Spotted Redshank (Tringa erythropus)
Roseate Tern (Sterna dougallii)
Unmistakable 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".

Differs from Common and Arctic Tern by; noticably shorter wings, longer streamers, much paler grey upperparts, pure white underparts (faint rosy wash not very conspicuous), black bill (red base in breeding birds), dark outer primaries and no dark edge to inner primaries. Amount of red in bill increases as breeding season progresses, but also varies geographically. Wingbeats shallower and much quicker than in Common and Arctic Tern. Fishes with characteristic diagonal dives. Despite the long streamers, the birds appear short-tailed in flight, but head and bill are long and slender. The pale plumage, dark bill and giss recalls a small Sandwich Tern. Adult winter plumage with all dark bill and white forehead. Juveniles resembles juvenile Sandwich Terns, with more complete dark cap than Arctic and Common, and much more contrasting markings on back (especially to wings).
Sound:Extremely harsh calls. Like mix of Caspian and Arctic Tern. Very hard and raspy "kreeeet", harder and higher pitched than Caspian Tern, but equally harsh. Other calls include more Arctic/Common tern-like short "kek", and similar.
