CHEYENNE, Wyo. (AP) — The developers of what could become the largest wind energy project in the U.S. say the federal government has vastly overestimated how many eagles will be killed at the site.

They say they plan to take measures that will result in fewer deaths.

The Power Company of Wyoming is preparing to apply for a U.S. Fish and Wildlife Service eagle take permit for the first phase of the planned Chokecherry/Sierra Madre wind farm south of Rawlins. Fish and Wildlife expects the application process to take about a year.

Company officials question a U.S. Bureau of Land Management estimate that the 1,000 wind turbines will kill 46-64 eagles a year. They say they're discussing the issue with Fish and Wildlife as the agency prepares to develop its own eagle mortality estimate.
