- Color Pattern
Adults are blue-gray overall, with stark black-and-white edging to the feathers that creates a scaly appearance. They have a distinctive black throat and white head and back of neck; a pink-and-lavender bill; and bright orange legs and feet. Juveniles are similar but with a dark bill and with sooty patches on the white head and neck.

Nests in low tundra grasslands near edges of rivers and sloughs. Forages in tidal habitats such as mudflats, lagoons, rocky shorelines, and marshes.
