Calidris minutilla

The Least Sandpiper is the smallest shorebird in the world and has distinctive yellow-green legs. It has a short, slightly downcurved bill and brown upperparts. The species feeds on small invertebrates at the upper, drier edges of mudflats and marshes. It breeds in northern bogs and tundra and migrates to the southern United States and Latin America. Females often leave before the young can fly, while males complete parental care.
