During the tour we heard lots of birds chirping. At least we thought they were birds. That was until someone else told us that sweet chirping sound was actually being made by tree frogs!!! What?… we urban Chicagoans don’t know much about tree frogs?!!!
Intrigued… we set out on finding the source of the sound.
Can you spot it hiding in Bob Briscoe’s wood pile?
