Okay, but how bad are cats for birds?
E47. Cats kill billions of birds every year, but where does that number come from, and does the cat on your couch count? Dr. Pete Marra, dean of the Earth Commons at Georgetown University and co-author of Cat Wars, unpacks the science behind one of the most heated fights in bird conservation. Want to go deeper? Pick up Pete’s book, Cat Wars: The Devastating Consequences of a Cuddly Killer, co-written with Chris Santella. In this episode, you'll hear about: How one lighthouse keeper's cat and her offspring caused the extinction of a bird almost as soon as it was discovered Whether that little bell on a cat's collar actually does anything Why New Zealand and Australia are making some of the toughest calls in conservation All audio, video, and images in this episode are either original to Okay, But...

Okay, but why are we obsessed with crows and ravens?
E46. Crows and ravens fill our oldest stories, and plenty of us want one as a friend. Dr. Claudia Wascher, professor of behavioral biology at Anglia Ruskin University, explains what makes corvids seem so clever, when clever turns out to be something simpler, and why befriending them is a bad idea. In this episode, you'll hear about: The crow named Hugo, and what his flock started saying once he was gone Why a walnut dropped at a red light may be less clever than it looks What a goose's heartbeat reveals about how birds feel All audio, video, and images in this episode are either original to Okay, But...

Okay, but is the lyrebird a liar?
E45. Lyrebirds can copy a chainsaw, a car alarm and a camera shutter, so it is easy to call them liars. Dr. Anastasia Dalziell of Western Sydney University has spent years recording them in the wild, and she explains what the famous Attenborough clip left out and some of the most surprising evolutionary reasons for mimicry. In this episode, you'll hear about: Why a female lyrebird starts sounding like an eagle when you get too close to her nest What a male does when the female he has been courting tries to walk away The other lyrebird, and the hooked rainforest vine it plays like an instrument All audio, video, and images in this episode are either original to Okay, But...

Okay, but what's threatening the apex predators of the sky?
E44. An adult eagle has no natural predators, so why are birds of prey declining? Dr. Todd Katzner, a wildlife biologist with the U.S. Geological Survey, explains the surprising dangers facing golden eagles and their kin, from spinning wind turbines to a threat small enough to fit on a grain of rice.

Okay, but what happens when a bird gets sick?
E42. Birds get sick too, and a lot of what happens next looks surprisingly familiar. Dr. Andrea Townsend of Hamilton College has spent two decades following American crows through outbreaks, and she walks Scott through what illness really does to a bird, from the family it belongs to down to the clever brain it depends on. In this episode, you'll hear about: The surprising way crows choose their partners, and what it costs them when disease comes around What a stomach bug does to one of the cleverest birds you'll ever meet Why going it alone can be the riskier move while a virus is spreading All audio, video, and images in this episode are either original to Okay, But...

Okay, but griffins, and ligers, and birds, oh my!
E41. Centaurs, mermaids, minotaurs: we have been inventing creatures that are two things at once for as long as we have told stories. Birds do it for real. Dr. Glaucia Del-Rio of the Florida Museum of Natural History studies two Amazonian antbirds that meet where a river runs out, and what their offspring say about where one species ends. In this episode, you'll hear about: Why a river can be an impossible barrier for a bird with perfectly good wings, and what researchers found when they carried birds out into the middle of one and let go How to spot a hybrid antbird at a glance, once you know which colors belong to which parent The German-Brazilian ornithologist an all-women expedition was named for, and the injury she dealt with herself, a long way from any hospital All audio, video, and images in this episode are either original to Okay, But...

