It sounds like a set-up for an ecological horror film \u2013 to save one species of owl, US wildlife officials want to shoot down half a million of its cousins.<\/p>\n
The federal government\u2019s latest proposal to save the endangered spotted owls has raised complicated questions about the ethics of killing one species to save another, and the role of humans to intervene in the cascading ecological conundrums that they have caused.<\/p>\n
The spotted owl \u2013 an elusive icon of the American west \u2013 has lost most of its habitat in the old growth forests of the Pacific north-west and Canada due to logging and development. The species has also faced increasing competition from the barred owl \u2013 a slightly larger, more successful cousin which was lured west over the last century as settlers and homesteaders reshaped the North American landscape.<\/p>\n
Now, to save the spotted owls, the US Fish and Wildlife Service has finalised a proposal to cull hundreds of thousands of barred owls across California, Washington and Oregon over the next 30 years.<\/p>\n
The plan has pitted animal welfare and conservation groups against each other. The proposal was published in November, but it drew renewed attention last week after 82 animal welfare organisations based around the US signed a letter calling it \u201ccolossally reckless\u201d. Researchers and wildlife officials who support the plan have said that if the barred owls are not culled, the northern spotted owl\u2019s demise is ensured.<\/p>\n
\u201cThis is a case that poses a genuine ethical dilemma,\u201d said Michael Paul Nelson, a professor of environmental ethics and philosophy at Oregon State University. \u201cYou\u2019re either going to kill a bunch of individual living beings, or you\u2019re going to let a species disappear. No matter what, harm is done.\u201d<\/p>\nThe spotted owl has lost most of its habitat and in the Pacific north-west and Canada. Photograph: All Canada Photos\/Alamy<\/figcaption><\/figure>\n
An invasive species, or natural competition?<\/h2>\n
Spotted and barred owls look very similar to the untrained eye, and they can interbreed to birth offspring that are called \u201csparred owls\u201d. But the barred owls are more adept survivors. They hunt a greater variety of prey, are slightly less discerning about where they nest, and tend to reproduce more quickly. And over the past few decades, biologists have noticed that the barred owls are edging the spotted owls out of their territory.<\/p>\n
\u201cBarred owl removal is not something the Service takes lightly,\u201d said Jodie Delavan, a public affairs officer with USFWS in Oregon. \u201cHowever, the Service has a legal and ethical responsibility to do all it can to recover northern spotted owl populations. Unless invasive barred owls are managed, the federally listed northern spotted owl will be extirpated in all or a significant portion of its range.\u201d<\/p>\n
The northern spotted owls were listed as threatened in 1990 after fierce campaigning by environmentalists who fought to protect the ancient forests where the birds nest from the logging. But the protections came too late \u2013 70% of their habitat is already gone. The climate crisis and increasingly fierce megafires now threaten to destroy what little remains of their forest habitats.<\/p>\n

The arrival of barred owls in the west appears to have hastened the spotted owl\u2019s decline. It\u2019s unclear why exactly the barred owls migrated westward, but researchers agree that it coincided with the arrival of European settlers in the east, and their reshaping of the owls\u2019 native landscape. Previously, a scarcity of tree habitats in the Great Plains may have prevented the barred owls from venturing west until homesteaders planted trees for lumber, which provided new habitats. They also abandoned or outlawed Indigenous forest management practices, trapped beavers, over-hunted deer and elk, and drove away bison \u2013 all of which caused forests to overgrow.<\/p>\n
That\u2019s one of the reasons that the Fish and Wildlife Service, and biologists, consider the barred owls to be an invasive species \u2013 human intervention led to their arrival in the west. And that is why many believe it is humans\u2019 responsibility to remove them.<\/p>\n
\u201cI grappled with it constantly. It\u2019s not an easy thing,\u201d said David Wiens, a wildlife biologist with the US Geological Survey who has spent his career studying interactions between spotted owls and barred owls. Several years ago, he and fellow researchers ran an experiment that involved shooting more than 2,400 barred owls across the north-west \u2013 and found that over five years, culling the barred owls helped spotted owl populations stabilise.<\/p>\nA male hybrid owl, produced by a northern spotted owl and a barred owl, in Oregon.

