Prevent birds from striking windows!
Complete Kit includes 32 WindowAlert Decals and UV Liquid Marker!
Birding enthusiasts share a similar problem: wild birds fly from backyard trees and feeders into home windows where they are injured or die. Wild birds also collide with office windows. In North America alone, tens of millions of wild birds die in this manner each year.
Now you can help reduce this loss of life!
Solution: WindowAlert is a high-tech decal that may be applied to home and office windows. The decal contains a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows like a stoplight for birds.
WindowAlert decals are four inches wide and are static-cling. They easily attach and peel off window glass. Made in the USA!
4" Decals available in seven attractive designs - Maple Leaf, Butterfly, Hummingbird, Snowflake, Classic Square, Modern Square, Leaf Medley, Aspen Leaf, and Pinecone Medley.
WindowAlert Decal 32-Pack comes in four envelopes (same design). All designs (except Leaf Medley and Aspen Leaf) have 4 decals per envelope, 32 decals total. Leaf Medley has 5 decals per envelope, 40 decals total, Aspen Leaf has 8 decals per envelope, 64 decals total.
Want Mixed Decal Designs? Select your primary decal design choice when you checkout. If you want two different decal designs you may select an optional Decal Design #2 in the shopping cart.

UV Flashlight Decal and UV Liquid Tester
Make sure your decals and UV Liquid still glow brilliantly for wild birds. WindowAlert decals and WindowAlert UV liquid have a coating that brilliantly reflects ultraviolet sunlight. Like any product, man-made or natural, our UV coating will degrade when exposed to the elements. The rate at which this coating degrades is a function of exposure to sunlight, inclement weather, and elevation. Depending upon these variables, decals should be replaced every 6 to 9 months. This 365 nanometer LED UV black light flashlight can be used to test the quality, or fading of WindowAlert products. For best results, compare your OLD decals to a NEW decal--at night. You will see, it’s fun to do! Four AAA batteries not included.
