Near Lake Michigan are found numerous gulls, waiting for a free handout from people walking the beach. Deer are ubiquitous, as well as squirrels. Occasionally, a deer will wander out of a forest preserve or wooded area and make its way into the City of Chicago. In wooded areas raccoons and rabbits are more common. Less common, but still frequently spotted are a variety of non-poisonous snakes such as the garter and the prairie king.
Poisonous species are almost non-existent in northeastern Illinois.
Frogs of all types haunt wetlands and lakes and can be heard most summer nights, while turtles may be spotted swimming or sunning during day hours. Over 750 miles of established trails exist, with hundreds more under construction or planned. Most trails are multi-use, so practice trail courtesy. On trails where horses are allowed, horses have the right of way. Bicyclists should also yield to all slower-moving traffic such as walkers and joggers.
