Arctic Tern (Sterna paradisaea)
White-fronted Goose (Anser albifrons)
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.

CCOrange legs and all pink bill without markings. Adults with white bill base and black markings on belly. Juveniles lacking those characters. Body shape and head more angular than other geese. Could be confused with Lesser White-fronted Goose, but Lesser have an obvious yellow eye-ring, and much more white around bill base. Wings more narrow than other grey geese.
Sound:Similar to Bean- and Greylag Goose, but higher pitched, more musical, often disyllabic and with a laughing quality. Far from as high pitched as Lesser White-fronted Goose.
