US Patent 10531652 Raptor nest deterrent

A nesting deterrence device for elevated infrastructure is designed to be mounted within a deterrence area on elevated infrastructure, such as cell and data towers, utility poles, sports lighting, and the like, in order to deter raptors (i.e., Osprey) and other birds with relatively long wingspans, greater than 33 inches (84 centimeters), from entering into a deterrence volume immediately above the deterrence area. Birds are deterred from flying through the deterrence volume by a plurality of deterrence rods, spaced and oriented within the deterrence volume, which would interfere with bird flight. Because birds would be prevented from freely flying through the volume, they would be unable to alight and nest in the deterrence area below.
