Ruddy turnstone fact sheet

Arenaria interpres | Ruddy turnstone

The ruddy turnstone is a small and plump wading bird with short orange legs and checkered dorsal plumage. The chest and belly are white (with a distinctive black bib) and the black beak is short and wedge-shaped. In the non breeding season they are dull in colour, but during the breeding season the lighter plumage on their back becomes orange. In flight they have distinctive white wing stripes and black on the trailing edge of the wings. The Ruddy turnstone is a highly migratory bird that is found throughout northern Eurasia as well as North and South America. In the winter they spread to coastlines of almost the entire world. They are present on all islands of the Azores throughout the year and are mostly observed on pebble beaches coastal lagoons. In the winter we often see them in the marina Here they are usually seen running busily over the rocks, making them very difficult to photograph. This species is classified as a "common vagrant" in the Azores.
