Sex and age - specific distributions of sea ducks wintering in the Strait of Georgia, British Columbia : implications for the use of age ratios as an index of recruitment / S.A. Iverson ... [et al.].: CW69-5/459E-PDF
"Management of sea duck populations in North America has been hampered by a lack of effective population monitoring tools. In this study, we used sex and age ratios calculated from direct visual counts to assess the demographic structure of the nine most common sea duck species wintering in the Strait of Georgia, British Columbia: Black Scoters (Melanitta nigra), Surf Scoters (M. perspicillata), White-winged Scoters (M. fusca), Harlequin Ducks (Histrionicus histrionicus), Barrow’s Goldeneye (Bucephala islandica), Common Goldeneye (B. clangula), Bufflehead (B. albeola), Common Mergansers (Mergus merganser), and Red-breasted Mergansers (M. serrator)"--Abstract.
