A squirrel named Shirley moves in on the bird feeder and a physicist dreams up new ways to foil her. A rotating shield initially blocks her, but with each physicist’s innovatrion, Shirley uses her squirrel brain amd powerful ability to climb, balance and juimp to solve the problem and munch on the bird seeds. Along the way are some spectacular fails and amazing successes for this wild animal. These Fox Squirrel imported from the East Coast are admirable and irritating adveraries for sure.