Okay, but... cranes!
E40. There are only 15 crane species on the planet, and 11 of them are in trouble. Dr. Andy Caven, Director of Central Flyway Programs for the International Crane Foundation, has spent his career on two of them: the sandhill cranes that pour into one stretch of Nebraska's Platte River every spring, and the whooping crane, which came back from the edge and is still nowhere near safe. Scott asks him what it actually takes to keep a bird like that on the landscape, and the answer runs through soggy grassland, private ranches, and one river worth fighting over. In this episode, you'll hear about: The number Andy gives for how many cranes stand on that stretch of river, which Scott makes him say twice How a bird that was down to a couple of dozen individuals ended up stopping a dam What a wet meadow is, and why one is so much easier to lose than to build back All audio, video, and images in this episode are either original to Okay, But...

Okay, but why does that bird look so rough?
E39. Every August the questions start: there is a cardinal at the feeder with no head feathers, and it looks terrible. Nothing is wrong with it. It is molting, which every bird does at least every year. Dr. Ryan Terrill of the San Diego Natural History Museum studies what a feather endures over a year and what it takes to replace one, and he makes the case that the few weeks a bird spends looking its worst may be the most consequential weeks it has. In this episode, you'll hear about: Why the cardinal at your feeder in late summer looks like it lost a fight What a bird quietly gives up during the weeks it is growing new feathers The hundreds of miles some birds fly for the sake of a new set of feathers All audio, video, and images in this episode are either original to Okay, But...

Okay, but what's up with feathers?
E38. You have pulled one out of a jacket sleeve at a bad angle, picked one up on a walk, and you are almost certainly within arm's reach of a few thousand of them right now. Dr. Cody Limber, who recently finished his PhD at Yale, spent it taking growing feathers apart one cell at a time to find out what they are actually made of. A feather is not a fancy scale, it does not grow the way you would guess, and after all this time nobody can say what the first ones were for. In this episode, you'll hear about: The strangest things growing out of birds, and which of them actually count as feathers What a feather is actually made of, once you smash one into individual cells and read what every cell was doing What a feather actually is, whether it is alive or dead, how it is put together, and the coordination that color and pattern demand All audio, video, and images in this episode are either original to Okay, But...

Okay, but does age bring Wisdom?
E37. A bird called Wisdom was banded on Midway Atoll in 1956 and is still laying eggs today, which makes her at least 75 and the oldest known wild bird on the planet. She has also outlived the man who banded her, and most of the scientists who tracked her since. Dr. Etienne Rouby studies long-lived seabirds at the Institute of Arctic and Alpine Research at CU Boulder, working with data from the French sub-Antarctic islands where wandering albatross have been followed for more than half a century. Scott asks him what you can learn from a bird that will outlast your career, your funding, and possibly your field station. In this episode you'll hear about: What a fledgling albatross does for the first five years of its life, and why nobody really knows The fishing gear change that pulled a colony back from the brink, and how long it took to see it working Why a very good year for female albatross is a very bad year for the males All audio, video, and images in this episode are either original to Okay, But...

Okay, but do hummingbirds ever chill?
E36. Hummingbirds run one of the fastest metabolisms of any animal with a backbone, which is why we picture them as permanently buzzing. Scott sits down with Dr. Anusha Shankar, assistant professor at the Tata Institute of Fundamental Research, who studies how hummingbirds budget energy in a world that keeps moving the goalposts. It turns out the blur at your feeder is the exception, not the rule. In this episode you'll hear about: Why the same bird might spend three hours a day flying, or thirteen, depending entirely on what the flowers are doing What happens overnight when a hummingbird lets itself go cold, and how long it takes to come back Seven months in the Ecuadorian cloud forest, and the hummingbirds that sat on the nets and waited Plus: the doubly labeled water method, a sugar concentration threshold you can taste-test at your own feeder at your own risk, and the reason Anusha gets called the hummingbird pee person.

