Director of Science Nature Conservancy in Wyoming, Holly Copeland remarked, “Over a half million birds and about a million bats, a study in 2013 by Smallwood, et al showed. And if you run those numbers out for Wyoming there are about 5000 grassland birds we would be losing every year…there was a paper that showed 20 eagles and in addition to that Duke Energy reported 52 eagles as well.”

Of Wyoming's 15 resident bat species, three of them are most susceptible to the deadly effects of wind turbines: the hoary bat, the silver-haired bat and the eastern red bat. They are Wyoming's only tree-roosting bats, said Douglas Keinath, senior zoologist with the Wyoming Natural Diversity Database.
Miles away, wind turbines sat motionless in the windless night. Their spinning blades can be deadly to bats, bursting capillaries in their lungs before the blades hit their tiny bodies. Three Wyoming bats are particularly susceptible when they migrate from summer to winter ranges. Keinath and Abernethy were looking for bats to tell them which, if any, species called the area home.
