Hummingbird Decal Envelope - 4 decal pack

Product Description

WindowAlert decals help prevent wild birds from accidently striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight.

To the human eye, the decals appear as frosted or etched glass. The Hummingbird decals measure approximately 4" across. WindowAlert decals are designed to be placed on the OUTSIDE of a window. As a rough guide, we recommend one decal for every 3' x 3' section of glass. Reapply decals every 6-9 months.

CONTENTS: 4 Decals per Envelope. TYPE: Static cling.

(If a bird repeatedly attacks your windows, please consider our Stop Bird Attack product.)

Will always use!

The decals are pretty, they work and they are long lasting. I have suggested my friends to use them many times.
If it saves one its worth it!

Found these clings at a great price and with very reasonable shipping. Wanted to try something to stop the crashes into our doors. We have 4 sets of French doors on our deck and it breaks my heart to have one of my feeder birds lose its life by hitting the glass. Hope theses clings work. If they save one little bird, they're worth it.
They work!

These decals when used in conjunction with the UV liquid really help reduce bird collisions

I’ve used these for years. They look nice, they are transparent. They are easily removed and they don’t look junky. Most importantly, the birds have stopped crashing into my windows. I replace all of them every six months.
Happy they helped

Safe windows

Decals are easy to apply and remove. They look good and do not obstruct vision through the window very much.
Saved the birds

Birds were hitting our back windows 2 - 4 times a week, some didn't make it. After adhering the window alert stickers 3 weeks ago, we haven't had 1 bird hit the window and looks nice from inside the house. Fantastic Product!
It Works!

I was using Mylar paper and although that worked, it didn't look very nice. These decals look beautiful and work. I first discovered them at Best Friends Animal Sanctuary, bought some there and just had to have more so ordered more online.

Seems to work so far; no bird attacks on window.
NO MORE WINDOW COLLISIONS

The stickers apply easily, no collisions so far, and an extra added benefit is the lovely unanticipated violet hue that projects thru the hummingbird figures when the sun shines-in San Diego daily sunshine seems eternal.
