Some highly territorial birds vigorously defend their territories, and will even attack their own reflections in windows. When a bird attacks, it puts its own health and energy at risk. This activity can compromise the success of its nest and its brood.

CardinalAlert is a window decal designed to be placed along the bottom edge of problem windows, eliminating reflections from birds that mount their attack from a windowsill perch. * CardinalAlert brings peace of mind: The bird is safe from itself, and your home and office windows are no longer under attack. Window Alert decals may be used only on an exterior glass surface - free of any overlay, tinting, film, or coating. Clean glass first with water. Avoid use of chemicals such as ammonia or window cleaners. Decals are best applied when glass is warm (ideally greater than 50 degrees). If applied during winter months, clean glass with warm water prior to application. Place decals alone or in groups every few feet on the outside of the window. Position out of reach of infants and small children. Restore static cling by rinsing in lukewarm water. UV coating may fade based on exposure and local elevation. Replace decals every 9 to 12 months.
