As wind farming becomes more prevalent, a new study from UNBC shows what these projects have on area birds.
Professor of Biology Ken Otter has been looking at bird migration patterns to see if windmills impact them.
He says they looked at bird behaviour before and after the wind farms were constructed.
Otter says this suggests birds are seeing the turbines and adjusting their flight paths.
He says birds that fly at night are more likely to fly above the turbines, so there impact is also minimal.
