A tale of two squirrels

Post by Jen Berlinghof and Allison Frederick

Everywhere you look this time of year, animals are tending to nests during spring’s baby season. Squirrels are very active at this time with the bounties of spring. Food reserves from winter are low, and energy demands are high with young in the drey (their leafy, treetop summer homes) demanding to be fed. So, squirrels turn from their habits of digging for winter caches and begin eating buds, flowers, fungi and lichens. They will take advantage of almost ANY food source at this time of year!

In search of river otters

Guest post by Andrew Rutter

I had just finished my time as a Masters student at Southern Illinois University with the Cooperative Wildlife Research Lab, studying river otter (Lontra canadensis) ecology, when I took my first full-time position as a wildlife biologist with the Lake County Forest Preserve District in Illinois.

Having spent the last two years of my life entirely focused on river otters, I figured my time studying the species was at an end. Although my research team and I found them to be relatively abundant where we focused our research efforts in southern Illinois, I did not expect the same to be true farther north in Lake County.

Skunk stories

Post by Jen Berlinghof

Just like fish stories, it seems everyone has a skunk story to tell. I have many, but my favorite one happened a few years ago in the spring, when I was getting ready to teach education programs at Greenbelt Forest Preserve. Before the students from a local school arrived, we were busy unloading supplies and setting them out around the preserve. When we returned to the van, we found a skunk sauntering right up the open lift-gate, looking curiously like he might climb in! We froze, chanting in a hushed tone to ourselves, “Please don’t go in there, please don’t go in there.” Either our chants worked, or he realized the preserved insects in the cases he was checking out were not a good meal. He casually wandered back to the brushy field and was long gone by the time the bus arrived.

Virtual camouflage hike

Leaves throughout the forest glowed gold against a backdrop of graying sky as I left Ryerson Conservation Area yesterday afternoon. This morning—as I entered the same preserve along the same road—the dark, skeletal branches were completely visible, stripped of their vibrant leaves that now lay in muddied piles on the forest floor.

These days of November mark a change from crisp colors to muted tones, which offer the perfect backdrop for animals to hide using camouflage. Lake County Forest Preserve educators often teach the concept of camouflage during environmental programs, where students hike in search of animal hides and mounts that have been hidden along the trail. Teachers and scout leaders, peruse our variety of school and scout programs to find a great fit for your group this year. Following is a virtual version of our camouflage hike. Continue reading

“Flying” to a feeder near you?

One of our volunteer naturalists recently shared a story of an exciting discovery she made at her bird feeders. She loves to tell anecdotes about the slew of birds that frequent her backyard feeders during the day. However, this time her visitors were not birds, and they appeared in the middle of night. She had seen odd things at night when passing by the windows that looked out towards her yard: a bird feeder swinging wildly with no wind and shadows cast by the moonlight that moved in a herky-jerky scuttle up  nearby trees. It wasn’t until one night this winter, with the flick of a light switch, that she caught these mysterious critters in action: Continue reading

The winter world of cottontails

Now that the icy days of January have arrived, everyone in my house has that cooped up feeling and needs to get outside for a view of the expansive winter sky. We need to breathe a bit of fresh air, regardless of how cold it might be. At dusk, my sons and I have been hiking a nearby trail that takes us through scrubby meadows and thickets. During these forays, the boys are often loud and boisterous—until they flush out a cottontail rabbit. They quickly hush. We spend the rest of the hike searching for “our” rabbit (or signs of it) as we crisscross the worn network of trails trodden with tracks.

Chipmunk song

Last week as I was leading a group of adults on a fall color hike, our collective gaze turned quickly from the canopy of coppers and golds to the forest floor as we watched the flurry of chipmunk mischief unfold. We huddled around, marveling at the energy of these charming rodents.
