What do feathers, toothless beaks, and a 66-million-year-old asteroid have in common? Paleontologist Dr. Daniel Field, University of Cambridge, joins Scott to unpack how birds evolved from dinosaurs, and why defining "bird" is trickier than you think.

In this episode you'll hear about:

1. Why Archaeopteryx had half the features of a modern bird and lacked the other half, and what that tells us about 150 million years of evolution
2. The "Wonderchicken," a tiny fossil from the border of Belgium and the Netherlands that rewrote what we know about birds surviving the asteroid impact
3. How micro CT scanning lets scientists digitally peer inside rocks to study fossils at micron scale without ever touching them

Some birds skip having their own families and spend years helping raise their siblings instead. It sounds like altruism, but it's probably more complicated than that. In this episode, host Dr. Scott Taylor is joined by Dr. Nancy Chen, UCLA, to unpack the notion that it takes a village to raise a child chick.

In this episode, you'll hear about:

1. Why some birds spend years as unpaid helpers before starting families of their own
2. What the Florida Scrub-Jay's 50-year study at Archbold Biological Station revealed about cooperative breeding
3. Whether helping your siblings is really altruism or just evolution doing it’s thing

Winter isn’t just “cold” for a bird, it’s a nightly survival math problem: generate enough heat, lose as little as possible, and don’t get eaten while you’re fueling up. In this episode, host Dr. Scott Taylor is joined by Dr. Maria Stager, UMass Amherst, to break down the clever physiology and weird little behaviors that let birds ride out freezing temps, from icy duck feet to “feather puffball” mode to energy-saving torpor.

In this episode, you’ll hear about:

1. How birds keep their feet from freezing
2. How feathers and shivering muscles act like a built-in winter jacket
3. How birds manage energy overnight, including fat, roosting, and torpor

E11: Okay, but why is a bird’s world more colorful?

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:

1. 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
2. How feathers make color through pigments and nano-structures
3. 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

Seasons used to feel predictable. Winter showed up, spring arrived on cue, and birds could run their annual schedules like clockwork. But now the timing is weird: early heat, late snow, shifting green-up, and food peaks that don’t always line up. In this episode, host Dr. Scott Taylor is joined by Dr. Morgan Tingley, Professor of Ecology and Evolutionary Biology at UCLA, to unpack what “keeping up” with climate change actually means for birds, how scientists measure it, and what gives birds a fighting chance on a rapidly warming planet.

In this episode, you’ll hear about:

1. How birds “keep up” by shifting their ranges to cooler places, and the clearest real-world examples of birds already moving north
2. Why the story is more complicated than “north and uphill,” including microclimates, precipitation shifts, and the messy reality of predicting habitat changes
3. The full bird toolkit for coping with climate change: movement, timing (phenology), and even shrinking body size over generations, plus what we can do right now that actually helps birds

Birdwatching, birding, twitching… whatever you call it, it’s got everything: quests, rare finds, elaborate gear, a sprawling universe of characters, and a deeply committed fandom. Sound familiar? In this episode, host Dr. Scott Taylor is joined by NYT best-selling author and Pulitzer Prize-winning journalist Ed Yong to explore how modern birding became more accessible than ever (hello, Merlin and eBird), why it can feel like an open-world RPG, and what the Pokémon comparison misses.

In this episode, you’ll hear about:

1. How Ed Yong fell into birding after moving to Oakland, and why the “virtuous cycle” of noticing more makes you want to keep looking
2. Why Merlin is more than an ID tool, and how eBird functions like “the last good social network” without clout-chasing
3. The ethics and culture of birding today, from playback debates to the weird social dynamics of rare sightings, plus why birding is such a powerful way to connect to place, community, and change

Cities can look like a concrete nightmare for wildlife… yet some birds are absolutely crushing it, while others vanish. In this episode of Okay, But... Birds, host Dr. Scott Taylor is joined by Dr. Fran Bonier, Professor at Queen’s University, to unpack what “urban birds” really are, why cities create winners and losers, and what it actually costs a bird to live the high-rise life.

In this episode, you’ll hear about:

1. Which birds tend to become “city birds,” and why some species thrive in urban spaces while others disappear
2. The concrete benefits and hidden costs of city living, plus the traits that predict an urban “winner”
3. How scientists test whether birds are adapting and learning fast vs. being filtered by city conditions, and what the biology says about stress in urban birds

Every bird song you’ve ever heard on a hike, through an open window, or sampled in a nature documentary has a story behind it. In this episode, host Dr. Scott Taylor is joined by Linda Macaulay, Chairman of the Board of the Cornell Lab of Ornithology, to explore how bird sounds get recorded, preserved, and shared with the world, and why audio might be one of the most powerful tools we have for understanding and protecting birds. And yes, it’s THAT Macaulay; the one with the library named after her. Casual.

In this episode, you’ll hear about:

1. How Linda helped build the world’s bird sound library and why it matters
2. What it takes to record a clean bird vocalization in the wild and the even wilder stories behind the scenes
3. The role of the Macaulay Library and what’s next for apps like Merlin
