Tony,
I know that in Texas and Louisiana we have special regulations on "water turkey" the double crested cormorant, you can't shoot the anahinga (not sure if that spelling is 100%. First contact your local state wildlife agency and get the regulation befor you go to blasting water turkey. Then if its OK the liberal shotgun method works best down here (any friend with a shotgun around your pond shooting water turkey) The increased commotion will help, but not eliminate the Heron problem. They are protected everywhere. I never have a problem finding someone to drop by to take a few practice shots. The water turkey are much more of a threat to your fish than are the Heron anyway. Happy Hunting!!! (if its legal)
