I finally got out yesterday afternoon and took some shots.
200 mm is way too small for birds, but the few I took were mostly in focus, except for those sitting in trees with all sorts of tiny branches interfering with focus.
It worked very well with my dog Joe when I threw a dummy for him. I took more than a few shots at 20 frames per second and they all had one thing in common, they did
NOT show him as a black object with no detail. Instead, he was well exposed with all of the detail I could ever want.
I picked one I liked and developed it. Very little change from the RAW file, including no cropping.
