Appearance:

A small, active and quick wader, sharing traits of both Tringa and Calidris type. Most easily identified in the field by it's behaviour and sound. Most distinct plumage feature is the white wedge in front of the wings at the sides of the breast. Body is elongated and legs fairly short and greenish. Constantly bobs body and head. In flight the dark rump and white wing-bars are obvious. Often flickers its wings when flying low above water, especially just before landing.

Sound:

Very vocal with characteristic repertoire of very high-pitched calls. Often heard is a disyllabic call, drawn out and slightly rising in pitch in the second part. This is often repeated in a series of rising tones in a cyclic manner, with approx 5 tones in each cycle.
