Little Ringed Plover (Charadrius dubius)
Arctic Tern (Sterna paradisaea)
Differs from Ringed Plover by bright yellow eyering (adults),only faint wing-bars, long tertials (covering the primaries) and slimmer more elongated body shape. Apart from the diagnostic eyering, adults show white band across crown, brown-grey legs (not orange) and dark bill. Juveniles also show only faint wing-bars, supercilium is faint, especially behind the eye, lower part of "mask" is pointed and bill is slimmer.
Sound:Quite different from Ringed Plover. Sharper sounding, lacking Ringed's soft tone. Often starts with a rolling "r". Common calls are a two syllable "krrll-uuit" with a rising pitch or just a sharp, rolling "krrri-krrri". Also a longer rolling "krree-looo" with pitch rising in first syllable and falling in the second.

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.
