Trumpeter Swans are our biggest native
waterfowl, stretching to 6 feet in length and weighing more than 25 pounds. Despite their size,
they are as elegant as any swan, with a graceful neck and snowy-white plumage. Getting airborne
requires a lumbering takeoff and running hard across the surface, they almost sound like galloping horses as they
generate speed for takeoff. Trumpeter swans are native to Iowa. When
Europeans began to settle Iowa in the 1850s, trumpeter swans nested across Iowa, but by the 1880s
they were gone—the last recorded nest was in 1883. Iowa’s DNR began to reestablish the
birds in Iowa in the 1990s which helped the species recover by the early 2000s. Trumpeter
Swans breed in open habitats near shallow water bodies and take an unusual approach to incubation: they warm the eggs
by covering them with their webbed feet. A pair has nested at Jones Pond near Preparation Canyon
in Monona County for several years.
