I'm curious which one of the images was flipped to create the impression they were looking in different directions rather than the same direction?

It is not relevant. One was flipped so it is easier to compare differences. Hence 'versus'.

Great detail. I often see Anna's in my backyard, occasionally Rufous when I am eating breakfast.

Great close up comparison, Tony!
Your birding skill is amazing, and the 150-400mm is just a jewel of a lens.
Also, given the level of fine detail in these two images, both shot at f/16, it confirms my opinion that diffraction is not a legitimate issue until you exceed f/16 on m4/3's. I have seen countless comments elsewhere that f/8 is the upper limit for m4/3's -- to that I say "nonsense".

At f/16 the Airy disc is 21.5µm, huge compared to the 3.3µm pixel pitch. If that is not diffraction I don't know what is. Of course most people use small apertures sometimes when DOF is more important than resolution and the modern software does a good job of interpolating missing info.
