This strictly coastal plover nests on a bare scrape on sandy beaches or sandbars.

This is a small plover at 17–20cm. The adult's upper parts are mainly dark grey, with a short white wing bar and white tail sides. The underparts are white except for a breast band, and the legs are pink, brighter when breeding. The dark bill is large and heavy for a plover of this size. The call is a high weak whistle.

The breeding male has a black breast band, lores and forecrown, and a rufous mask. Females and non-breeding males have a similar plumage, but the black of the breeding male is replaced by brown or rufous. Non-breeders have a greyer tint to the head and breast band.
Immature birds are similar to the female, but the breast band is often incomplete.
