UNDATED (WSAU) The Wisconsin Department of Natural Resources reports three species of owls have been pushed south from Canada into this state this winter. A crash in rodent populations may be the cause. The northern hawk, the great gray and the boreal owls are normally rare sights in Wisconsin.
The drop in rodent numbers in Canadian forests has forced them to move. Some of the observations have been made in southern Wisconsin, including a great gray seen in Middleton, in Dane County. There have been some problems. Northern hawk owls have been hit by cars.
Experts say the drop in rodent populations in Canada is cyclical.
