Natural Connections

As I climbed back into my car with a camera full of more lovely wildflower photos, I smiled at my good luck. Here in Wisconsin and Minnesota, we have quite a variety of habitats and soil types in a relatively small area. I can explore rich soils and maple forests filled with trilliums, wild oats, and large-flowered bellwort one day, then delight in the bedrock home of bird's eye primrose (and a not-yet-booming mystery plant) the next. And now here I was enjoying prairie flowers in a barrens!  What do we have to thank for these riches? Why the glaciers, of course!

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. 

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! 

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. 

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.

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.

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. How can you help? If you see grosbeaks, post your photos to iNaturalist or eBird where scientists can use them as data to determine where the birds are and what they are eating. Or if you're lucky enough to see one with a colored band, report it to the USGS Bird Banding Laboratory. Learn about ways to prevent birds from colliding with your windows from the American Bird Conservancy. Keep cats inside. Keep your bird feeders clean and take them down if you notice sick birds. Support the Finch Research Network and other conservation organizations with your donations. Scientists have come together in an Evening Grosbeak Working Group to fill the knowledge gaps across priority areas like diet, causes of death, migratory and population dynamics, habitat, and climate change. Among other things, scientists are outfitting grosbeaks with satellite and radio transmitters and colored leg bands to help track their movements. 

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?

"'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.    Here's a few fun links to info about the Moon:    https://www.amazon.com/I-Know-Moon-Stephen-Anderson/dp/039923425X https://radiolab.org/podcast/the-moon-itself/transcript https://cablemuseumnaturalconnections.blogspot.com/2021/06/whip-poor-will.html https://cablemuseumnaturalconnections.blogspot.com/2018/09/stranger-than-we-can-imagine.html https://www.sciencealert.com/our-moon-is-curiously-lopsided-and-a-massive-impact-could-be-to-blame https://www.amnh.org/exhibitions/permanent/meteorites/meteorite-impacts/on-the-moon https://science.nasa.gov/moon/tidal-locking/ https://science.nasa.gov/moon/weather-on-the-moon/ https://science.nasa.gov/moon/formation/ https://science.nasa.gov/moon/composition/ https://www.universetoday.com/articles/moons-insides-still-hot-hot-hot-after-billions-of-years-of-formation-study

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.

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.

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.

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

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.

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.

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. 

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. 

"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. 

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. 

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.
