At first glance, a prairie doesn’t look like much in early spring. Some might even go so far as to say it’s nothing so much as a bunch of dead weeds.
But look closely, take a long, leisurely walk through Midewin, and you’ll see the joint is really hopping, buzzing, chirping and bellowing with life.
At 19,000 acres, Midewin is big and diverse enough to harbor an exceptional diversity of birds. Over the past several years, I’ve seen 125 different species at Midewin. Today, as resident and migrant species return, I’ve seen 46 species, including brown thrashers. Typically, they are solitary and secretive. A fleeting glimpse is mostly what you can expect before they disappear into a thicket. Except in early spring, when they perch in yet-leafless trees to sing their melodious mating calls, while keeping a wary eye on the world.
Black-capped chickadees hang around Midewin all winter long, but it’s in spring that these tiny bundles of energy – weighing about a third of an ounce – really get busy, harvesting every nook and cranny for seeds, insects and spiders, while filling the air with insect buzzes, major fourth call notes and their namesake “chick-a-dee-dee-dee.”
Particularly thrilling is spotting a loggerhead shrike. Midewin is home to a handful of breeding pairs of this state endangered and proposed for listing as federally threatened species. In addition to their rarity, they are notable for caching prey – insects, rodents, even other small birds – on thorns, of which there are plenty at Midewin with all of the osage orange trees remaining from its pioneer past.
On one of the warmest days thus far this spring, the warm-blooded creatures of Midewin – me included – are not the only ones enjoying the welcome sunshine. To survive the winter, garter snakes go into hibernation (technically brumation, in that being cold-blooded – technically, ectotherms – they remain alert but sluggish, the cold slowing their metabolism to nearly zero, which means they can go long periods without eating but not starve.) When the temperatures warm, up goes their metabolism and they must reemerge to feed. On the other hand, who doesn’t love basking in the sun after a long winter?
So, too with green frogs and painted turtles.
High summer is when the prairie is ablaze with more than 200 species of grasses and flowers. But in early spring, Midewin’s Prairie Creek Woods harbors a host of woodland ephemerals, such as this swamp buttercup, in turn hosting one of many different kinds of native bees.
As with every season, there is always a little sadness. This fledgling painted turtle apparently tried to leave its nest and make its way to a wet area, but ran out of energy on the gravel path.
But this death also provides an opportunity to take the kind of closer peek at the beautiful underbelly of a painted turtle, something you almost never get to see by observing critters in the wild.
Something else you seldom see are duck nests. Unlike mallard drakes (males) that boast metallic-emerald green heads, the hens (females) are dull, streaky brown, the better to blend in with their ground nesting environs. Clambering atop one of Midewin’s old arsenal bunkers for a panoramic view of the landscape, I inadvertently flushed a hen from her nest, which was nestled against the bunker’s exhaust vent.
At the other end of the animal spectrum, Midewin has officially welcomed its first baby bison. I don’t have pictures yet, but stayed tuned. Better yet, head out to Midewin yourself. A big, beautiful prairie and all the life it harbors awaits you.
