Includes 4 decals, various modern square designs. 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 a recent article in a supplement to Living Bird Magazine
, Marie Ann Johnson of the Cornell Lab reports that an estimated 100 million birds are killed and many more injured by flying into windows in North America every year.
SOLUTION: WindowAlert is a 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 sold in over 600 bird hobbyist stores across the country. Enthusiasts enjoy the unobtrusive appearance of our decals and their scientifically proven performance. To the human eye, the decals appear as frosted or etched glass. The decals measure approximately 4" across, and are designed to be placed on the outside of a window. As a rough guide, we recommend one decal for every 3’ x 3’ section of glass.
