Geographic range.—Breeds in northwestern and northcentral North America. Winters south to West Indies, Panamá, and west to Hawaiian Islands. In Micronesia: Marshall Islands—Jaluit.
Remarks.—Reichenow (1901:17) and Schnee (1901:131) reported that flocks of ducks belonging to this and other American species were observed in the Marshall Islands in October, 1899, and May, 1900. This species may winter in the Hawaiian Islands, according to Peters (1931:167). If so it is not surprising that occasional visitors reach eastern Micronesia.
