Abstract: A device for installation on the crossbar of an electrical power pole to prevent birds from landing on the crossbar and accidentally electrocuting themselves by touching adjacent power lines supported by the crossbar. The device comprises a generally "U"-shaped bracket member adapted to fit around the girth of the crossbar, with a planar framework attached to the upper leg of the bracket so as to extend upwardly from the crossbar when the bracket is fitted around the crossbar. The free end of the upper leg of the bracket has lip extending outwardly and upwardly therefrom, and an elongate bar having one end bent back over itself to form a hook is positioned with hook fitting over the lip. The elongate bar closes the crossbar within the bracket and means are provided for securely attaching the lower end of the elongate bar to a lug or ear extending outwardly and downwardly from the lower leg of the bracket member.
