Help prevent bird strikes with some adorable Sloth Window Gems.   These guys just want to hang out in their tree branches and watch the world go by, but their presence will break up reflections on the glass and warn birds away in time to avoid window strikes. Window Gems 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 sloth clings ranging in size from 7" tall for the one sitting on the curved tree, to 3.5" for the smaller baby sloth. Handmade in Mount Shasta, California Window Gems are made with a color-less 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.
