Personally prefer this crop b/c I get to wonder what else may be out of frame behind 2nd bird flying with the leader. However, highlights below are attracting eyes away from subject and dragging them off the frame so I would test 2 more post edit modifications: Darken the foreground a bit to reduce (not remove) the distraction (maybe vignette style); And possibly a little bkgd work but wait until the first issue is improved so you can see if that also affects the bkgd. If it did not affect the bkgd, a little more blur might help pop the subject a bit more and separate the head/beak better from the bkgd. Caution to not lose the wonderful colors in the bkgd while blurring. Then subtle lighting increase on the neck of the lead bird to better attract viewer eyes. In summary, notice how your eyes first go to the subject, see the highlights on the wing fronts, then go to the highlights on the wing fronts of the other bird, then get attracted to the all the white in the bottom of the image, then fall off the bottom of the image. "Reasonable" edits you can make to keep those eyes on the main bird is the objective. Disclaimer: All this is IMHO only and may be not at all what you prefer.
