Over 2500 Harlequin Ducks (Histrionicus histrionicus) have been marked with individually identifiable tarsal leg bands in the Pacific Northwest of North America. Two of these populations have been intensively studied near Vancouver, British Columbia over three winters (1994-1996). Intensive marking and surveys were done at these two sites (White Rock and Point Roberts, WA) to assess movement patterns and emigration of Harlequin Ducks.
