For an overview of the duck, goose and swan family of birds, see Anatidae.

These large fish-eaters have serrated edges to their bills to help them grip their prey. Along with the Smew and Hooded Merganser, they are therefore often known as "sawbills". Species are: Brazilian Merganser Mergus octosetaceus Auckland Island’s Merganser Mergus australis (extinct) Red-breasted Merganser Mergus serrator Common Merganser or Goosander Mergus merganser Chinese Merganser Mergus squamatus This article is from Wikipedia.
