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.)

    Seems to work so far; no bird attacks on window.

    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.

  4. Great product! 5 Star Review

    The decals work better than I would have expected. No more birds crashing into the windows. I have found that the time for reapplication can be extended much longer than suggested.

  6. Birds saved! 5 Star Review

    Posted by on 23rd Mar 2018

    This is a miraculous life saving product (for birds). It barely is noticeable on windows but in the 2 weeks I've applied the product, window strikes have disappeared. This is vital in spring as dumb fledges are just leaving the nest. I cannot say how much I love Window Alert. It has saved so many avian lives already. Miracle product.

    Have used the window decals for a few years. Previously, had a few doves hit the windows. No accidents since putting decals on all the windows.

    We have many windows in our house and have had many crashes and dead birds. I found theseV1SHUTDOWN ON 2018-03-31.
    We have been using these window decals for many years. I replace them each spring. There have been several encounters with the windows but very few deaths. They definitely work and do save lives!

  10. Love WindowAlert Decals! 5 Star Review

    Posted by on 12th Mar 2018

    We live on a ridge and have 20 5'x8' glass panels across our backyard which allow us to enjoy the sunrise, sunset and mountain views. We also have multiple hummingbird feeders in our wine court area so there is always increased activity during the morning and late afternoons. WindowAlert decals stops hummingbird strikes on our glass fence and are definitely worth the purchase (10 envelopes - 40 hummingbird decals)! Thank you for helping us save these beautiful "flying jewels"!
