The Harlequin Duck is a strikingly patterned little duck. Population in eastern North America has declined substantially over the last century. (Eastern population) breeds on inland rivers and streams from northern New Brunswick north to Nunavut, and winters in coastal areas from Newfoundland, south to Maryland, as well as southwest Greenland. Breeding habitat includes fast flowing river systems that may vary in width across the species range. In northern Labrador narrower, warmer and less acidic rivers are preferred (Rodway 1998). Multiple factors may impact river selection including acidity, physical features, food availability (Rodway 1998), and predator distribution (Heath 2001). Wintering habitat consists of rocky coastline, exposed headlands, and subtidal ledges (see Robertson and Goudie 1999). Harlequin Ducks are also regularly associated with offshore islands.
