ABSTRACT:
An easy to assemble mechanical apparatus and methods that create a barrier for deterring birds from landing at or near undesirable perching locations. The barrier is created by a rotating carriage that is propelled in a rotational motion by the wind or an available draft of air. A first embodiment utilizes a rotatable carriage which is an assemblage of individual parts that form one unified rotating body which rotates on antifriction bearing surfaces with horizontally disposed rods extending radially outward therefrom. A second embodiment utilizes a pivot pin which supports the rotating carriage portion and is designed to be placed in a variety of locations by an easy-to-use locknut and groove system. A quick action push-nut, or other means for securing, secures the rods or means for creating a barrier onto the carriage. The carriage rotates about the pivot pin with a multiplicity of rods or a means for creating a barrier extending out to any desired length and at any angular disposition from the carriage.
