The Red-breasted Merganser (Mergus serrator) is a ‘saw bill’ diving duck. The adult Red-breasted Merganser is 51–62 cm (20–24 in) long with a 70–86 cm (28–34 in) wingspan. It has a spiky crest and long thin red bill with serrated edges. The male has a dark head with a green sheen, a white neck with a rusty breast, a black back, and white underparts. Adult females have a rusty head and a grayish body. The juvenile is like the female, but lacks the white collar and has a smaller white wing patch. [Wikipedia]
