The Iowa Department of Natural Resources (DNR) will release 14 trumpeter swans at three locations in southwest Iowa as part of the effort to create a self-sustaining population of swans south of Interstate 80. All releases will occur rain or shine.
These releases are part of the Iowa DNR’s statewide effort to restore trumpeter swans to Iowa that began in 1993. Trumpeter swans were once common in Iowa, but were gone from the state by the late 1880s. By the early 1930s, only 69 trumpeter swans remained in the lower 48 states.
It takes six years, on average, before trumpeter swans successfully nest. Last year, Iowa was home to 54 pairs of nesting trumpeter swans; however, only two of those nesting pairs were south of I-80. Dave Hoffman, wildlife research technician with the Iowa DNR, said the goal is to raise that number to eight, which would likely create a self-sustaining population.
“We are hopeful to get them nesting here in a year or two,” Hoffman said. “We had swans displaying some territorial signs at Lake Icaria, which is encouraging.”
As the largest North American waterfowl, these all-white birds can weigh up to 32 pounds and have an 8-foot wingspan. The trumpeter swans being released are young and flightless and will imprint on the area where they learn to fly, returning each year as open water is available. The swans were donated to the project from zoos in Cleveland, Kansas City, Green Bay, Wis., Oklahoma City, Bronx, Anchorage, Alaska and Maryland.
Each event includes a swan and wetland presentation, an opportunity to touch and view the swans up close, and a photo opportunity with the kids. Staff from the Kansas City Zoo will be on hand offering educational activities, and filmmaker Steve Harryman may be at these releases collecting footage for an upcoming documentary “Return of the Trumpeter Swans, in partnership with the Trumpeter Swan Society.
