that is the best natural solution, cross it 15' above water and you can get rid of Kingfisher as well.
Along the shore line, it will discourage herons and geese.
Works well around here anyway! good luck!
I respectfully disagree. When I used monofilament line I ended up getting morning doves tangled in it by their wings. I prefer not to deal with that.
