Facts about Waterfowl
All Waterfowl are members of the Duck family. There are five categories of ducks: dabbling ducks, diving ducks, perching ducks, stiff tailed ducks and mergansers.
Fourteen kinds of dabbling ducks are found in North America. They include the mallard, teal and pintail. The most common type of perching duck is the wood duck. The most common diving ducks in North America are the canvasback, scaup, eider and ring neck ducks.
Geese are smaller than swans but larger than ducks. Eight different species of geese are found in North American territories. The most common are the Canada goose, snow goose and white fronted goose. Canadas, with eleven sub-species, are the most common of all in this area.
Swans have an amazing 6-8 foot wing span. Four types of swans are found in North America: the mute, trumpeter, tundra and whooper.
Herons (herons, bitterns and egrets) are long legged, long necked wading birds. Herons are usually seen on the edges of water "fishing". The great blue heron has a wingspread of up to six feet and reaches four feet in height.
Loons are strong divers, able to stay under water for up to a full minute searching for food. There are four kinds of loons found in North America: the Arctic, yellow-billed, red-throated and common loons. They are large birds, up to a little over 3 foot long with wingspans to 58 inches, though are usually seen at great distances. Because of the position of their legs, loons are not able to walk on land, or take off from land. They need great distances to take off on water, but are strong fliers once they are airborne.
