Appearance:

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.

Appearance:

Adults differ from most other waders by bright red legs. Large white rectangular patches on secondaries conspicuous in flight in all plumages. Spotted redshanks in winter- or juvenile plumage lacks white wing bars, are more elegant with a more slender bill, and shows a stronger dark eyestripe and white supercilium. Juvenile Redshanks are unevenly, and sparsely spotted below from the legs to the vent, as opposed to the barring of juvenile Spotted Redshanks. Leg colour in juveniles often dull yellowish. Flanks evenly spotted. Winter plumage with brownish upperparts.

Sound:

Generally a noisy and loud bird, especially at breeding ground. Most heard is a characteristic "tew-hoo", or "tew-hoo-hoo" with first syllable accentuated. No gap between the syllables like Greenshank, and usually with a marked falling pitch. Song similar to Wood Sandpiper, but with three accented notes in each cycle, not two.
