Thanks for the responses, Braves... I was very intrigued when I saw it and I figured it had something to do with an eco-centric reason, but just wasn't sure. Too small to throw a house party, but the "roof" would lend itself to a nice jam.

The bird-watching aspect definitely makes sense for this structure. I wonder if the decline in the bird population this year was due to the hurricanes -- or the vanishing coastline of the ragged boot of Louisiana... most likely both. I've talked with a lot of duck hunters that didn't do too well this year, either; so I know they didn't affect the duck population...

This is a great forum -- amazing to find stuff out. It's greatly appreciated by moi. Now, about those accordions...
