Vestigial Remnants of Hibernation?

It is frigid outside and has been for a long time.  It is very cold in many parts of the country.  The holidays have come and gone.  The hoopla of the inauguration is over.  Now begins the nitty-gritty of hard winter work.  I find myself listless and not wanting to go outside or exercise or paint or take pictures or do much of anything I usually love to do.  I have a cold but that does not excuse this lassitude.   When I go to my favorite deli, I find that Terry, the sandwich lady, is in the same mood.  “I was ready to go home the moment I came in,” she says.  My husband was dour and I was sour.  What is the meaning of this discontent?  Could it be some vestigial remnant of human hibernation?  While man has never hibernated, science finds his metabolism slows down in winter and he becomes less active.  Binging on food and drink over the holidays may not be the sole reason for weight gain in winter.  Perhaps we should be sleeping off the extra pounds.

I who love winter and live for fall each summer, find myself longing to hear the music of the spring peepers.  It is months away– well about a month and a half away.  They signal for me the first harbingers of new life.  Terry, who also loves winter, tells me today she is sick of winter as she makes our sandwiches.  Perhaps it is this string of Arctic air and grey days and icy road conditions and snow every few days.  Perhaps, and more likely, it is the human condition to always be dissatisfied.

 I miss the squirrels.  It has been so cold and snowy they seem to be laying low in their nests.  Judging from the tracks in the snow the animals most on the move are the deer.  And as much as I love the silence of winter, I find myself longing for the sweet dulcet music of birdsong at mating season in spring.

We bought a calendar for the new year with a celestial map of the sky for each month so you can find the constellations in the night sky.   We have yet to go out with flashlights and match the map with the canopy of stars.  It has been too overcast or too cold or too something.  But my dazzled psyche is humbled by the view of the stars through the stripped down trees that we see from bed every night.

Then again maybe it is laziness.  Too many sugar highs in December have led to a deep low in February.  And after a tease of spring one day in which the temperature reached almost 60 degrees we were let down even further.  Not liking being unproductive, I think I can overcome this.  But maybe I should just go with the flow and accept a period of inactivity, let the land lay fallow, so that an increase in productivity may eventually result.

I know I should focus on what is positive.  Winter is the season of silent beauty that I so long for in the summer heat. I delight in the quiet of winter days.  The snows bring a hushed stillness good for the soul.  It is a time to regroup.  Spring will come.  Hopefully if man has not destroyed all the vernal pools, the spring peepers will return.  And if pesticides have not destroyed all the birds, sweet mating songs will be sung.  And if the weather turns more clement, our spirits will soar once again, and we will be busy bees making honey while the sun shines.

The Edge of Winter

P1050266_edited-2It is an overcast day.  Brightly colored birds stand out like jewels in the greyness.  The sparrows blend into the wooded grey/brown of snow-covered shrubs.  The ever-present sparrows and the  winter birds– jays and cardinals, juncos, black-capped chickadees, white-breasted nuthatches and downy woodpeckers– flock to the bird feeder which now has to be filled up almost every day.  The red berries on the bushes are nearly all gone and the feeder is becoming a matter of survival.  On our walks we see empty nests held in the bare arms of winter trees.  An empty robin’s nest is filled with snow– the hatchlings and the mother long gone to fairer climes.  The trees are stripped down to their souls.  With ice storms they become tinkling chandeliers.  In the rain the few remaining dead leaves drip drops of icy tears.

Occasionally a dove visits the feeder.  The chipmunk, who gathered scattered seeds under the feeder all fall, is not to be seen.  He must be in torpor in his den.  According to Bernd Heinrich in: The Winter World: the Ingenuity of Animal Survival, the eastern chipmunk builds a twelve-foot storage system with a nest chamber some three feet down and a network of tunnels which includes a food storage chamber.  Heinrich says chipmunks go in and out of torpor.  He reasons that they would not gather food if they were to be in torpor all winter long.  We will probably not see our chipmunk for the rest of the winter for, in his stuporous state, he would be easy prey.  However he can be roused to eat and venture outdoors if need be, especially in March when there still may be snow on the ground but mating season begins.

The grey squirrels are busy clearing snow from branches as they run along tree limbs.  On the ground they dig through the snow for the walnuts we watched them bury in the ground with their noses this fall.  They do not need to hibernate for they have food stores which they built up in the autumn– and leafy, well-insulated nests.  The red squirrels survive winter by putting on thick, insulating fur.

The back yard is a maze of tunnels.  We think they are deer mouse tunnels as many have tunneled their way into our house.  But they must get by the feral cat who sometimes waits out a snow storm under our deck.  In the woods, the occasional deer waits out the same storm under a squat fir tree. The tracks in the snow tell the story of how they weathered a Nor’Easter.

Beneath the tracks in the snow, in the frozen leaf litter, the insect world is dormant.  Some hibernate.  Others fill their bodies with antifreeze, glycerol, to stay alive.  Heinrich talks about  woolly bears hibernating but they are also capable of freezing solid and surviving, coming to life again as they thaw in the spring.  The pupae, however, don’t survive being frozen.

In Winter: an Ecological Handbook, authors, James C. Halfpenny, Elizabeth Besiot and Roy Douglas Ozonne, tell us that the reptiles and amphibians pick out a “microclimate for hibernation that does not freeze” for their winter, such as the “bottoms of ponds, streams, or deep in the ground.”

Our stream flows out back in the marsh under ice and snow and one can see the elongated bubbles of running water.  In the pond next door the turtles lay beneath the ice in their hibernacula.  At the end of the book, The Year of the Turtle, David M. Carroll, the naturalist, author and artist, has his watercolor of a spotted turtle hibernating.  This picture is hypnotic and in its spell, I think of all the animals hibernating beneath our feet in lugubrious gloom.  It reminds me of the penguins in the film, The March of the Penguins, huddled together for warmth in the harsh, strong winds and snow, taking turns being on the outside of the huddle.  Winter can be magnificent in its transformations yet tragic in its harshness.  Hibernating animals who freeze to death and deer starving in the snow are among the victims of its violence.

Carroll’s drawing shows the turtle all alone, withdrawn into its shell under less than two feet of water, lodged firmly in the mud under ice and under snow on a sunny winter’s day, a far better clime than the penguin’s–  and yet it evokes a certain sadness for this little creature all alone beneath the snow, in a torpid state.  The turtle is missing out on the days and nights, sleeping a deep sleep in a “half year of stillness.”

Carroll’s writing is sheer poetry as he describes the turtle’s hibernation: “Mounting layers of snow silently cover the ice.  Night after night in the harshest depth of winter, as Orion and the Pleiades burn distant and brilliant in the black sky and strong winds howl off the mountain to the northwest, the turtles rest beneath the ice.  With the life in them nearly suspended, reduced to its most tenuous hold, all but extinct in the vast, inhospitable regime that reaches above them to the limits of the universe, they lie within their shells, waiting for the earth to make its required turnings and return them to the sun that will awaken them to another season.”

I think of the turtles below, along with all the other beautiful creatures, and wish them a kind sleep from which they will safely stir as the life force surges through their veins again when the sun brings them to the fullness of life in spring.  The death of some, and the half-life of so many, proffers the poignancy of winter.
