Spotted Sandpiper - Chevalier grivelé par Thibaut Mathieu
Most sandpipers nest only in the far north, but the little "Spotty" is common in summer over much of North America. As it walks on the shores of streams, ponds, and marshes, it bobs the rear half of its body up and down in an odd teetering motion. When startled, it skims away low over the water, with rapid bursts of shallow wingbeats and short, stiff-winged glides. Even where it is common, it is seldom seen in flocks.
