Hello Pinaki, nice image of a beautiful bird. I wish I had it in Florida to photograph. You mentioned the background being distracting, I took the liberty to edit your image to show a way you can overcome that. Here is what I did. I cropped the bird a little tighter with a square crop which eliminates some of the background. Then using Adobe's Lightroom 5 post processing software I used the Radial Filter with an elipse around the bird to darken the background outside of the elipse by 1 stop of exposure. Next I lowered the Clarity on the oustside of the elipse by -50 and moved the Shapening slilder to -60 which added to the blur of the background outside of the elipse. I am posting the image so you can see what I did, if you would rather I didn't I will remove it.
