433 – Heartbeats and Birds

My heart raced as I reached my hand into the bag. What if I broke them? What if I let them escape? Then my fingers found a familiar grip, and before I knew it, I was holding this bird just like I had the warbler. Now that I was the bander and not just the releaser, the vibration of their heart felt different. Their safety was in my hands. My own heart slowed, and I took a steadying breath.

Maneuvering the veery so that I could grip their right leg in my left thumb and forefinger, I slipped the open band over their leg. Now they were ready to contribute to science!

“This bird will be forever connected to you,” Jim reminded me after we’d sent the veery flying back into the brush. My heart fluttered happily.

432 – The Making of a Master Naturalist

The sound of boots crunching on sandy sediments and excited chatter filled the air. The first day of our Wisconsin Master Naturalist training had begun, and twenty people from all walks of life were eager to learn about the ecology of the Northwoods. Over the next five days, these participants would be exploring sites all over Bayfield County, and learning from experts across multiple natural resource fields. Our goal was not to instantly train experts in Northwoods ecology, but rather to spark curiosity and connection with the natural world. Whether coming from a natural resource background themselves, or simply wanting to learn more about nature, our participants were eager to dive into the knowledge of our experts. And we were jumping right into the geology of the Northwoods at our first field trip location–an esker left by the glaciers around 11,000 years ago.

431 – Preserving the Legacy of Black Ash

Dappled light, mosquitoes, and the roar of a chainsaw filled the humid air on a morning in early June. Guided by skilled hands, the blade sliced through pale wood. Lacey green leaves trembled against the blue sky before tipping toward a gap in the canopy, brushing past the twigs of neighbors, and easing quietly onto the earth exactly where the feller intended. If a black ash tree falls in the forest, must it land with a crash?

Deep in the woods east of Lake Namakagon, I’d gathered a small team of volunteers on an urgent mission.

430 – Summer Blooms with Lois Nestel

While staying in Boulder Junction, Wis. to take a Wilderness First Responder course last week, I made time for a bike ride on the Heart of Vilas County Bike Trail. This wonderfully curvy, scenic, paved trail is a favorite of mine. At this junction between spring and summer, I delighted in the profusion of flowers.

Lois Nestel, the Museum’s first naturalist and director, might not have joined me on a bike ride, but I know I would have loved to walk attentively through the woods with her. This week, I’d like to share her description of the residents of woods and fields as summer begins to bloom. Slow down a minute with me, we’ll smell the roses, and I think you’ll find it rewarding.

429 – Fossil Explorations

I sat on the tan, dusty ground of the quarry in north central Iowa, fingers grasping at the shell that lay halfway buried in the chalky clay and limestone. Wiggling it back and forth, I gently pulled it up from the ground that it had been resting in for millions of years. The ridged shell was almost perfectly intact, painting me a detailed picture of what the animal looked like. I had found a brachiopod fossil, a marine invertebrate who used to live in the warm, shallow sea of the Devonian Period, roughly 380 million years ago. As I sat examining my find, I couldn’t help but think about how special it is to find something so ancient, to hold the remnants of their life in my hand, and glimpse what life on Earth was like millions of years ago.

428 – Spring Explodes in the Northwoods

In just the last week or two, new life has exploded in the Northwoods. To my brain, it feels like a burst of fireworks. Instead of embers sparkling in the darkness, there’s been a surge of colorful blossoms, an eruption of vibrant baby leaves, a cacophony of birdsong, and a buzz of movement everywhere I look.

427 – Balsam Poplar: Tree of the Far North

The shiny resin on balsam poplar buds turns to airborne molecules during spring leaf-out. Those molecules contain a myriad of chemicals that are useful to the tree — and beneficial to us! Thriving in the far north — farther than any other broadleaf tree in North America — balsam poplar is poised to make drastic changes to the tundra as summer temperatures warm.

426 – A Prairie-Dweller Moves North

A lump of gray fur in the middle of the trail pulled us up short. The small mammal was about the size of a gray squirrel, but with cute, round ears tucked below their silhouette. I’d never seen a Franklin’s ground squirrel before! On various websites I read that these are a species of tallgrass prairies, although they’ve declined as the prairies have declined. In the southeastern part of their range the squirrels are barely hanging on in grassy roadsides and railroad right-of-ways—the same places where a few native plants have escaped the plow. Several sources suggested that they belong only in the southern and western portions of Minnesota.

425 – The Trill of a Pine Warbler

My companion gasped in the middle of a sentence as a pine warbler darted over my head and landed on rough spruce bark a few feet way. Then he swooped to a rock wall and paused mid-hop to belt out a trill. We watched his stout beak open and his white wing bars vibrate with the effort. Pine warblers are aptly named, as they are rarely spotted anywhere but in pine trees.

424 – A Torrent of Mis-Named Birds

First, we squinted, then we peered through binoculars, and finally I zoomed in with my camera to make sense of the dark shapes. The ducks had a funny conehead and a gracefully swooped patch of gray on their side. The pale ring around their dark beak was the most distinctive character. I’m not good at waterfowl, so I wracked my brain for a likely ID…were they ring-billed ducks? That would be logical. But no, a quick peek through the Merlin app’s helpful photos confirmed that these were ring-necked ducks. Huh?

423 – A Shorebird in the Forest

Just having returned from a week of birdwatching on the Atlantic coast, the plump-bodied, long-billed silhouette of this “hokumpoke” reminded us of the sanderlings, dunlins, and willets we’d watched scurry ahead of the waves. It’s a strange fact that despite their preference for damp thickets instead of beaches, woodcocks are the most numerous sandpiper in North America.

422 – The Heron’s Plan

The fish appeared to be a striped mullet, a common species of coastal waters. At first, the mullet appeared to be winning. They flopped and slipped father through the herons bill, surely about to escape the final grip on their head. Then the heron’s plan became apparent. All the movement was maneuvering the fish’s head to aim aerodynamically into the heron’s beak. With one last toss of their head, the fish disappeared.

