Decals do help stop birds from colliding with windows - especially if they are ultraviolet. WindowAlert has a good selection of decals and prompt delivery. Put more on than you think you need and replace them yearly to help save beautiful birds.
My order was shipped quickly and the website was very easy to use.
Great product and great service. I would always use this site again.
Product is as described. Easy to apply. Arrived right on time.
We love our hummingbird stickers. Most of all we love that they help us protect our birds. Thank you for your service.
I have used these before, they do work. Quick delivery for me here in Virginia. thanks.. good product.
Effective product & reasonable price with quick delivery. I love being able to buy the bundle of “blemished” decals - they have minor markings or mis-shapes but work just as well as the “perfect” ones!
These are great! Was not sure what to expect but the birds hitting the glass doors and occasionally dying was breaking my heart 3 days after the easy application and no bird strikes. None. There used to be at least a dozen or more per day.
Window Alerts are a useful product in our store -Wild Birds Unlimited. The decals are visually attractive and do the job! Plus, we love that they are made locally in Oregon! ( we are located near Seattle, WA). Their customer service is excellent. Thorough and expedient! Our customers have reported to us that the decals work well to help reduce birds hitting windows. 👍
I have been using the decals for several years. They work great. Highly recommend.
The decals are unobtrusive and look great. It's so important to give birds a chance!
These stickers seem to make a difference and are barely visible from inside or outside. Love the design choice!
These decals save the lives of migrating birds who are unfamiliar with the areas they are passing through. Without them, we lose 4-5 songbirds per year. With them, none. Definitely worth the price. And they last!
Your product is quite expensive. I had to use 4 cans to get coverage on two side by side windows and the coverage is still spotty. It will wash off with a rain.
The window stickers do their job very well, warding off birds on collision paths.
WindowAlert works! We had birds flying into our windows and now we don’t!
Quick and efficient shipping. Our orders always arrive fast and in great condition.
