This may look like an ordinary fence, but it's not ...
It surrounds the section of Vogelei Park (Hoffman Estates, Illinois) that is used by the Northern Illinois Raptor Center ...
to house and display their birds ...
Each little house (Mew) houses one raptor, except one that is divided to house to smaller raptors. They are built to specifications issued by US Fish and Wildlife.
The front of each house is a weathering yard where the birds can get fresh air and be more easily seen by the public.
So you see, this is a very important fence because it protects our birds. Some fences are just very special :)
