  • 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.

  • Grazes on marine algae below the high-tide line, or eats shoots and digs up root bulbs with the bill. Also digs up or pries off mussels and barnacles from rocks or the sea floor.

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