Much of the natural life in the city of Chicago is happening in fringe areas. Certainly wildlife use the city parks, golf courses, and cemeteries as both homes and byways and the arteries of our city, the train tracks, the river and the expressways and the scrubby land around them also provide spaces for animals to live and travel.
I have spent most time in areas bordering the Chicago river. Even though parks, houses and industrial parks back on to this waterway, and the river, though much improved, would not be considered clean by any imagination. Animals find homes and passage on the river. Several major parks have now set aside natural areas where a city park gives way to some native plants and paths along the edge of the park. In Horner Park ,south of Montrose Avenue, this takes the form of a new nature area along the river, with paths and native plants. North of Lawrence it follows Ronan Park and River Park past the sewage treatment plant along the north branch of the Chicago river and becomes the North Shore Channel trail. Popular with bikers and dog walkers and runners close to the river it is still a haven for blue herons and black crowned night herons, migratory warblers and small mammals, the passing coyote or skunk.
On Saturday I spotted the young American Opossum above not more than 10 yards from busy Lawrence Avenue (pictured above). It remained calm, almost completely unobserved from its perch in a small tree as dog walkers and a cross-country skier, pedestrians and countless cars zipped past unseeing. (Below, view of Horner Natural Area from the Lawrence Avenue bridge).
Nature fills the available space along this little islands and rivulets of green that pepper the city. Even if I don’t venture to a forest preserve I can count on seeing wildlife if I am willing to go to the river and wait.
The river itself is filled with turtles, mallard ducks and Canada geese and the seasonal outlier, a showy red breasted merganser, a common goldeneye duck diving for food or a red-tailed hawk watching for prey. I once stood well into dusk on the Wilson bridge and watched a pair of American beavers climb the bank, pick choice branches from a backyard hedge, carry the branches back to the river and strip them bare. Around humans and in spite of us, they have found and filled the gaps we have left them. (American Beaver on the Chicago River below).

Other writers have written of “edgelands,” the places where the city gives way to wilderness amidst a jumble of the detritus of humans and almost wilderness. These narrow patches within a city are even smaller and it is worth taking the time to explore them.
I am often asked by friends who follow my photography where I go on the weekends to see all this wildlife and they are surprised when I tell them it is in the city and often not even in a nature preserve but the dead-end of a street by the river. Discovering nature in a city is about being willing to look for it and listen for it in the most unexpected places until you know where and how to see it. I was walking with a friend in Hyde Park and almost automatically when I heard a call said, “Oh that’s a cardinal.” Then looked until I spotted it on a nearby branch and pointed it out. A block or two later it was a chickadee. He asked what it was like to be attuned to all the life that was around me. I am not sure I know what it would be like not to notice the birds, or the movement of a rabbit in the brush, but I know that I feel more alive when I am aware of these other lives.
Nature and wildness may come in these dribs and drabs in the city, but it is there if we are willing to work to see it.
