A whirligig is an object that spins or whirls, or has at least one part that spins or whirls. Whirligigs are also known as pinwheels, buzzers, comic weathervanes, gee-haws, spinners, whirlygigs, whirlijigs, whirlyjigs, whirlybirds, or plain whirly. Whirligigs are most commonly powered by the wind but can be hand, friction, or motor powered. They can be used as a kinetic garden ornament. They can be designed to transmit sound and vibration into the ground to repel burrowing rodents in yards, gardens, and backyards.
