Least Sandpiper

Least Sandpipers are the smallest of the small sandpipers known as “peeps”—not much bigger than a sparrow. They have distinctive yellow-green legs and a high-pitched creep call.

Look for them on edges of mudflats or marshes, where they walk with a hunched posture and probe for little crustaceans, insects, and other invertebrates.

This common but declining shorebird migrates thousands of miles between its arctic breeding grounds and wintering grounds as far south as Chile and Brazil. Cornell All About Birds
