Not With A Howl But A Whimper: Wolf Calls

"Take a dozen railroad whistles, braid them together, and then let one strand after another drop off, the last peal so frightfully piercing as to go through your heart and soul." According to biologist Stanley P. Young, that's a stockmen's take on the sound of a howling wolf pack. But it'll come as no surprise to any dog owner that while howling is the most recognizable of four different wolf vocalizations, under various circumstances, wolves also growl, whimper, and bark.

Natural History Under A Microscope

"Not long ago, I grabbed my boots, a small cooler, and a turkey baster from our kitchen. In just a few minutes, I had broken through the ice on the shore of the Bitterroot River, sucked up some water from under rocks, and squirted it into the cooler. I moved on a bit and watched two muskrats, while I listened to chickadees singing with the sounds of the river behind. This was natural history at its best, almost. It was about to get better. I returned home where my microscope was waiting to show me what minute life forms I had captured.

American Dippers: Singing From Montana's Icy Streams

"Skiing next to a creek north of Missoula on a morning so cold that ice crystals dance in the air, the world seems silent, asleep. Then a brilliant melody pours forth like a breath of spring. The sound seems to come from the water itself. I ski closer to the ice-lined creek and a splash in the shallows reveals a stub-tailed, plump little bird whose dark coloring blends perfectly with the drab gray rocks. This is a dipper, or water ouzel, a year-round native of Montana's rushing, forested streams.

The Trouble With Trumpeters

"By the 1930s, conservation groups across North America teamed up to help save the trumpeter, of which only 69 were known to exist. Various projects restored and increased breeding, wintering and wetland habitat, including the new Red Rock Lakes National Wildlife Refuge in southwest Montana. Trumpeter populations rebounded and reached almost 35,000 swans by 2005.

The Hornaday Bison: Killing Buffalo In Order To Save Them

"By the 1880s, bison numbers had dropped from millions to scant hundreds. Few people in the densely populated East viewed the coming extinction of the bison as an ecological and cultural loss. Naturalist William Temple Horaday was one of the first people to call for the conservation of bison, along with his friend, Theodore Roosevelt. Hornaday, chief taxidermist at the Smithsonian Institute, was outraged that the slaughter of bison was allowed to occur.

Ruffed Grouse: Strolling On And Exploding From The Snow

Their cryptic brown and white coloration makes ruffed grouse hard to see - often, the first sign you'll have of one is the deep sound of wings flapping, followed by an eruption of feathers nearby. A classic sound of spring in areas where ruffed grouse live is the booming sound of the male grouse, drumming atop a rock or log or mound, simultaneously announcing and defending its 6-10 acre territory. The sound has been described as "an engine trying to start."

Fungus Feeders Flying Around The Philodendron

"It was fall, and my favorite heirloom house plant had outgrown its container, so I replanted it in a larger pot. To do this, I used some potting soil that had been sitting in sacks in the backyard. Soon after, the house was teeming with little flies. I knew they came from the potted plant, but I had no idea what they were. It turns out they were dark-winged fungus gnats, which feed off fungus in potting soil. These persistent little insects have followed me from one rental house to another over the past two years.

"In the late Cretaceous period, from 90 to 65 million years ago, Montana had a lusher climate than today. The Rocky Mountains formed one edge of a vast inland sea - Fort Peck was beachfront property on the edge of that sea. There are three distinct sedimentary rock formations from that era running through the area. The T. rex, "Peck's Rex," was found in the Hell Creek formation in 1997, just inland from the ancient coast. The sparsely-fossilized Fox Hill sandstone is a remnant of the beach itself.
