A great looking bird, sharp, perfect exposure, and really cool water. For my taste, the bird is too far forward in the frame--just a bit. I'd rather have the bird a bit farther back in the frame with a bit more room in front.... What to do? There are several AF Area Modes with the 7D that would likely have helped you to create a slightly better image out of the camera. (Adding canvas with water like this is a pain.)
My 7D Guide covers all of the preferred AF Area Modes and the plusses and minuses of each :)

Probably twice as much room in front as is at present would have made this top notch. Not that it isn't as is presented anyway. Nice work to get so close to this species. Love the water BG and the droplets at the base of its neck. Well done. :)
