Breeding populations restricted to Hall and St. Matthew islands in the Bering Sea. Breeds on vegetated and rocky tundra, apparently most common on coastal lowlands of breeding islands (Lyon and Montgomerie 1995). Nests in crevices in rocks on open rocky ground, on beaches (in old hollow drift logs), and on shores of tundra pools; few nests ever observed (Terres 1980, AOU 1983). Non-breeding habitat is open tundra and rocky or sandy areas, coastal marshes, and on fields or anywhere that exposed vegetation is present (AOU 1983; Lyon and Montgomerie 1995).
