Habitat Breeds on tundra; chiefly coastal mudflats on migration.

Discussion Except for a small area on the Arctic coast of Alaska, where it is a rarity, this Old World species breeds solely in northern Siberia. During spring migration the adults are in their bright chestnut breeding plumage and, with their curved bills and white rumps, are easily distinguished in the field from their usual associates, the Red Knots and Dunlins. However, on fall migration in their dull winter plumage they are much more difficult to spot among the hordes of other shorebirds.
