I've been having a blue heron visit my pond. After seeing him fly off this morning, I decided to fight back. Went to Wal-Mart and bought 2 dozen 4-foot bamboo stakes and some fishing line, I made fence around the pond with fishing line at three levels. Let's see if he succeeds at having another meal a la my pond. My poor fish have been in hiding lately which is a shame since my pond is clearing up nicely. It's been either that I can't see the fish due to muck and algae or I can't see them because they are in hiding. Can't win.
