Window Alert Decals – Hawks

Many songbirds are killed by flying into windows. They see the reflection of the outdoors and smash into the window. These decals static cling to the window. You barely see anything. The birds see a brilliant blue ultraviolet glow which alerts them that something is there. You get two hawks in a package. They must be put on the outside of the window to work. No, the fact these are hawk decals will not scare the birds.
