I feel I must make a comment - but all the relevant points seem to have been already covered above!
It is certainly a lovely quiet, well composed image of a beautiful bird.
Splendid image; all of the aspects of a good shot are pressent. I've noticed that the bird does not have the rufous colouring in the top of the head; nor the dark patch on the occipital region of the head. Is this common? Great shot.
