Things You'll Need
Instructions
Dig your pond as deep as you can if you have not dug it yet. Herons stand in shallow areas of the water to search for their meal. If a pond is deep, fish have a place to hide and herons cannot eat them.
Put a fence around the pond. This deters birds from entering the pond from the banks. Some persistent birds may land directly in the water, though.
Put up a water scarecrow, a sprinkler that attaches to a house. When a bird flies past the motion sensor, water sprays over the area. This frightens the bird away. Some birds will get used to the water and might ignore it.
Place a decoy near the pond. Use a decoy that resembles the bird that is bothering the pond. A decoy's purpose is to scare away troublesome birds. During mating season, though, some birds may not mind the decoy.
Tie blackbird netting over the water of the pond. Place the netting high enough so that a bird cannot reach fish through it.
Play loud music when you see a bird come near the pond. The noise startles the bird, and it usually flies away. Yelling at the bird sometimes works, too.
