Its the time of year again when a pair of mallard take up

vandalise all the plants in baskets and eat all my frog

I am thinking about running a single strand of electric

I think I'm with Chip, seems the current would go into the water as it
passed thru the duck.

If you located where it isn't freezing a motion sprinkler would do the
trick. If freezing.... bird netting? ~ jan
