Hello Christina, I can show you what I would do easier than trying to explain. I imported your image into Lightroom 4. I set the white balance -20 which adds more blue making the feathers white. Then I opened the image in Photoshop Elements, under the Image menu I chose Resize and made the canvas larger so I had room to crop differently. I saved the image and opened it in Lighroom and tried different crops. I liked this the best it is a 16x9. Beautiful image, nice detail and colors. Go with the image when post processing. The bird is white, the feathers are white, why make them yellowish. Posted below is what I would do.
