Hi Steve - Great shots, the Red-headed Barbet for me is the best of the lot.I've been watching Glenn's study progress in photography.He has has a great Mentor in your self. I'm curious are you using the Canon 400 5.6 in most of your shots? I just sold my 400 5.6 & now I'm using a Sigma 50-500 with OS which I like a little better, but 400 L 5.6 is a great lens. I envy your trip to the wilds of South America.
