CCMarked black breast-band and mask. Olive-brown upperparts and white underparts. Easily confused with Little Ringed Plover (especially juveniles). Diagnostic characters in adults are; striking white wing-bars (only faint in Little Ringed Plover), orange base of bill and legs, and no yellow eye-ring. Juveniles also show characteristic wing-bars, white supercilium extends behind the eye, lower part of "mask" is rounded and bill is stouter. Tertials do not cover tips of primaries.
Sound:Usually heard before seen. Contact call a short, soft "koo-eep", with the emphasised second part higher and rising in pitch. Song a cyclic repetition of the contact call. Sometimes with a shortened phrases and a more creaking timbre.
