The idea behind decoys is to ward off predators and other unwanted guests from your pond. One thing to remember is to relocate the decoy so it seems it does move around. Meaning if left in one spot it could become a fixture or statue that won’t really startle whom we are trying to ward off. This is very life like and can fool our own eye. If you forgot that it was there and you come home from work and see this Blue Heron at the pond you’ll perk up but then the memory comes back. Protects Koi & other precious fish from herons, makes a great decoration too. Measures: 23˝L x 7˝W x 29˝H. Click the pictures to enlarge.
