As we hunker down for the winter weather, we’re frequently too preoccupied with what is in our front yards that we tend not to notice what isn’t there. The snow and ice have muscled out the grass, and the chilly sounds of the north wind have blown away the dawn chorus that woke us this summer. And short of finding a postcard in your mailbox from a warm exotic location, signed by your friendly neighborhood phoebe , you probably haven’t thought much about the birds that flitted through your yard just months ago.

Here at Something Wild, we’ve been thinking a lot about winter and the different strategies animals use to get through these cold, harsh months. There are quite a few techniques to survive winter if you don’t live in a toasty house with central heating or a roaring wood stove. The top 5 are: Don’t live here: Lots of animals live in the Northeast but many more stay away because of the harsh climate. Die in autumn: Some animals' life cycles are tied to the seasons and for those creatures not...

We’ve been hearing a lot about porcupines this year. They seem to be everywhere! It’s positively a plague of porcupines! So why are there so many? Biologists don’t have an official answer, but Dave Anderson has a hypothesis involving coyotes and fisher cats. The porcupine’s only real predator is the fisher. It takes a tough critter to eat a porcupine. Anecdotally, trackers and hunters are reporting that fisher numbers appear to be down this year, so it makes sense that porcupine numbers are...

Picture yourself in the grocery store. You’ve got an organized list in your hand and you’re looking for the things on that list. And as you go down the aisles you’re whizzing by dozens, maybe hundreds, of things on the shelves until your eye picks out that one jar of peanut butter that you have on your list. It’s an efficiency technique that helps you find what you’re looking for.

A common theme on Something Wild is breeding. (Which is why we always sip our tea with our pinkies extended.) Seriously, though, we talk about the how, when, where because there are a lot of different reproductive strategies that have evolved in nature. Today we take a closer look at two such strategies: semelparity and iteroparity.

As fall comes to a close, winter imminent, there is a quiet that sweeps across New Hampshire. We celebrate the changing of the leaves but once they’ve fallen from the trees there’s really not much to look at before snowfall, right? Of course not! There’s always something waiting to be discovered in your back yard and this time of year is no exception. Head outside and into the woods. The bare trees leave exposed that which was obscured earlier in the year. From stone walls to flora that may...

Black bears are as much a part of New Hampshire as fall foliage and stone walls, nevertheless they are a misunderstood species. To better understand the species, we wanted to talk to a bear, the closest thing we could get was Ben Kilham. And that’s pretty close, which is evident when you meet him. He’s over six-feet tall and moves with a slow ambling gait. His ursine tendencies aren’t surprising when you consider Kilham’s been studying and living with black bears for nearly 25 years.

Bats in New Hampshire have been struggling with White Nose Syndrome for the past few years. So we sat down with Wildlife Biologist Emily Preston from NH Fish and Game and Endangered Species Biologist Susi von Oettingen from U.S. Fish and Wildlife Service to find out how they’ve been faring recently. Obviously, bats are really important in our eco-system because they are the greatest predator of nighttime insects. As von Oettingen explained, NH hosts eight species of bats (among them: Little...

There’s been a lot of talk about Gypsy moths this year, especially in southern New England, where trees in some areas have been hit pretty hard by this voracious caterpillar. And it has sparked a lot of discussion about how people might help reduce the damage, but it’s worth remembering that the trees these caterpillars feed on are not entirely helpless.

November is a great time to spot golden eagles. They are a rare sight in New Hampshire, but they do pass through the state on their annual migration. Right now they’re on their way south to winter in the central Appalachians. They’ll pass back through the state in March on their way to Labrador and northern Quebec to nest. Golden eagles are sometimes confused with young bald eagles, but there are differences. When bald eagles are in flight, they hold their wings flat like a plank, but golden...

You may be familiar with hoarders (not the TV show, but same idea). In nature, a hoarder will hide food in one place. Everything it gathers will be stored in a single tree or den. But for some animals one food cache isn't enough. We call them scatter hoarders. A "scatter hoarder" hides food in a bunch of different places within its territory. The gray squirrel is a classic example, gathering acorns and burying them in trees or in the ground. Not all squirrels are hoarders. Red squirrels are ...

We don't often think of trees when we speak of "harvest." Corn is harvested; apples, tomatoes, squash are the fruits of the annual autumnal rite which is the province of our farmers. Maybe it's because those plants are harvested at the end of their lifespan that we don't lament the moment they are cut down. We're much more precious with our trees. Maybe because we associate de-forestation with developments of housing sub-divisions, or banal strip malls with all the character and scenic beauty...

Something Wild fan, Michael Carrier, wrote in recently, he said “If possible could you do a program about identifying some of the more common sounds you hear at dusk or night in New Hampshire.” Yeah, we can do that. So a typical evening scene in Anytown, New Hampshire is a symphony of sound. A screen door slams in the distance…a jake brake startles the neighbor’s dog…the weekend warrior fires up her motorcycle… But as the evening settles in and human sounds fade away we can better hear the...

How do you determine the age of a tree? Just count the rings, of course! One ring equals one year of growth. If you’ve ever stumbled upon a tree stump you may have even done it yourself. But if you’re counting rings on a stump, the life of that tree is over. So how do you count those rings while the tree is alive? Experts use a special tool called an “increment borer”. An increment borer is a tool used to extract a small core from a tree, allowing a dendrochronologist to count its rings...

