The British wading bird Sanderling (10 letters) is a small shorebird that breeds in the Arctic tundra and migrates to coastal areas in the winter. It has a distinctive black and white striped pattern on its wings and back, and its legs are usually grey. Sanderlings feed on small invertebrates such as insects, worms, and crustaceans, which they find in the sand or mudflats. They are often seen running along the shoreline in large flocks, chasing the waves as they recede.
