One year ago, a landmark study published in the journal Science made headlines around the world. The most robust population assessment of North America’s birds ever conducted revealed a stunning 29% decline since 1970—or almost 3 billion birds lost from the continental bird population in just a few decades.

“We were stunned by the result—it’s just staggering,” the study’s lead author, Cornell Lab of Ornithology conservation scientist Ken Rosenberg, told The New York Times in a front-page story published on Sept. 20, 2019.

On May 10, 2020, The New York Times published a list of 100 federal environmental rules in the United States that the Administration has reversed or is in the process of reversing. The rollbacks range from granting federal permission for more air pollution and greenhouse-gas emissions to stripping protections for wildlife and waters. Bedrock American environmental policy dating back to the Nixon, Wilson, and even the Theodore Roosevelt Administrations have been chipped up and broken apart over the past four years.

The onslaught has included direct attacks on bird conservation policy, such as the crippling of the 102-year old Migratory Bird Treaty Act and weakening of the Endangered Species Act. Bird populations are also likely to be affected by the weakened protections for America’s lands and waters. Birds pay dearly when ecosystems are compromised and polluted.

The next four years present an opportunity to foster policies that rebuild and restore America’s bird populations, and avoid what Rosenberg and his study coauthors warned us about—a “collapse of the continental avifauna.”

More than 100 steeply declining bird species will face higher mortality due to a weakened Migratory Bird Treaty Act. From left: Swainson’s Thrush, Black-and-white Warbler, Common Yellowthroat, and Barn Swallow have each declined by 20% or more since 1970.

Bedrock Environmental Policy Is Crumbling

Among the 100 environmental rules rolled back over the past four years, there are several areas where weakened federal policy will exacerbate bird declines.

Weakening the Migratory Bird Treaty Act (December 2017)

The Migratory Bird Treaty Act was born with President Woodrow Wilson’s signature in 1916, a pledge between the U.S. and Canada to protect the migratory birds of North America from unregulated killing, or take. In a 2018 essay for Living Bird, Lynn Scarlett— former deputy secretary of the Interior under President George W. Bush—wrote about that long-standing definition of take: “For at least five decades, Republican and Democratic administrations alike have understood the Act to prohibit the ‘taking’ and ‘killing’ of birds … not just against hunting without permits, but also against ‘incidental take’ from foreseeable harms like oil spills, wind turbines, and transmission lines.” The MBTA triggered $100 million in penalties against the companies responsible for the Deepwater Horizon oil well blowout, which killed 1 million birds.  

In December 2017, the Interior deputy solicitor issued a memorandum excluding incidental take from MBTA enforcement, meaning that industry would no longer face penalties for bird kills caused by negligence. In August 2020, a federal district court judge struck down the solicitor’s opinion. However, at press time, Interior appeared to be moving forward with a rule change to exclude incidental take from the Migratory Bird Treaty Act.

Pinyon Jays are in steep decline (4 in 5 lost since 1970) and will be highly affected by the loss of protected habitat on public lands.

Dropping Protection for Public Lands (December 2017)

The Presidential legacy of protecting America’s wildest lands goes back to President Lincoln (who protected Yosemite Valley) and President Grant (who established Yellowstone National Park). Since President Theodore Roosevelt signed the Antiquities Act of 1906, establishing the presidential power to protect lands as national monuments, every U.S. president has grown the area of America’s protected public lands—until now.  

In December 2017, the Administration reduced the Bears Ears and Grand Staircase–Escalante National Monuments in Utah by 2 million acres to open up areas to oil and gas extraction and mining (the largest rollback of federal land protections in U.S. history). The next year, the Administration reinstated previously canceled federal leases for copper-nickel mining within the watershed of Minnesota’s Boundary Waters Canoe Area.

Diluting the Endangered Species Act (August 2019)  

The Endangered Species Act was signed into law in 1973, committing the United States to protecting and restoring species at risk of extinction. “Nothing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed,” President Richard Nixon said at the Act’s signing. Nearly half of the species on the Endangered Species list at that time were birds, including Bald Eagle, Kirtland’s Warbler, and Brown Pelican—all three of which have since recovered and been delisted.  

In August 2019, the Administration finalized a set of rule changes that weaken the Endangered Species Act by removing automatic protections against take for species listed as threatened under the ESA. The ESA rule changes also make it harder to hold federal agencies accountable for activities that threaten the continued existence of an endangered species, and downplay the role of climate change in designating critical habitat under the ESA.

Northern Pintails (2 in 5 lost since 1970) could suffer steeper population losses due to wetlands protections rollbacks in the Prairie Pothole Region.

Stripping Clean Water Act Protections (September 2019)

The Clean Water Act became law in 1972, at a time when two-thirds of America’s lakes, rivers, and coastal waters were so polluted they were deemed unsafe for fishing or swimming. Congress took strong action—passing the Clean Water Act over the veto of President Nixon—to enact a law regulating the pollution of U.S. waters. Over its first four decades, the Clean Water Act was one of the nation’s most effective environmental laws, significantly decreasing pollutant discharges by industry and reducing the rate of wetlands loss.

Yet in the early 21st century, a third of U.S. waters were still not safe for fishing and swimming, and wetlands were still being lost. In 2015 the Obama Administration finalized the Waters of the U.S. rule to strengthen Clean Water Act protections for the feeder sources (wetlands, ephemeral waters, and streams) that are important to healthy bodies of water.  

In September 2019, the Administration repealed the Waters of the U.S. rule. In early 2020 the Administration released its replacement Navigable Waters Protection Rule, which stripped Clean Water Act protections for more than half of wetlands and a fifth of streams nationwide.

Lesser Yellowlegs (1 in 2 lost since 1970) is a species that can be impacted by federal construction projects that drain wetlands.

Limiting the National Environmental Policy Act (July 2020)  

The National Environmental Policy Act of 1969 has been called an “environmental Bill of Rights” by The Wilderness Society because it requires public participation in the review of proposed projects by federal agencies, as well as the consideration of less environmentally damaging alternatives. The idea to conduct comprehensive environmental reviews of federal projects came out of a series of Senate hearings about Florida’s Everglades in the 1960s that revealed a government working at cross-purposes; while the Interior Department was seeking more land protections, the Army Corps of Engineers was planning dams and canals to drain water out of the Everglades.

NEPA declares a national policy that requires an environmental review of all federal projects and a public-comment period so that citizens have a voice in the process.  

In July 2020, the Administration introduced a rule to limit environmental studies and public comments under NEPA. The proposed rule also allows agencies to designate more projects that do not require environmental assessments.
