Bill D,
to answer your question about size...I was working on a small subdivision pond this summer in north Atlanta. I was in a hurry but stopped to watch this scene. A heron had stabbed a bass over 18 inches (no exagerration) over 3 lbs. I said no way is he going to try and eat that. It took him holding it upside in his mouth bass head first about 5-10 mins then he suddenly shot his head up and swallowed it down. I charged him and could hardly flop much less try and fly away. SO yes at least on occasion they eat fish of substantial size. I do not tolerate them on my ponds. One took out 18 grass carp over a two week period 18x$7= $126 the heron has to go.