421 – Sunrise Dancers

It was well before sunrise as we drove into the Namekagon Barrens Wildlife Area and parked the truck. Moving as silently as possible, we grabbed our chairs, a much needed thermos of coffee, and started the walk to the viewing blind, its white silhouette barely visible in the distance. Once to the blind, we crawled inside, set up our chairs, and unclipped the blinds windows. I stared out into the dark of the early morning, feelings of excitement and anticipation buzzing through me. Afterall, it’s not everyday that I get the chance to watch sharp-tailed grouse dance on their lekking ground.

420 – Spring Cleaning with Turkey Vultures

On the inside, turkey vultures’ intense stomach acids can kill the microbes that cause botulism, anthrax, cholera, tuberculosis, salmonella, and rabies. How appropriate that the birds’ scientific name—Cathartes aura—means “purifying breeze.” Their digestive system is so powerful that it even destroys the DNA of their food. As of March 27, I still haven’t seen a turkey vulture in the Northwoods, but soon they’ll be showing up on the wind and helping us out with a little spring cleaning!

419 – Thrasher Concert

From the top of a leafless oak tree commenced a steady stream of whistles and warbles that sounded as if an entire flock of flickers, vireos, titmice, cardinals, and wood thrushes were all taking turns. Just one robin-sized bird perched there, though. Brown thrashers are “mimics” who increase their repertoire of songs and show off their skills to the ladies by copying from other birds. Across the Southeast are brown thrashers who will soon be migrating north, just a little bit behind the loons. Their concert tour continues! Plan to attend one of their performances at dawn in your local shrubbery.

418 – The Loons of Lake Jocassee

Scientists used to think that almost all our Common Loons spend the winter on salt water. From across the northern lakes, loons migrate to both coasts and the gulf each fall to avoid ice-up. Now we know that more than 100 loons spend each winter on a large freshwater lake in South Carolina. In this relatively small area, it becomes easier to carry out research on loon behavior.

417 – Mushroom Munching Slugs

As mother nature slowly begins to tease us with the occasional warm day, and longer periods of sunlight, I can’t help but dream of warmer days spent exploring outside, underneath the forest canopy. One of my favorite things to do while exploring the forest is to take in the intricacies of the forest floor, and discover the diverse life that inhabits that space. Between the litter layer, growing mosses, and decaying logs, a utopia full of life is waiting to be unearthed.

416 – “Whooo” will we see?

Seeing a moth seemed to signal that evening was coming, and our thoughts turned to owls. Sax-Zim Bog is famous for hosting rare owls. Last year was an incredible irruption year when great gray owls, boreal owls, and snowy owls visited from their homes farther north. This year has been much quieter. A few great gray owls nest here, but lately they’ve been secretive. We’d heard that a northern hawk owl was hunting at the edge of a field on some of the private land that makes up the patchwork of ownership in Sax-Zim Bog Important Bird Area in Northern Minnesota, so off we went!

415 – Peanut Butter Saves the Jay

The Canada jays swooped from the feeding station, back over my head, and disappeared into the forest behind me. Were they taking peanut butter to their chicks? These intrepid birds nest in February and March! That’s one reason their food caches are so important.

414 – Fishers Looking For Love

Early spring is when male fishers travel widely in search of mating opportunities. I often see their tracks in the softening snow as they tour their 9-15 square mile home ranges that overlap the smaller territories of several females.

413 – The Elusive Lynx

I stared open-mouthed in disbelief at the cat crossing the neighborhood street in front of my new house in Silver Bay, MN (I’ll be moving up full time in 2027). Trotting purposefully on long legs, with a body almost three feet long, this was no housecat. “Bobcat!” I exclaimed, eyeing the black tip on their short tail and dark blotches on gray-brown fur. Bobcats are common in Northern Wisconsin where I’ve been living for the past 15 years, and are often spotted around homes and roads, so that was the most likely identification my startled brain could find. 

But as the cat climbed up the pile of dirty snow on the curb and into my neighbor’s yard, the size of their huge, furry feet came into full view. That, along with long black ear tufts visible against the white, confirmed their identity: Canada lynx.

412 – Is the Sun Setting on Evening Grosbeaks?

Evening grosbeaks are colorful members of the finch family. These bright birds travel widely toward the best food sources in movements known as “irruptions.” In 2016, the evening grosbeak was cited as the steepest declining landbird in the continental United States and Canada. Together, networks of scientists and legions of bird-lovers are working to make sure that the Sun isn’t setting on evening grosbeaks.

411 – Stories in the Hemlocks

As my boots crunched and sunk into the snow, the trees were shedding bits of snow that littered their branches, dispatched by the wind. In my attempts to avoid getting showered by falling snow, I found myself walking among scattered giants. Standing next to the old eastern hemlock, staring up at the towering trunk, I began to feel very small as I imagined what this tree has lived through and the things that they have seen. How many generations of songbirds have nested in their branches, or found food in their cones? How many generations of deer, bears, wolves, and other wildlife have they seen treading beneath their branches? How have they seen us change, and do they like what they see? How have they watched the world change around them, as they stand rooted in place?

410 – How Do We Know the Moon

“‘I know the moon,’ said the fox”

My colleague read this title line aloud from a children’s book recently, as part of a staff training. At first, I was just as enchanted with the story as she was. The fox goes on to describe how the Moon is like a rabbit that he can chase across the night. The moth disagrees with the fox, though, as does the owl, the mouse, and the bullfrog. The animals start bickering about who’s right. They decide to visit A Man of Science, and each Being hopes that he will confirm their perspective. But the Man of Science declares that the Moon is made of sand, and nothing more.

I sensed that the author was trying to make some point about how the facts and figures of science are out to squash wonder in the world. How horrible that would be! I realized that the author had constructed a strawman argument by setting up a simplistic imagined opponent that’s easy to knock down. Giving children an incorrect view of science and scientists isn’t going to help them navigate our changing world. It isn’t going to help them to know the Moon.

