A Wyoming conservation group filed a federal lawsuit this month against the U.S. Fish and Wildlife Service, arguing that the agency is illegally withholding records on bald and golden eagle deaths at three wind projects in southern Wyoming. [emphasis, links added]
Mike Lockhart, a biologist who worked for the Fish and Wildlife Service (FWS) for over 30 years, told Just the News that the data the federal government is withholding could help assess the true impacts of wind energy in Wyoming on eagle mortality.
“We have no real idea of how many birds are being killed. There [are] birds that I suspect are being killed that just disappear in the presence of the wind turbines. And I think the numbers are enormous compared to what we know right now,” Lockhart said.
Blocked as “Privileged and Confidential”
Earlier this year, the Albany County Conservancy, based in Laramie, Wyo., filed a request under the Freedom of Information Act, seeking records on the reported eagle deaths and injuries within two miles of Seven Mile Hill I/II, Ekola Flats, and Dunlap wind projects in southern Wyoming.
The Interior Department responded by releasing 910 pages, while another 256 pages were redacted. The agency withheld the records under Exemption 4, which blocks the revelation of “trade secrets and commercial or financial information obtained from a person [that is] privileged or confidential.”

The group filed an administrative appeal in May, challenging the exemption and demanding that the department release all the data it has related to the request.
The ACC received no response to their appeal, and so they filed a lawsuit in the U.S. District Court for the District of Columbia.

Wind energy developers have been targeting the area of southeast Wyoming, which has some of the richest wind resources in the U.S.
According to the ACC’s lawsuit, there will be 28 utility-scale wind farms operating across Wyoming by this summer, and some projects have over 500 turbines.
“It’s not proprietary. It’s dead eagles,” conservationist says
Anne Brande, executive director of the ACC, told Just the News that the ecological risks of so many projects make transparency in federal oversight all the more imperative.
The law allows a certain number of eagles to be lost via a permitting system called the “eagle take.”
Millions of birds are killed by wind turbines worldwide, every single year.

Wind farm owners collect records on bird mortality as part of the eagle take permits [that] the developers are required to have in order to disturb, injure, and kill eagles.
This data is public information submitted to federal agencies as part of their permitting, Brande said, and there’s nothing in those records that could be legally withheld under Exemption 4.
“It’s not proprietary. It’s dead eagles,” she said.
Birds Just Vanish From Tracking
Lockhart has been tagging eagles in the area of the three wind farms and said that about half the known human-caused eagle deaths of the birds he’s tagged are caused by wind turbines.
However, he said, this is just a glimpse of what could be a much larger impact.
“That’s just a sample, but it’s a very telling sample,” Lockhart said.
Shooting, electrocutions, and road collisions are among the other types of human-caused deaths of eagles. He said many of the tagged birds don’t show up in the data he’s gathered. The tags will show birds flying in the areas of these turbines, and then they just vanish.
“I’m sure that a number of those birds have been killed and are just not reported,” Lockhart said.
This is why the data the federal government is withholding, he said, is so important. It’s likely that the “take” reports that are submitted to the Fish and Wildlife Service show that a lot more birds are dying than what he’s counting, Lockhart believes.
That data could help fill “huge gaps” in the knowledge about the potential impacts of the projects on eagles, he said.

Hey where’s the National Audubon Society? I thought they cared about the Birds! Looks to me like they prefer Ideology and Cash over the Eagles
Not surprising that the agency is hiding the real data from the public. But if it were a dozen Canadian geese who died in an oil retention pond that would be all over the news even though there are millions of geese whose females lay a large number of eggs each summer while a female eagle lays 2 or maybe 3 eggs and frequently not all will hatch. And there are no where near as many eagles as there are geese.
