Anti-Collision Window Alert Bird Stickers Glass Door Protection Save Birds Window Decals - Set of 15 Silhouettes

We have a sunburst window in our living room. The birds were constantly slamming into it. It had become a nuisance. I ordered these stickers and placed them. They worked like a dream, until they didn’t. I believe the birds figured it out and began slamming and pecking at the window again.
