Save birds from window collisions with a flock of Mini Macaws Window Gems on your windows!  These gorgeous tropical bird clings help actual birds see your windows by breaking up reflections on the glass. Mini Macaws come in a pack of 7 Gems.   They range in size from  3.5" - 5" across.  Our decals stick to the window purely with static cling, not adhesives, so they are movable, reusable and never fade. 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.
