How Do I Keep Birds off my Patio Furniture?

Isn't it a pain to have to clean off the "Gifts" left behind by birds everytime you want to sit on your patio furniture?  Well I have found a solution to keep pesky birds off my patio table and even the chairs.  The Solar Bird Repeller sold at Absolute Bird Control.  It uses the sun for power so you do not have to worry about having an outlet on your patio, balcony or lanai.  It "Sweeps" birds away with two "antenna" looking arms that expand to a 5 foot radius.
