Opened the nef in ACR
'Shift+left mouse click' to do a white balance dropper on snow, this changed the As Shot WB; 5200 and -9, to 5700 and -19.
Auto, then make other adjustments which resulted in these:

Open Image (in PSE6)
Capture Sharpen with USM: 200%, 0.3r, 2th
Levels: set grey point at 1.7 (to lift the bird)
Convert to 8 bit depth (have to)
Make a Layer, work on that from here on in (allows one to switch it off to compare back to original)
At this point I made a selection of all the snowy areas including all the background stuff, leaving just the bird and the feeder out, then I inverted it.
Thus most of the following was applied to only the bird and feeder.
Local Contrast Enhance: USM 35%, 160r, 0th
