Dear Shanks: I was too much influenced by mention of genes
somewhere in the discussion. "If your're not confused, you just don't understand the situation." One experience I had a long time ago might fit. A neighbor whose garden was being robbed by starlings asked me to shoot them. They flew over a small building, behind which I could hide. I shot a couple dozen of them, and then bird started making detour around our property. Five years after the last time I shot one, the starlings were still making the detour around our
property. Would that fit? I'm just not able to master some of these lengthy discussions. Thanks for trying to help me. Bill
