I am looking on a crappy work monitor so keep this in mind.
Wonderful color, detail. Appears noise free.
Nothing needs to be done, in my opinion.
Alternatively you might consider a tighter crop, eliminating the broken branches upper left. You lose some of the environmental aspect but perhaps some distraction and allow a greater feast on the bird.
Hope to see more. This is fine work.
So, finally, since you seem to more than know what you are doing, what are your questions for Critique?
