Extension News: February 2009 Archives

Groundhog Day represents something far more significant than a rodent predicting the weather: it's the half-way point between the vernal equinox and the winter solstice. No matter what that hapless critter does-goes back in or stays out-it still means winter is half over.

Every couple of days, I snowshoe out into my yard to feed the birds. Yes, snowshoe. That’s how deep the snow has been here in northern Grafton County. The suet has disappeared quickly, and I've replenished the supplies a couple of times.

I’ve even made my own suet "pies" to help fill the birds’ need for insulating quantities of fat by mixing the suet with black sunflower seeds. One reward for putting out hulled sunflower seeds has been the appearance of a brilliant red cardinal.

After several years’ absence, the bluejays have come back to my feeders in groups of five or six. They love the cracked corn and oyster-shell grit I put out for them. I started putting out the oyster shells after I discovered that the rat-a-tat-tat I heard coming from the front of our house wasn't a woodpecker looking for insects, but a bluejay trying to find calcium in paint.

Like all female birds, the lady jays need calcium to strengthen their eggshells, and, as it turns out, calcium is an ingredient in most house paints. I also put out eggshells from hard-boiled eggs and from raw eggs, boiling the discarded shells first in hot water to make sure they won't pass along any diseases.

In my travels around the house and garden, I've noticed tracks on top of and tunnels into and beneath the snow. These tunnels into the “subnivean” (under-the-snow) zone intrigued me. The insulating snow traps heat from the earth below, so the temperature at the interface of soil and snow remains stable, hovering just around 32 degrees, no matter how cold it is above. Often I see a little head pop up from beneath, grab some seeds and vanish back under the snow.

Mice, red squirrels, weasels, voles, moles and shrews remain active in the subnivean zone. The weasel is the predator from within, living among the creatures he will prey on. Owls and hawks watch from branches above hoping to make a meal. Patterns made by the tunnels emanate on top of the snow; try looking down to see them from a window or higher ground. Predators such as coyotes, foxes, and the owls and hawks can often sense motion under the snow and make their strikes before actually seeing the animal below.

Sometimes, I even see where tiny tracks lead across the snow surface and then just stop. Evidence of an animal airlifted by an owl or hawk and quickly eaten. No trail of blood and feathers left to tell a gruesome story, just air and snow.

Another creature that benefits from the insulating qualities of snow: the Ruffed Grouse, Bonasa umbellus. Grouse often burrow into deep snow to spend the night. When fresh snowfall hides the entry hole, an unsuspecting snowshoer may get the surprise of her trip as the grouse suddenly bursts from the unmarked snow beneath her feet.

Not only mammals, but also insects and arthropods live below our line of vision under the snow. The Snow Fly, Chionea valga, and the Elongated Crab Spider, Tibellus oblongus, not only live in subnivean airspaces, but also mate and raise their young there, often providing nutrition for other creatures under the snow. Their sources for food are often the Springtails, Hypogastrura nivicola, which New Englanders refer to as snowfleas.

Harmless to humans, these tiny members of the order Collembola exist all over the world, but here in New Hampshire they remain subnivean most of the winter and come up into the daylight, scientists speculate, to mate. They usually appear on top of the snow only when the air starts to warm a bit in late February, and then resemble black pepper sprinkled over the snow.

Winter animals don't grumble about the snow and ice, they persevere or die. The myriad ways they’ve adapted to life beneath and above the snow testify to the web of life as simultaneously wonderful, awful and surreal.

Recent research in the Antarctic has revealed prolific life existing even beneath icebergs. When icebergs “calve” from glaciers, they carry with them minerals and nutrients from the soil encased within the glacier from whence it came. This enriches the waters below the ice, providing sustenance for microscopic and larger life forms, which in turn provide food for animals in a wide radius.

Some research evolving from this source of life may help solve problems caused by global warming. There are theories that the deep oceans of our polar areas may actually serve as carbon repositories.

Whether spring returns in six weeks or less, all that life below and out of our sight may prove to be more important than we realized.

