It looks to be a large crop due to the lack of finer detail and over sharpened. There's a distinct halo all round the bird, particularly noticeable above and around the head and lower body. A tad central too but the exposure look fine and the sky has held some colour.
The white 'halo' seen particularly around the head and neck has disappeared on this latest version you have posted.
As an aside you should never worry that you would offend me, both you and Brash made an observation, it was something I had not seen which gave me the opportunity to correct the issue.
