I swear by the motion sprinkler, but you may have to put netting up for
awhile, since the heron has fed. Most deterrents work best before the bird
has been rewarded. And if Kathy didn't mention it in her list, fake fish,
drives them insane. ~ jan
=====================
The herons here took the fake fish one time,... learned their lesson and
went back to the real fish ignoring the fake completely.

Either your herons are very very smart or your fish very dumb. ;o) Once a
bird strikes the fish are suppose to dive for cover. The fake fish should
be securely tied down so the bird can't remove and exam it. ~ jan
