I didn't do much to your good image, just adjusted shadows, contrasts and saturation.
I hope you don't mind me playing around with your image. Let me know if you like it.
Thanks again for sharing.
I cloned the iron bars and some other branches that I found intrusive.
I blurred the BG a bit and sharpened the bird.
Removed noise and framed to make the bird stand out.
Hope you like it and do not mind!
