This is the Northern Flicker, a fairly common, robin-sized bird in Illinois. However, I waited until last year, as a 63 year old, to see one. Just never saw one before, because I probably never looked. I like this guy. Pajamas with spots on the bottom. Stripes on the wings. Squares underneath in the back. A red spot. Brown coloring. Some grey. There is a lot going on here. Fun bird.
