Squirrels are some of the most conspicuous wild animals in urban and suburban settings.
However, we know surprisingly little about their distributions and population sizes. In some places both species occur, while in other locations only one species is found. We are interested in learning how the distributions and environments of these two species differ. You can help us by reporting your squirrel sightings. In the Chicagoland region, any black squirrel you might see is a variety of the Gray Squirrel.
