What a great series! When I look at that big fish (#2) it seems like its too big to be swallowed, but they have no problem. Great details in all your shots.
Steve, you are right, the blue heron in # 2 did not swallow the fish, which was too big to be swallowed, he gave up, and continued to look for the smaller ones.
Awesome series, the last shot is beautiful. I have been trying to get close to these guys here in Minnesota, but even with a kayak, they are very easily spooked. Well done.
