Night Owls
For over ten years, biologist Mark Higley has been stalking the forests of the Hoopa Valley Reservation with a shotgun. His mission? To save the endangered northern spotted owl. How? By shooting the more aggressive barred owl, which has spread from eastern forests into the Pacific Northwest. In 2024, the federal government made a plan to scale these efforts by killing hundreds of thousands of barred owls across multiple states. Today, despite lawsuits and opposition, that plan is just beginning to ramp up. But can it really save the northern spotted owl? And is the barred owl really “invasive”… or just expanding its range? In this episode, Nate Hegyi dons a headlamp and heads into the forest with Mark Higley to catch a glimpse of these two rivals, and find out what it takes to kill these charismatic raptors, night after night, in the name of conservation. This episode was first published in 2024. Featuring Mark Higley, Tom Wheeler, and Wayne Pacelle. SUPPORT Outside/In is made possible with listener support.

The sunscreen episode
As consumers, we’re looking for a lot in our sunscreen. Not only do we want it to protect us from sunburns and skin cancer, we also want it to be invisible, lightweight, waterproof, nontoxic, shelf-stable, and cheap. Can we have it all in one product? Sometimes, the answer might be no. It’s high time for the Outside/In team to take a closer look at this surprisingly high-tech lotion that we apply every day (in theory). We review the definition of SPF, the choice between mineral and chemical filters, and if sunscreen is safe for our bodies and the environment.

To the American birder, spotting the Tamaulipas Crow is potentially a once-in-a-lifetime event. The crow's range is mostly in Mexico and extends ever so slightly into Texas, specifically in and around a dump called the Brownsville Landfill. Spotting the Tamaulipas — north of the border — means being able to check it off your American Bird Association Checklist. So just how far will die-hard birders go to see this bird? In this episode producer (and first-time birder) Michaela Elias sets out to the southern border with a group of experienced birder friends to find out. Together with her "wingmen" Michaela braves the Texas heat, crawls through brush and over slippery rocks, and risks getting attacked by dogs — to find out whether collecting bird sightings as if they're Pokémon is a meaningful way to engage with the natural world.

Pickleball is the fastest growing sport in America. It may also be the most hated. Tennis and basketball players are complaining about losing court space because of an “invasion” of pickleballers. Residents are losing sleep because of the incessant noise. Fights over pickleball have led to a slew of petitions, calls to the police, and even lawsuits. So why do pickleball players love this sport so much? Just how annoying is it to everyone else? And what will it take for everyone to just get along? Producer Felix Poon visits one of the most popular courts in Boston to see how the drama is unfolding there. This episode was originally reported in 2025.

A listener recently asked, “Has the entire surface of earth at some point or another been covered in poop?” Turns out, there are some questions that even we can’t answer. In this installment of our regular mailbag segment, the Outside/Inbox, we do our best to take on your zany inquiries, or find experts who can. Here are this week’s questions: Why was there a sudden spike in “dangerous carbon monoxide levels” during a snowstorm in New Hampshire? Is there any official recognition for hiking the Appalachian Trail, Pacific Crest Trail, and the Continental Divide Trail? Why are live scorpions allowed in the mail? Why do kids (and adults) chant “Do it! Do it! Do it!” and other chants? Do all predators have forward-facing eyes? Featuring Kathleen Simmons, Carlos Santibanez-Lopez, and Barb Lake.

Big porpoise energy
Whales have Free Willy. Dolphins have Flipper. But what about the humble porpoise? The porpoise doesn’t star in any Hollywood blockbusters. These shy, elusive “deer of the sea” are often overshadowed by their more charismatic cousins – but don’t let their social anxiety fool you. In fact, porpoises are speed-fiends with an insane metabolism and an outrageous sex drive. Host Nate Hegyi and producer Marina Henke explore the Olympic sprinters of the sea and wonder if the fate of the endangered vaquita might hinge on being oh-so-very-cute.

A tinned fish renaissance

Literally. They are in Vogue magazine. They’re delicious (subjectively), good for you, and sustainable… right? Recently, a listener called into the show asking about just that. “I've always had this sense that they're a more environmentally friendly fish, perhaps because of being low on the food chain. But I'm realizing I really have no sense of what it looks like to actually fish for sardines,” Jeannie told us. The Outside/In team got together to look beyond the sunny illustrations on the fish tins. Is there bycatch? What about emissions? Are sardines overfished? If we care about the health of the ocean, can we keep eating sardines? This episode was originally published in 2025. Featuring Jeannie Bartlett, Malin Pinsky, and Zach Koehn.

In defense of darkness
Megan Eaves-Egenes grew up under the very starry skies of rural New Mexico. During those years, she developed a deep appreciation for astronomy. The fascination is, of course, not hers alone. But, a starry sky requires one pretty important ingredient: darkness. One study recently reported that since 2011, the night sky has gotten brighter at about 10% per year. All that light pollution has brought dire consequences to life on planet earth. Crickets can’t tell whether it’s day or night, bird migrations have gone haywire, and our own natural alarm clocks are constantly confused. In a world where switching on a lamp during evening hours is, as Megan writes, “almost as basic as breathing” is there hope for our night skies? Or have we illuminated our way to a point of no return? Featuring Megan Eaves-Egenes. SUPPORT To share your questions and feedback with Outside/In, call the show’s hotline and leave us a voicemail.

President Trump recently signed an executive order to make certain psychedelic drugs more available to treat mental health conditions like depression and PTSD. Robert F. Kennedy Jr. and Joe Rogan were in the oval office, and President Trump even joked during the signing ceremony, “can I have some, please?” Maybe this executive order wasn’t on your 2026 political bingo card… but interest in these substances for mental health isn’t new. In this episode, we’re revisiting the story of Kathy Kral. In the midst of her battle with cancer, Kathy found herself facing a diagnosis of major depression. So, she signed up for a clinical study to see if psilocybin – the psychedelic compound found in “magic mushrooms” – could help her confront her fears about cancer and death, as well as her deepest inner demons.

Silicon Planet
Like a typecast actor who can’t escape the blockbuster franchise they’re known for, the element of silicon is inescapably associated with Silicon Valley. But that association undersells just how important, how foundational silicon is for human civilization. It’s another edition of “The Element of Surprise,” our occasional series about the hidden stories behind the periodic table’s most unassuming atoms, isotopes, and molecules. And this time, it’s all about silicon. From humankind’s early tools, to the quartz crystal hidden in your digital watch, we’ll cover how this underrated element has a lot more to offer than one California valley might suggest.

In the spring of 1936, the producer of King Kong hauled a film crew to the desert of Arizona to shoot a sweeping romantic epic. But the heat was so punishing that it melted film stock, caused the lead actress to pass out, and killed the production’s mascot – a baby camel. It was the beginning of a heat wave that parked itself over America for months, quickly becoming one of the deadliest natural disasters in our country’s history. It blew up sidewalks, cooked onions in the ground, claimed at least 12,000 lives, and turned the United States into a literal frying pan. Host Nate Hegyi talks with Geoff Williams, author of the forthcoming book The Summer of Death, about a ‘heat horror show’ that transformed American life 90 years ago, and what lessons it gives us on how to survive a hotter world today.

Every December, tens of thousands of volunteers look to the skies for an international census of wild birds.
