MILWAUKEE (AP) - Wisconsin’s trumpeter swan population is soaring, and the Department of Natural Resources estimates that nearly 4,700 now grace the skies of the state.
The Milwaukee Journal Sentinel reports (https://bit.ly/1UXiKyi ) the new estimate is up sharply from about 670 birds in 2010.
Biologists began reintroducing trumpeter swans in the late 1980s. The birds were essentially hunted out of existence in 1800s. The last recorded sighting in Wisconsin before the reintroduction had been in Oconto County in 1937. The DNR removed the swans from the endangered list in 2009.
Sumner Matteson, an avian ecologist with the Wisconsin DNR, says it’s been an unprecedented success across the region. Neighboring Minnesota has around 17,000 of the birds.
Twenty-five Wisconsin counties have significant trumpeter swan populations, including a core area of northwest Wisconsin.
