| Birds navigate by using the earth's magnetic field-disrupt that field and they completely lose their sense of direction. Birdie Barrier's magnetic system disturbs the magnetic field for a 20' radius-without batteries, electricity or costly operation! Holographic surface provides added deterrence. Completely safe for birds, people, pets, and the environment. Attached hook for hanging. 4 1/2" x 6". 2 or more sets $14.99 each
