What the Least Sandpiper sounds like
The Least Sandpiper is the tiniest shorebird in the world—a sparrow-sized ‘peep’ that scurries mouse-like across mudflats and marsh edges. Warm brown upperparts, a clean white belly, a slim slightly decurved bill, and distinctive yellow-green legs set it apart from its close cousins.
