Love is in the air! While shoveling snow, it seems a bit ludicrous to say “spring has arrived”, but here it is! I first noticed it 3 weeks ago when a burst of house finch tumbling notes filled the vapors. That was followed by a robin dusting of some rusty phrases which will soon be heard across the mid-latitudes of N. America.
What is one to think of such outrageous behavior as the snow continues to fall and the thermometer dips well below freezing? In one word-testosterone! This magical chemical is surging once again entirely dependent on the ratio of daylight to dark which has changed to such a degree that life helplessly submits to the urge for love.
Even plants are getting in the mood due to hormonal change in response to increasing length of daylight. If I were still teaching science at Logan High we would be tapping a spile into a box elder tree to catch the dripping sap and boil down on the Bunsen burner to delicious maple syrup. When we began this activity 32 years ago March was the month. It gradually changed to mid-February as the winter season shortened.
I’m guessing the tiny pink flower of stork’s bill geranium and yellow of biscuit root is already blooming beneath the snow on south facing slopes. Death camas leaves are beginning to poke through moist soil.
Snow geese and tundra swans are beginning to populate our open waters with sandhill cranes and many other species of waterfowl soon to follow.
In the heavens you may see golden eagles performing their talon locked tumbling courtship death plunge, and paired ravens cavorting in mid-air. Outrageously beautiful Mountain bluebirds begin decorating fence posts in the countryside. Clark’s nutcrackers are beginning their migration to ridgetops for nesting activities.
Great horned owls present a special case. Their hoots reached a fevered pitch during their January courtship period. Nesting begins in February but no nest building needed. They take the easy out by occupying other raptor nests, especially red tail hawks, crows, or a handy ledge. They are fierce defenders of their young and have caused injure to clueless humans who approach to near. The family unit will remain together into the fall season.
Coyotes and fox are in full courtship mode showing overt affection. Parents of both of these wily canids help with den preparation and rearing pups born a few months later. Both are common in native legends for the cunning and trickery.
“If the day should ever come when one may camp and hear not a note of the coyotes joyous stirring song, I hope that I shall long before have passed away, gone over the Great Divide.” Earnest T. Seton, American naturalist, author, activist and father of the Rocky Mountain N.P.
