I would agree with =ppigeon on the technical aspect, although I think the overall composition is good. I think if the aperture had been much greater, the twigs in the background would have created too much of a distraction. It's a beautiful bird though, and a nice angle. We don't get them in the UK, so it's nice to see a different variety.
i have to let y ou know, i blurred the background of the bird to make it pop more and to lose the background. in so doing i blurred the top of this birds head by mistake. believe me it is in focus, just got blurred on top of its head.
