Field Notes

Sunday 12:55 PM, Tuesdays and Fridays at 4:54 PM

For keen observers, a walk to the grocery store or a hike up a mountain can inspire questions. Where do magpies nest?  Why doesn’t a spider stick to its own web? How do water striders keep from sinking?  Every week since 1992, Field Notes has inquired about Montana's  natural history. Produced by the Montana Natural History Center, Field Notes are written by naturalists, students and listeners about the puzzle-tree bark, eagle talons, woolly aphids and giant puffballs of western, central and southwestern Montana.

'Field Notes:' Reflections On Knowing A Wild Place

Jun 17, 2016
Allison de Jong

Montana has so much to offer for those who love wild places, and I’ve spent much of my time here exploring all the new spots I can in our lovely state. Yet there are a few places that I find myself returning to again and again. My favorite may be Glen Lakes in the Bitterroots.

Extremophiles: The Berkeley Pit's Silver Lining?

This story almost begins on a dark and stormy night in November of 1995, when 342 snow geese landed on Berkeley Pit Lake. Unfortunately, this was no ordinary lake and the story did not end well for these birds.

At the end of last summer, as I sat in an eddy on the Clark Fork River, something furry and black caught my eye, moving as smoothly as the water itself. I was looking at a North American river otter. Remembering studying sea otters in elementary school, I wondered if I had just seen something rare for this region, and decided to do a little research.

'Field Notes': All About The Western Meadowlark

If you have been in open country anywhere in Montana, you have heard, and probably seen, thunderchunks. These birds are everywhere, proclaiming territories and singing from fence posts, sage brush, and telephone poles.

I first visited Glacier National Park in June. Though winter had only recently loosened its grip on the Crown of the Continent, there were blue skies and sunshine as I hiked up a high-elevation glacial basin. The temperature was a balmy 60 degrees.

'Field Notes': Calliope Hummingbirds

It is mid-May, and I am living in a wall tent on a farm in the Mission Valley. The tent is white canvas, and sits next to the largest apple tree I have ever seen. The largest limb hangs high and wide and reaches over the top of the tent. This time of year, springtime, bees and flies and other pollinators dart between blossoms on that high limb. And inside the tent, all lit up with sunshine, it feels like the canvas house is humming and buzzing. This spring, I feel like I’m living in a cloud of wing beats.

Cottonwoods: Where Wildlife Take Refuge In Winter

Thinking about plants in winter recently, I remembered a particular good-sized cottonwood I saw while walking along a riverbank. What was its story?

From James Halfpenny’s fascinating book “Winter:  An Ecological Handbook,” I learned that cottonwoods, like many northern trees, have very special adaptations to survive the long, cold winters. They begin their “hardening” process in the fall, as temperatures begin to drop and the amount of daylight decreases.  Leaves typically fall during this stage of hardening, but the process continues as winter settles in. 

'Field Notes': Bird Watching At The Polson Dump

Bird watching at the Polson dump is not for the faint of heart. The task requires an unnatural tolerance of gigantic machinery operated by large men wearing overalls and permanent looks of disapproval. But if you're serious about observing gulls, you need to go to where trucks discard trash at the edge of town. Evidently it's much easier for gulls to pick through our leftovers than to catch freshwater shrimp and fish.

Burnt snags in western Montana

One of my favorite places to look in the forest is up. I love the way trees frame patches of sky, and how rays of sun slide over the branches and slant into pockets of darkness. On a recent stroll through the woods near Echo lake, I found myself, as usual, looking up. I saw mostly fir and birch trees, and I took their narrow trunks and modest heights as signs of a young forest. But it was a much older tree that caught my eye.

Are You Mis-Using These Common Tree Terms?

Apr 4, 2016
Some write of “conifers and deciduous trees” as if they are somehow different. But, of course, when describing trees the words coniferous and deciduous may be distinctions without a difference.

As I split and stacked my winter firewood this fall in preparation for the long nights to come, trees in the surrounding forest were also preparing for winter. While I watched their leaves turning yellow along the flank of the Bitterroot Mountains, I found myself considering the confusing terms people use to describe those trees. In particular, folks tend to mix up perfectly good words in ways that leave me more befuddled than enlightened.
