A couple of friends and myself were standing out in the back yard next to pond yesterday and the heron question came up. So far I have not had any visits from any heron, and we all agreed it is because of the incloser of six foot fence and all of the overhead wires. We have power line, and phone lines that every which way across the back yard and over the pond. We concluded that if a heron did manage to land, the critter would not be able to take off quickly if it had to.
Happy ponding,
