The story of the trumpeter swan in Minnesota has been widely considered one of North America’s most dramatic and successful wildlife restoration achievements. Once completely eradicated from the state, these iconic native birds have made a massive comeback.
Trumpeter swans are North America’s largest native waterfowl species. Many even weigh over 30 pounds. Before European settlement, they were common throughout the state. From the 17th to early 19th centuries, the birds were over hunted for their mat, skin, and feathers. People used them mainly as quill pens, and they were popular in fashion. The loss of wetland habitat further increased the pressure. By the end of the late 1800s, the trumpeter swan had completely disappeared from Minnesota. The last documented wild breeding records date back to the 1880s. By the 1930s, only 69 individuals remained alive in the entire lower 48 states. These remaining birds were centered around Red Rock Lakes in Montana, according to the Minnesota Zoo and the Minnesota Department of Natural Resources.
Minnesota’s modern swan population exists entirely because of a multi-decade restoration effort. In 1966, the Three Rivers Park District began breeding captive swans obtained from Montana. Independent releases struggled but laid the groundwork for future programs.
The Minnesota Department of Natural Resources took on swan restoration as a flagship project. It used funds from the DNR’s Nongame wildlife program. To diversify the genetic stock of the swans, the DNR, Minnesota Zoo, and Carlos Avery Wildlife Management Area flew to Alaska in the late 1980s to collect wild eggs and then hatch them and raise the birds in a protected environment.
Beginning in 1987, hundreds of sub-adult swans were released across safe wetland habitats in the state, including in Itasca and St. Louis Counties.
Since then, the population has grown from roughly 2,000 birds in the early 2000s to over 51,000 individuals now. The species is now widely distributed across the state, with most of them taking up residence in the east-central, north-central, and northwest regions.
Unlike a lot of waterfowl seen in Minnesota, Trumpeter swans don’t migrate vast distances. During winter, they gather at open-water sources. These include warm-water discharges from power plants along state rivers and lakes.
Despite the impressive comeback, trumpeter swans are still classified as a Minnesota Special Concern Species, and as such it’s illegal to hunt them.
The flock of trumpeter swans that have taken up residence on Silver Lake in Virginia this week is attracting people to the lake shore to view the impressive birds in person, even if many don’t realize the unlikely journey that brought them here.
