I believe that it is a device for listening to, and recording, bird songs.

Hi, On the Pt.Pelee posts, I wrote that much more important than fancy long glass for a bird photographer is patience. Without it, and preparation, you are just a snapshooter.
So, to be more constructive, I found this gallery of birding blinds, to show you and inspire you. Preparation, literature and knowledge of bird etology is most important if you want your bird photograps to show something more than just the damn little critter curiously looking at you, even though you have the best 1200/5.6 supertelephoto... And a lot of bird pictures over the web show only this. Surprised birds looking at the photographer, nothing else. That's the same as if you walked along the street with a 300/2.8 lens and all you photographed were curious and angry faces of the other citisens.

Look at the first one, it's actually quite funny... birding blind with a satellite dish :)
Good light, Frantisek Vlcek
