Buzz Blossom & Squeak — Be a Neighborhood Naturalist

My friend and I were out at our local federal marsh when we spotted brown-headed cowbirds, a black-billed cuckoo, and a yellow-billed cuckoo — all in the same outing. Three birds with three very different levels of commitment to the same strategy: letting someone else raise your kids. That’s the whole episode right there.

The Spectrum of Commitment. Not all brood parasites operate the same way. The brown-headed cowbird is all-in — she never builds a nest, never incubates an egg, never raises a chick. Her entire reproductive strategy is to find other birds’ nests, drop an egg, and leav...

That bird that acts like it owns your entire backyard? It probably does — and it has good reasons for the attitude. While camping last month, I watched a string of bird fights break out around my campsite, and it got me wondering: what are they actually fighting about? It turns out bird aggression isn’t random at all. It follows rules, and once you know what to look for, you’ll start seeing the logic everywhere.

Fighting is expensive, so it’s never random. Conflict costs energy and risks injury, and an injured bird doesn’t survive as well. T...

Nobody loves the possum. That’s kind of the point.

The hissing, the drooling, the naked scaly tail, the teeth — all fifty of them — and the dramatic habit of passing out and smelling like death when startled. None of this is doing the possum any favors in the public opinion department. But here’s what most people don’t know: that possumwandering through your backyard at night may be one of the best things for your family’s health that you’re never going to think to thank.

I’m making the case for the possum today. St...

If the Appalachians are ancient, rounded, and quiet — worn down by hundreds of millions of years — then what are the Rockies? The answer is: still under construction. This episode picks up where the eastern geography series left off, and heads west into some of the most dramatic, geologically active, and ecologically distinct landscapes on the continent.

Young Mountains and the Rain Shadow That Made the West

The Rocky Mountains are young by geological standards — sharp, dramatic, still rising. Unlike the Appalachians, they haven’t been worn down yet. The Cascades and Sierra Nevadas do something remarkab...

North America doesn't just look remarkable — it is remarkable, and not in a flag-waving way. In this episode of Buzz, Blossom & Squeak, I want to take you on a deep-time journey across the continent and show you how the landscape beneath your feet was shaped by forces that most of us never think about. This is the older history, written in rock, ice, and river — and you can read it in everything from the Great Lakes to the path of a migrating shorebird.

Last week on a camping trip, I had three moments that made me laugh out loud — and then sent me down a rabbit hole about one of nature's most entertaining and overlooked stories. A young downy woodpecker was earnestly pecking a metal pole. A juvenile blue jay locked eyes with me and immediately fled in apparent horror. And on a snag in the woods, a baby barred owl stood hollering for its mother like a very indignant toddler. None of them knew what they were doing yet. And that, it turns out, is exactly the point.

In July 2023, a volunteer doing routine piping plover counts at a Wisconsin wildlife area saw a flash of pink out of the corner of his eye. He stopped. He looked again. He started making phone calls. What he was looking at was a roseate spoonbill — a large, flamingo-pink wading bird with a spatula-shaped bill — last confirmed in the state in 1845. Within days, birders were driving from hundreds of miles away, fifty people showing up on a Saturday just to stand at the edge of a wetland and look at a bird that had no business being there.

Why does the sky turn green when a tornado is coming? Why do storm clouds go black? And what does a 19th-century volcanic eruption in Indonesia have to do with one of the most famous paintings in the world? In this episode of Buzz, Blossom & Squeak, we finish our spectrometry series by bringing it closest to home — reading the colors of the sky itself, and learning what they’re telling us.

The Blue Sky: Our Baseline

A clear blue sky is the result of Rayleigh scattering — a process identified by British physicist Lord Rayleigh in the 19...

Why is Lake Superior almost black on a stormy day and impossibly blue on a calm one? Why does the Caribbean look turquoise when it's made of the same H2O? And what's happening when glacier ice glows that eerie deep blue inside a crevasse? Water doesn't have a color the way a cardinal has red feathers. What we see when we look at water is physics in action — selective absorption, light scattering, depth, biology, and the geometry of the sun. In this episode we break down exactly how it works.

Why Pure Water Is Blue at Al...

We've never touched Mars. We've never scooped up Pluto's frost or sifted through Jupiter's cloud layers. And yet scientists can describe the chemistry of every planet in our solar system with remarkable precision. This episode is about how that's possible — and why the colors you see when you look up at the night sky are some of the most information-rich things in the universe.

