Motus captures migration in motion

The back-to-school season in early fall brings restlessness and routine to my house. I’m struck by how it parallels the flurry of fall migration across the natural world: a return to the patterns of movement ingrained over generations.

At Ryerson Conservation Area in Riverwoods—part of the Lake County Forest Preserves in northern Illinois—I observe ruby-throated hummingbirds (Archilochus colubris) tucking their heads quickly in and out of crimson cardinal flower (Lobelia cardinalis) blooms, fueling up for long flights across the Gulf of Mexico.

Green darner (Anax junius) dragonflies skim the skies by the dozens along the lakefront at Fort Sheridan in Lake Forest, their wings glittering. Fields of bee balm (Monarda didyma) along the 31.4-mile Des Plaines River Trail quiver with monarch butterflies (Danaus plexippus) nectaring to gear up for their epic journey. And, sporting less vibrant feathers than in the spring, migratory birds take flight in muted autumnal tones, heading south. As the sun sets in September and the harvest moon rises, this silent surge of fall migration commences.

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.

This year marks the 30th anniversary of the Lake County Forest Preserves’ popular Halloween Hikes at Ryerson Conservation Area. This event is a witch’s potion of sorts: a dash of theater, a drop of night hike, a splash of environmental education, and a heap of old-fashioned family fun. Continue reading →

Hordes of hummingbirds

For me, most days on the job consist of time in my “office” outdoors—a woodland, prairie or wetland in the Lake County Forest Preserves—with my “clients”—students, teachers, and families interested in learning more about local nature. On those rare days spent plunking away at a computer indoors, the photo above is my view. Recently, this view is bustling with activity, as hordes of ruby-throated hummingbirds buzz around the feeders, bulking up for a long flight south.

Bluebirds are back!

Last week while I was out checking our sap collection buckets at Ryerson Conservation Area, everything in the woods seemed a bleak brown and gray. It didn’t look much like spring was on our doorstep, but it sure sounded like it with the “plink plink” of sap dripping into aluminum buckets on the sugar maple trees and the slow “peep peep” of cold, little spring peeper frogs. Then, a male eastern bluebird landed on the branch above my head. He was a vivid blue exclamation point that seemed to shout, “Spring has arrived!”

April Fools’ bird

It was a windy, but bright, April 1 this year. I was on a trail at Ryerson Woods with a group of volunteers. Most of our heads were focused downward, inspecting the minutiae of a bloodroot bloom. Then, someone shouted, “EAGLES!” I truly thought the next thing shouted would be “APRIL FOOLS’!” but when we snapped our heads skyward, we saw two ivory-headed eagles swooping back and forth above the trees. No joke!

Slippery spring saga

Post by Jen Berlinghof

It was late March, fourteen years ago, when I took my first hike at Ryerson Woods. The air felt heavy with thawing snow. The sun warmed my back for the first time in many months. Standing at the edge of a small, glistening pool of water in this oak flatwood forest, I saw my first blue-spotted salamander (Ambystoma laterale). About the length of a crayon, this inky black amphibian is adorned with tiny, blue confetti-like spots on a dewy body. Blue-spotted salamanders hide in abandoned mammal burrows or under logs most of their life. Each spring, warming temperatures and increased precipitation lure these creatures out of their covert caverns for a slow and steady march to their breeding ponds.

Favorite photos from 2014

The end of another year is drawing near. To celebrate the biological diversity protected within the Lake County Forest Preserves in northeastern Illinois, I’ve put together a collection of some favorite images from 2014. We have such an amazing support system of photographers who donate their time and images to communicate our cause. Their passion for wildlife and the outdoor spaces our organization preserves is evident in each image they share. I hope you enjoy them half as much as I enjoyed choosing this set! Each photograph was taken right here in Lake County, Illinois.

The slideshow will run on its own, but you can speed it up by clicking on the arrows. To see more amazing images from the forest preserves, or to share photos of your own adventures, join our group Flickr pool.

Thanks for following our blog. Knowing there are others who enjoy the beauty and complexity of our native landscapes is very satisfying. Have a great holiday season!

Drought and maple syrup

With the recent snow and cold weather, last summer’s dry heat seems like a distant memory. Yet, it was only this past week that the National Weather Service officially changed its “moderate drought” designation to “abnormally dry” for most of Lake County, Illinois (although, a small northwest portion of the county is still considered to be in a “moderate drought”). While every drop of rain and flake of snow is helping to slowly ease our way out of the past eight months of drought, the damage already done will decide the sweetness of this spring.

Each spring for the past three decades, the naturalists at Ryerson Conservation Area have tapped sugar maple trees to harvest the sap and turn it into pure maple syrup.
