Figure 1. Distribution of Greater Scaup in North America.

Dashed blue line shows eastern extent of occasional breeding in central Alaska. Blue stars show locations of isolated, persistent breeding populations outside of primary breeding range. Blue dots indicate isolated nest site or small, isolated breeding population of uncertain persistence. During winter, small numbers occur on inland rivers, lakes, and reservoirs north to the dashed orange line. This species also breeds in Europe and Asia. See text for details.
