Help prevent birds from flying into windows, doors and greenhouses which can cause injury or death. Translucent decals reflect ultraviolet light so they appear like frosted glass to humans but show clearly to birds. Reusable self-adhering decals remove easily. Each pack contains four decals approximately 4" across. Maple leaf or hummingbird design.

Window Alert Decals

I've been looking for something to help prevent birds from crashing into our picture window. So glad to have found them.

Have these decals on my windows. Hanging bird feeders attract many birds. Wild type flying due to some kind of excitement sends them towards the windows also. These decals alert the birds before they crash fully into the window. If anything the alert stops a full crash and the bird will just get stunned briefly. Also important to have enough alerts on the windows.
seem to work
