Arctic Tern (Sterna paradisaea)
Ringed Plover (Charadrius hiaticula)
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.

CCMarked black breast-band and mask. Olive-brown upperparts and white underparts. Easily confused with Little Ringed Plover (especially juveniles). Diagnostic characters in adults are; striking white wing-bars (only faint in Little Ringed Plover), orange base of bill and legs, and no yellow eye-ring. Juveniles also show characteristic wing-bars, white supercilium extends behind the eye, lower part of "mask" is rounded and bill is stouter. Tertials do not cover tips of primaries.
Sound:Usually heard before seen. Contact call a short, soft "koo-eep", with the emphasised second part higher and rising in pitch. Song a cyclic repetition of the contact call. Sometimes with a shortened phrases and a more creaking timbre.
