Nature notes and inquiry from the Montana Natural History Center.
-
This Montana prairie holds a secret. This is coulee country, a landscape peppered with gullies waiting to be explored. -
A visitor to the Yellowstone National Park helped with a calf struggling to cross a river. After, the calf began approaching people and cars, hazardous for all concerned. -
Wind has a way of blowing in and cutting short an adventure. It can ruin a picnic. It can wreak havoc on the best-laid plans. At its worst, it can be dangerous and even deadly. But it also creates the breeze that shakes the leaves of quaking aspen. It carries the seeds of black cottonwood and the wings of Red-tailed Hawks to new destinations. -
Most plants conduct photosynthesis and make their own food from sunlight, carbon dioxide and water. Fungus flowers, however, cannot conduct photosynthesis, making them not only look bizarre but function in a bizarre manner. -
Tyrell’s tufted, along with most jumping spider species, is not aggressive. Jumping spiders actively hunt their food using their speed, the hunters of the arachnid world. -
We continue walking, giving the shoreline a wide berth to avoid scaring any loons that might be around. Now we're on the opposite side of the lake and—we see them. Two adult Common Loons. Oh, they're lovely: streamlined, low-slung bodies, perfect for diving. Sleek black heads, red eyes, and characteristic black-and-white coloration that makes it easy to identify them. -
It’s June and I’m in a dreamy meadow deep in the backcountry of Mount Rainier National Park, looking for toads. My mission: find the toads, count the toads, save the toads—in that order. -
Crawdads have specialized cells in their exoskeletons that allow them to change color to adapt to their surroundings. The cells, called chromatophores, work to either concentrate or disperse pigment. Similar cells in chameleons and octopuses allow for a quick color change. But, for crawdads, the process is slower. -
Northern Harriers are considered one of the most elusive raptors, and some of the most accomplished wildlife photographers admit how difficult they are to photograph. Male Harriers, with their white underside and opaque gray-back plumage, seem to be even more challenging to photograph than the brown and much larger females. For that reason, many birders and photographers call male Harriers “Gray Ghosts.”. One moment they’re in your viewfinder, the next, they’re gone. -
I was delighted to observe such an unusual visitor, but he had a bigger surprise for me. As I watched him forage through my yard he did something unique I had never seen, heard of, nor even imagined! -
Tufted evening primrose is one of the loveliest native plants found in dry climates across western and central North America. Its botanical name translates to “wine seeker, densely clumped,” which is apt for a low-growing, mounded plant with very fragrant, citrus-scented flowers. -
I could not articulate what pulled me off the trail, but I followed the urge all the way to the base of the towering tree, a western redcedar. I stood, neck bent back to take in its shading canopy of soft, scaly leaves. We greeted one another in an exchange that predates my ancestors taking human form: the mammalian exhale of carbon dioxide and inhale of oxygen from the trees.

As spring rains tame the dust of the Montana plains and rinse the grasses briefly to green, spadefoot toads (Spea bombifrons) will stir for the first time in a year and clamber from burrows beneath the soil’s frostline to the surface. There they will congregate in pools of snowmelt and rainwater, and they will sing. -
After several long moments the bird erupted out of the water, landing on its stone while droplets rolled off its tightly woven feathers, a look of nonchalance twinkling in its chocolate-brown eye. I blinked. A diving songbird? I thought I knew water birds: ducks, ospreys, bald eagles, kingfishers. But here was a robin-sized bird using river stones as diving boards, doing who knows what in currents too strong for me to cross. -
One warm, sunny day I saw a crow squatting low on a large ant hill, head high, wingtips outstretched and fluttering softly on the ground. I had never seen this behavior before and I wondered if she might be injured. I watched her with concern before she stood up, briefly picked at her feathers, and flew away. -
One afternoon while balcony-bird-watching, my attention was captured by a tiny black speck aggressively pursuing much larger birds, undeterred by the threat of sharp beaks and deadly talons. With equal measure, he intimidated crows, Osprey, eagles, vultures, and herons away from his territorial claim along the riverbank. With my binoculars and guidebook in hand, I identified him as a male Red-winged Blackbird after he flashed the telltale red and yellow striped epaulets on his shoulders, and loudly sang, “CONK-LA-REEEEE!” when he settled on a shoreline tree branch. -
Many little creatures are decomposers and their lives depend on the death of others; such is the cycle of life. Recycling in its truest form! -
Bird surveys in my backyard. I look forward to doing them every morning when I wake up. What species will I get today? -
Whenever you walk out your door into your yard, alley, or front stoop you will likely see them: little brown birds in raucous groups of up to 200 individuals. Many see them as pests and because they are small, brown, nondescript, and everywhere they are often overlooked. They are House Sparrows (Passer domesticus). -
The Lakota call it the tree of life, due to the star, and use its branches in their Sun Dance ceremony. Dakota Native Americans tell a story of a little star who wanted to hear the sounds and songs of humans and hid in the cottonwood so as not to disturb the people as they worked. -
A La Niña event typically lasts from 9 to 12 months, and occurs roughly once every three to five years, often following its counterpart, El Niño. Both events influence weather throughout North America and beyond, though these changes manifest in different ways throughout various regions. -
What began as a hike to enjoy an early autumn afternoon transformed into a mission to sow and grow a stand of Pinus ponderosa from seed. I had become enthralled by this possibility as I traversed miles of trails shaded by canopies of pine in Missoula’s Rattlesnake Valley.
