Abstract: A bird deterrent has a base and at least one branched spike extending from the base. The branching can occur anywhere along the spike, and a single branch point can give rise to multiple branches. Spikes can have multiple branches. The various branches can be of any suitable length(s), and can be oriented in any suitable direction(s).

Abstract: An adjustable bird slope has a face that can be extended or contracted so that the bird slope can effectively fit almost any perching area.

Abstract: A bird deterring device has a base and a stem, wherein a plurality of spikes are coupled to the stem and/or base, and wherein the distal ends of the spikes have an anti-condensation drip element to avoid or reduce drip marks produced by previously known devices.

Abstract: 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.

Abstract: A bird deterrent device generally has a base, a plurality of mutually parallel directing channels, and a plurality of spikes extending from the base. The channels are preferably disposed in rows so they are not only mutually parallel, but also coplanar. The spikes are inserted into the channels, and then at least some of them are bent out so that the top ends of at least some of the various spikes are oriented at least 5 degrees out of parallel with respect to each other. The resulting spikes are therefore “fanned out,” and tend to prevent birds from landing in the immediate vicinity of the device. The bottom of the spikes are fixed into the base in some manner, preferably using a second bend and then crushing portions of the base adjacent to the bent sections to maintain the spike in places.

Abstract: A bracket insulator is designed to provide support for wires carrying electrical current to repel birds. Each bracket is configured for receiving a wire in a slotted hole. There are five such slotted holes in the preferred embodiment. Thus the bracket provides for holding up to five parallel wires in spaced relation. The spacing is selected to provide a high likelihood of shocking birds that land on the wires. The brackets provide additional slots for alternative wire mounting as well as a variety of holes for still other wire supporting paths. Bracket mounting holes are also provided.

Abstract: A preventative device against nuisance from birds comprised of a base to which spikes are fitted to extend opposite surfaces of a structure to be protected in order to discourage birds from landing on those surfaces. The base is provided with canals and each spike has a knurled end. The maximum cross section of the knurls is slightly larger than the cross section of the canals. The spikes are force fit into the canals so as to be held firmly therein. In an illustrated embodiment, the base of the device is made from ultraviolet light-protected polycarbonate plastic in a variety of colors to match the area covered.

Abstract: A bird repellent apparatus which is specifically designed for installation on telephone and electrical wires and the like or other extremely narrow, elongated surfaces to which it would be difficult, if not impossible to install any prior art bird repellent apparatus. More specifically, a channel member is configured for receiving a large plurality of top members in a continuous serial array, wherein preferably the prongs of a plurality of top members all lie in the same or substantially the same plane. In the preferred embodiment disclosed herein, the channel member is affixed either by adhesive materials or fastening elements to a cable clamp which, in one exemplary embodiment, comprises a pair of matching C-shaped members having flanges, at least one of which can be selectively fastened by a fastener, such as a bolt or a rivet. The clamp is adapted to encircle and compressively engage a cable, such as a telephone wire or electrical wire.

Abstract: A bird repellent apparatus having a base member and a plurality of top members, each of which holds a plurality of prongs. The base member, by means of a plurality of tabs having holes for receiving screws or other fasteners, can be affixed to virtually any desired surface with little or no risk of injury to the installer. The top member comprises a prong holder, each having a plurality of prongs with sharp tips presenting an impossible barrier to birds that would otherwise land or perch on the surface to which the present invention is affixed. The top members are adapted to be press fit onto the base member after the base member has been installed on the underlying surface. In an alternative embodiment, the base member is an extruded plastic structure that provides countersunk holes to secure the base member to the underlying surface without the need for tabs.
