Give thanks for turkey vultures

Post by Jen Berlinghof

Come late November, most of us have turkeys on the brain. But a different type of turkey is taking to the skies at this time of year on its annual migration south: the turkey vulture (Cathartes aura). You can spot them in the sky or on the ground in the Lake County Forest Preserves in northern Illinois.

Go take a hike

Post by Nan Buckardt

Everyone has one! At least, anyone who regularly hikes in the Lake County Forest Preserves in northern Illinois has one: a favorite trail. It might be the trail near your home or the one that reminds you of a secret only-I-know-about-this spot growing up. Maybe it holds a special memory. Whatever the reason, something about it always sparks joy in your heart.

I’ve been thinking about trails a lot this fall as I’ve hiked those selected for this year’s Hike Lake County (HLC) program. HLC has encouraged folks for 20-plus years to explore seven of 12 designated trails between mid-August and November 30. More than 200 miles of trails thread through dozens of preserves countywide, so the diversity of choices isn’t necessarily a big surprise, but it is a big benefit to residents and visitors.

A different kind of autumn apple

Post by Jen Berlinghof

Fall is the time of harvest here in the Midwest. Golden stacks of hay bales, farmer’s markets teeming with end-of-season produce, and above all, apples. But step away from the orchard and into an oak woodland and you’ll find a different kind of autumn apple: an oak apple gall. What looks like a small, lime-green, spotted apple dangling from an oak leaf is not a fruit at all, but rather a secret abode for a tiny wasp.

There are more than 50 species of oak apple gall wasps in North America. Each one creates a unique fruit-like structure that protects and feeds its eggs and larvae as they develop. Lately, I’ve been finding many dried, spent brown husks created by the larger empty oak apple wasp (Amphibolips quercusinanis) around the Lake County Forest Preserves in northern Illinois.

The din of the dog days

Post by Jen Berlinghof

The dog days of summer are a bounty for the senses. We see the lemon-yellow of whorled sunflower blooms, taste the ripe flavor of a homegrown tomato, smell the spicy sweetness of bee balm flowers, feel the heat of the day and the cool of the evening. Yet the most quintessential sensation of these end-of-summer days is hearing the overwhelming cacophony of cicada songs around the Lake County Forest Preserves in northern Illinois.

Monitoring in the morning

Post by Brett Peto

Good things start at seven in the morning. That’s when our group of four hiked 15 minutes off-trail into the heart of Middlefork Savanna in Lake Forest, part of the Lake County Forest Preserves in northern Illinois.

The air was warm, the sunshine spread everywhere. Spiderwort blooms were freshly open, a waist-high meadow of bluish-purple fireworks. We found the steel T-post marking the start of the day’s first transect and the red flag for the first plot.

Then we gathered our tools. A one-meter-square collapsible wooden quadrat, retractable tape measure, clipboard, data sheets, and each other’s knowledge of plants.

Well, my own knowledge, not so much. I was there to take photos and observe the three experts onsite: Pati Vitt, Manager of Ecological Restoration; Ken Klick, Restoration Ecologist II; and Pete Jackson, who authored a 2009 study on this preserve’s plant communities that served as his thesis for a master’s degree program. In my head, I called them the Plant Team.

A world of warblers

Guest post by Alyssa Firkus

In my early twenties, I believed adventure was found in the tallest mountain, the deepest ocean, the largest cavern. I chased whales, orca, brown bears, bald eagles, and other charismatic megafauna. It took decades to realize I didn’t need to seek these animals or climb these mountains to find adventure. Some of the best adventure awaited me in my own backyard. This led me to join the Education Department at the Lake County Forest Preserves in northern Illinois in October 2018. What an adventure it’s been!

Anyone who’s attended a program taught by our staff or volunteers knows these educators are knowledgeable and passionate. This group ignited my latest adventure—birding—though I can’t point to a single component that sparked my newest hobby. It could have been my awe for the birders in this group, their love for birds and their impressive ability to bird by ear. It might have been my draw to a new challenge. The patience, attention to detail, and dedication it takes to be an effective birder. It may have been the rush of excitement, getting a glimpse of a rare species for a brief moment as it makes its annual migration. Perhaps all of these were feathery factors. Regardless, I’m hooked.

Birding is a rewarding activity that requires patience and knowledge. Photo © Tim Elliott.

The wonder of wood ducks

Post by Jen Berlinghof

Spring is the starting block for wildlife in the race to find suitable mates and nesting sites. With the increased flurry in wildlife activity, staff at the Lake County Forest Preserves in northern Illinois also get an increased flurry of phone calls with questions from the public. One recent call came from a gentleman in disbelief upon seeing ducks perched in his trees. He was utterly transfixed by the phenomenon. The call brought back a flash of memory for me of the first time I saw a wood duck (Aix sponsa) as a child, on my maternal grandfather’s property in northern Illinois. Grandpa “Duck,” as we affectionately called him, was an avid outdoorsman. He spent a few moments that spring day pointing out the distinct, vibrantly hued male and the more muted female near a nest hole in an old maple tree. The pair then took off into the woods to the soundtrack of their high-pitched whistling calls.
