Summer Range: Spotted Sandpipers breed across North America from Alaska to Newfoundland, southward to central California, southern Nebraska, and northern North Carolina. Migration timing and distances vary according to a bird’s sex and age; females leave the breeding sites before males. In spring older females arrive before males and younger females.
Winter Range: Spotted Sandpipers spend winters from the southern states to southern South America. Some birds spend the winter in the Hawaiian Islands. They’ll also be found along Pacific Coast northward to Puget Sound, wherever open water is present. Fall migration occurs in small flocks, mainly at night.