409 – Why Woodpeckers Don’t Get Concussions

The idea that a woodpecker’s tongue provides cushioning for their brain as it wraps around their skull has come into question. The newest calculations, made with the most accurate modern technology, refute the idea that a woodpecker’s brain is cushioned at all!

Of course, any of these conclusions might be proven wrong or incomplete as scientists discover new information in the future. The beauty of science is that it requires us to be able to change our minds in light of new evidence. One thing that doesn’t need to change is the magic we feel when we watch a great black bird with a flaming topknot spread their broad wings and with a few swooping beats disappear into the forest.

408 – Cute Bits of Camouflage

Brown creepers are cute little bits of camouflage with white bellies. This one moved upward in staccato motions, a bit to the side, around to the back, back to the front, and up some more. Pausing, the bird used their thin, downward-curving bill to explore a bark furrow. Perhaps they had spotted an overwintering insect larvae or antifreeze-protected spider for their lunch. Near the limit of my view out the window, the creeper suddenly launched off the tree and fluttered downward toward another tree trunk, out of sight.

407 – My Friend the Muskrat

As snow continues to blanket the ground, and the plummeting temperatures cause the air to bite at exposed skin, I can’t help but reminisce on warm summer day adventures. One adventure in particular had me exploring local wetlands, those special places where water and land blend together to create exquisite, diverse ecosystems. One wetland gifted me with a memory I won’t soon forget, and reminded me just how beautiful even the simplest experiences in nature are.

406 – Mulling over Mullein

This is the season for lists highlighting our most-listened-to or best-of-whatevers at the end of the year, so I decided to dig into the stats on my Natural Connections blog. To my surprise, the most-read article in 2025 was one I wrote in February of 2016 about a plant called mullein. In August 2025 it spiked in popularity, far above my normal readership. I have no idea why. I recently told someone the story of finding the chickadee-cached seed in the mullein stalk, but I’d forgotten about the rest of the article. It’s fun! And appropriate to this season. So, I hope you enjoy it as much as the 1.24K other readers did, too! Happy New Year! –Emily

405 – The Bohemian Bird

Bohemian waxwings are known for their ability to find a tree full of berries in the middle of nowhere, descend on it en masse, strip every edible fruit from the twigs, and then disappear to their next meal. That’s exactly what they did as I watched.

404 – Wintertime Porcupine

Heading north on Highway 63, the beautiful scenery never fails to keep me entertained as I drive through the picturesque nature of the Northwoods. While my thoughts wandered, a large dark spot high in a distant tree caught my eye. At first, I thought it might be a squirrel drey–a large nest of twigs and leaves built high in a tree. But as I got closer, I realized that it was a porcupine! Once my excitement calmed down, curiosity began to take its place. I began to wonder why exactly this porcupine was high up in the tree on this late fall morning. The answer may lie within the feeding strategies of the North American porcupine.

403 – The Subnivean Zone Returns

As winter’s first snowflakes drifted through the dark, some landed on top of dead plants, fallen leaves, twigs, and other detritus of the forest floor. In many places, snow never fully reached the ground. That was surely true for the protected hideaway of my thermometer. By dawn, it was buried under six inches and counting.

Despite falling temperatures, the relative warmth of the cold rain and the residual heat of summer were still radiating from the soil. At sunrise, when I checked the weather station, the air temp had dropped to 24 degrees Fahrenheit, but the sensor cozied up to the earth under a fresh blanket of snow read 33 degrees. After two winters of thin snow, the Subnivean Zone has returned!

Read all about it in this week’s Natural Connections or listen to the podcast. Find links to both at https://www.cablemuseum.org/connect/ or in our profile.

402 – The Bright Red Warning of Barberry

The arching stems, decorative berries, and warmly hued, persistent fall foliage of barberry, plus the complete lack of deer browse on their twigs, are why they were brought to the U.S. as an ornamental plant in 1875. That was fine, until in the 1980s they started to spread out and displace native plants. Now Japanese barberry is considered invasive in 17 states, including Wisconsin, Minnesota, and Iowa.

A barberry thicket also provides a safe, fox-resistant haven for mice, and a shady, humid home for ticks. Deer ticks feed on mice, who are reservoirs for Lyme disease.

401 – Southward Migration

The shallow water in Northwoods marshes and bays began to crackle with a skim of ice recently, gently reminding everyone that winter is on the way. Ice-up is a firm deadline for many beings who migrate to travel at least a little bit farther south. I got caught up in the flurry of activity and soon found myself in the Mississippi River Flyway swooping around the hills and corners of the Great River Road with other Northerners heading south.

400 – Dowsing for Witch-hazel

Beside the trail stood a spreading shrub with a few rays of sunlight illuminating tiny yellow flowers that looked just like sunbursts themselves. Witch-hazel! The flower-dappled shrub twinkled like a reminder of spring. While they do bloom near Halloween, witch-hazel’s name is probably a misspelling of old English words wicke or wych that meant “lively” and “to bend.” They refer to the use of a forked branch of witch-hazel as a dowsing rod, which purportedly would bend downward to point out a good location to dig a well.

In a bit of reverse-dowsing, rain showers helped me see the leaf, and sun rays helped me see the witch-hazel. On that fall day, I found a deep well of beauty.

399 – Watching Cranes at Crex Meadows

“Turn here, they’re heading north!” I directed my fiancé as we navigated the gravel roads of Crex Meadows Wildlife Area near Grantsburg, WI. We’d spotted a line of sandhill cranes flying through the sunset sky, and were following them toward what we hoped would be a spectacular evening of birdwatching.

398 – Fantastic Fungi

The air shimmered as I walked through the forest, the heavy mists encompassing me in a damp blanket. As my shoes trod on soggy leaves, I took in the quiet serenity of the forest. Many of the trees had begun their annual changing of the colors, painting the canopy in shades of yellow, orange, red and green. Their discarded leaves were already beginning to dot the forest floor in late September. But fallen leaves weren’t the only contributors of color on the ground–the fall mushrooms were popping in the Northwoods.

