Thanks to a fellow birder’s discovery, I made my way to a small nature preserve that I never had even heard of called Bell Bowl. This preserve is on the Rockford/Chicago International Airport’s property but is open to the public.
So I made my way down a nondescript road to the preserve. Hanging around the airport with high powered optics always makes me think I may look a bit suspicious. But my skulking went unnoticed.
And I found a pair of Blue Grosbeaks!
