This raccoon walked in circles for over an hour while I was at this location. Its circle wasn't always perfect but it never strayed further than ~10 yards from the same location. Clearly not grooming itself, apparently no awareness of myself or the nearby ducks, and would occasionally absentmindedly step off the ice and into the water. It stepped off the ice briefly when I was observing it closer, but when I was further away I observed it swimming a bit before returning to shore. Likely won't be alive much longer.
