I only shoot with the TC on, so your rec of f7.1 is incorrect, the lowest f-stop possible is F8.. and as to your other suggestions, thanks for your input.

We can see this now in the EXIF information. Without the TC the lowest possible aperture setting is f/5.6. It's the TC that makes it f/8.
Your second (manual) exposure actually used the correct settings for broad daylight.
But if your intent is to severely crop the result, why not just switch the camera to Dx mode and aim more carefully? If you do that you will be able to use an aperture of f/5.6.
The raw file with be less than half the size of an Fx raw file. and you will be able to adjust the exposure and ISO to get less noise.
As for Auto ISO, if you are shooting in broad daylight you simply don't need it. Just use Sunny 16 (LV 14.7) or 1/3 stop darker as you did in your M mode exposure. This will always work for the whitest feathers even in sunny Florida.
