penetrating calls. Display call a high-pitched "kee-kleeoo-eet", continuously repeated with a wave-like motion in pitch. Other common calls have similar timbre and tone with different phrasing like; "klooeett -klee-klee-klee-klee-klee" and a rising pitch.
