    Common Merganser Identification

    The Four Keys to ID

    • Size & Shape

      These are large, long-bodied ducks with thin, pointed wings. Their bills are straight and narrow, unlike the wide, flat bill of a “typical” duck. Females have shaggy crests on the backs of their heads.

      Relative Size

      Smaller than a Canada Goose; slightly larger than a Mallard.
