March is the demarcation of spring. This new season is brewing now as snowmelt percolates through the thick mats of leaves on the forest floor into swollen creeks. Sap is rising in the sugar maples (Acer saccharum), with its promise of sweetness after a harsh winter. The purple, mottled crowns of skunk cabbage (Symplocarpus foetidus) peek out of the thawing mud, surging toward the sun. And the quiet of winter is replaced with the cacophony of western chorus frogs (Pseudacris triseriata) accompanied by the “peent” and “whir” of American woodcocks (Scolopax minor) in the Lake County Forest Preserves in northern Illinois.

Yes, it’s almost that time of year. American mink (Neovison vison) mating season. I know, I’ve been waiting for it, too. February is celebrated for human romance: fancy dinner dates, shiny gifts, and long walks on the Des Plaines River Trail. But it’s useful to step out of our human-focused perspective once in a while. And thanks to our comprehensive Wildlife Monitoring Program, we know minks live in the Lake County Forest Preserves in northern Illinois. So, let’s examine why humans aren’t the only species that looks forward to February 14.
