Winter

Give a Hoot

Feb 24, 2012

Barred owls, New Hampshire's most common owl species, also have the most familiar courtship and territorial song—usually translated as, "Who cooks for you? Who cooks for you-all?" It can be heard all year, day or night, but really revs up as owl breeding season begins in late winter. Owls are early nesters. Wildlife produce their young when their primary food resource is most abundant. Mice, rabbit and squirrel populations are exploding when owl hatchlings on a continual growth spurt require...

Noisy Water Birds

Feb 9, 2012

Summer visitors to New Hampshire typically are eager to hear the call of a common loon, emblem of the wild and remote north woods. Popular souvenirs to take home include coffee mugs, sweatshirts and jewelry—all with a loon motif. In addition to their striking appearance, I suspect the fact that loons chorus at night adds greatly to their mystique. Loons of winter don't get much attention, but scan coastal waters and chances are good you'll see a loon or two offshore. New Hampshire's breeding...

Antlers in the Snow

Feb 3, 2012

While following deer trails in snow you'll find pellets of scat and tufts of hair – coarse grey and white hair, hollow in cross-section. A more coveted souvenir are " sheds ” – cast-off antlers. After breeding ends in December, deer antlers loosen at the base. Once-formidable weapons of territorial defense drop with testosterone levels in January. The shed antlers cast by bucks and bull moose each winter are often promptly buried by snow. Hunting "antler sheds" is increasing in popularity....

I Hear You Knocking

Jan 27, 2012

New Hampshire Audubon's annual Backyard Winter Bird Survey is coming up: the second weekend each February. Three woodpeckers common statewide are among the early birds when it comes to loudly proclaiming territory and courtship. Lend an ear this time of year and you'll hear the rapid-fire drumming of powerful bills on resonant deadwood. Vocally challenged, woodpeckers drum while most other backyard birds sing. There's no mistaking the drumming of pileated woodpeckers, largest by far, booming...

Got Snow?

Snow - or a lack thereof - is a perennial January conversation. We put online Doppler radar maps in motion to access a range of snow forecasts. For people, weather news underlies commuting times, power outages and snow sports that drive winter tourism. But for wildlife, winter weather spells survival or death for animals best-adapted to changing conditions. Which animals win or lose during an open or low-snow winter? Mammals with varying pelage - snowshoe hares and a diminutive and ferocious...

Friday the 13th

Jan 13, 2012

Once again, Friday the 13th is at hand, one of the most abiding superstitions despite little agreement about its origins. Superstitions date from a time when the workings of the physical world were unknown. Calamitous events such as earthquakes, solar eclipses, plagues and death seemingly came out of nowhere. Many superstitions centered on birds, most likely because they fly high to the heavens where the gods were thought to hang out. Birds were seen as carrying messages from the gods, and...

Solid Water

You learned a remarkable property of H2O back in High School chemistry. Remember ? Normally, the density of compounds decreases as temperatures increase and molecules spread out. When temperatures fall, density increases as molecules become more tightly packed. Not true for ice – in fact, the exact opposite occurs! In liquid form, each water molecule’s hydrogen is bonded to 3 other water molecules. In ice form, each molecule’s hydrogen bonded to 4 others. These hydrogen bonds form an open...

A favorite children’s book I loved when my kids were young was The Night Tree by Eve Bunting. First published in 1991, the now 20-year-old story relates how a young family drove to a forest on a cold December night to decorate a living Christmas tree with edible ornaments for wildlife. The story and luminous illustrations capture the spirit of holiday giving and a special ritual in a cherished place. At home, we adopted the custom of decorating a balsam growing in our backyard with natural...

For wildlife, it's time to display winter survival adaptations … or a lack thereof. What strategy will you choose? Your options to deal with winter are limited to five basic strategies: #1) Die - Annual plants and many adult insects die-off, leaving offspring as seeds, eggs or larval caterpillars or aquatic nymphs. People avoid this strategy; too radical. #2) Don't live here - Leave . Songbirds, hawks, waterfowl, several bats, monarch butterflies and resident human "snowbirds" migrate south...

Naturally Curious

The natural world quiets down in December, both visually and audibly. Fall's riot of colors is long gone, and the bird song chorus is a distant memory. Not everyone embraces winter, but there is a positive way to view the impending season of cold, ice and snow. Without the overload of spring, summer and fall distractions, we're freed up to notice and appreciate the subtle winter world. A skilled guide helps, and for that guide I recommend a book by Mary Holland, a naturalist from Vermont. I...

November is breeding season - also called “rut” - for deer. In NH, the white-tail deer population is estimated at 85,000 statewide. Deer now occupy two social groups: family groups of female “does” with their fawns or in groups of rival male “bucks.” Deer establish a scent-based chemical landscape during the rut when male territorial behavior peaks. Bucks rub antlers against supple saplings scraping bark from bow-shaped maples or small conifers to remove the antler “velvet” and to deposit...

Beavers

Like other species in North America, the beaver suffered when the Europeans arrived, but they've staged an impressive comeback.
