Save birds from window collisions with these fun Cardinal Window Gems.  We have made a small flock of them for you to arrange however you like on your windows.   They break up reflections on the glass and warn birds away in time to avoid window strikes. The decals stick to the glass purely with static cling, not adhesives, so they are movable, reusable and never fade. Comes in a package of 7 different cardinals,  ranging in size from about 4.5" to 7" long.    Some are perched on branches, some are flying, but all of them are sassy and adorable. Handmade in Mount Shasta, California Window Gems are made with a colorless translucent prismatic vinyl which captures sunlight and turns it into sparkly rainbows. They are stunning, constantly changing, and perhaps a teeny bit magical. Any bright light source makes the gems glow with rainbows, even moonlight.
