Beautiful bird Tom. Sid right on the too hot whites. I like the soft look of the light and color of the water which says "winter" up north to me. I am debating on recropping suggestions and at first was going to say take more off the top and bottom but the more I look at it the more I like look of the water. I feel you should revisit the crop and work to get something that balances the bird in the image better but maintains the soft look of the water. Nicely done.
I had to take a look at this one because I don't see hot whites at all. (Yes I see all blocks on the calibration strip clearly).
I measured the whites and the highest value I got was 253 in the red channel. The Blue and Green channels were well below. Since the red was significantly higher than the other two channels I lowered it a little with hue and saturation. The change is hardy noticed.
Another option would be channel mixing the Blue and Green with output to Red.
Edit: Oh, and I killed a dust bunny or other oof blob at about 10 O'clock from the head.
