Waterfowl (Anatidae) is a very diverse family of birds that includes swans, geese and ducks.
They can be found on every continent except Antarctica and inhabit a variety of habitats including the high Arctic, the tropics and even the ocean.
They may be some of the most recognizable birds, as many species are commonly seen in city parks and on freshwater beaches.
Throughout North America, the most common waterfowl in cities and suburbs are Mallards (Anas platyrhynchos) and Canada Geese (Branta canadensis). Both species are highly adaptable and often gather in large numbers in city parks and on freshwater beaches.
