ABSTRACT:
A bird spook for frightening unwanted birds and other pests from a designated area such as a building, crop field, etc. The spook comprises a thin disc-like plate having at least one light reflecting surface suspended from a supporting arm by a swivel connection. The supporting arm may be attached to any surface of a building by an adjustable support bracket which enables the arm to assume any angle with respect to the building surface to insure freedom of movement of the reflecting plate. Alternatively, the supporting arm is made vertically adjustable for varying the height of the reflecting plate above the ground in crop field protecting installations. Air movements cause the plate to oscillate producing random light reflections annoying to birds and other pests.
