Blacks are noisy (trying to recover some detail), lack of detail (large crop), I like the pose.
I have been trying to get a decent shot from this species for couple years now, but this guys have not given me many opportunities. Maybe this summer I will get a decent picture.

Super pose; you even got an open beak. Overall the image quality suffers from the heavy crop. Since you're already high-key, I'd push the exposure even further to the right, perhaps 2/3 or even a full stop.
