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

But during migration season, a much smaller squad of New York City volunteers take on a more sobering experience: counting dead birds that have collided with glass buildings and fallen back to Earth.

In this episode, we find out what kind of people volunteer for this grisly job, visit the New York City rehab center that takes in injured pigeons, and find out how to stop glass from killing an estimated one billion birds nationwide every year.

Featuring Melissa Breyer, Linda LaBella, Gitanjali Bhattacharjee, Katherine Chen, and Tristan Higginbotham

The Smithsonian National Zoological Park in Washington, DC is sometimes called “the people’s zoo.” That’s because it’s the only zoo in the country to be created by an act of US Congress, and admission is free.

But why did our federal government create a national zoo in the first place?

Producer Felix Poon has the scoop – from its surprising origins in the near-extinction of bison, to a look at its modern-day mission of conservation, we’re going on a field trip to learn all about the National Zoo.

Featuring Kara Ingraham, Daniel Frank, and Ellie Tahmaseb.

While digging a well in 1750, a group of workers accidentally discovered an ancient Roman villa containing over a thousand papyrus scrolls. This was a stunning discovery: the only library from antiquity ever found in situ. But the scrolls were blackened and fragile, turned almost to ash by the eruption of Mount Vesuvius.

Over the centuries, scholars’ many attempts to unroll the fragile scrolls have mostly been catastrophic. But now, scientists are trying again, this time with the help of Silicon Valley and some of the most advanced technology we’ve got: particle accelerators, CT scanners, and AI.

After two thousand years, will we finally be able to read the scrolls?

The Colorado River – and the people that rely on it – are in a state of crisis. Climate change and overuse are taking a significant toll. Seven states must compromise and reach a solution to prevent the river from collapsing.

In late 2023, tensions were running high between the major players in the water world as they convened at the annual Colorado River conference in Las Vegas. LAist Correspondent Emily Guerin was there, seeking to learn as much as she can about the people with the most power on the river, including a sharply-dressed 28-year-old from California.

This episode comes to us from the podcast Imperfect Paradise, which is releasing a whole series on the Colorado River water crisis.

Agriculture uses a lot of the Colorado River - what if we replaced that farmland with solar panels?

Speaking of farms, most of the crops raised with Colorado River water don’t go to people. They go to cows.

You might associate it with the foil that wraps leftover pizza and the shiny craft beer cans sold in breweries, but aluminum is literally everywhere. Scoop up a handful of soil or gravel anywhere on Earth, and you’ll find atoms of bonded aluminum hidden inside. Over the past 150 years, that abundance has led production of the silvery metal to skyrocket (pun intended) and created an industry responsible for 2-3% of global greenhouse gas emissions.

But even before it was used in everything from airplanes to deodorant, the trade of aluminum minerals helped color the world, finance the Vatican, and led to the mass collection of human urine.

In this episode, we’re piloting a new segment called “The Element of Surprise.” It’s all about the hidden histories behind the periodic table’s most unassuming atoms, isotopes, and molecules. And we’re kicking things off with aluminum.

Editor's note: A previous version of this episode misstated the number of Allied casualties during a 1943 bombing campaign against a German cryolite factory, claiming all but one of 180 bombers were destroyed. In actuality, all but one of 180 bombers returned home safely. The episode has been corrected.

The World Economic Forum has published a number of studies and articles on the need to decarbonize the aluminum industry and the promising technologies that might help us get there.

A few years ago, Alcoa announced plans to build a new aluminum smelting plant in Maniitsoq, Greenland. PBS’s POV released a documentary about how people there reckoned with the island’s colonial past as the project progressed, stalled, and eventually collapsed.

The National Park Service has a fun little read about the Washington Monument’s aluminum tip.

Sean Adams, at the University of Florida, wrote an excellent recap of the U.S. government’s antitrust case against aluminum giant Alcoa.

Here’s another one from Foreign Policy about how industrial cartels and monopolies helped Hitler gain power.

Check out Charlie Halloran’s “The Alcoa Sessions,” to imagine what kind of music might have been played during Alcoa’s cruise voyages between New Orleans and Jamaica between 1949 and 1959.

When officials commissioned a set of updated hazard maps for Juneau, Alaska, they thought the information would help save lives and spur new development. Instead, the new maps drew public outcry from people who woke up to discover their homes were at risk of being wiped out by landslides.

What’s followed has been a multiyear project – not to address the challenges posed by climate-fueled landslides – but to alter, ignore, or otherwise shelve the maps that outline the threat in the first place.

Host Nate Hegyi visits Juneau to see one example of why, across the country, even the most progressive Americans are rejecting tough truths about climate change when it comes knocking at their own back door.

When it comes to protecting the biodiversity of Planet Earth, there is no greater failure than extinction. Thankfully, only a few dozen species have been officially declared extinct by the US Fish and Wildlife Service in the half-century since the passage of the Endangered Species Act.

But, hold on. Aren’t we in the middle of the sixth mass extinction? Shouldn’t the list of extinct species be… way longer? Well, yeah. Maybe.

Producer Taylor Quimby sets out to understand why it’s so difficult to officially declare an animal extinct. Along the way, he compares rare animals to missing socks, finds a way to invoke Lizzo during an investigation of an endangered species of crabgrass, and learns about the disturbing concept of “dark extinctions.”

Editor's Note: This episode was first published in October 2022. Since then, the US Fish and Wildlife Service officially delisted 21 of 23 proposed species due to extinction. The ivory-billed woodpecker was not one of them.

Featuring Sharon Marino, Arne Mooers, Sean O’Brien, Bill Nichols, and Wes Knapp.

Shirtless influencers on TikTok and Instagram have acquired millions of followers promoting the carnivore diet. They say studies linking meat consumption and heart disease are flawed — and plant foods are making people sick. "Western medicine is lying to you," says content-creator Dr. Paul Saladino, who co-owns a company selling desiccated cattle organs.

The online popularity of the carnivore diet is undeniable. Yet, no controlled studies have been published confirming its advertised benefits.

Our friends at WBUR’s podcast Endless Thread look at how social media cooked up the anti-establishment wellness trend.
