Forty years ago, just 83 eagle nests were counted in Michigan. Experts say they could top 700 this year.

Michigan, of course, has many forests and much water, which are good conditions for eagles. The U.S. Fish and Wildlife Service continues to check the effects of pesticide on the giant birds.

The Lansing State Journal reports that two eaglets were recently tagged at Muskegon State Park. They were weighed and measured, and wildlife handlers took blood and feather samples.

Wildlife biologist Matt Stuber believes many eagles spend the winter in Michigan. He says some go to Monroe, in southeastern Michigan, where warm water from a power plant support many fish, a perfect meal for an eagle.
