Has anyone ever tried these stickers to avoid bird strikes ?

Pro or Con , need some input.

No, but thank you for the link I am going to order some. my desk sits at two picture windows and they are hit by birds all of the time. I will let you know if they work.

I have used the Hawk Decals to scare the birds because they're hawks I printed a patten and had my print shop cut them out of black vinal that just stuck to the glass with water. up here you buy the vinal by the ft. and thay will cut as many as they can.
