Hummingbird Decal Envelope - 4 decal pack

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.)

  1. Great product! 5 Star Review

    Posted by on 11th Apr 2018

    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.

    I have not had a bird strike since I started using this product along with the UV Liquid!! It’s a terrific product to save the lives of birds!

  3. 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.

    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!

  7. 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"!

  8. These stickers really work !!! 5 Star Review

    Posted by on 22nd Feb 2018

    I purchased these stickers but I was not sure if they would work. The birds kept flying into my sliding door. Once I put them on no more birds. I’m so happy about this. I love feeding them. Problem solved. I also purchased another set. Thank you

  9. Works as Advertised 5 Star Review

    Posted by on 10th Jan 2018

    We used to experience fairly frequent bird strikes to our windows. Since using the WindowAlert decals, we have had no bird strikes. The decals are nice looking -- we use the hummingbird decals. They do look like etched or frosted glass when viewed from inside the house. They are not obtrusive to the view and they do the job as advertised.

  10. Not impressed (Feeders may be too close to windows!) 3 Star Review

    Posted by on 3rd Oct 2017

    I have a very small window that is close to where I feed my birds. i put the decals on the window. I am still getting bird hits. I am disappointed because I was really counting on these working to solve my problem. (Feeders should be within one foot or more than 30 feet from windows. Many customers put feeders at 10-15 feet not realizing they are contributing to bird collisions.)
