This idea for birdhouses is pretty clever. And I can't help put think that being suspended on wires is also a great way to avoid predators such as snakes! Unfortunately, like most art installations, it has now been dismantled. But there is nothing stopping you from creating your own! Read about it and see more pictures of this project over at the iGreenSpot site. LINK
Or visit the artist's blog directly and track the progress of the installation and the birds who called it home for a season in posts from the summer of 2011. LINK
