E11. Bird vision isn’t just “better than ours,” It’s operating in a different color space, including ultraviolet. In Host Dr. Scott Taylor is joined by Dr. Allison Shultz, Associate Curator at the Natural History Museum of Los Angeles County, to break down what birds can actually see, how scientists measure color in the real world, and why feather color is one of evolution’s most powerful (and misunderstood) tools. In this episode, you’ll hear about: How birds see a whole extra dimension of color (including UV) and why we can’t truly experience “bird vision” without the biology to match How feathers make color through pigments and nano-structures How studying bird color is changing fast, from spectrophotometers to UV-capable cameras, plus why female coloration and “dirty birds” are reshaping what we think we know All audio, video, and images in this episode are either original to Okay, But...

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...

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 into one How a hunter's choice of bullet ends up inside an eagle The flap count that tells a vulture whether to risk crossing the sea All audio, video, and images in this episode are either original to Okay, But...

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 on one of the biggest terror birds ever found Why the last terror bird standing was one of the smallest All audio, video, and images in this episode are either original to Okay, But...

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...

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...
