Their breeding habitat is the northern tundra on Arctic islands in Canada and coastal areas in Greenland and northwestern Europe. They nest on the ground either elevated on rocks or in lower damp location. The males makes several scrapes; the female choose one and lays 3 or 4 eggs. The male takes the major responsibility for incubation and tends the chicks. The young feed themselves.
They are late migrants and move to rocky ice-free Atlantic coasts in winter. most go no further south than North Carolina and northern Portugal. They are fairly gregarious, forming small flocks, often with Ruddy Turnstones. This species is tame and approachable.
These birds forage on rocky coasts, picking up food by sight. They mainly eat insects and mollusks, also some plant material.
