_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.
