The greater scaup (Aythya marila), just scaup in Europe or, colloquially, "bluebill" in North America, [3] is a mid-sized diving duck, larger than the closely related lesser scaup and tufted duck. It spends the summer months breeding in Iceland , east across Scandinavia , northern Russia and Siberia , Alaska , and northern Canada .
Lesser scaup are thought to comprise slightly less than nine-tenths of the scaup population of North America. In the 1970s, the lesser scaup population was estimated at 6.9 million birds on average; in the 1990s it had declined to about half that number, and by the late 2000s it is estimated at 3 million individuals or less.
