ABSTRACT:
One or more support rods made of a non-magnetic material have magnets mounted thereon, the magnets being placed with their north-south pole axes perpendicular to the longitudinal axes of the rods and with the north-south axes of magnets of adjacent rods normal to each other. The bottom end of the rod or rod assembly is connected through a flexible sleeve, which may be of rubber, to a support. The sleeve acts as a universal joint permitting freedom of movement of the rod and magnet assembly sideways. The rod swings back and forth sideways in response to the wind and other forces thereby creating a variable magnetic field which tends to repel birds, keeping them from flying into the immediate area and/or nesting in such area.
