Diet and Foraging


Crested Duck feeds by dabbling and up-ending. They sieve though mud, silt or gravel although they also come ashore to forage or feed offshore in kelp beds. On the Falkland Islands they are mainly carnivorous, feeding on marine isopods and amphipods, invertebrate larvae and tiny clams (Weller 1972). Two L. s. alticola from Lake Junín, Perú are reported to have fed mostly on vegetable matter (Phillips 1922–1926).
