Heres a few notes collected from observations and other folks

When I plant strawberries I also plant some red stones. Birds peck atthe
stones, learn the error of their ways and don't come back for
thestrawberries... hopefully. I wonder if a concrete koi, placed at an
easy to get to area, would
tempt a heron. A few strikes at that could discourage a heron and might even
teach the other koi to run and hide
I tried both....neither worked Jerri
