Hey Roomie, You were supposed to e-mail me a link
Glad that I found this. I have many questions and lots to say.
#1: Were you handholding?
(Ah, I see that you were on a tripod. That is good. With decent technique, you should be fine with static subjects like these at 320 sec. I will often shoot at long focal lengths -- 840mm and 1200mm, on a tripod, as low as 1/60 sec.)
#2: In DPP, you can see the active AF points.
#3: How do you know where the AF point was?
#4: In Pane #3, You say, "This is the original." In what form is that image?
#5: The color of the image in Pane #3 is far more natural than the color in the original post. The OP is overstaurated with a large YELLOW cast.
#6: I like the raised foot of the bird on the nest but that bird's head is turned away from us :-(. That is, poor head angle.
#7: Do you have my R5/R6 guide? I helped a lady set up her R6 II and she learned to use it in 10 minutes with 100% confidence in the AF system.
#8: With mirrorless, you need to watch the AF points to make sure that they are where you want them.
#9: Steve's repost in Pane #4 looks much better than the OP and the eye of the nearest bird appears to be fairly sharp. (See #1 above.)
#10: Here is a great refresher course:

#11: Send me the raw file.
#12: Be sure to answer all of the questions above to maximize learning.
#13: I added this one after I saw that you were on a tripod. With the bird on the nest at least a foot behind the bird in the front, no amount of d-o-f would have gotten then second bird sharp without making all the leaves disgustingly sharp and you would have needed and ISO of at 256,000. Not advisable. I've been advising bird photographers for > 30 years: Shoot wide open and get the eye sharp (unless you can verbalize a realistic reason for stopping down.
