摘要:
A squirrel deterrent support for a bird feeder includes an elongated rigid substantially straight pole of at least five feet in length. A hook at the upper end supports a bird feeder and a bracket at the lower end supports the pole on a fixed surface so that it extends upwardly and outwardly at an angle of about 60°. A plurality of elongated tubes surround the pole and include bearings at each end so as to rotate around the pole. Each tube carries a barrier in the form of fan blades that extend radially outwardly and rotate with the tube. A circular baffle in the form of an inverted bowl is carried by the pole above the barriers.
