How the Migratory Bird Treaty Act could become the administration’s ultimate weapon against wind farms.

The Trump administration has quietly opened the door to strictly enforcing a migratory bird protection law in a way that could cast a legal cloud over wind farms across the country.
As I’ve chronicled for Heatmap, the Interior Department over the past month expanded its ongoing investigation of the wind industry’s wildlife impacts to go after turbines for killing imperiled bald and golden eagles, sending voluminous records requests to developers. We’ve discussed here how avian conservation activists and even some former government wildlife staff are reporting spikes in golden eagle mortality in areas with operating wind projects. Whether these eagle deaths were allowable under the law – the Bald and Golden Eagle Protection Act – is going to wind up being a question for regulators and courts if Interior progresses further against specific facilities. Irrespective of what one thinks about the merits of wind energy, it’s extremely likely that a federal government already hostile to wind power will use the law to apply even more pressure on developers.
What’s received less attention than the eagles is that Trump’s team signaled it could go even further by using the Migratory Bird Treaty Act, a separate statute intended to support bird species flying south through the U.S. from Canada during typical seasonal migration periods. At the bottom of an Interior press release published in late July, the department admitted it was beginning a “careful review of avian mortality rates associated with the development of wind energy projects located in migratory flight paths,” and would determine whether migratory birds dying because of wind farms qualified as “‘incidental’ takings” – harm or death – under the Migratory Bird Treaty Act.
While not stated explicitly, what this means is that the department appears to be considering whether to redefine these deaths as intentional under the Migratory Bird Treaty Act, according to Ben Cowan, a lawyer with the law firm Troutman Pepper Locke.
I reached out to Cowan after the eagle investigation began because his law firm posted a bulletin warning that developers “holding active eagle permits” might want to prepare for “subpoenas that may be forthcoming.” During our chat earlier this month, he told me that the eagle probe is likely going to strain financing for projects even on private lands that wouldn’t require any other forms of federal sign-off: “Folks don’t want to operate if they feel there’s a significant risk they might take an eagle without authorization.”
Cowan then voiced increasing concern about the migratory bird effort, however, because the law on this matter could be a quite powerful – if legally questionable – weapon against wind development.
Unlike the Endangered Species Act or the eagle protection law, there is currently no program on the books for a wind project developer to even obtain a permit for incidental impacts to a migratory bird. Part of the reason for the absence of such a program is the usual federal bureaucratic struggle that comes with implementing a complex statute, with the added effect of the ping-pong of federal control; the Biden administration started a process for permitting “incidental” impacts, but it was scrapped in April by the Trump team. Most protection of migratory birds under the law today comes from voluntary measures conducted by private companies and nonprofits in consultation with the federal government.
Hypothetically, hurting a migratory bird should be legally permissible to the federal government. That’s because the administration loosened implementation of the law earlier this year with an Interior Department legal opinion that stated the agency would only go after harm that was “intentional” – a term of art under the statute.
This is precisely why Cowan is fretting about migratory birds, however. Asked why the wind industry hasn’t publicly voiced more anxiety about this potential move, he said industry insiders genuinely hope this is “bluster” because such a selective use of this law “would be so beyond the pale.”
“It’s basically saying the purpose of a wind farm is to kill migratory birds, which is very clearly not the case – it’s to generate renewable electricity,” Cowan told me, adding that any effort by the Interior Department would inevitably result in lawsuits. “I mean, look at what this interpretation would mean: To classify it as intentional take would say the purpose of operating a wind farm would be to kill a bird. It’s obviously not. But this seems to be a way this administration is contemplating using the MBTA to block the operation of wind farms.”
It’s worth acknowledging just how bonkers this notion is on first blush. Is the federal government actually going to decide that any operating wind farm could be illegal? That would put entire states’ power supplies – including GOP-heavy states like Iowa – in total jeopardy. Not to mention it would be harmful overall to take operating capacity offline in any fashion at a moment when energy demand is spiking because of data centers and artificial intelligence. Even I, someone who has broken quite a few eye-popping stories about Trump’s war on renewables, struggle to process the idea of the government truly going there on the MBTA.
And yet, a door to this activity is now open, like a cleaver hanging over the industry’s head.
I asked the Interior Department to clarify its timeline for the MBTA review. It declined to comment on the matter. I would note that in mid-August, the Trump administration began maintenance on a federal dashboard for tracking regulations such as these and hasn’t updated it since. So we’ll have to wait for nothing less than their word to know what direction this is going in.

Much of California’s biggest county is now off limits to energy storage.
Residents of a tiny unincorporated community outside of Los Angeles have trounced a giant battery project in court — and in the process seem to have blocked energy storage projects in more than half of L.A. County, the biggest county in California.
A band of frustrated homeowners and businesses have for years aggressively fought a Hecate battery storage project proposed in Acton, California, a rural unincorporated community of about 7,000 residents, miles east of the L.A. metro area. As I wrote in my first feature for The Fight over a year ago, this effort was largely motivated by concerns about Acton as a high wildfire risk area. Residents worried that in the event of a large fire, a major battery installation would make an already difficult emergency response situation more dangerous. Acton leaders expressly opposed the project in deliberations before L.A. County planning officials, arguing that BESS facilities in general were not allowed under the existing zoning code in unincorporated areas.
On the other side, county officials maintained that the code was silent on battery storage as such, but said that in their view, these projects were comparable to distribution infrastructure from a land use perspective, and therefore would be allowable under the code.
Last week, the residents of Acton won, getting the courts to toss out the county’s 2021 memorandum allowing battery storage facilities in unincorporated areas – which make up more than 65% of L.A. County.
