Protect your fish with a Blue Heron Decoy. Herons are very territorial birds; when the decoy is placed near a pond, other Herons will avoid conflict and find a different feeding spot! This Blue Heron Decoy deters problematic Herons from visiting your pond and doubles as a realistic Blue Heron pond decoration. The Blue Heron Decoy should be moved regularly for the best results. It is constructed of durable injection-molded plastic and includes detachable legs and a mounting stake.