397 – Butterfly Breezes of Fall

At first, a flutter at the edge of my vision made me think that an autumn leaf had somehow managed to fall half a mile to the middle of the lake. A closer look revealed the dark purple wings of a mourning cloak butterfly. In late September?

Weeks later, a flutter at the edge of my vision caught my attention just in time to watch an autumn leaf come to rest on the ground. Small quaking aspen leaves carpeted the trail in a mosaic of yellow and green. They were evidence of yet another way that a Lepidopteran (butterflies and moths) survives the winter.

Colorful leaves and colorful wings flutter on fall breezes, all getting ready for winter.

396 – Flying Kittens

“Just hold her like this,” Kurt told me. So I carefully nestled my first two fingers into the soft, warm feathers around the neck of this tiny northern saw-whet owl, cradled her soft, warm torso in the palm of my hand, and secured her brown and white wings with my thumb and other fingers. My heart stopped for a moment, but under those soft, warm feathers I could feel her smaller heart racing.

395 – Green Frogs Prepare for Winter

Finally, within sight of the next lake, movement near the toe of my boot startled me almost to the point of disaster.

Big black eyes with golden rims stared up at me from the slope of a rock. Crooked toes gripped the rough surface, and long hind legs braced for a quick escape. The green frog who had jumped out from underneath my boot perched motionless, as if that made them invisible.

394 – The Mystery of Mast Years

Last week I wrote about acorns clattering across my roof. As it turns out, nuts are raining down on many of your roofs, too! Commiserating over the loud, foot-rolling acorns makes me feel like part of an extended community. Are the oaks part of a similar community? And why are they suddenly attacking us with acorns!

Oaks are mast species, which means that all the trees in an area will produce a bumper crop of acorns at the same time, but only every two to five years. From mice to owls to chatting neighbors, oaks, and the mystery of their mast years, are at the center of our Northwoods community.

393 – A Summer of Loon Discovery

The pontoon bobbed in the water as I stepped onto the deck, clutching binoculars and trying to contain my excitement. Since moving to the Northwoods in the middle of winter, I had been waiting for the chance to see a loon, and my chance finally arrived in late May. The sunlight danced across the water as our boat left the dock, and we began our search. It wasn’t long before we spotted the silhouette of a loon off in the distance, and headed for a closer look.
Two large red oak trees reach the edges of their canopies out over the roof of my house. Each fall, they create a racket as acorns drop on the metal roof, tumble down the steep slope, and launch out over the driveway. Some years are worse than others, since oaks are mast trees who will produce a bumper crop in one year, then spend subsequent years rebuilding their stores of nutrients and not producing as many acorns. This is clearly a mast year.

392 – Attack of the Acorns

Crack! Rumble, rumble, rumble. Crack! The sound of hard objects pelting my metal roof shot through my open bedroom window, rousing me from the last wisps of sleep. Then silence. I braced myself as a soft hush of wind drew closer. Crack! The wind triggered a new spatter of noises. The house was under attack—by acorns.

391 – Shades of Rot and Life

(This essay is a chapter from Emily’s third book, Natural Connections3: A Web Endlessly Woven, which will arrive in November 2025!)
In the dim light, under the thick, hardwood canopy of the forest, death was everywhere.
Of course, life was everywhere too.

390 – Mysterious Loon Behavior

We’d only been watching for a few minutes when suddenly one of the loons took off running and flapping down the bay toward the main lake. Huge, webbed feet splashed at the surface. As soon as the first loon rose above the water, the remaining loon followed in a flurry of flapping wings and feet. What had just happened? The group looked around at each other in amazement, feeling lucky to have witnessed this fascinating bit of loon behavior.

389 – A Blue-Spotted Vision

Although the temperature plummeted and rain ran off our jackets, our excitement and determination could not be dampened. Rubber boots tromped over soggy leaf litter, and hands grasped at every fallen log, flipping them over as we searched the forest. The Wild Wonders campers and I were on a mission, seeking out an animal who thrives in rainy conditions–the salamander.

388 – Unexpected Hope

I was just about ready to round up the group and move on from the old quarry when someone exclaimed over a pretty white flower among the weeds. Five luminous petals, each with translucent lines arcing gracefully toward the nectar reservoir in the center, provided the backdrop for a ring of delicate eyelashes tipped with glossy yellow spheres. I could barely believe my eyes! I first met bog star, or marsh grass-of-Parnassus, during my summer in Alaska while assisting with a snowshoe hare study in the Brooks Range. This little beauty captured my imagination immediately.

387 – Further Observations of Forked Fungus Beetles

Guest writer Katherine Woolley is about to start her junior year as an environmental education major at Western Colorado University. This summer, as a Summer Naturalist Intern at the Museum, she taught our Junior Naturalist programs and showed a real talent for finding and appreciating the oddest parts of nature.

I spotted the male first. He was sitting on the highest point of the mushroom shelf like he was the king of the hill. Then I spotted his mate, who to my surprise, looked like she was sitting up. I knelt down and cocked my head to the side to get a better look. For beetles who usually crawl on all six legs, this was an unusual position. Was she laying eggs?

386 – Finding Forked Fungus Beetles

Guest writer Katherine Woolley is about to start her junior year as an environmental education major at Western Colorado University. This summer, as a Summer Naturalist Intern at the Museum, she taught our Junior Naturalist programs and showed a real talent for finding and appreciating the oddest parts of nature.

A walk along the Forest Lodge Nature Trail is never boring. I was reveling in this fact as I took my evening meander through the large trunks of towering trees. To my left, I spotted a shelf fungus clinging to the bark of a half-decayed paper birch stump. Creeping closer to investigate, I squealed with delight. There they were! Two forked fungus beetles were nestled in the corner of their polypore home.

