Behind the bandit mask

Post by Brett Peto

You know them as raccoons (Procyon lotor). Though maybe trash pandas is more your style, a phrase that’s taken off since it first appeared on Reddit in 2014. (I can’t help but note the Rocket City Trash Pandas, a Minor League Baseball team, plays ball in Madison, Alabama). Or you could even know them as washing-bears, an old Germanic nickname bestowed on the species “because they have a habit of rinsing and softening their food in water before they eat it.” This moniker actually has a connection to the legendary naturalist Carolus Linnaeus, who created the Latin-based binomial nomenclature system and originally labeled the raccoon as Ursus lotor (“washer bear”). Whatever you call them, raccoons are commonly found in the Lake County Forest Preserves in northern Illinois.

It’s easy to spot one, of course, by its bandit mask: the patches of black fur bending below each of its eyes. This mask is nothing short of iconic, but it’s likely an icon with a purpose: “one hypothesis for the dark fur is that it may help reduce glare and enhance the nocturnal animal’s night vision.” There’s more to know, though, about these medium-sized mammals beyond face value—or just one feature of their faces.

The solace of purple martins

Post by Jen Berlinghof

There’s solace to be found in the fact that the rhythms of nature march on. This spring, the sun still rises. The wild leek (Allium tricoccum) still pulses its verdant green arms through the pulpy leaf litter of the forest floor. The birds still surge through the skies as they migrate to and through the Lake County Forest Preserves in northern Illinois. Like us, some of these birds are inclined to congregate in large communities. Over the years, the colonies of a particular species, the purple martin (Progne subis), have become largely reliant on people to provide shelter for their nesting flocks.

Get to know groundhogs

Post by Jen Berlinghof

Late last summer, I literally watched a groundhog (Marmota monax) fatten up before my eyes. He’d made a burrow in the field outside my office window and frequently visited the rain gardens around the Edward L. Ryerson Welcome Center in Riverwoods, part of the Lake County Forest Preserves in northern Illinois. We watched him scamper back and forth, snipping flower tops here and there, always with a mouth crammed full of flora.

Fast forward to early February, and as I look out across the same field, now dotted with small snow drifts punctuated by tufts of grasses gone tawny, I think about that groundhog curled tight in his burrow and deep in hibernation, oblivious to the hubbub of a day in his honor.

109 adopted turtles!

Donations poured in from Lake County and beyond (as far away as California!) to adopt baby Blanding’s turtles, allowing us to continue our head-starting program and field work next summer.

A beautiful invasion

Post by Kelsey Roehrich

I am a student at Iowa State University, and traditions are an important part of school life. One long-standing tradition centers around two swans, Lancelot and Elaine, which float on a small campus lake. Legend has it, walk around the lake three times with your significant other and you will be together forever, since it is said that swan pairs mate for life.
