Arctic Tern (Sterna paradisaea)
Jack Snipe (Lymnocryptes minimus)
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.

CCNotably smaller, darker and with shorter bill than Common Snipe. Two prominent yellowish back-stripes. Dark wedge-shaped tail, and slightly rounded wings. Lacks median crown-stripe. Flanks spotted, not barred. Diagnostic behaviour: Usually flushed only at close range. Takes off silently, then quickly lands nearby. Whole body bounces rhythmically when feeding.
Sound:May occasionally give a harsh, nasal and rolling "reearrr" when flushed, but is usually silent. Display call a peculiar, cyclic and rhythmic sound performed in flight. Recalling a galloping horse in the distance. "Galloping" interspersed with cyclic, whistling, hissing sounds. Hard to locate when displaying. Seems both close and distant at the same time.