385 – Seeds on the Move

Guest writer Kylie Tatarka is about to start her senior year as an environmental science major at Rochester Institute of Technology. This summer, as a Summer Naturalist Intern at the Museum, she taught our Junior Naturalist programs and spearheaded the creation of the online  “Becoming the Northwoods” exhibit. 

Seeing the aspen-covered ground reminded me of a tree that is more common in my home state of New York, the eastern cottonwood tree, which is a relative of the aspen with similar cotton-tufted seeds. I grew an affection for these trees while leading a seed dispersal hike. With the kids, we discovered examples of seeds that are dispersed by wind, water, animals, gravity, and bursting. Now I’m always on the lookout for plants with interesting methods of seed dispersal.

384 – Boundary Waters Beauty

The Boundary Waters is beautiful, but that’s only part of it. What really keeps people coming back, I believe, is the way this place helps us to challenge ourselves. When you cut out the excess, the superfluous, and the mess, and fit everything necessary for a week or two of life into a single, green pack, life becomes simple. There is an incredible sense of freedom in this knowledge of self-sufficiency. This freedom feels all the more sweet when it comes with manageable challenges and a means to test our mettle.

383- Looking Into the Lives of Dragonflies

Upon spotting the green dragonfly resting close enough for me to capture, I knew I had to try. With my kayak nestled into the grassy bank of the Namekagon River, I snapped a few photos of my target and began to reach my hand out slowly. But when my fingers gently grasped the dragonfly, I was horrified to find that it was squishy rather than the typical hard feeling of an exoskeleton. My hand shot back to my side in an instant, repulsed. My first thought was that the dragonfly was dead and waterlogged.
In the lagoon where decomposition has slowed and organic matter has accumulated over time, a floating mat of Sphagnum moss and sedges holds numerous treasures in a type of wetland called a fen. Treasures I was hunting!

382 – Treasures of the Big Bay Lagoon

The calm waters of Lake Superior glimmered in midday sunshine, and dozens of families enjoyed the sandy beach of Big Bay Town Park on Madeline Island. I hiked past them all, my steps echoing slightly on the boardwalk that winds through pine forest behind the beach.

381 – Hunting For Elk

If an elk calf can make it through their first year, they have a 92 percent chance of surviving each year after that. The DNR is in year two of a three-year effort to understand the survival rates and mortality factors of that first perilous year. Do the young do better where there’s been a recent timber harvest or other disturbance? How important is it for the maternity habitat to have a view? To answer these and other questions, they attempt to locate and deploy a GPS collar on 25 calves as soon as possible each spring.

380 – Canadian Tiger Swallowtails

Something small and bright caught my eye. Stopping mid-stride and mid-conversation, I bent down to look at a small jumble of legs and exoskeletons in the tread of the Ice Age Trail. The yellow mantle behind the head of a black carrion beetle is what I’d noticed first. They are quite striking, even when rooting around in the decaying flesh of a recently dead animal, looking for a place to lay their eggs. The adults eat dead stuff, too, hence the bear hug this one was giving a shiny brown, but unmoving, carcass of a Junebug.

379 – Junebugs and Beetles

378 – Skydancing the Night Away

Excitement and nerves were at an all time high as my car crept down the gravel road, the sun having just slipped below the horizon. I was on the hunt, following clues to lead me to my prize. My treasure was the somewhat elusive American woodcock, and I was hoping to catch a glimpse of their infamous skydance.

377 – Baby Food

Although I often hear their rattling bugle calls echoing across the lake and through my open windows, having cranes nest where I could see them was a new treat. For a few weeks, every warm afternoon found me biking along that stretch of road with my camera at the ready. Each time, the evening sunlight spotlighted the face of a crane on the nest.

376 – The Teachings of Ghost Pipe

Last Sunday I was asked to give the message for the Chequamegon Unitarian Universalist Flower Ceremony. Everyone brought a flower, they were admired in a bouquet, and each person left with a different flower. This symbolized the unique value of each person and the way we came together to create a beautiful bouquet. To illustrate this idea, I chose to talk about ghost pipe (previously named Indian pipe), a plant whom I’ve been puzzling over for a while. In preparing the talk, I realized that I’d learned a lot from ghost pipe.

375 – Wilson’s Warblers on Their Way

Scientist E.O. Wilson’s book Biophilia hypothesized that humans possess an innate tendency to seek connections with nature and other forms of life. He wrote, “To an extent still undervalued in philosophy and religion, our existence depends on this propensity, our spirit is woven from it, hope rises on its currents.”

I watched as the Wilson’s Warbler bounced like popcorn through the narrow, willow-ish leaves of an unknown desert shrub. While this bird was named for a different Wilson, he certainly satisfied E.O. Wilson’s Biophilia.

374 – Networking

I apologize for the weird audio quality this week! I’m traveling — as you’ll hear — and my audio editing program did an update that takes out breath noises, etc, automatically. But that also changes how my voice sounds and seems to reduce enunciation. If it’s too annoying to listen to, you can read the article at: https://cablemuseumnaturalconnections.blogspot.com/ 

373 – Adventures in Porcupine Lake Wilderness

At the trailhead, the woods were set alight by the sunshine reflecting off the melting snow. While my boots crunched down the trail, my eyes wandered to the trees where life was starting to awaken. Lichens, mosses, and mushrooms decorated the bark in a burst of bright greens, yellows and oranges–a welcome sight against the backdrop of the forest.

372 – Lois Nestel’s Sweet Ode to Spring

“What sweet ode shall we write to spring? Soft and tremulous one minute, tempestuous the next, she proffers her gifts with one fair hand and with the other snatches them away.”
–Lois Nestel, Wayside Wanderings II

371 – The Sparrow’s Songs

A faint string of birdsong filtered through closed windows on a recent morning. It was well after dawn, but thick gray clouds made it feel like the Sun had yet to rise. “Song sparrow!” I exclaimed. “They must have arrived overnight!”

