Fishing line fence for heron problem?
A great blue heron has appeared for three days in a row. I think the first two days I scared him away before he got in the pond, but today, I know he got in, because (what's left of) the fish are hiding. I have had a heron decoy for years, and have moved it three times in the last three days- doesn't seem to help.
A local pond expert suggested a 1-foot high fishing line around the pond, because the heron is a wading bird, and that will keep him from getting in the pond. Has anyone heard of the fishing-line solution?
I won't be able to get to that until Friday (the day after tomorrow.) Last year I had an unseen heron visit, and made a safe-house for my fish out of a milk carton - so I hope that is where they are now. I also worry about my frogs.
