BILLINGS, Mont. — The Trump administration moved forward Friday with plans to scale back a century-old law protecting most American wild bird species despite warnings that billions of birds could die as a result.
Officials said in a draft study of the proposal that it could result in more deaths of birds that land in oil pits or collide with power lines or other structures.
More than 1,000 species are covered under the law, and the changes have drawn a sharp backlash from organizations that advocate on behalf of an estimated 46 million U.S. birdwatchers.
The study did not put a number on how many more birds could die but said some vulnerable species could decline to the point where they would require protection under the Endangered Species Act.
Former U.S. Fish and Wildlife Service Director Dan Ashe and independent scientists have said the change could could cause a huge spike in bird deaths — potentially billions of birds in coming decades — at a time when species across North America already are in steep decline.
The proposal would end the government’s decadeslong practice of treating accidental bird deaths caused by industry as potential criminal violations under the Migratory Bird Treaty Act.
Industry sources kill an estimated 450 million to 1.1 billion birds annually, out of an overall 7.2 billion birds in North America, according to the U.S. Fish and Wildlife Service and recent studies.
The 1918 migratory bird law came after many U.S. bird populations had been decimated by hunting and poaching — much of it for feathers for women’s hats.
It was one of the country’s first major federal environmental laws, enacted just after the conservation movement embodied by President Teddy Roosevelt had emerged as a new force in American politics.
Over the past half-century, as new threats to birds emerged, the law also was applied against companies that failed to prevent foreseeable bird deaths, such as oil companies that did not put netting over toxic waste pits despite warnings from federal officials.
However, the Trump administration has said the deaths of birds that fly into oil pits, mining sites, telecommunications towers, wind turbines and other hazards should be treated as accidents not subject to prosecution.
A final decision is expected following a 45-day public comment period.
A Department of Interior legal decision in 2017 already had effectively ended criminal enforcement under the act during Trump’s presidency. The pending proposal would cement that interpretation of the law into government regulation, thus making it harder to reverse by subsequent administrations.
U.S. Fish and Wildlife officials said the proposal was meant to match up with the 2017 legal decision.
“We believe this is the only viable alternative in line with this legal conclusion,” the agency said in a statement.
National Audubon Society President David Yarnold said the administration was ignoring the potential devastation to some species from scaling back protections and siding with corporations over the environment.
“While America is in turmoil, the Trump administration is continuing its relentless war on nature,” Yarnold said.
Eight states led by New York and numerous conservation groups including Audubon have challenged the 2017 decision in U.S. District Court.
