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. |
