Abstract
Abstract An electrical device for mass exterminating of objectable pest birds, such as starlings or the like; the device including an overhead cable supported between posts, the cable carrying a plurality of spaced-apart copper electrodes along its outer side, so that, when a horde of pest birds try to land upon the wire by their toes straddling it, they close an electric circuit between the electrodes, which are connected to a power source, so that the birds are thus electrocuted.