Okay, but what's the deal with Darwin's finches?
E35. Eighteen species of small brown bird on a pile of volcanic rock have taught us more about how evolution actually works than almost anything else on Earth. Not because Darwin figured them out. He didn't. Because a handful of scientists went back, banded every bird on one island, and watched it happen in real time. Scott heads to the Galapagos with Dr. Erik Enbody, Assistant Professor of Computational Biology at Cornell University, to find out how one ancestor became eighteen, why the beak is the only thing worth looking at, and what happens when species that aren't supposed to interbreed start swapping genes anyway. In this episode you'll hear about: The island so small you can band every bird on it, and the drought that killed almost all of them One gene that explains 40% of beak size, when nothing in human height explains even 1% The finch that does something mind-blowingly villainous and what it says about how far evolution will go All audio, video, and images in this episode are either original to Okay, But...

Okay, but what's the deal with nests?
E34. Not all birds build one, but for the ones that do, a nest has a single job and a shockingly wide range of ways to get it done. Dr. Vanya Rohwer, Curator of Birds and Mammals at the Cornell University Museum of Vertebrates, joins Scott to walk the far end of that spectrum, from nests made entirely of spit to a colony structure heavy enough to snap the tree it sits in. In this episode you'll hear about: The complete and comical inventory of one hamerkop nest, read aloud, contents included What a bird does when you hand it a nest somebody else already built Why a shed snakeskin in a tree cavity is a calculated decoration New episodes every Thursday.

Okay, but how do birds handle a heatwave?
E33. When the air temperature climbs past a bird's own body temperature, staying cool stops being free and starts to cost them water they may not have. Dr. Blair Wolf, University of New Mexico, has spent his career studying how desert birds survive heat that should kill them, and what happens when it finally gets too hot. In this episode you'll hear about: Why some backyard birds can shrug off oven-like temperatures while others just a few feet away don't make it The strange, water-saving trick birds use to dump heat without a single drop of sweat What the birds dying in these heatwaves are trying to tell us about what's coming All audio, video, and images in this episode are either original to Okay, But...

Okay, but how does wildfire smoke impact birds?
E32. Wildfire smoke is blanketing more of the map every year, and it turns out a smoky sky changes everything for birds, from how they breathe to whether we can find them at all. Dr. Olivia Sanderfoot, Research Scientist at the Cornell Lab of Ornithology, is back to walk Scott through what all that haze is doing to the birds living in it. In this episode: Birds don't breathe the way we do, and that single fact shapes everything about how smoke hits them Stay, shift, or go: the framework for what a bird actually does when the air turns toxic When the birds go quiet, it isn't always because they left Data collection for Project Phoenix is open now through the end of November.

Okay, but is the dawn chorus getting quieter?
E30. That wall of birdsong outside your window at sunrise has a name, a structure, and a surprising amount of drama. This week Scott talks with Dr. Dan Mennill, a professor at the University of Windsor who wires whole forests with microphones to eavesdrop on the entire neighborhood at once, about what the dawn chorus is actually for, and what it means when it starts to thin out. In this episode: Why dawn, why so loud, and who gets to sing first (hint: it's not about who's the best singer) What 16 microphones and kilometers of cable revealed about birds negotiating in real time What happened when one field site went quiet, and why that quiet is louder than it sounds Listen now, then tell us what your morning chorus sounds like.

Okay, but what's it like as a bird at the top of the world?
E29. Standing at 11,000 feet, lungs burning, Scott watched birds go about their afternoon in the exact thin air that had nearly taken him out. This week he sits down with Dr. Chris Witt, evolutionary biologist at the University of New Mexico and curator of birds at the Museum of Southwestern Biology, who has spent his career figuring out how birds make a living in the thinnest air on Earth. From the hummingbird blood that rewrites itself to match a mountainside to a five-pound coot that has no business existing, this one is about the birds thriving where our bodies would quit. In this episode: Why a single Andean slope can stack dozens of hummingbird species right on top of each other, each locked to its own band of elevation How the same oxygen-grabbing protein keeps evolving the same way, over and over, in a pattern so predictable it runs in reverse The record-holders pulling off things up high that sound like they shouldn't be possible Chris doesn't just tell us about these birds, he shows us, so you may want to watch this one.
