沙丘鶴 Antigone canadensis

Large, long-legged bird shaped much like a heron. Gray body, sometimes with intense rusty staining. Adults have red crown. Often in large flocks at migration and wintering concentration points. Favors marshes and agricultural fields where they eat primarily grains. In flight, neck is outstretched, unlike herons with tucked necks. Snappy wingbeats. Listen for far-carrying bugling call.
