DESCRIPTION 



Adult Male: Plumage almost exactly like that of the Greater Scaup except that in a shaded light 

 the reflections on the feathers of the head and neck are purple instead of green. The black markings 

 on the scapulars are somewhat coarser and broader. The feathers of the sides and flanks are browner 

 and more or less vermiculated. The primaries are more nearly uniform in color, without distinctly 

 pale areas.
