Arctic Tern (Sterna paradisaea)
Dunlin (Calidris alpina)
Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.
Sound:Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.

CCOnly small wader in the region with a dark or spotted belly. Most common small wader in area, and an important reference species when identifying congeners. Bill quite long with slightly curved tip. Legs dark. Summer plumage with unmistakable large black patch on belly, and variable warm, rufous brown back. Juveniles and moulting adults usually shows at least some diagnostic dark spots on belly in contrast to white flanks. White V-shaped markings on back, but not as striking as in juvenile Little Stint. Only adults in winter plumage shows completely white underparts (and uniformly grey back).
Sound:Contact call a diagnostic, very nasal "trrreeet" . Given throughout the year and in many situations, including when being flushed. Song: A drawn out, nasal "tweeet", and ringing variations on the contact call in decrescendo. Low chattering heard from feeding birds.
