We call them shooting stars, and they never fail to make us catch our breath in surprise and wonder. But they’re not stars at all. Those bright, brief streaks across the night sky are…
The Outside Story
Zebra Mussels
Invasive species have earned their bad reputations. English sparrows compete with native birds from Newfoundland to South America. Australian brown tree snakes are well on their way to…
Black Swallowtails Have Many Disguises
It was the dotted, orangey-yellow and black stripes that stood out, drawing my son’s gaze to the edge of the sandbox. A small caterpillar clung to the goutweed, munching away on the…
See What’s in the Milkweed Patch
Eight or so years ago I collected milkweed seeds and painstakingly buried them one at a time under leaf debris at the back edge of my yard, hoping they would mature and attract more monarch…
No Easy Recovery for Bats
In 2006, I joined a team of biologists to trap bats in Vermont’s Chittenden County. We were searching for North America’s rarest bat, the Indiana bat, which had recently been…
A Thorny Problem: Multiflora Rose
Multiflora rose is not without charm; in fact, there was a time when people went out of their way to plant it. The pretty spring flowers have a sweet scent; birds nest in the sturdy branches…
Snakes and Toads Provide Garden Pest Control
Encountering a snake in the garden causes many people to shriek or even panic. Yet snakes and another often unloved creature, the American toad, are among the most effective forms of pest…
Cattails: Nature’s Supermarket
This past winter I spent three months exploring East Africa, traveling through ten different countries and covering over 8,077 miles. I was continuously impressed with how much local guides…
Bees Feel Flower Buzz
Imagine you had a power that allowed you to pick up nearby objects without actually touching them. Imagine this power could help you find and choose the best foods while shopping. Imagine you…
Bobcats
The distinctively feline tracks through the snow in our woods last winter intrigued me. They would follow the narrow ski trail a ways, then meander into the trees or, sometimes, seem to…
Keeping it Clean Downstream
In peaceful streams, aquatic macroinvertebrates such as crayfish, stoneflies, and caddisflies travel over and under submerged rocks, foraging for other invertebrates, leaves, and algae. When…
Spider Silk
There is an all-natural material, produced at room temperature, that can be used to build homes, to make protective coverings, to hunt and trap, and even to swing through the air. It’s…
Living on the Fledge
On a recent afternoon, I was driving on my road in Thetford when I saw a baby ruffed grouse about the size of a pin cushion scurry into the bushes. I had the same impulse I did as a…
Elms on the Rebound?
On a recent damp May morning I walked around Dartmouth College in Hanover, New Hampshire, with arborist Brian Beaty. While he is responsible for all of the trees in the center of the campus,…
Flat Stanley and the Centipede
Biologists sometimes field questions about a “huge scary bug” that appeared in someone’s home or worse yet on their person. Most turn out to be benign organisms that ended up…
The Tree Fox
When you think of foxes (if you ever do), you likely picture the ginger-coated red fox, like Mr. Tod from Beatrix Potter’s fantastical children’s tales, only without the dapper…
Maple’s Other Delicacy
Helicopters. Keys. Whirligigs. Samaras. Whatever you call the winged seeds released by maple trees, here’s one more word for them: delicious. Like many New Englanders, I have fond…
Bee Mimics: Their Buzz is Worse Than Their Sting
A while back I had a few hives of honey bees parked at a beef farm down the road, tucked up against a stone wall just outside a pasture. One day the owner called to say that my bees had…
Sea Lamprey: Scary Looking, but Good for the River
Most people do not like sea lampreys even though they have never even seen one. The fish have a bad reputation as an invasive species in Lake Champlain. Their appearance is also alarming.…
Fawns Hide In Plain Sight
Last May, while out hiking, I came across a young fawn curled up in the ferns only three feet from the Appalachian Trail. My husband and our dog had already walked right by without noticing…
