WindowAlert Bird Saver Window Decal - Hummingbird
WindowAlert is a static-cling 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. The decal can be applied to clean exterior windows with water and a cloth.
Each package includes four decals.
The Hummingbird decals measure approximately 4" across.
How to use:
- Place decals on the outside of the window
- Place ~2 inches apart across the entire surface of the glass
- For best results, replace decals every 4 months. UV coating will fade based on exposure and local elevation.