370 – The Pulse of a Waking Forest

The grouse drummed again; thumping slowly at first, and then crescendoing into a rapid-fire blur. As his last vibrations dissipated into the still air, another grouse answered from a neighboring territory. The low-frequency sounds are audible from up to a quarter mile away. I’m always amazed by how much I feel their sound instead of hearing it.

369 – Snowshoe Hares Eat Dirt

For three days in the summer of 2018 we worked on this mark-recapture survey along a pipeline access road in the Brooks Range of northern Alaska, gathering data that would help scientists at the nearby Gates of the Arctic National Park estimate snowshoe hare population numbers for this year. Our opinion? The population was high. Almost every trap was full, which meant a delayed lunch, and that sense of relief to find an empty trap.

368 – A Home for Wood Ducks

Listening to a pair of wood ducks explode from a tiny patch of open water in a woodland pond and woo-eek through the woods is a distinctly springtime experience. Wood ducks are uniquely adapted for life in the forest, with strong claws on their webbed toes that allow them to perch on tree branches. Scaring up a pair of wood ducks together is common, because these ducks find a mate on their wintering grounds and arrive home together.

367 – Icy Wonders of Chequamegon Bay

The first ice cave was a wonder to behold. Crouching low, we shuffled into the crack that was the cave entrance. The light from our headlamps danced across the cave walls and highlighted the mass of clear ice that extended from the ceiling to the surface of the lake. As other tour guests took pictures with the glowing ice, I was marveling at the cave formation. Sitting under a low-hanging section of the cave, I began to think about how these caves along Chequamegon Bay are formed.

366 – Loon Behavior on Lake Jocassee

For recording time-activity-budgets for loons, Jay has an app on his phone that is set to beep at 2-minute intervals for an hour. At every beep, the binocular-wielding observers help the recorder mark down the behavior. Was the loon resting, locomoting, preening, foraging, or being aggressive? And was the loon within 25 body lengths of another loon? How many loons? One of the main goals of this research is to compare how loons on the salt-free waters of Lake Jocassee spend their time, versus loons who spend their winter on the ocean.

365 – The Loons of Lake Jocassee

The first day of Loon Camp begins with a count of all the loons on Lake Jocassee, which is why I was now puttering through the upper lake on a pontoon boat with Jay, Brooks, and seven other “loonatics.” With eyes scanning and binoculars at the ready, we spotted solo loons fishing in the deep water, rafts of loons preening near shore, and gaggles of smaller waterfowl like horned grebes, too. Jay kept the tally on his data sheet, and we were free to be amazed by the loons. 

364 – Winter Wind and Wildflowers with Lois Nestel

As the snow melts and I enter the melancholy often brought on by mud season, I find myself seeking comfort in the words of Lois Nestel, the founding naturalist, director, and curator of the Cable Natural History Museum. She wrote:

“Now there seems a desolation and bitterness in the wind as though it mourns the sadness and injustice in the world. But the wind is not governed by political upheavals, poverty or crime. It is as it has always been. Only the listener, the endurer, has changed.”

363 – Heaven in the Northwoods

This week Heaven Walker starts to explore the Northwoods.

362 – Black-backed Woodpecker in the Bog

I hardly needed to zoom in to see the bird’s black head, white face with black stripe, black-and-white barring on their flanks, and solid black back. Five years ago I’d seen an almost identical woodpecker in this same bog, but that one had a stripe of white down the middle of their back identifying them as a three-toed woodpecker. This was their cousin, a black-backed woodpecker.

361 – The Breeze of Balance

The wind can be a symbol of unity, freedom, eternity and balance. It is as true ecologically as it is metaphorically. As the winter winds swirl around you, take moment to appreciate the wind’s role in encouraging balance and unity in our sometimes stormy world.

360 – Frost Cracks

It wasn’t long before someone keyed in on an adorably squiqqly line snaking up the length of a tree. A frost crack! Long ago I learned that these cracks burst open with a noise like a rifle shot as a sunny day plunges into a frigid night. I couldn’t remember, though: was it the contraction of cooling wood, or the expansion of ice that caused the trunk to split? Both make sense. I pondered this as we hiked along, and also tried to spot more cracks throughout the forest.

359 – The Sweetness of Bitter Cold

You know it’s chilly when even Lake Superior can see their own breath. During a recent period of bitter cold, there was sea smoke drifting across the shining gray wavelets near Grand Marais, MN. Lake water had also formed ice on the rocks near shore, and we circumnavigated Artist’s Point to admire Nature’s sculptures. All the while, a small flock of mallard ducks bobbed on the waves in East Bay, behind the protective curve of Artist’s Point in Lake Superior. Then, driving home, something large swooped across the highway in front of us and several feet above the car. The blunt face and tapered silhouette were unmistakable characteristics of a Great Gray Owl—my first one in the wild! This day may have been bitter cold, but that made the beauty in it all the more sweet.

358 – Second Grade Tracking Stories

Murmurs of interest rippled through the classroom as I spread a rectangle of green felt on the floor at the front of the room. The murmurs became questions as I placed two lines of life-sized animal tracks, printed and cut out of white paper, onto the felt. When I finally invited the second graders to come up and gather around the felt, I was amazed by the almost instantaneous formation of a perimeter of kneeling children, totally focused on the scene.

357 – Operation Owl Rescue

On Christmas Day, I found myself driving from Lutsen, Minn., to Duluth with a very unusual package next to my skis and duffle bag.
To reassure ourselves that the owl was still alive, Christine opened one of the flaps on the box. Staring up at us were two giant yellow eyes nestled into satellite dishes of gray-patterned feathers that funnel sound into the owl’s hidden ears. 

