Agree with the comment about a narrower aperture...moving to the left- not sure if it was possible, but with all that I heard about how used these birds are to humans (in Ranthambore), may be it was worth trying.

Now dada, this image was made an year ago...you know, I know- how much you evolved as a photographer in this time....where are the flamingoes and storks and herons? Look forward to some recent work from you
