It was at this point that I realized what was going on and pulled my camera back to include more of the area so the squirrel could be seen. It had climbed the fence and seemed to be advancing on the hawk. I thought for sure the squirrel was a goner and lacking in intelligence. Time stamp still says 4:51.
