Appearance:

Very large tern, with deep, dagger-like, blood-red bill with dark tip. Large, black cap reaching well below the eyes. Grey upperparts and white underparts. Rather short tail. Outer primaries distinctly darker than the rest of upperwing, and outer underwing almost black. Unmistakable from the size alone, and leaves a gull-like impression, lacking the elegance of smaller terns. Immatures with paler bill and white forehead (as in adult winter), and markedly speckled back. Hovers and dives. Often rests on the surface, feeding like a gull.

Sound:

Easily recognized by its very harsh calls. Sometimes likened to the sound of a plate of steel being dragged across a concrete floor. Similar in harshness to Grey Heron, but more drawn, with an accented middle; "Kraaeeet", or with a double syllable start "ka-ha-kraaaeet". Immature birds begs with a penetrating, sharp whistle.

Appearance:

Large Tringa with upcurved bill. The mainly white and pale grey plumage (and head) gives it a pale appearance. Upper parts speckled in black in summer plumage. Upper side of wings rather dark, back lighter grey with conspicuous long white wedge. Tail white, with diffuse grey barring. Back of juveniles with v-shaped scales/fringes. Legs greenish to grey-green. Wing beats quite deep and sometimes with "slow motion" like quality.

Sound:

Most heard is a characteristic, trisyllabic "tew-tew-tew" (sometimes two or four syllables). Can resemble redshank, but pitch more stable, and not falling notably. Each syllable is clearly separated and equally emphasized. Song a clear disyllabic "cloo-eeee", repeated in cycles but each phrase clearly separated. At close range a short creaky sound is audible (between each phrase). Redshank may sing in a slightly similar way, but in continuous, linked phrases.
