Sorry, but for me, these show clear signs of over sharpening, especially around the head of the bird; there's a very nice and smooth halo outlining the beak and the head. The tree also shows oversharpening, especially the side opposite of the bird (this seems actually to have gotten worse in the reworked images). And I realise that Jiro and Colin had to work from the small JPG posted, so they had a 'small' handicap
Best solution if you started from RAW: redo from start... If it's a camera JPG, you could try lowering the in-camera sharpening.
