Decoy Heron should be placed next to your water garden. The best time to put the Heron/Crane out is late May after the mating season. If you put them out before it maybe attracts a live mate. Herons are very territorial birds, when the Decoy Heron is placed other heron will avoid your pond and find a different food sores. You can move your Decoy Heron once in a while to different spots to make the live Herons think they’re real.
