Legends of the Jersey Devil go back to colonial times and before. The creature is generally described as bipedal, with large bat wings, hind legs that bend like a cranes, hooves, and a horse or dog-head. The size of the devil varies from three to seven feet tall, and the color varies as well (with white the most common.)
Eye witnesses also describe a loud scream, "like a train wreak."
