James,
These are shot at the Farminton Bay area off the Great Salt Lake. It's a crazy place because you can have 50 or so eagles flying about yet look a mile or so off and see the interstate and the mass of homes crowding the Wasatch front area.
The lens takes good technique but can deliver. Of course for the first time ever, I sometimes have too much lens as shown with these two uncropped images.
A couple of more from today, the light was finally good.
Hoping for similiar results tomorrow. I want to concentrate of the interaction of the birds tomorrow versus so many feeding shots.
