Abstract: A bird deterring device for protection of a reservoir or other body of water is disclosed. The deterring device provides an array of wires stretched across the reservoir, wherein adjacent wires are oriented in a parallel manner and are spaced apart by approximately 12 feet. Each wire is supported at a first end by an anchor rod driven into the ground of the shoreline defining the reservoir or body of water. Each wire is supported at a second end by an adjustment rod carrying a wire tightening mechanism which allows the wire to be tightened until taut. The wires reduce or eliminate use of the body of water by water birds by providing both visual and auditory deterrents. Wind, moving about the wires, creates a high-pitched whine that tends to annoy and repel birds. Additionally, birds tend to reject making a water landing due to the location of the wires, preferring instead to divert to other bodies of water.
