a dominator wire comprises a plurality of braided strands forming a continous wire . each separate strand is supplied with an electrical current that is different than the electrical current that is supplied to each of the other strands . a plurality of insulating disks are disposed in spaced relationship a predetermined distance apart along the length of the wire creating discrete wire segments . the spaced distance is selected so that a bird that lands on the wire cannot put both of its feet on the wire between the same two insulating disks . each wire segment has a single exposed metal conductor segment . when the bird alights on the wire , each foot will contact a different metal conductor segment thereby causing a current to flow through the body of the bird causing the bird to be stunned or killed .
