Shot at Falcon SP TX.
1D MK4, 300mm2.8, 1.4TC.
f5.6, 1/5000, iso400,
Cropped, slight exposure, fill light and contrast adjustment, some sharpening and noise reduction in ACR, removed small oof branch lower right corner.
Excellent image! +1 on Bob's comments, especially his suggestion about the blacks. On my monitor (MacBook Pro, not calibrated) the entire bird seems too dark. I DL'ed the image and took it into PS and used the S&H adjustment to bring up the shadows and it brought out a lot of detail in the body.
Thanks Todd, John and Bob for your comments.
On my calibrated 27" iMac I can see feather detail in the dark area of the bird and the whites on the neck are bright without losing detail. In real life the body of a Caracara is a dark brown, almost black. As I see it on my monitor, the image of the bird as originally posted looks quite natural to me.
I have reprocessed the image as suggested.
Do you like this version better?
