Thank you very much for your kind comments. I will see on the vertical crop - I have also these photos but they are not processed yet. However, yesterday I will take other photos of the same nest (13-days old nestling).
Wonderful family moment captured, and you did a great job getting good head angles on both the adult and that adorable chick. Good use of flash. Add another vote for a vertical crop, perhaps including more of the bottom of the nest. I'm looking forward to seeing more images of this pair.
