WindowAlert decals help prevent bird window strikes! In Butterfly, Hummingbird, and Maple Leaf Designs,
Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is barely visible to humans, but birds see it as a brilliant glow–much like a big stoplight.
To the human eye, the decals appear as frosted or etched glass. Each measures approximately 4 inches across, with four decals per package. Designed to be placed on the outside, at least one decal for every 3’ x 3’ section of glass is recommended. Self-stick, static cling easy application, peels right off with no residue or mess.
Window Alert Decals have received rave reviews and work beautifully to prevent birds from crashing into windows. Available in Butterfly, Maple Leaf, or Hummingbird Designs. 4 decals per package.
If you have a territorial bird such as a Bluebird, Robin or Cardinal, that repeatedly attacks your windows, check out the CardinalAlert.
