AWWI’s Technology Innovation program contracted with H. T. Harvey & Associates to conduct an independent evaluation of the DTBird detection/deterrence system. This report details the findings of a pilot test, which used eagle-like unmanned aerial vehicles (aka, drones) and in situ large raptors to evaluate DTBird’s ability to detect and deter large raptors, particularly golden eagles, and reduce the risk of collisions of these birds with wind turbines.
