Arctic Tern (Sterna paradisaea)
Spotted Redshank (Tringa erythropus)
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.

CCUnmistakable in breeding plumage, with all dark/blackish body unique among Tringas. Most birds seen in Europe will probably be in winter- or juvenile plumage, and can then be mistaken for Redshanks. Spotted Redshanks are slimmer, longer legged and more elegant than Redshanks. The supercilium is much more prominent, the bill is slimmer and longer. Most diagnostic is the lack of white wing-bars, and the white sigar-shaped patch on the back. The barring in juveniles reaches from the belly and all the way back to the vent. Often feeds in deeper water than Redshanks, even by swimming and upending.
Sound:Flight call loud and diagnostic, and is often the first sign of the species' presence; a sharp and short, disyllabic "koo-eett", with the first syllable falling in pitch and the second rising sharply. Display call a squeaky, but melodic "krroo-lee-ooo" repeated in cycles. Alarm call a falcon-like "ke-ke-ke-ke".
