An ordinary nature walk leads to an extraordinary discovery in the western suburbs.

Jerry Zamirowski of Glen Ellyn found a rare blue bullfrog at the Hidden Lake Forest Preserve in Downers Grove.

ABC7's news partner, the Daily Herald, shared a photo of the bullfrog with us.

An ecologist says the rare color is the result of a genetic mutation.

More about the frog will appear in Friday's Daily Herald.