Sunday, January 7, 2009 at about 11:30 am, I spotted 30 to 40 turkeys crossing the field, across our back yard, on to our front yard and up the street. I got home in time to see them heading into the woods and up the hill, a swarm of curved dark shapes against the snow. A friend who lives at the top of the hill next to the oak forest watched them descend on her large crabapple tree still loaded with apples. The apples are gone now.

These aren't the first turkeys that have come to visit. Several summers ago we had what became almost a pet family of turkeys living in the neighborhood. One morning in mid-June I looked out the kitchen window and saw what looked like a flock of turtles at the base of a rock in the hedgerow. Dumbfounded, I stayed glued to the sight and watched the strange menagerie move across the field toward our garden. As they came closer, I realized I was watching nine baby turkeys under the watchful eye of the proud, stately mother.

They grew fast, feasting on field insects. Grasshoppers weren't a problem that summer. In about two months they grew to adult size, and it became hard to distinguish the mother among all the long necks poking above the field grasses. Although we'd heard turkeys can damage gardens, other than scuffing up some bare ground, we found no damage. But they did leave a wonderful collection of turkey feathers.

The turkeys gradually became braver, waddling right up to the house and circling about the lawn, feeding ravenously. One day in late summer, I watched in astonishment as they marched up from the garden across the lawn right up to our back patio, and hovered about the drive, gazing at the garage end of our two-story saltbox-style house. Then, with an awkward fluttering of huge wings, one flew to the ridgepole of the garage, landing near the weathervane.

Soon all nine were on the roof and proceeded to trot across the breezeway section of the roof, from which they then jumped to the peak of the main house. Next, I saw one on top of the chimney. We have a huge maple tree that soars above the house, and I was totally flabbergasted when one flew up to a branch in the tree. Cautiously, one after another, they all summoned up the courage to follow.

The last one was obviously not enthused about the idea, but finally made the leap from the roof ridgepole. They continued on to adjacent trees where they were surprisingly well hidden for their night-time roost. By roosting in a different location every night, turkeys hide from predators.

Checking the N.H. Fish and Game Web site, I learned that 25 turkeys were re-introduced to New Hampshire in 1975. Today, about 36,000 turkeys live here. If the flock of 30 really has only one tom, and 29 hens that each lay 10 eggs, with a conservative survival rate of five, we could have 145 more turkeys next summer plus the 30 parents. That’s 175 turkeys!

Obviously, they're thriving in our wooded suburban setting, with its combination of lawns full of insects, native shrubs full of berries, and mature oak forests producing nutrient-rich acorns. The pond where we saw them first is fed by small streams flowing off the nearby forest-covered hill. The stream flows all winter long, icing over only during the most brutal cold snaps.

I read that turkeys mate in March. Their nests are just hollows in grass on the ground. Hens lay 10 to 12 eggs; one a day for almost two weeks. The hens incubate the eggs for 28 days, but are sensitive to disturbances during this time and will readily abandon a nest. The poults are ready to leave the nest 24 hours after hatching. The poults I saw in mid-June must have been about four to six weeks old. The poults can fly when they are two or three weeks old; from then on they will roost in trees at night.

A New York Department of Environmental Conservation pamphlet, The Wild Turkey in New York, explains how turkeys survive the bitter winter weather:
During the winter, turkeys reduce their range, diminish their daily activities and often form large flocks. They frequently spend time in valley farm fields feeding on waste grain and manure spread by the farmers. Spring seeps, which are usually free of ice and snow, are also favorite feeding areas. When a severe winter storms strikes, turkeys can spend as much as a week or more on the roost, waiting the weather out. Studies have shown that healthy wild turkeys can live up to 2 weeks without food.

Incredible! As I write, my 30 turkeys, stuffed full of crabapples, must be roosting on tree branches waiting for the sun to break through tomorrow. That will be a sight to see.

Editor's note: To help biologists gather data on the health and distribution of turkeys during the challenging winter months, the state Fish and Game Department wants to hear from you. If you see a flock of wild turkeys flock between now and the end of March, report your sighting using the electronic survey form at www.wildnh.com/turkeysurvey. Please don't report multiple sightings of the same flock.

