If you're looking for a birdbath that can spray a continuous stream of water and operate without any plugs or electricity, there are several products available that can do that. The solar-powered birdbath will let you create a delicate centerpiece for your garden without having to deal with running electricity to your unit. You can choose from versions with the classic lines of a Greek column or a sleek version more suited to a Japanese garden. A solar-powered bird bath typically has solar cells embedded in the fountain bowl which will absorb the suns rays to power the spray of water. You can also find versions which simply re-circulate the water, keeping it in constant motion.
