John, superb presentation and birds! Your presentation allows one to open and arrange the two birds as tabs in separate browser windows for all the male and separately all the female images. Looking just at the 1:1 details around the eyes and head feathers, it's hard (if even possible) to say there's a difference between the 300mm and the 600mm images that is 'different' due to the lens configuration rather than slightly different views and lighting.
For the male, I think the 600mm is the best of the three, with just the slight increase in ISO grain.
I know it won't happen, but I would be happy to see these examples put an end to the rampant UHH urban myth of the limitations of using extenders, especially the 2x variety. To my eyes the 1.4x was the slight difference, but only for the male, where his example was slightly less brightly lit, maybe impacting the AF performance rather than the extender.

Thank you very very much Paul for such a complete response. Male cardinals present a special problem for getting feather detail at times. Light and light angle as you mentioned play a roll. Also when the feathers are flatten down, and the red is so saturated the detail is hidden. Hope to be shooting raw soon which I should help, but need a new computer and waiting for my second COVID shot before going shopping.
