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...

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...

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 feathersWhat a feather is actually made of, once you smash one into individual cells and read what every cell was doingWhat a feather actually is, whether it is alive or dead, how it is put together, and the coordination that color and pattern demandAll audio, video, and images in this episode are either original to Okay, But...

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 knowsThe fishing gear change that pulled a colony back from the brink, and how long it took to see it workingWhy a very good year for female albatross is a very bad year for the malesAll audio, video, and images in this episode are either original to Okay, But...

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 doingWhat happens overnight when a hummingbird lets itself go cold, and how long it takes to come backSeven months in the Ecuadorian cloud forest, and the hummingbirds that sat on the nets and waitedPlus: 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.The "snoring" hummingbird video Scott and Anusha discuss: https://www.youtube.com/watch?v=_uEfmQt34NcAll audio, video, and images in this episode are either original to Okay, But...

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 themOne 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 goAll audio, video, and images in this episode are either original to Okay, But...

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 includedWhat a bird does when you hand it a nest somebody else already builtWhy a shed snakeskin in a tree cavity is a calculated decorationNew episodes every Thursday.

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 itThe strange, water-saving trick birds use to dump heat without a single drop of sweatWhat the birds dying in these heatwaves are trying to tell us about what's comingAll audio, video, and images in this episode are either original to Okay, But...
