 So there's solar fountains that you can add to your birdbath, water wigglers that will make the water have some ripples to it, or misters that'll just provide a lovely fine mist, which hummingbirds love. And also, we also have a new thing. It's a copper disc, and you put that in your birdbath. And copper is an antibacterial. So when you put it in, it keeps your birdbath, it keeps the water cleaner longer.
