Taking the loop walk around Lake Glenview in Gallery Park today, I encountered the Cooper's Hawk Joan and I have often seen over the last few weeks. It was perched, as usual, on top of a tree and as I approached, it took off and swooped directly over my head. It looped around and alighted on another tree further in front of me, where I captured this photo. The bird soon took off again, and I tried to capture its wingspan in the next, very off-center photo.
Later on, I saw the same bird flying south with a mouse or rat in its beak, perhaps heading for its neat somewhere south of Chestnut Ave.
