A nice find Steven. The mature males seem much less commonplace than females and juveniles (in my experience anyway). I agree with your self-critique about the shadows - a clear, unshaded shot of the the face and the head turned more toward the viewer would have been preferable. While I like the environmental aspect of the image, I think it could be preserved in a tight crop.
Agree on the self critique but good on you persevering to get the image...I like the pose and the space giving the feel the bird is searching...TFS staven