356 – Wilson’s Warbler WOW

Gathered around a bonfire on the Winter Solstice, the hostess asked us each to share one moment from the past year that made us go, “Wow!” Despite the fact that my year had included rafting the Colorado River through the Grand Canyon, my favorite “wow” moment happened on a river much closer to home. One lovely afternoon last May, I set out with a friend to paddle an upper section of the Namekagon River. Approaching a bridge, a burst of twittering, movement, and flashes of yellow in the alder shrubs drew my attention. Squinting, I thought I spotted a black cap on one of the tiny heads, and quickly pulled into an eddy.

Sure enough, our binoculars revealed a flock of half-a-dozen or more little birds, “yellow as a lemon, with a smooth, black cap…” as Mary Oliver described them. Laughing in delight, we felt like we’d just conjured these Wilson’s Warblers with her poem.

355 – A Black-capped Brain

Chickadees cache as many as one hundred thousand food items per year. Not only do chickadees remember their seed cache sites, but they also remember details like which food items were the most favored and which seeds have already been eaten by them or by a thief. To support such an incredible memory, chickadees grow 30 percent more neurons in the fall when caching behavior peaks. Last April, researchers at Columbia University added to our understanding of chickadee memory. They discovered that chickadees create “neural barcodes” and essentially create their own system for inventory and checkout—just like at a grocery store!

354 – A Stomach for the Holidays

While digesting one of the many rounds of holiday feasts and leftovers, with plates of cookies in between, a headline caught my eye: “Big brains or big guts: Choose one.” As much as the post-holiday-dinner-brain-fog is real, I don’t love the implications of those options. Luckily, the article wasn’t about humans. It was examining birds in cold, highly variable habitats, and their struggle to survive. Essentially, birds have two options: spend energy maintaining a big brain that allows them to find high-quality food, or spend energy maintaining a large stomach that can make low-quality food sufficient in high quantities. According to the research, if you are a bird who needs to survive cold winters, you must choose one. There’s no middle ground.

353 – The Color Splash of Mountain-ash

In a landscape of winter white, bits of color really pop. Recently I was on the North Shore of Minnesota when they received several inches of fluffy, wonderful snow. The forest seemed decked out for Christmas with clusters of bright red mountain-ash berries adding color in the woods along the ski trails, around town, and on the rocky shore of Lake Superior. Ruffed grouse appreciate them even more, I’m sure, as they perch in the dark purple twigs and nibble both berries and buds. And now the trees have given me a bit of a mystery to nibble on too…

352 – Red-eyed Vireo Nests

The lack of leaves in this “see-through season” reveals aspects of the landscape otherwise obscured. For example, “Check out that nest!” I exclaimed to my friend, and we admired the small cup suspended between a Y in the sugar maple twigs. The placement of the nest, plus the few pale strips of paper from a bald-faced hornet nest woven among grass, bark, and pine needles, told me that it was likely built by a red-eyed vireo.

351 – Winter Songs of White-Throated Sparrows

On a recent hike in Virginia, a song burst out of a bush beside us. The white-throated sparrow riffed on their usual song, experimenting with a gravely “sweet can-a-NA-da can-a!” “Jazzy!” We laughed to each other. I don’t usually expect birds to sing in their winter habitat. Birds’ songs are typically used to attract mates and defend territories, and therefore are most useful in spring and summer. So, we figured we were hearing a young male practicing for the coming year. That would also explain why the amateur’s “sub-songs” were tending shorter and with more variations in rhythm and tone. As it turns out, that was only part of the story.

350 – A Dandelion Smile

Head down, I hurried toward the post office. Then, a spot of color made me stop and smile. A single yellow dandelion and its star of vibrant, toothy leaves nestled into the grass. I’ve always loved dandelions. And, the dandelion may be more useful than I ever imagined! The Kazakh dandelion, a relative of the one in your yard, is an excellent source of natural rubber.

349 – Adventures with Bagworm Moths

Bagworms are the larvae of tiny moths. When they hatch, their first act is to spin a silken sleeping bag and then decorate it with bits of their surroundings. Grass bagworms use little straws of dry grass, which also creates excellent camouflage. But why do I find these cases stuck to my windows and walls instead of on plants?

348 – Cyanobacteria Then and Now

Once upon a time, and by that, I mean 1.9 billion years ago, the atmosphere was filled with carbon dioxide and methane, and the first inklings of life had only just begun. Volcanic activity in the early oceans, and erosion off the few continents, enriched the water with iron and silica. Cyanobacteria bloomed in those mineral-rich seas, and they also produced at least one type of toxin: oxygen.

347 – In the Dark

Light from the dining hall at Upham Woods Outdoor Learning Center spilled out, down the hill, under the pines, and onto the bank of the Wisconsin River, where a handful of environmental educators were waiting for a night hike to begin.

I almost hadn’t joined the group. This was the final night of the Wisconsin Association of Environmental Education annual conference, and I had a long drive home the next day. Being sleepy for that wouldn’t be ideal. But it had been years since I’d been on a night hike, and I didn’t want to miss out.

346 – Ptarmigans on Top of the World

An odd series of hollow little clucks and rattles emanated from a patch of lichen-crusted rocks. Was there a friendly alien hiding nearby? Or maybe a Star Wars character that only Han Solo can understand? With short, jerking movements, the camouflaged chatterboxes revealed their identity: ptarmigans.

345 – A Beautiful Orange Day

The wool of my favorite old rusty orange sweater felt warm and scratchy as I stuffed it into my backpack next to a jacket and camera. The low gray clouds hung onto their rain, but wind gusts flung water drops off the trees as I walked to my car. As soon as I turned onto the gravel road, though, I knew I’d made the right decision. The much-needed rain had washed dust off the autumn leaves and saturated their colors. This was a perfect day for a scenic drive through a rainbow forest.

344 – Paddling Among Icebergs

Ever since I discovered how to read the glaciated landscape of Northern Minnesota and Wisconsin, I’ve been fascinated by these massive forces of nature. Admiring them from afar, seeing them up close, paddling among icebergs, touching their ice…glaciers are even more amazing than I’d expected. This week I’ve been busy leading field trips, but I’ve been dreaming of a time when I was a participant on two field trips that involved paddling near glaciers in Alaska.

