Perroquet (named for the member of the parrot family that is the subject of the photos) was an exhibit that ran in late 2008 in Europe. I came across these images on one site, and found the source here.
As much as I am absolutely opposed to any birds being held in captivity (unless there are simply no alternatives), I found these images to be too visually striking to not share.
If you follow the link to where these images came from, you can read about why and how the artist did this, as well as see some more pictures, and 8 short slow-motion videos of the perroquet flying by. The videos are really fascinating if you have any interest in birds, as you get a chance to really see details in how the perroquet flies, thanks to special high-speed cameras that were used.
Though I don't consider myself to be a "bird-watcher" in the classical sense, in truth I could happily sit for hours and do just that - watch birds. So for me, these pictures and videos are the perfect way to really be able to study a bird in flight.
