Abstract
A method of deterring certain kinds of animals from birdfeeders and birdhouses consists of rotating such avian enclosures at a sufficient speed to deter the undesirable animal. An electronic baffle rotates the avian enclosures at variable speeds for which fast speeds are used to deter animals and slow speeds are used for better viewing of birds. A support suspends the baffle from a tree or mounts the baffle to a pole in the ground. An electronic circuit contained within the baffle senses the animal's presence and controls the speed of a motor that rotates the avian enclosures for a predetermined period of time. Optionally, remote control circuitry may be used in manually deterring animals from the avian enclosures and for better viewing of birds.
