This rangy rock-loving species is one of the few shorebirds with heavily barred underparts. It can be readily separated from most other rock-pipers by its longer bill and long folded wings. All ages have mostly black bill with gray at the base of the lower mandible, yellowish to yellow-green legs, and a thin, broken white eye ring. Alternate Adult: Plain gray upperparts, with dark lores and a whitish supercilium most prominent in front of the eye. The underparts are white with extensive dark barring. Basic Adult: Plain gray overall, fading to white on the belly. Dark lores and short white supercilium still apparent. Juvenile: Like Basic Adult, but with pale edges on wing coverts. Flies with deep, powerful, and sometimes irregular wingbeats that suggest the flight style of a yellowlegs.
Length: 26 (cm) Wingspan: 50 (cm)
Call is a rapid series of sharp notes: ti-ti-ti-ti-ti, sometimes paired: ti-di, ti-di, ti-di.
Nests on tundra near gravelly streams. On migration and in winter, usually found on rocky coasts.
Often bobs tail while feeding. Usually seen singly or in small groups of other rock-pipers.
Probes rocky areas for marine invertebrates.
