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.
