Turnstone (Arenaria interpres)
A mainly coastal bird that turns over stones or moves seaweed to find insects. It breeds mainly around the Arctic coasts and migrates to other rocky coasts even as far as south Africa. They are ground nesting laying 4 eggs which hatch after 22 days.
These two pictures were taken on the Norfolk broads and coast of the Orkney Islands. The photograph in Norfolk was taken with the camera on the ground using a zig view system to be able to see into the viewfinder.
