The North American Trumpeter Swan – at Slimbridge WWT
“Trumpeter Swans once nested over most of North America, but disappeared rapidly as civilization advanced westward; by the 1930s, fewer than 100 remained south of Canada. With protection from hunting and disturbance, populations have rebounded in parts of the northwest. More recent efforts have focused on reintroducing the species to areas thought to be part of the former breeding range, including Minnesota, Wisconsin, Michigan, Ohio, and Ontario”

Largest of the native waterfowl in North America, and one of the heaviest flying birds, the Trumpeter Swan was almost driven to extinction early in the 20th century. Its healthy comeback is considered a success story for conservationists. Ordinarily the Trumpeter is quite sensitive to human disturbance; in protected areas, such as some parks and refuges, it may become accustomed to humans and allow close approach.
