Protect birds from window collisions with these adorable Saw-Whet Owl Window Gems.  They break up reflections on the glass and warn birds away in time to avoid window strikes.   And they are lovely!  One owl sits on a leafy branch under a crescent moon and then there are 9 oak leaves for you to arrange however you please.    The decals stick to the window purely with static cling, not adhesives, so they are movable, reusable and never fade. Comes in a package of 11 individual clings.  1 owl on a branch,  1 moon, and 9 leaves .  The owl is 7.5" tall, and the leaves range in size from 3.5" - 5" long. 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.
