Swans(Subfamily Cygninae)Waterfowl (Order Anseriformes, Family Anatidae) in North America are divided into seven subfamilies:
Swans: heavy, white, long-necked birds of lake and river shores. They dip head and neck into the water to feed on bottom vegetation. They also browse on shore grasses. There is no black on the wing tips. Sexes are similar. Immatures are grayish brown above, white below. Swans have a deep, ponderous flight, with neck extended. They fly in V-formation or in lines. The only member of this subfamily which will likely be seen in Northern
Utah is the Whistling Swan (Olor columbianus).
