Abstract: In multiple embodiments, the avian impact mitigation system may generally include a pliable mesh that is disposed vertically in front of a window by attaching to a building and hanging down from the attachment points. In some embodiments, the system also includes one or more weighted masses that are attached to a bottom portion of the pliable mesh via one or more deformable members. In many embodiments, the combination of the one or more weighted masses attached to the pliable mesh by the one or more deformable members allows for a gentle and gradual transference of the bird's kinetic energy to the one or more weighted masses by absorbing and dispersing the kinetic energy to decelerate the bird safely and rebound the bird away from the window without making contact with the window.
