I found that the 2 foot high chicken wire kept it from walking into the pond, just put at any area it could walk in. The floating gator heads, did even a better job. It would not even try to get near the pond, just stare at them, circle the pond and walk out into the yard and eat bugs. Two different looking heads.
Both tied to a rock on fishin line so they moved in the breeze, constantly moved, one at each end of the pond.
I do have one piece of netting over the pond, due to the size of my pond one could fly in and land at the "walk out end" With that one piece of netting down the middle, it can't fly in, they need room with that wing span.
I have been seeing it fly over almost daily, high up, going west in the evening east in the morning, but it has not done a stop by.
