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:' Great Horned Owls

I was admiring a blanket of stars spread above Lake Como in Montana’s Bitterroot valley, when out of the stillness of the chill winter night came floating a deep, dignified, hoo-h’HOO-hoo-hoo.

There are few things more evocative of wildness in the northern woods than the hooting of great horned owls.

Not long ago I was out hiking in the mountains during one glowing afternoon. I turned off the trail and headed into the woods in search of a comfortable place to nestle down and daydream. As I found a spot for myself a red squirrel came bounding toward me on a fallen log. It jumped onto the trunk of a ponderosa pine and gave me that bright-eyed stare accompanied by several swishes of its feathery tail. Then it headed up the tree and disappeared among the high branches. I'd been sitting in a peaceful reverie for only a minute when suddenly a pine cone came crashing to the ground just a couple of feet away. I looked up and saw two more falling. The squirrel was attacking me!

Field Notes: Winter Clouds

At no other time is the parting of clouds felt more powerfully than outdoors, at the height of winter.

On this particular day, the clouds break intermittently and when they do, motion ensues. The peeps and chatters of birds start, and you can see them dart and cling through a white and shifting world. The snow itself starts to awaken and come alive - melty, unstable layers slide down the steeples of trees.

Why No Two Snowflakes Look Alike

You know the old saying “no two snowflakes are alike”? Well, there may be more truth to that than you think. I am from Hillsboro, Oregon, where the snow falls in wet, indistinguishable clumps. When I moved to Montana, I immediately noticed a difference.

Singing In The Snow: Montana's Winter Bird Songs

If you go cross-country skiing in the North American woods, you’re likely to hear all manner of twittering and chattering as flocks of birds like chickadees, finches, and nuthatches bustle about finding food and warning each other about danger. Most birds will call like this at any time of year, but reserve singing for signaling a territory or attracting mates during the breeding season, typically in spring.
