@Biftu My office window is a large picture window facing the backyard, it reflects the trees, clouds, and mountains so we had a lot of bird strikes. Some were not fatal but some were, I know what you mean, it broke my heart to remove the birds. I tried the decals, blinds, sheers....finally I found the Audubon bird strike kit, it is strips of frosted tape about 3/4 inch wide that we put on the window, it shows up best in the photo below. I don't find it distracting and the bird strikes have stopped. (FYI-that's an air plant hanging in the window, not a giant spider!)