343 – A Gift of Geology, Artesian Wells

A Gift of Geology: Artesian Wells By Elliot Witscher with Emily Stone
In the bright sunlight and heat of the afternoon, the cool, fresh, flowing water from a pipe in Prentice Park in Ashland, WI, was a welcome treat. I wasn’t expecting to find a unique geological feature in an unassuming city park. But walking down the hill from the parking lot, we found a plain metal pipe, surrounded by gravel, with water gushing from it. Standing in a circle with the 20 other people also taking the Wisconsin Master Naturalist Volunteer Training, I learned from Professor Tom Fitz that this was a flowing artesian well.

342 – Four Out of Five Loons Agree

As our water taxi motored into the harbor, a gray-headed water bird floated around the corner of a barnacle-crusted rock. A Pacific Loon!
Having spotted one new species of loon, my interest in seeing the others grew. The afternoon that I arrived at the Toolik Field Station to prepare for doing caribou research, I took a short walk around the base to get a feel for the area. The tremolo of a loon flying overhead sent a thrill down my spine, and I watched the large bird land on the far side of Toolik Lake. Were they a Common Loon? They sounded similar. But the logo for Toolik features a Yellow-billed Loon, and I was sure the scientists would have chosen them deliberately. Now that I’d seen the most similar loon to the ones I’d left back home, my last goal was to see the most different loon.

341 – First Grade Spiders

A small group of first graders nearly vibrated with excitement as they gathered in a circle on the carpet at the front of their room. They remembered me from last school year, when I’d brought tubs full of nature stuff to their kindergarten classroom. For those first Museum Mobile visits, we focused on exploring nature using our five senses. Now, as first graders, I explained, we get to practice those skills again…by using our eyes to make observations about spiders! I was heartened by the wave of enthusiasm – not fear – that rippled through the group.

340 – Grand Canyon Connections

Floating down the river, exploring the side canyons, relaxing around camp, I was always on the lookout for both the novel and the familiar. A giant insect I’d never seen before but knew immediately to be a Tarantula-hawk Wasp caught my attention just as easily as the glossy black feathers of a Common Raven. After a few days of pointing out something I’d noticed, or explaining the basics of a geological feature, I found more questions coming my way from the other participants. With each teachable moment, I felt more connected to both the canyon and my fellow rafters. I wasn’t surprised at the way this unfolded, and probably, neither are you.

339 – Listening in Elk Habitat

Due to a stuffy nose, I’m not recording a new episode for you this week. I did pull forward this episode from 2023 about the elk herd near Clam Lake. 

Morning mist hung low in the sky as a dozen elk ran across a clearing. A similarly sized herd of Museum members held our breath and grinned at our good luck. It was luck 3 billion years in the making.

338 – On Top of the World

Curtains of vibrant lights were moving just above the horizon. The aurora! My jaw must have dropped as I stumbled backward to lean against the car, and tears welled up as I tilted my head back for a better view. The moon hung full and bright on my east. To my west, spruce trees were silhouetted against the faint, rosy afterglow of the setting sun. And all across my southern sky, northern lights danced in curtains of green and white and pink. The curtains were woven of many wispy streaks, as if I was seeing the individual particles of solar wind blazing through our atmosphere. Northern lights are not just an awesome benefit to living on Earth; they are an absolute necessity to our survival. Our Earth defends us. And the result is unspeakable beauty.

337 – Isle Royale How Did You Get Here

With the rough, rolling, cold, wet ferry ride behind us, we disembarked gratefully at the Windigo dock on the southwest corner of Isle Royale National Park. Isle Royale, a 45 mile long and 9 mile wide bedrock island, is teeming with life that somehow made the treacherous journey. We hoisted our packs and started off down the trail. Before long, we met several pairs of hikers just ending their trips. We asked about their route on the island, their hometown, and which ferry they took. In essence, we asked “How did you get here?” Mostly they used the water route, but one couple arrived by air in a float plane. Historically, making winter crossings by dogsled was also common. Isle Royale is not an easy place to get to, or to get around, and yet life surrounded us on all sides. Soon I started asking “How did you get here?” to everything we saw.

336 – Wonderful Waves

Cliffs rose out of the lake ahead of us and soon towered a few dozen feet above our heads. Millenia of waves had worked their way into weaker layers of rock and then continued to enlarge them grain by grain. Some hollows were still tiny, but others formed deep alcoves. They spoke of the power of persistence. As we rounded one corner, a sea arch with one leg out in the lake framed our view. In another spot, multiple caves had coalesced into a maze we could paddle through.

After hours on the water, we returned to dry land to find food and shade. Taking our dessert to-go, we sat at a picnic table with a view of the lake and remarked about just how restful and healing the day had been. The combination of soaking in sunshine; gazing at and jumping in clean water; feeling awe at the ancient rocks; and admiring the beauty of life, had worked a special kind of magic on our moods.

335 – Sarah Talks about Lampreys

Sarah Montzka is about to start their senior year as a wildlife education major at UW Stevens Point. This summer, as a Summer Naturalist Intern at the Museum, they taught our Junior Naturalist programs, assisted with live animal care, and showed a real talent for finding and appreciating the oddest parts of nature. 

This week Sarah will tell you all about lampreys!
From drab lichen mimics to shimmering green wings; micromoths smaller than a grain of rice to underwing moths the size of my palm; we were captivated by the multitudes of mysterious moths.

334 – Mysterious Moths

The main event of the moth workshop came after dark. Kyle hung a white sheet with a mercury vapor lamp across an old driveway. Then he painted fermented banana goo onto the trunks of trees along the drive. Until almost midnight, our little group walked from tree to tree to the sheet and back, with stops at patches of blooming milkweed in between.

From drab lichen mimics to shimmering green wings; micromoths smaller than a grain of rice to underwing moths the size of my palm; we were captivated by the multitudes of mysterious moths.
