Common Goldeneye - Wisconsin Birding - M.C. Kinney Photography - Appleton WI

Yesterday while waiting for an Immature Bald Eagle to take to flight, I was being amused by some male Common Goldeneyes that were amusing themselves by riding the rapids on the Fox River. I'd like to think they were fishing, but they never dove under water to actually fish. Instead they would ride the white water north (trivia question: what other well known river runs south to north?) for about 100 feet then fly back to the start of it and repeat. This went on for the entire time I was watching the eagles, which was over an hour, and still going on when I left. Here are a couple of images of them in flight returning to the start of the fun.
