This Country Gardens Fountain Birdbath is made from lightweight resin with a cast stone weathered finish. Using state of the art solar panel and solar pump technology, power is supplied to the fountain from natural outdoor sun and light. The solar panel is built In, residing in the water basin itself. The 6 volt solar pump in the bottom of the basin, beneath the built-in solar panel, continuously circulates the water up through the center spout, creating water movement and gentle babbling water sounds. The birds love it, and so will you. This fountain includes everything you need, is self contained and needs no installation. It will give you many years of soothing joy.