The Philosopher Who Said It Was Impossible In 1835, French philosopher Auguste Comte declared that the physical composition of stars and distant worlds would forever lie beyond human knowledge. Within 25 years, he had been pr...

What if you could know what something is made of — without ever touching it? That's not science fiction. It's spectrometry, and it's one of the most quietly extraordinary tools in all of science. In this first episode of a short series, we explore how light carries chemical fingerprints, what a high school flame test has in common with detecting helium on the sun, and why my dad's aircraft engine has everything to do with this story.

Spring doesn't arrive in a single moment — it arrives in layers, and phenology is the science of noticing the order. There's a name for what farmers, hunters, and naturalists have practiced for centuries: tracking when nature shows up. And it turns out you can start doing it right now, with nothing more than a notebook.

What Phenology Is

Phenology is the study of cyclic and seasonal natural events — when the first flower blooms, when the first frog calls, when ice leaves the lake. The word comes from the Greek for 'to appear.' It's one of t...

Duck season is here — and ducks are confusing. If you've ever stood at the edge of a pond going completely blank while trying to name what you're looking at, this episode is for you. I'm launching a new series called Birds That Fool You, and we're starting with ducks: how to build a reliable ID strategy and how to sort out the most commonly confused pairs.

Color Is a Trap — Shape Is Reliable

Most people lead with color when identifying ducks. But color changes by season, by sex, and by lighting conditions. Shape doesn't lie — a duck...

You've heard the dawn chorus — but have you heard the dusk chorus? Step outside at sunset and a whole different world comes alive. In this episode, Jill heads out to a Wisconsin oak savanna just before dark and witnesses something spectacular: the American Woodcock sky dance, the haunting winnowing of a Wilson's Snipe, and eight woodcocks performing courtship displays just feet away. Best of all, neither bird makes its sound with its voice — it's all in the feathers. We also cover sandhill cranes bugling into the marsh at sunset, Whip-poor-wills and Common Nighthawks (the night hunters of the insect worl...

Have you ever woken up at five in the morning, stepped outside into the cold and the dark, and heard a single bird start to sing — and then another, and then another, until the whole world seemed to be answering? That's the dawn chorus. And once you've really heard it, you'll never take a quiet morning for granted again.

What Is the Dawn Chorus?

The dawn chorus is a surge of bird song that builds in the 30 to 90 minutes around sunrise, peaking in spring when birds are establishing territory and finding mates. It happens on ev...

Spring fever is real — and it turns out every creature in the natural world has it too. In this episode I'm exploring the very first thing each animal does the moment winter releases its grip. From frogsicles thawing in vernal ponds to bumblebee queens hunting for a home underground, nature wastes absolutely no time.

Frogsicles and Spring Peepers

Wood frogs freeze solid over winter — no heartbeat, no breathing, just ice crystals in their body held together by glucose flooding from the liver. When they thaw, the first thing they do is head straight for a vern...

Step outside with me for a minute. The grass is still brown and undecided. There are patches of snow on the north side of the fence. The ground is soft on top but frozen just a few inches down. Nothing looks alive — but it really, truly is. Somewhere near your foundation, by the mailbox, wherever the snow melted first, something is already blooming. And something with wings is already looking for it. This episode is about those bold, easy-to-miss first flowers of spring, and the equally bold creatures that depend on them.

Look Up: The Trees Are Al...

I walk past feathers all the time — on the trail, in my yard, floating across the floor when my bird molts — and I'll be honest, I never gave them a second thought. But when you actually stop and look at what a feather is, you realize you've been walking past one of the most complex, precisely engineered structures in the entire animal kingdom. Today we're getting into all of it, and I promise you won't look at feathers the same way again.

Feathers Are Tiny, Interlocking Zippers A feather isn't just a fancy piece of fluff — it's a shaf...

Have you ever watched a dog eat something off the ground and thought — I would be in the hospital right now? Or stared at a koala stuffing eucalyptus leaves into its face and wondered how that's even possible? Today I'm digging into one of those questions that just sits with you — why can animals eat things we simply can't? The answer is genuinely fascinating, and once you understand it, you'll see the animals in your backyard in a completely different way.

How did watching the sky turn into the calendar on the wall and the clock we check every day? This episode explores how ancient sky observations evolved into the structured systems of time we now take for granted.

⏳ Time Before Clocks

Long before digital watches and printed planners, humans looked to the sky. The rising and setting of the sun, the phases of the moon, and the shifting constellations provided the first reliable markers of time. While animals still follow light, temperature, and seasonal cues, humans began translating those natural cycles into numbers and systems.
