Kevin, I really like this bird and the wonderful interaction you've captured - your timing was excellent. If the shot had been mine, I would have done a tighter crop all around particularly cutting on the right, top and bottom (latter would also help by removing some distracting twigs in the bottom left). There are some minor issues with blown color channels. At the moment, parts of the lower yellow flank of the left bird is blown in the red channel. Same is true to a lesser extent with the yellow tails, the white on the left bird and some of the highlights on the twigs. Moving the white point further to the right in the RAW processing and darkening highlights might do the job. I also agree that the dark parts of the birds' faces could benefit from being pulled up a little. You could also try pulling back the overall exposure just a whisker in the RAW processing? In making these adjustments, the risk is flattening the contrast too much so localised adjustments via selections might be needed. Overall, these are minor points though - I still think you've got a great shot here.
