In his movie The Birds, Alfred Hitchcock showed feathered thugs terrorizing a small town. If birds have zeroed in on your home too, and are messing up your decorative wood fence by sitting on top and doing what birds do, here's a simple solution. Bird droppings mar the decorative beauty of a redwood or cedar fence. The answer? Keep them from perching by installing rows of small screw eyes on each outside edge and in the center all along the top fence rail about every five feet or so apart. Then string three rows of clear fishing line through them from end to end again with one on each outside edge and one running down the center. The result? A poor landing spot for birds, and from a distance you won't even see the difference.