The “world’s worst weather” isn’t found in the Arctic or Antarctic, but here in New Hampshire on Mount Washington. I hiked this mighty mount one summer. It was thrilling to reach the summit then, and I longed to go there again in winter.

When I got an email from the Mount Washington Observatory (MWO) about winter day trips to this 6,288-foot peak, I immediately sent my money for one of the 12 trips.

Later, I leashed my enthusiasm when I read the “average mid-winter day on Mount Washington has a temperature of about 5 degrees Fahrenheit and a wind near 50 miles per hour...typical 'wind chill equivalent' approaching 25 below! Temperatures of minus 20 degrees can occur even in April! Never underestimate the severity of summit weather conditions!”

More than 100 people have died in the White Mountains, and nearly two dozen of those froze while summiting Mt. Washington. This was no spree, but an extreme experience that could lead to death if we didn’t take care. The MWO issues a 17-item list of clothes and gear needed. Cotton is a no-no, because it absorbs and holds moisture, whether from fog, snow or perspiration. Wool or synthetic wear is best.

I considered renting equipment and called Charlie Townsend, Eastern Mountain Sports climbing school director, in North Conway. “I have one of those baklavas,” I said, mispronouncing balaclava, the facial hood with eye and mouth holes. “Well, you don’t want to wear a Greek dessert on your head,” he joked. Townsend, who leads winter and summer hikes in the White Mountains, told me MWO wanted people to comprehend these hazardous conditions, and if an emergency arose, all that equipment was lifesaving.

A few days before my scheduled expedition, the Northeast was steeped in single-digit temperatures and stormy weather. I thought the trip would be cancelled, but the day dawned clear. The mountaintop temperature was 9 degrees F (minus 10 degrees wind chill), and winds were 15 to 30 mph with a three-mile visibility.

Besides high-tech underwear, I wore four layers under a heavy fur-trimmed parka, and two pairs of insulated pants. I felt bulky and moved like a turtle. There were seven of us in the snow tractor-a machine with huge, rolling blades that deeply grips the snow and ice along the road, while its front plow smoothes the eight-mile road’s snowdrifts. It’s a three-hour round trip, with several stops to view the prominent peaks and valleys in the White Mountains.

Dr. Peter Crane, director of programs, who oversees MWO’s educational efforts, told us about the history of the peak, located in the 52-acre Mt. Washington State Park. A non-profit scientific and educational institution, MWO is funded by private and corporate donations, grants and other sources. Not part of the National Weather Service (NWS), as people think, MWO is private but has contracts with NWS to provide weather data.

The highest recorded surface winds gusted at 231 mph on April 12, 1934, and the official low was minus 47 degrees. “The wild weather on the mountain,” Crane said, “is due to its location at the juncture of three major storm tracks, plus the enhancing effect of altitude.”

When we arrived at the spectacular summit, we went inside MWO’s headquarters, which it shares with the state park. After hot drinks, snacks and talk with a half dozen personnel, we suited up and climbed the observatory’s tower. I had difficulty breathing, and thought: Must be getting old. Crane and young people working there later explained most people need time to acclimate to the altitude.

Leaving the tower, we took more than an hour’s walk to the official summit top and around its historic buildings. During that time, I saw two teams of four climbers crest the mountain.

I was awed by the vast whiteness, where wind artistically sculpts rime ice (frozen fog) into sharp, horizontal points on tower wires, and snow into fanciful swirls on the landscape. Beautiful, I thought, but deadly.

I was struck, too, by the swift change from clear to cloudy skies, and back again. I would start to take a photo, and seconds later clouds obscured the view. Most days, it’s cloudy 60 percent of the time. When it’s clearest, you can see New York, 130 miles west, and the Atlantic Ocean, 60 miles east. Visible also are mountains in the Presidential Range: Madison, Adams, Jefferson and others.

Back inside after lunch-soup, sandwiches, and beans-we toured the station’s meteorological area, with Crane explaining various functions. All too soon, it was time to board the tractor for the world below.

Back on ground level, I looked up from where we had come, but clouds hid the view. Native Americans named Mt. Washington Agiocochook, meaning place of Great Spirit. In my memory this spirited mountain will never be shrouded.
