Making window glass visible – but only to birds

9 octubre 2014

Ultraviolet patterns can make window glass visible to birds, thus preventing fatal collisions. However, it has now been shown that such windows are not likely to work for all species, but only for birds like small passerines, gulls and parrots, who have a special type of color vision. For birds of prey, geese, pigeons and crows, these patterns are likely to be too difficult to detect.
