It is a person, but looking closely at the original, he is sitting down next to a blue cooler. This zoom on the first image gives a better idea of the size relative to people. According to wikipedia it is 160 ft tall, 1180 ft long at the top, and descends about an inch from one end to the other. It was built to bring water to Nimes, and it only descends 56 ft over the course of its 31 mile length. Truly impressive.

I had a huge hoya a few years ago.....too huge! It hung from a beam in an alcove with incredible SW, S, SE exposures from three windows. It would be covered with nearly a hundred blooms for several months. OMG, I grew to hate that chocolatey smell! On a day that I was showing my bonsai collection in order to sell them, someone begged me to sell the hoya, too! Yay!

This is not quite in focus as I hand held the camera while zooming. It is just a great looking duck though.

Thanks skibby, but I'm very worried about them. They're right outside our screened back porch so I can look at them any time without disturbing them or Mom, but the nest is less than 4 feet high. Not a great location for a bird nest in my opinion.
