My idea of ultimate enjoyment is to get on the upwind side of the pond right at dusk and throw out some pellets, then try to ID the fish as they feed by the type of splash they make. The BG are pretty easy to tell from the HSB. I have one lonely CC and LMB that will occasionally feed as well. When you only have one LMB in a 1.5 acre pond you tend to have a high variety and density of frogs. Sometimes I can tell there are as many as six different species of frogs. I can't attach a sound to a face, though.
Love your post, Meadowlark.
