I used to live in County Club near the golf course and coyotes run into the city and run around the course in the middle of the night. There are quite a few around the UIS campus and Toronto road area, along with tons of deer. Numerous coyotes from chatham to springfield along route 4 and I've even seen a pair recently around the restaurants and hotels on the SE side
It's crazy but they literally are having fun like its their own playground. Hell I've seen Deer multiple times in Washington Park.
I have seen deer, coyote, fox and other creatures many times on all sides of town.
At night, raccoons and possum are as common as sparrows in Springfield.
It seems to have gotten worse over the last couple years.
