The Greater Scaup is a diving duck and is closely related to the Lesser Scaup though larger. It spends the summer months breeding in Alaska, Northern Canada, Siberia and the Northmost parts of Europe.

Their main threat is loss of habitat due to human intervention and their numbers have steadily decreased over the years. They are currently classed as Least Concern.
