These are nice shots, but they lack sharpness to me, with the exception of the Western Tanager and the Barred Owl. Here's what I think may have happened with some. The AF frame was was not on the head or eyes. My expectation is always sharp head feathers and eyes (at least). Take, for example, the Eared Grebe shot. It's pretty clear that AF was on the back but not on the head. You captured the head and details, and did a decent job, but the head and details just aren't as sharp to me as the back and details (like the water droplets). Good luck!
