Thanks for the best detailed image of this species I have seen yet. My experience with this species is that they are quite skittish. A how you got so close would be appreciated.
A very nice shot of a difficult bird to approach. The original is very nice, perhaps a bit too dark as presented, although I know the day was probably dim. I agree about more NR on the BG.
I took a minute to tweak it just a bit, to help the bird stand out a bit more from the background. I also lowered the brightness of the neck. It was highest value of 253, and now peaks at about 247.
Just some options. Oh yeah, I also reduced the brightness of the lower part of the branch, which was bright enough to draw my eye.
