Hello Readers!

Students often ask me where I get my ideas for books, and the answer surprises them: in my “backyard” in Maine! I have hunted for invisible “zombie bears” in the woods (they’re real), gotten soaked while helping spotted salamanders cross the road to their vernal pools on rainy spring nights, and slogged through stinky marsh mud to spy on shorebirds. Not to mention getting bitten by zillions of mosquitoes. It’s all part of research.

And you thought writers just sat at their desks all day. Well, I do plenty of that, too. Once I get an idea, I spend months reading, interviewing scientists, taking notes, and organizing the information I have gathered. Finally, I start writing—and rewriting many, many times. Eighteen months laterTa Da! A book!

I hope reading my books inspires you to explore your backyard, local parks, and wild places. I’d love to hear about the cool things you see and learn about—you can write to me at

Slime Power!

Velvet worms shoot nets of “super slime” to snare their prey. The more a spider or cricket struggles, the more the slime net hardens. There’s no escape. Scientists recently discovered the amazing properties of velvet worm slime, which solidifies into strong threads when exposed to force. More remarkable, these threads can be dissolved in water […]

World’s Coolest Reptile?

Three rows of teeth. A third eye. A “chill” nocturnal lifestyle. The tuatara is unlike any other reptile in the world. Easy to mistake for a lizard or an iguana, the tuatara is neither. This Extreme Survivor is the last living Sphenodon, a diverse and ancient order of reptiles that slithered around with the dinosaurs […]

A Swell Shell

Ancestors of the nautilus were “the great white sharks” of the prehistoric seas. They evolved an edge that made them efficient hunters: a shell that allowed them to float—and stalk other ancient creatures still stuck crawling around on the ocean floor. Today’s nautiluses are smaller and more mild mannered than their ancestors from 500 million […]

Aliens of the Sea?

Wading in the icy waters of Maine’s Penobscot Bay one summer day, I spotted transparent creatures near the surface rippling with rainbow bands of light. I thought I was seeing things until a scientist friend told me that these thumb-long, otherworldly critters are called comb jellies. He explained that their namesake “combs” — rows of […]

Maine’s Songbird Superhighway

The morning air smells of balsam and wet duff as Adrienne Leppold sets out on a narrow trail to check the mist nets she set up before dawn to capture birds in a patch of forest in Orono. A great-crested flycatcher cries “wheep, WHEEP,” one of a dozen or so species calling and singing in […]

While You Were In  

While you were in, a hermit thrush called. There’s no telling whether or when he’ll call again, fluting his song into the forest, where it will linger less than an instant. A doe stopped by while you were in, entertaining a parade of anxious thoughts. She decapitated your favorite phlox, the ones with the snowy […]

A Walk on the Wild Side

The moose peeks out between tall white pines, her dark brown hide blending with the bark. She swivels her ears and ambles toward us. My heart speeds up as she draws closer. She pokes her massive head through the door of the feeding station, where Steve Oliveri awaits with one of her favorite treats: sweet […]
