Okay, But... Birds

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...

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. In this episode, you'll hear about: Why an eagle that can clearly see a wind turbine still flies i...

E43. For millions of years, South America’s top predators weren’t cats or bears. They were birds, some taller than a person. Paleontologist Dr. Federico "Dino" Degrange of the Universidad Nacional de Córdoba joins us to ask whether terror birds really earned their name. In this episode, you'll hear about: The surprising weapon a terror bird actually used to bring down its prey What left bite marks...

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 p...

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 i...

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...

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...

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 g...

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 Fr...

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....

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 Comput...

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 he...

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 ove...

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 tha...

E31. If a bird sings a phrase worthy of Beethoven, is that music, or just biology in a nice outfit? Dr. Hollis Taylor, a violinist, composer, and ornithologist, has spent more than two decades recording and transcribing the songs of the Pied Butcherbird, an Australian songbird whose vocal life keeps blurring that line. In this episode: How a single pied butcherbird can sing for seven hours through...

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:...

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...

E28. A bird's brain is the most expensive thing it owns, and evolution doesn't hand one out for free. Dr. Carlos Botero , Associate Professor at the University of Texas at Austin, has spent a decade tracing what variable, unforgiving environments actually do to bird cognition, and the answer flips a lot of conventional wisdom on its head. In this episode: Why the harshest places on Earth produce t...

E27. They’ve been called "rats with wings," but pigeons are actually elite athletes, historical icons, and evolutionary marvels. Scott chats with Dr. Elizabeth Carlen , a postdoc at the Living Earth Collaborative at Washington University in St. Louis, to look past the common stereotypes and uncover the remarkable biology of the Rock Pigeon. In this episode, you’ll hear about: The deep historical b...

E26. We borrowed a phrase from human dating and tried to pin it on birds. Turns out they never needed the rulebook. Dr. Wenfei Tong , biologist and author of Bird Love , joins Scott to unpack what bird partnerships actually look like once you stop projecting our scripts onto them, from females who run the territory to males who guard their paternity in deeply weird ways. In this episode you'll hea...

E25. The blue-footed booby has become an internet personality: cartoon feet, a goofy strut, a name that practically begs to be a punchline. But Scott sat down with Dr. Carlos Zavalaga, Universidad Científica del Sur, and one of the people who first taught him how to study seabirds in Peru, and the "fool" reputation falls apart fast. Get a booby in the air or underwater and you're watching one of t...

E24. Flight is the thing we associate most with birds, so what does it mean when a lineage gives it up? Dr. Scott Edwards, Harvard, joins Scott to unpack how flightlessness evolves, why it keeps happening across the bird family tree, and what the genome reveals about how a bird loses the ability to fly. In this episode you'll hear about: How losing flight reshapes a bird's body, from feathers to f...

E23. Across sub-Saharan Africa, wild birds and people work together to find honey. No taming, no breeding, no domestication… just a partnership thousands of years in the making. Behavioral ecologist Dr. Jessica van der Wal, FitzPatrick Institute of African Ornithology, joins Scott to unpack what's actually happening when a honey hunter calls and a greater honeyguide answers. In this episode you'll...

E22. Folklore says birds know a storm is coming before we do. Scott talks with Dr. Gunnar Kramer, Iowa State University, about what's actually happening when a tiny warbler decides it's time to fly, or time to bail. In this episode: Why the question itself might be slightly wrong, and what's really going on inside that bird A storm, some missing warblers, and a discovery nobody set out to make Wha...

E21. We're talking sense and scents with Dr. Danielle Whittaker, Oregon State, and author of The Secret Perfume of Birds , who spent a decade unraveling a 200-year-old myth that started with John James Audubon and a dead pig under a bush. In this episode: The bird that smells like a fresh-baked sugar cookie Why preen oil is a dating profile written in chemistry, and how seabirds use the same chemi...
