A bird deterrent comprises a flap that is mechanically coupled to a wire or other support structure using a connector having a ratcheted or other locking or biasing gripping mechanism. The flap can be any suitable size, shape, and configuration, provided it has a sufficiently large wind-catching surface, and is large enough to deter birds. Movement of the flap in the wind can be advantageously facilitated with a swivel. When used on power lines, both the flap and the connector should be made from an electrically insulating material. In preferred embodiments the ratcheted gripping mechanism permits only tightening and not loosening, and the surfaces that directly attach to the wire or other structure are concave and/or ribbed.
