Ruddy Turnstone (Arenaria interpres) in non-breeding plumage foraging on a mussel bed against a backdrop of multiple lens flares by the seashore of 'Le Pouldu' in the Finistère department, Brittany, France. Ruddy Turnstones often flip over stones and other objects to get at prey items hiding underneath; this behaviour is the origin of the name "turnstone". They also crack open their preys' shell by using their bill as a hammer, and then extract the animal inside through pecking and probing.
