Ruddy Turnstone foraging on beach
5 June 2015
Ruddy Turnstones are a familiar, medium-sized shorebird of beaches on both coasts. In breeding plumage, their bold, contrasting plumage is almost cartoonish, and this species also feeds very actively, flipping over rocks and shells with its bill to search for invertebrates as it marches along the shoreline.
