Wind powered, these kinetic airplane sculptures bring a touch of whimsy and fun to a backyard or garden. When the wind blows, the action starts - the prop spins and the animals move. Originally these were used to deter gophers and moles with the vibrations through the pole generated by the spinning props. The Whirligigs comes with 3-part pole, easy to assemble. Great gift for aviation fans, animal lovers and gardeners!
