Enjoy the hooting season

In February, sensational sunrises and sunsets break up the stark days and cold, dark nights of a waning winter. Dawn and dusk not only bring the thrill of color to a monochrome landscape, but also the best chance of hearing and seeing nocturnal raptors. As the mercury drops, owl courtship heats up. While many other birds head south for winter, owls pair up and hunker down. At night, the soundtrack of our resident species’ hoots and hollers fills the Lake County Forest Preserves in northern Illinois, offering us a glimpse into an otherwise hidden world.

Winter reveals hidden homes

The winter landscape, stripped of its lush layers of leaves and fields of flowers, reveals hidden homes. This season of stillness offers a glimpse into animal lives that were carried on clandestinely throughout spring, summer and fall around the Lake County Forest Preserves in northern Illinois. It’s surprising to see how many critters have been busy raising families right under our noses, or sometimes, right above our heads, without us always noticing.

How animals survive the winter

Guest post by April Vaos

Living in Illinois, we’re lucky enough to enjoy a change of seasons. Though I often find it difficult to switch from the crunch of fall leaves to the crunch of snow, it can be a peaceful time to head outdoors. Recently, I went walking in Independence Grove in Libertyville, part of the Lake County Forest Preserves in northern Illinois. As I looked around in the quiet, contemplative landscape, I thought about the life that teemed all around me, and how it was now hidden from view or departed on a migration.

While leading winter walks, I’m often asked, “Where are all the animals?” It depends on the animal. Each employs different survival strategies that help it adapt and even thrive in winter. What, exactly, do animals do to make it through the challenges of cold temperatures and a lack of food? Well, I like to say they have MAD strategies: migrate, active and dormant.

When cool temperatures arrive in northern Illinois, so do dark-eyed juncos (Junco hyemalis). Not only do they visit Illinois, they migrate into all of the lower 48 states to spend a milder winter than where they’re from: Canada. Stock photo.

Go take a hike

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.

Leopards and tigers and bears!

Around the first frost is the best time for spotting bears in the Lake County Forest Preserves in northern Illinois…woolly bears, that is! These fuzzy caterpillars succumb to a late fall wanderlust and can often be found traversing trails and roads, as well as climbing vegetation and nibbling a last few bites before winter sets in. They belong to the subfamily Arctiinae, commonly known as tiger moths. Their scientific name stems from the ancient Greek word arktos (“bear”), for the appearance of their hairy larvae.

Happy Winter from the Lake County Forest Preserves!

Whether venturing outside for fresh air and exercise, or finding a gorgeous spot to sit quietly and reflect on the past year, we find great peace in the Lake County Forest Preserves.

Thank you all for following along on our adventures this year. We encourage you to find a quiet spot to just breathe—perhaps the still woodlands of Captain Daniel Wright Woods:

Cheers to a new winter and peaceful new year!

My family and I spent the beginning of the new year in the Northwoods. We wanted quiet. We wanted nature. Most of all, we wanted snow. As we started out on a snowshoe trek to a nearby river, tiny snowflakes settled on my son’s navy blue parka. They seemed to freeze on contact for only a few seconds, forming miniature constellations, before melting into temporary teardrop stains. The filigree of each flake in those hushed, fleeting moments fascinated both of my boys.

Nature at night

This winter’s lack of snow has made enjoying the winter woods a little more difficult for me. So, when a scant few inches of snow fell last week I made my way to Old School Forest Preserve at dusk to explore one of the Lake County Forest Preserves solar-lit trails.

Inky black branches of old oaks played in contrast to the white-washed sky before the blush of an orange sherbet sunset took over. The woods were still and quiet as I searched for any signs of crepuscular creatures that capitalize on the twilight. Continue reading →

Des Plaines River Trail—Route 22 to Lake-Cook Road

It was a new year and a new trail, as we completed the last leg of our Des Plaines River Trail journey to hike the entire length of Lake County, Illinois. We began this hike just south of Route 22, which led us south through the recently completed trail section and beyond to the southern border of the county. We left our tracks upon the trail, just as the animals do along this greenway. Along the way, we found fresh signs in the snow that mice, squirrels, small birds, raccoon, deer, fox and even some intrepid fat-tire cyclists had all traversed the trail before us, taking advantage of a balmy 40-degree day in January.

Stories in the snow

Post by Jen Berlinghof

As the thermometer dipped to -8 degrees Fahrenheit this week, one thing was clear: the snow and cold are entrenched for a while longer. So are the stories of the animals, as told by the tracks etched in the frozen landscapes that sweep across the Lake County Forest Preserves. We may not see the animals themselves. However, each track, pile of scat, bit of hair clinging to a branch, hole in the snow and chewed acorn is an element of the tale from their winter excursions.

How do we decipher these stories? When trying to identify which animal made a particular track, it is important to look not only at the individual track but the overall pattern. Also, scan the surrounding habitat for clues.

Let’s see if you can figure out what happened in each of these nature vignettes:
