Cardinal Alert is a decorative adhesive strip, 6 inches wide, that is placed at the bottom of a window which is being ‘attacked’ by Cardinals or Bluebirds.  These birds, especially males, see their reflection in your window and repeatedly attack the reflection, thinking they are driving off a competitor.

The Cardinal Alert strip blocks the reflecting surface along the windowsill, stopping the reflection and the attacks.

Each strip is four feet long and can be cut to fit.  Multiple strips may be needed for multiple windows.

A static cling window decal in the traditional hawk shape.  Helps reduce or prevent windowstrikes by birds.  Two per package.

WindowAlert decals help prevent wild birds from accidently striking windows.

Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow – much like a stoplight.  To the human eye, the decals appear as frosted or etched glass.

Decals are static cling, very durable and can be removed and replaced while cleaning windows.  They should be installed on the outside of a clean window.  A package of four will protect one large window or patio door.

Choose from four patterns – Maple Leaf, Butterfly, Hummingbird, Snow Flake.
