Avian streamer deterrent for electric power line support structures

An avian streamer deterrent comprising:

• a hollow member comprising an inner wall defining a cavity configured to receive a wire coupled to an electric power line support structure and disposed above at least one insulator of a conducting wire, the hollow member further comprising a helical configuration such that a first end of the hollow member curves towards the cavity and a second end of the hollow member curves towards an outer wall of the first end;
• and
• two or more fins extending outward from and longitudinally across the hollow member.

An avian streamer deterrent system comprising:

• an electric power line support structure coupled to a plurality of conducting wires, wherein each conducting wire of the plurality of conducting wires is coupled to an insulator;
• and
• at least one avian streamer deterrent disposed above the insulator of at least one of the conducting wires of the plurality of conducting wires and further disposed on a wire situated above the plurality of conducting wires, the at least one avian stream deterrent comprising a hollow member that includes a helical configuration configured to receive the wire.
