Michael - I really like this. I'm a big fan of including habitat in a shot and this works for me. It tells a complete story. Exposure looks fine to me and it's certainly sharp, well done.
Nice detail and exposure. Not an ideal head angle, but acceptable. I would crop a bit more at the bottom to remove some of the OOF vegetation. I would also suggest darkening some of the bright spots in the BG above the bird's head and below its neck.
I like this one alot. Great feeding behaviour, and I love that we can see inside the mouth as it is about to swallow the food item. Great low angle. I'm OK with the amount of FG vegetation, but I agree on toning down the brighter spots near the head and neck.
Michael, I love the pose w/ the open mouth. The image has such a nice innocent feel to it. Nice inclusion of habitat. I agree w/ Daniel regarding some bright spots.
