Description

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. 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. Measurements: * Length: 6.3-7.9 in (16-20 cm) * Weight: 1.9-2.5 oz (55-70 g) * Wingspan: 19 in (48.2 cm)
