Wildlife isn't filled with static objects.

EXACTLY!!!  That's why there is so much room for illusion in examining results.

People will drool over a sharp- and clean-looking bird that is only 4 inches long on the monitor at 100% pixel view, and "meh" at 20-inch birds at 100% that give some peek into the fact that the lens is running out of resolution, and pixel noise can be seen, when in fact, the latter may be much better than the former at any common size; 4 inches, 20 inches, 17 inches, 3.4 inches, 27.8 inches, etc, for both at the same time.
