WindowAlert Aspen Leaf Anti-Collision Decal – UV-Reflective Window Decal to Protect Wild Birds from Glass Collisions

WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal features a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, and to the human eye the decal appears as if it were frosted or etched glass. For birds – they see a brilliant glow, much like a stoplight – which deters them from colliding with your sliding door or window. WindowAlert decals come in several designs: Butterfly, Hummingbird, Fall Medley, Snowflake, Maple Leaf, Modern Squares, Classic Squares, and Hawk. Product Specs:The static-cling Butterfly decals measure approximately 4″ across, and are designed to be placed on the EXTERIOR side of the window or glass sliding door. As a guide, the recommendation is one decal every 3’x3′ section of glass. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight. What’s in the Box?Four Butterfly decals per envelope.
