Winter: mostly pale grey upperside, white underside with whitish breast area. Semipalmated Sandpiper has darker ear-coverts and upper breast
Juvenile: rufous on upper scapulars producing a contrasting V on the back, pale breast and side + underside of head.
Distribution
Breeds in eastern Siberia and Alaska. Migrates on both coasts of North America, far more common on the west coast where 4 million can be found in one area. Winters in South America.
Taxonomy

Habitat
Tundra and mudflats.
Behaviour
They nest in scrapes on the ground usually under some vegetation. The male makes several scrapes; the female selects one and lays 4 eggs. Both parents incubate and care for the young. Sometimes the female deserts her mate and brood prior to the offspring fledging.
