I saw a motion activated sprinkler that scares birds away and it looks like it would work but...I don't want my garden hose on all the time.\nI was thinking of a pump in the pond that is motion activated. The spra would be on the edges of the pond pointing toward the center. The spray would be like a fan spray. It would come on for a few seconds like a motion light. Just enough to frighten away a bird or cat and the water would just return to the pond.\nDo yall think that is doable? Or ya think it would work at all? Has it been tried before?