Even as the researchers culled barred owls, however, more of them moved in. In order to truly control their populations in the west, hunters would have to keep shooting them over a long period of time. \u201cIt\u2019s a very tough decision,\u201d he said. \u201cDo you use lethal removal techniques? Or do you do nothing \u2013 just throw up your hands and let the cards fall where they will?\u201d<\/p>\n
Many conservationists have \u2013 squeamishly \u2013 agreed that the barred owls should be culled. But animal rights activists, some wildlife groups and the editorial board of the Los Angeles Times remains sceptical.<\/p>\n
\u201cThe United States is targeting a native species not ever hunted for simply engaging in normal range expansions,\u201d said Wayne Pacelle, president of the Center for a Human Economy and its lobbying arm, Animal Wellness Action, who co-authored the letter opposing the culling proposal. \u201cIf the US Fish and Wildlife Service is now going to start to manage social conflicts between animals, where does this end?\u201d<\/p>\n
Pacelle disputes the idea that the barred owl is invasive \u2013 as it is, after all, native to North America. And killing hundreds of thousands of them, over three decades, in an area where they are guaranteed to keep returning is \u201cunworkable and inhumane\u201d, he said.<\/p>\n
The trouble is, he added, \u201cwe don\u2019t have an easy fix for the spotted owl.\u201d<\/p>\n
Fraught questions for the Anthropocene<\/h2>\n
For Lisa Sideris, a professor of environmental studies at the University of California, Santa Barbara, who specialises in environmental ethics and the intersections of science and religion, the case of the two owls inspires introspection about the follies of anthropocentrism. \u201cSome would argue that humans have altered ecosystems and the whole planet to such an extent that it becomes very hard to discern what it would mean to restore something back to natural conditions and whether that\u2019s even possible.\u201d<\/p>\n
This isn\u2019t the first time the coy spotted owls have pushed people to grapple with fraught philosophical ideas. \u201cThe spotted owl has been the poster animal for environmental conflicts for decades,\u201d said Sideris.<\/p>\n
The species found itself at the centre of what became known as the Timber Wars in the 1980s and 1990s. Loggers and environmentalists seeking to save old growth forests in California and the Pacific north-west clashed \u2013 in the courtroom and in the woods. In Oakland, California, Judi Bari and Darryl Cherney – two anti-logging activists campaigning to save the spotted owl \u2013 were critically injured by a pipe bomb that exploded under their car. In 1990, amid escalating conflict, the spotted owl was listed as threatened under the Endangered Species Act \u2013 and made the cover of Time magazine.<\/p>\n
Still, tensions between timber industry leaders \u2013 who said that efforts to save the owl would cost tens of thousands of jobs \u2013 and environmentalists continued to build. In 2021, the Trump administration drastically slashed protections for the spotted owl. Joe Biden reversed the decision, but conceded 200,000 acres in owl habitat as part of the settlement of a timber industry lawsuit.<\/p>\n
The spotted owl and the barred owl remain caught in the political crossfire. And all the while, wildlife officials and biologists are left with fraught questions about how best to save the species under strained circumstances.<\/p>\nThere is debate over whether the barred owl, pictured, is considered \u2018invasive\u2019 to the US west and should be culled.

Getting rid of the barred owls is ultimately a \u201ctriage\u201d \u2013 a way to give the spotted owl some more time, and a fighting chance at survival, said Tom Wheeler, executive director of the conservation group Epic. \u201cDoes this just mean that there will always have to be somebody with a shotgun in our forest killing owls?\u201d said Wheeler. \u201cI think that we have to \u2013 as supporters of this \u2013 somewhat acknowledge that that is a possibility. And we have to be OK with that.\u201d<\/p>\n
Preventing extinction has become a sisyphean task, said Nelson, and despite government, scientists and conservationists\u2019 best efforts, it remains impossible to predict or control exactly how nature will react.<\/p>\n
\u201cThere is a hubris that underlies this idea that we\u2019re just going to engineer our way out of these situations,\u201d he said. \u201cBecause that is the same attitude that created these problems in the first place.\u201d<\/p>\n