Judge Curtis Kin wrote in his October 14 ruling that “such expansive use of the interpretation runs contrary to the Zoning Code itself,” and that the “exclusion” of permission for battery storage in the code means it isn’t allowed, plain and simple.
“Consequently, respondents and real parties’ reliance on the existence of other interpretive memos and guidance by the [Planning] Director is beside the point,” Kin stated. “There is no dispute the Director has the authority to issue memos and interpretations for Zoning code provisions subject to interpretation, but, as discussed above, such authority cannot be used in such a way as to violate the provisions of the Zoning Code.”
The court also declared the Hecate project approval void and ordered the company to seek permits under the California Environmental Quality Act if it still wants to build. This will halt the project’s development for the foreseeable future. Alene Taber, the attorney representing Acton residents, told me she has received no indication from Hecate’s legal team about whether they will appeal the ruling.
Hecate declined to comment on the outcome.
Taber’s perspective is unique as a self-described “rural rights” attorney who largely represents unincorporated communities with various legal disputes. She told me this ruling demonstrates a serious risk regulators face in moving too fast for a host community, especially given rising opposition to battery storage in California. Since the Moss Landing fire, opposition to storage projects has escalated rapidly across the state – despite profound tech differences between more modern designs proposed today and the antiquated system that burned up in that incident.
I asked Taber if she thought California enacting a new law last week to beef up battery fire safety oversight could stem the tide of concerns about battery storage. In response, she railed against a separate statute giving energy companies – including battery developers – the ability to work around town ordinances and moratoria targeting their industry.
“Even though the county didn’t consider the community input — which it should’ve — the county process at least still allowed for communities to appeal the project. And they’re also at least supposed to consider what the local zoning code said,” Taber told me. “Local communities are now sidelined all together. They’re saying they don’t care what the concerns are. Where’s the consideration for how these projects are now being sited in high fire zones?”
I was unable to reach Los Angeles County officials before press time for The Fight, but it’s worth noting that, amid the battle over Hecate’s approval, L.A. County planning officials began preparing to update their renewable energy ordinance to include battery storage development regulation – an indication they may need new methods to site and build more battery storage. There’s no timeline for when those changes will take place.
And more of the week’s top news about renewable energy conflicts.
1. Benton County, Washington – A state permitting board has overridden Governor Bob Ferguson to limit the size of what would’ve been Washington’s largest wind project over concerns about hawks.
2. Adams County, Colorado – This is a new one: Solar project opponents here are making calls to residents impersonating the developer to collect payments.
3. Lander County, Nevada – Trump’s move to kill the Esmeralda 7 solar mega-project has prompted incredible backlash in Congress, as almost all of Nevada’s congressional delegation claims that not a single renewables project in the U.S. has gotten a federal permit since July.
A conversation with David Gahl of SI2
This week I spoke with David Gahl, executive director of the Solar and Storage Industries Institute, or SI2, which is the Solar Energy Industries Association’s independent industry research arm. Usually I’d chat with Gahl about the many different studies and social science efforts they undertake to try and better understand siting conflicts in the U.S.. But SI2 reached out first this time, hoping to talk about how all of that work could be undermined by the Trump administration’s grant funding cuts tied to the government shutdown. (The Energy Department did not immediately get back to me with a request for comment for this story, citing the shutdown.)
The following conversation was edited lightly for clarity.
So what SI2 funding could be cut because of the federal shutdown, and what has it been put toward?
On October 1, the Energy Department put out a list of about $7.5 billion in grants they were terminating. Approximately a week later, another larger list of grants that were slated for termination found its way into the press. There’s an outstanding question about what this other list floating around means, and only DOE can verify the document’s accuracy, but we have two projects that were on that bigger list.
The first was $2.5 million supporting research into how power companies engage communities. We were coming up with a list of community engagement innovations — the idea was to actually test, through rigorous social science research at project sites, which of these innovations produces the best outcomes. We were going to have empirical data that said, If you approach communities in this way you’re more likely to get support, and if you approach communities this other way you wouldn’t.
The second was $3 million to bring diverse stakeholders together to talk about siting and permitting reform, best practices, guidance to make development smoother. The concept there was to bring traditionally warring parties to come up with a framework and tools to help the siting process. If you can get people together to come up with best practices, you can typically move things faster.
This was an “uncommon dialogue” – there was “uncommon dialogue” before on hydropower resources – and this was related to large-scale solar facilities and conservation. It’s not location-specific, more bringing the groups together to talk about a higher level set of issues, not specific projects. Keep in mind, this is relatively small potatoes.
What was the status of that work?
It started earlier in the year and it’s been rolling along. There’s been a lot of progress made so far. People have developed work plans and are working through the issues.
If the funding is canceled, there’s also opportunity for private money to potentially step in, but it puts both initiatives in a precarious place. But to the broader point, the administration has talked about how it wants energy “abundance” and more electrons on the grid to meet growing demand. And these projects funded by the department are addressing key problems to putting electrons onto the grid. Cancellation of these grants is just a complete reversal of what they’re talking about in other forums.
How so? Help me understand how this work actually trickles down to individual project decisions.
One of the challenges with siting any kind of large-scale energy project is getting community buy-in and ensuring the permitting process moves smoothly, that parties aren’t going to be litigating against each other. So if you can come up with ways to make sure the communities feel heard and are designed according to what communities want, you can probably avoid some litigation down the road.
Do you have any indication this government supports the work you’re describing?
What they’ve made clear is they want more electrons to come onto the grid to support data centers and the advancement of artificial intelligence. Canceling grants like these … I mean, we’re talking about potentially canceling projects that make it harder to meet the goal of putting more electricity onto the grid.