In this part of the country the Corvid family includes blue jays, gray jays, crows, and ravens. And ravens – Corvus corax – are the smartest of this intelligent family, actually their brain to body ratio is on par with whales and the great apes. Ravens are pretty common in New Hampshire, probably more common than you think since at first glance they look a lot like crows. But there are some key differences between these two big black birds. First, ravens are bigger, their wingspan is almost...

It all started with a black squirrel. These rare creatures aren't a separate species - they're your garden variety gray squirrel, but a genetic mutation has given them a black fur coat. That got Dave wondering if a black squirrel has any advantages its fairer forebears don't (other than being incredibly popular among nature photographers). Wondering turned to arguing.

To everything there is a season and this is the season when we go swimming and we spend a lot of time talking about Cyanobacteria. So what is it, exactly? Sonya Carlson is head of the Beach Inspection Program with the state Department of Environmental Services and gave us a primer on the micro-organism. Cyanobacteria has been on earth for a long time, to the tune of 3.5 billion years! “In fact, we scientists think it's what created oxygen in our atmosphere, so it's a very important part of...

Today’s topic is thunderstorms. Summer in NH brings those triple H days – hazy, hot, and humid! On days like those there’s nothing more welcome than the arrival of a late-afternoon thunderstorm, leaving in its wake cool, refreshing air, scrubbed clean of haze and pollution.

At Something Wild we like to talk about some of the interesting wildlife or natural occurrences you can find in New Hampshire. We hope you learn a little something wild along the way; sometimes that’s birds and bees, sometimes that’s flowers and trees, but today we want to talk about that thing called love. Biophilia is an idea popularized by American ecologist and philosopher E.O. Wilson. He suggested that humans have an instinctive bond to other living creatures – that we’re innately...

Chris Shadler

Chris Schadler is a wild canid biologist, and for about 25 years, her specialty has been the coyote. The first confirmed case of coyotes in New Hampshire was an individual found in a trap in Holderness in the mid 1940s. But they have likely been here longer, because as Schadler points out, they didn’t parachute into Holderness, they will have migrated south from Canada.

Wild Turkey

There is a common misconception that wild turkeys were once extinct in New Hampshire but have since returned. Extinction is often confused with extirpation but they are actually two different concepts. Extinct refers to species no longer in existence, having no living representatives – gone everywhere. Things like the brontosaurus, which no longer occurred as of 10's of millions years ago, the wooly mammoth 10-thousand years ago, or the passenger pigeon only 10 decades ago. Extant describes...

Talk of turkey is usually relegated to the month of November as we stuff ourselves with eating yams and cranberry jelly, and watch college football. And the misperception about Ben Franklin proposing the wild turkey as our national bird, is usually not far behind.

Every week here at Something Wild we encourage you to go outside. It's easy to find the wild in New Hampshire, be it a walk on the beach, a hike in the woods or a quiet crepuscular kayak ride. However there are things you need to be mindful of when you're out. We've heard a lot about ticks but not so much about poison ivy. You've probably seen or come into contact with poison ivy at some point; the three waxy leaves with serrated edges. You probably also know you should avoid it. Don't touch touch the vine, don't touch the root. You can get a rash from any part of the plant.

There are few sounds in nature that command your attention as effectively as the rattle of a rattlesnake. And though these snakes are not aggressive, that sound does elicit a hard-wired, innate fear response. Roughly translating to “Watch Your Step, Mister!” the rattle is an alarm designed to stop trouble before it starts.

Biologists like to talk about crocodiles, cassowaries, even chickens as being descendants of the dinosaurs. But in your back yard is likely something that can trace its ancestry to before the dinosaurs, some 360 million years ago. We’re talking about Ferns!

A Something Wild fan wrote in recently with a question or two. Ben, a backyard beekeeper in Deerfield, asks “I know there has been a lot of buzz about chemicals getting into the bee's main protein source, pollen. It would be really cool if you could mention the bees and what kind of plants the bees pollinate (and are exposed to) throughout the various seasons. Furthermore! Where in the world are the bees getting pollen in the winter? Sometimes I even see my bees bringing in pollen from who knows where on the rare warm day in the wintertime."

Is there a song that has stuck with you for years? Maybe a tune your parents sang to you as a child, the notes imprinted on your mind and became a part of your being. As Chris and Dave shared the melodies imparted to themselves, the conversation turned (as it often does) to birds. Is our musical learning similar to that of our avian neighbors?

New Hampshire is experiencing one of those few rare and special weeks right now. About 48 weeks of the year, the New Hampshire landscape is pretty homogenous; from a distance our deciduous trees can all look the same: either a blanket of green leaves, or nothing but sticks. But during a few brief weeks in the fall and in the spring – trees show their true colors. New Englanders take pride in our brilliant fall foliage season, but our ephemeral spring foliage season often passes without nearly...

Something Wild takes pride in introducing to the residents of the state to the wonder in the wild that surrounds us all. Someone who discovered that wonder at a young age is David Carroll, “I was 8 years old when I had that experience with the first spotted turtle.” Naturalist, writer, artist are among the many descriptors frequently attached to Carroll’s name.
