I MHO... Actually, nothing goes wrong with the exposure .
I would say that Duck is sharp enough, but Heron is a little out of focus.
How far is the Heron from your lens? Since 50% crop i guess that it should be about 20-30 meters.
How did you set the "Selecting the Focusing Area".?
Shot far from the bird with bright backgroung, spot metering + sets the focusing area to the Center of the viewfinder (single point) will give a better result.
BTW, 300mm is too short, 500mm is much better and a large size of bird in the viewfinder is also better for focusing at the brid.
.....ivoire, thanks for your comment on my picture.

A sample image from Sigma50-500EX with hand held.
I am sure that at 300F4+1.4x, the MTF as IQ would be reduced significantly.
