This was sure more difficult than I would have anticipated!
Hey, do you have photoshop now?
So, this was my first try, using a levels adjustment layer, and two curves adjustment layers.
I was still seeing way too much cyan in the white of the breast feathers when looking at the info palette. So opened up one of the curves adjustment layers again, went to individual color channels. I increased the reds to decrease the cyan. I increased the greens to decrease the magenta. I decreased blue to increase yellow. Then on the ends of the diagonal line in the RGB channel of that curves dialog window, I pulled the white end down from 255 to 250 and pulled up the black end from 0 to about 5.
With this as the result.
