Harlequin duck surveys in the central eastern slopes of Alberta, spring 1998 / Paul Gregoire, Jeff Kneteman, Jim Allen. : CW69-5/329E-PDF
"In response to a general lack of knowledge on the abundance and distribution of the Harlequin Duck within Alberta, the Canadian Wildlife Service in cooperation with Alberta Environment undertook surveys of the eastern slopes of Alberta. Helicopters provided an effective and efficient means to survey for Harlequin Ducks. High concentrations of Harlequin Ducks were observed on the Mcleod, Sulphur and Berland Rivers, with smaller concentrations on the Muskeg and Wapiabi watercourses. Few to no Harlequin Ducks were observed on many streams located south of the Brazeau River. Harlequin concentrations on the Mcleod, Berland and Wapiabi streams were not within protected areas. Harlequin Ducks appear to be uncommon and demonstrate a patchy and clumped distribution along their range within the eastern slopes of Alberta"--Abstract, p. i.
