The question is a bit ambiguous, so there are two likely meanings: wild bears in nature or the Chicago Bears football team.
Wild bears
In nature, bears live across much of North America, South America, Europe, and Asia, mainly in forests, mountains, tundra, and Arctic sea ice in the case of polar bears. Different species favor different habitats; for example, brown bears are common in northern forests and mountains, while polar bears stay near sea ice to hunt seals.
Chicago Bears team
If the question is about the Chicago Bears NFL team, they are based in Chicago, Illinois, and play home games at Soldier Field. Their divisional and conference place changes week to week during the season, and the latest position is listed on current NFL standings pages.
If you meant something else (like a zoo exhibit or a specific bear you’re tracking), say which bears you mean and where, and that can be narrowed down further.
