A great shot of a beautiful species. Very good exposure, nice light, extremely shallow DOF keeps focus on the bird's eye. Some of the lighter BG areas in top left and bottom left I'd tone down a bit if it were mine. Wish for some eye contact, but still a spectacular shot!
Oh man, if only the bird had looked your way instead of away!! I normally don't mind shallow DOF when the bird is focussed properly on the eye (as it is here), but I think upping the ISO and stopping down would have been good for a bit of additional DOF on the perch (which is pretty cool BTW). Thanks for sharing this neat little species!!
