The Outside Story

The Trees of Christmas Past and Future

You picked it out, maybe cut it down, brought it home, watered it, and decorated it. But do you know what species of tree that is surrounded by presents in your living room? If you purchased…

Carpenter Ants

Mention carpenter ants, and Declan McCabe, chair of the biology department at St. Michael’s College in Colchester, Vermont, thinks about the time he got a lungful of formic acid. He had…

Glacier-Carved Rocks: Evidence of our Ice Age Past

When I’m hiking, I like to watch for rock basins, sometimes as small as cupped hands, that appear along summits and ridgelines. These are “thin places.” When filled with…

House Sparrows in Winter

House sparrows – those little brown and gray birds that flash mob the bird feeder – are common and easy to see. They’re quarrelsome, noisy, and when they’re on the…

The Color of Cranberries

As a kid fidgeting at my grandmother’s Thanksgiving table, I often wondered, what’s the point of cranberries? She had a live-in Irish cook who insisted on serving whole cranberries…

Water Scorpions: Underwater Assassins

Recently, my daughter participated in Odyssey of the Mind, a creative problem solving competition devoted to ingenuity and team work. As an entomologist, I was thrilled to learn that the…

Tamarack

Tamarack is a tree with a number of aliases – hackmatack, eastern larch, or if you’re from northern Maine and feeling contrary, juniper. Whatever you call it, this scraggly tree,…

It’s a Shell Game for Turtles

Years ago, I stopped when I saw a turtle attempting to cross a high-traffic road. When I picked it up, I noticed its intricately sculpted shell. The top, or carapace, was covered with layers…

Canada Geese – Migrant or Resident?

A large V of Canada geese flying noisily over my head – and traveling north, rather than south – got me wondering about the ins and outs of fall migration. Shouldn’t these…

Heirloom Apples

As Eve so famously discovered, apples are alluring. These brightly colored orbs tempt us with crisp flesh and juicy sweetness. It’s no wonder that apples have spread throughout the…

Raccoons Prepare for Winter

Almost every time I checked the game camera last summer – whether it was stationed near the compost, pointed into the field, or hidden at the edge of the woods – I found photos of…

How Do Birds Know When To Migrate?

On the north end of my home is a nest site favored by eastern phoebes. Every year a pair shows up, sets up house, and raises a family. They arrive early in the spring, and I spend the long…

Dry Run

Scenes from the West’s five-year drought are striking – the cracked mud at the bottom of a dry reservoir, forests in flames. Wonder what a drought would look like in Vermont and…

Fall Peepers

We like to think that everything in nature has its own particular time and place. But nature is fond of throwing us curves. As a naturalist, a common question I’m asked during foliage…

An Abundance of Caution: Wild Food and Risk

“I’ve got a botanical question for you,” my friend said as he came into my classroom the other day. “Is black nightshade edible?” He’d found some growing…

Tobacco Hornworms: Big, Green, and in the Garden

The big, meaty green caterpillars that many of us have been fighting to eradicate from our gardens this summer make plenty of people squirm. In part it’s because they are among the…

Cloudy with a Chance of Flies: Non-Biting Midges

Clouds of tiny insects, rising and falling hypnotically along lake shores, contribute to the ambiance of warm summer evenings. My recent bike ride was interrupted by a lungful of this…

The Dirt on Roots

You can pretty much count on a tree to stay in one place, at least in the real world. Not so in fiction. Remember the walking, talking Ents in the Lord of the Rings movies? Or Groot, the…

Singing a Different Tune

Birdsong has always fascinated humans. Besides waking some of us up a wee bit too early in the morning, it has inspired musical compositions and immortal poetry. It has produced lush…

Squirrel is My Co-Pilot

The first red squirrel appeared at about 50 mph. It climbed up over my headrest and landed in my lap. I don’t recall the next few seconds very clearly, but according to my 5-year-old…
