Nature Notes

Spring – In a Different World

Editor’s Note: We know that staying connected to nature is important, especially as we cope with a global pandemic. Since the Arboretum is temporarily closed to visitors (including walkers), our Minnesota Master Naturalist volunteers are finding other ways to share their observations of the natural world. We wish to open our gates to public soon, but until then, we hope you are all finding ways to enjoy nature.

Tiny sprigs of green

The very beginning of spring is usually a celebration for me. I head outdoors to enjoy milder temperatures, longer daylight hours, and hopefully some sunshine. Each tiny sprig of green popping through fallen leaves and dried stalks is a cause to rejoice at their return.

But the joy is muted. Many people worldwide have passed away from the sudden coronavirus, and our community is taking huge precautions to mitigate its spread. Like my employer, the Arboretum, too, is closed to protect employees and the public alike. So, I head to areas close to home for my springtime nature fix.

Red-winged blackbirds

And I’m glad I did – the birds are returning, now, too! Red-winged blackbirds – just the males for now –spread their wings to display red and yellow shoulder bars while calling raucous “konk-la-REE!” to claim their turf. I once saw someone sit, unaware, near a nest. She wore a black beret with yellow and red patterns. The red-wings dive-bombed her until she moved away!

Along Minnehaha Creek, I stop in my tracks at the sudden sound of thrashing in the wetland. My friend thought she heard turkeys gobbling. No – it was a pair of sandhill cranes barely visible through the cattails. One flapped its wings high, then both called their tremolo bugle calls. You can hear their unique song at the Cornell Lab or Ornithology’s All About Birds website: https://www.allaboutbirds.org/guide/Sandhill_Crane/sounds. And find a great bird identification app from Audubon Society, as well as many other nature pursuits to help ease our days in the sidebar below.

Hepatica leaves

Hepatica leaves have popped above leaf litter. Their flowers bloom before the leaves appear, so these must be last year’s leaves, which usually last through the winter.  Soon tiny flowers in pastel shades of pink, violet and white will appear, just several inches tall.

Stream ice is melting and lakes are dotted with open water, beckoning winter’s dabbling ducks and fish-deprived birds. Ring-billed gulls float in groups while mallards paddle past. Canada geese are ashore, some napping with their heads tucked under a wing.

A juvenile bald eagle lands on the ice and peers into a hole. A crow that had been fishing at that hole earlier stood bravely less than a foot away, waiting for its turn. The crow probably didn’t notice the adult bald eagle about 50 yards down the lake as it squawked at the young eagle.

Wooly bear

A short woolly bear, the larva of an Isabella tiger moth, sits right on the gravel path! Others on the path are careful to walk around it, but we all still maintain the requisite six feet of social distance between us. People speak in low voices, smile and nod as I walk past. But everyone seems subdued as we all face the realities and unknown future that coronavirus has brought.

I hear the woodcock is doing its annual and amazing flight displays down at the Black Dog Unit of Minnesota Valley National Wildlife Refuge. At least nature is still the same.
