What the Sanderling sounds like

The Sanderling is a small, energetic sandpiper famous for its habit of chasing waves up and down sandy beaches. In non-breeding plumage it looks almost snow-white, earning its Latin name alba. During the brief Arctic summer it molts into a warm rusty plumage for nesting on the high tundra.
