To birds, trees and sky reflected in glass appear to be habitat. They fly into windows at high speeds, and the loss of life is staggering. Unlike humans, most birds can see UV light. It therefore stands to reason that applying UV-reflecting coatings or patterns on windows and glass buildings can be particularly advantageous to prevent bird strikes. Tuning the UV reflectance properties of window glass (or any other surface for that matter) could result in higher UV reflectance that could be noticed by birds and potentially reduce bird-strike incidences, particularly in high-rise buildings and airplanes.
