I simply created duplicate layers and worked on each independantly to enhance a small areas like increase the saturation in the eye and beak, then added a touch of colour balance and curve tweak.
reduced the shadow in the bady feather's , selectivley applied gaussian blur and despeckle noise reduction.
Applied Fred Miranda's excellent Action Intellisharpen.
Merged down each successive layer and then cropped the image and applied some light rendering to focus on the Birds Body with emphasis on the crown feathers and eye.
All adjustments were rather small but all together makes quite a difference.
