A recent study of 183 DTE Energy wind turbines found that bird and bat deaths per megawatt is just above average compared to other wind parks in the Midwest.

The Service’s three-mile setback from Great Lakes shorelines is a recommendation based on areas along the shoreline identified as having the highest habitat value for migrating and nesting birds. Hicks said the agency cannot force developers to apply for permits, but killing an eagle and not having an incidental take permit can result in prosecution. The Service’s 2012 wind energy guidelines are voluntary for developers.
“If municipalities are going to go by avian studies that are funded by turbine developers, they’re not going to find mention of something such as this migration that has been documented since 1991. Right now, we are relying on numbers from the exact corporations that don’t want to find any dead birds, because any dead birds they find is subjected to prosecution and fines.”
Sometimes it's not easy being green. Proponents say Michigan is ideal for wind generation, a Green Power energy source that is pollution free and self renewing. But some worry that spinning wind turbine blades up to 85-feet long could be lethal scythes for migrating birds, especially if, as some predict, wind generation gathers steam in Michigan.
