Break off a sprig of big sagebrush and inhale its aroma: the fragrance is clean, sharp and as cool as the smell of winter. Call it camphor blended with a touch of Christmas. Crush a few leaves between your fingertips and the scent is suddenly somewhat bitter and more pungent. Let the sprig dry for a few hours and you’ll find that the fragrance gradually loses its bite, softening to crisp evergreen with a hint of juicy berry.

Most people are familiar with the showy red or yellow flowers of the Indian paintbrushes. They can be found from the dry valley grasslands to lush alpine meadows. There are 21 species of the paintbrush just in Montana, including bristly paintbrush, the red-flowered species of dry slopes and scarlet paintbrush which is common in meadows and along streams.

Several decades back while working as a biologist in Oregon, I was picking rocks off the bottom of a rushing stream. While investigating the underlying aquatic insects, I encountered an odd animal. It was what appeared to be a tadpole stuck to the bottom of the rock! Assuming all frogs and tadpoles occur in swamps, not in high elevation rushing streams, I wondered what it was doing there.

Red-winged blackbirds are a common species in Montana and I’d seen plenty of them together, particularly near ponds and lakes. But in winter, they can flock in congregations of millions of birds that include other species of blackbirds and starlings.

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.
