If you are squeamish, be warned, this is a bit graphic.
There was a lot of wind so there is a bit of jitter, something I hope to fix if I get the proper software. It was taken with a 500mm lens on a Canon 5d2, and demonstrates how much even a small amount of movement is multiplied with a large telephoto lens.
Update:I have done a motion stabilized version which rids it of jitters. See here
