ABSTRACT:
A vineyard has conductive trellis wires which extend between poles to provide support for the grape vines. At least some of the trellis wires are grounded. A number of identical bird repelling devices are widely spaced throughout the vineyard. Each has a length much shorter than the distance between adjacent vineyard poles, the length being sufficient to allow a bird to land. The bird repelling devices have a circumference less than approximately one and one-half inch to allow the feet of a bird landing thereon to cover most of its circumference. Each bird repelling device is composed of an elongate insulating member and an electrically conductive rod secured to it. The rod is substantially as long as the elongate insulating member. A high voltage is applied to each electrically conductive rod. Each of the elongate insulating members is secured to a portion of the trellis wires parallel to the trellis wires. A bird landing on a bird repelling device completes a circuit between the trellis wire and the electrically conductive rod carried by that bird repelling device. This shocks the bird without substantially harming it so that the bird flies away. Mounting fixtures mounted on vineyard poles at the ends of rows readily accept, hold, and automatically make electrical contact with modified bird repelling devices.
