One Way to Avoid the Splat of Birds

As long as people have been putting using glass in buildings, birds have been smacking into it.  Sometimes the buildings are too tall, or in a centuries-old flight path, and sometimes the birds are just ... well... bird-brained.

This art school in Chicago put stickers of birds on its windows to maybe give the birds a clue that the wild blue yonder doesn't continue through the glass.  I'm not an expert on birds, but I wonder if the silhouettes chosen are predatory birds, meant to scare other birds away. They kind of look like owls to me.
