A family of trumpeter swans and a cygnet swims in blue waters of Tangle Lakes near Alaska's Denali National Park. Trumpeter Swans forage in shallow water, reaching under the surface to eat aquatic vegetation. Although Trumpeter Swans have been dubbed “a classic conservation success” and numbers have increased, human threats affect the population. The swans are extremely sensitive to human disturbance at their breeding sites and will abandon nests and cygnets if disturbed.
