State wildlife officials said an eagle's nest near the Fox River around Burlington is the first confirmed in the area in over a century.
Ron Eckstein is retired from the state Department of Natural Resources. The former wildlife biologist told the Kenosha News the DNR hadn't been aware of any eagle nest in Kenosha or Racine counties since at least the 19th century.
He said eagle nesting grounds are more common in northern Wisconsin.
The nest is on private property in southwest Racine County. DNR wildlife technician Seth Fisher flew over the nest this week. He didn't see eggs but saw an eagle hunkering down in a way that suggested it was incubating an egg.
Eagles are considered a species of "special concern," which means the DNR monitors their status.
