That is a nifty and arresting pose! I like the combination of bird and rocks. The light is harsh and the image quality isn't top-notch, to my eye, but contextually this one is a winner...
Neat situation! I would have cut lunch short too to take advantage of that. With the subject placed where it is in the frame it would have been great for it to look towards our left a bit...as is, it could be placed more centrally or slightly to the left (pointing your camera to the right). Still very nice and unusual...I like it alot!
