What are some ways to protect birds from colliding into large expanses of glass?
According to National Audubon Society’s Director of Bird Conservation, multiple falcon silhouettes placed across the windows will turn birds back. As they fly toward the window, the silhouettes seem to be moving, and as falcons are such effective predators, the birds’ reaction is to avoid that “air space”. Striped window decals that are vertical and close together (about piano wire width and about an inch apart) resemble cages and ultra dense vegetation to birds and they will not try to fly through them. Horizontal wire window decals/shadowing will not be effective, as birds apparently perceive they could fly through that. Large windows, especially those that provide a vista through to the other side of the building, are dangerous for birds because they don’t see the glass and they apparently perceive that they can fly through that “building-forest” to the other side. Plus, birds are making these flight direction decisions very rapidly. I appreciate that you are concerned about this ha
